Concrete installation is indeed a challenging job that requires a lot of time, hard work and effort. Many features need to be considered when pouring a concrete, including shape, size, colour, finish and depth.

Concrete Trucks

If centuries ago, ‘going concrete’ referred to many heavy-duty tasks performed manually (particularly when it comes to the mixture stage), today pouring concrete is performed quicker and easier all thanks to concrete trucks. Because of their great capacities for optimum performance, new concrete trucks enable concrete projects to run smoothly and be successfully finished on time.

There are few general steps to pouring concrete.

Step No. 1 – Site Work

Preparing the site is the first step that needs to be done before placing the concrete. That means that the area has to be cleared and cleaned of grass, trees, rocks, shrubs and old concrete surfaces. Afterward, a sub base of at least 10 centimeters in height needs to be placed and compacted over the area where the concrete layout will take place. Special attention needs to be paid to edges. Appropriate sub-base preparation is a ‘must-do’ to ensure the concrete fits perfectly.

Step No. 2 – Forming

Forms are ready to be set, once the sub base is properly prepared. When it comes to concrete forms, they can be made out of metal, wood and plastic, ranging in height from 10 centimeters and higher. Concrete forms are very important, as they indicate the area where concrete needs to be placed or filled. Normally, they are attached with special nails and screws that are easy to remove once the concrete has cured.

Step No. 3 – Placement

With a compact sub base and nicely set forms, it is time to finally place the concrete. And this is where the use of a concrete truck calls to action. Usually, the concrete arrives in a ready mix concrete truck, where the drum placed on the back of the truck spins slowly to keep the concrete from settling and getting hard. The mix truck pulls up to the site and pours right into the concrete forms. New concrete trucks come with additional features, such as rakes, shovels and the so-called ‘come alongs’ which make sure that there are no air pockets nor voids. New concrete trucks can be found both online and offline.

Step No. 4 – Finishing & Troweling

Once the concrete is filled within the concrete forms, a large wood or metal board is used to screed the concrete surface. After finishing this task, the top of the concrete needs to be troweled with a large trowel, also called ‘bull float’. The goal is to make a smooth finish that will give the concrete surface its final, brand-new look.

The invention of the ball mill introduced some significant changes in the mining industry. This machine is generally used for grinding different materials such as: ores, coal limestone, pigments, ferrous and non-ferrous metals. The newest ball mills are designed with advanced technology and they are used in other industries beside mining, such as: construction, metallurgy and chemistry. In these industry sectors, the ball mill has a vital role, because it has the power to reduce the size of large materials that are needed for further use.

Although highly efficient , the ball mills can be extremely dangerous machines if not operated properly. Therefore, the operators need to follow essential safety and maintenance tips which are usually listed in the manual that is provided by the manufacturer. This is the only way to ensure safe operation and long life span. The operators should take certain precautions before they start operating a ball mill. Here’s a list of the most important safety maintenance steps that all operators should follow when using a ball mill:

  • Planning – Planning ahead is a must. Operators should know exactly when to lock and stop the ball mill. Planning ensures proper coordination and cooperation between the maintenance and production departments.

  • Selecting The Crew – It’s very important to select the right maintenance crew that will be responsible for the maintenance schedule. Everyone needs to know exactly what needs to be done before and after every operation. In case something is not clear, employees need to turn to their crew leaders.

  • Issue Safe Work Permit – Operators must be issued a work permit before they start working with a ball mill.

  • Proper Technical Knowledge – Operators should receive proper technical training before they start working with a ball mill. They should fully understand how the ball mill actually works.

  • Barricading – The best way to avoid work-related injuries, is to barricade the area around the ball mill for safety reasons. It is also advisable to put signs that forbid entry without authorized permit. Signs also warn people of potential hazards.

  • Locking Out The Electrical Power – Once the ball mill operation is completed, the operator should disconnect the high-voltage electrical power. Operators should also test the circuit, once they are done with the task.

  • Clean Up The Machine After Use – A ball mill should be cleaned up after every operation or at the end of the working day. The main components, such as the grinding tool, grinding roller, and grinding ring are prone to wear and tear. Because of that, every part or component should be regularly lubricated and checked for damages.

The crane trucks are some of the most commonly used lifting machines. They can be found in many industry sectors where lifting heavy items is required. What makes them so popular is their ability to move easily from one place to another. Their versatility and flexibility makes them vital machines in different industries, including manufacturing, construction and even in the transportation industry. There are different crane trucks on the market, and each model comes with specific configuration and specifications. You need to choose a model that will best suit your needs.

Like any other heavy-duty machine, knowing how to safely use the crane truck is vital for maximum productivity on the job site. The major benefit of these machines is their mobility, making them very useful in construction places where bigger cranes cannot perform. For safe operation, there are some steps that need to be followed. Consider the following things when using crane trucks:

Operator and Workers Safety – People who operate with crane trucks are considered as responsible for their own safety and for the safety of other workers on the construction site. They must be trained to operate a crane safely, so they can avoid any accidents. Because the operator manages all parts of the machine, it is important to have certain knowledge and skills.

Certification and Training – There are specially designed courses and training programs for those who what to operate crane trucks. In these courses, operators learn how to operate with different types of cranes and how to perform different crane operations. Before getting the certification, they also need to pass the practical and written examinations.

Computer Control – Most cranes available on the market are equipped with a computer in order to boost the lifting calculations. The operator enters information about the load like height and weight. The computer also displays the movement of the loads. This system informs the operator when the load surpass the lifting capacity.

Cab Operator’s Controls – If you ever get a chance to enter a crane cab, you will see that there are two separate joysticks. One joystick is used for controlling the side-to-side movements, while the other is used for the forward-and-back movements. On the bottom there are pedals which are used by the operator for controlling the lowering, raising and the rotation of the boom. For increased safety, the newest crane trucks come with radio control system that allows the operators to use the machine remotely from a safe distance.

Job Site Inspections – When it comes to safe operation, proper use isn’t the only consideration. Another thing that is also very important is the job site. You should check and clear the path where the crane truck is going to be used before moving a load. The overhead power lines should also be well insulated. This way, unwanted accidents can be avoided.

With so many generator models on the market, choosing the right one can be a difficult task. In order to select a generator that is right for your needs, consider whether you need a generator for your business office, home, camping, remote job site or recreation. Defining the purpose why you need a generator is the first step for selecting the right generator. Generally these machines come in two main types: stationary and portable generators. The stationary models are usually installed outside. And because they work on natural gas or propane instead of gasoline, they provide clean energy.

The portable generators can supply power for different devices in your home when you are facing a blackout. Outside your home, a small generator can provide power for small appliances, like TVs, lights and power tools. These machines are ideal for camping. You can use medium or larger portable generators at construction sites in order to operate power tools like saws, drills, air compressors and paint sprayers. The small and middle sized models usually generate power from 3,000 to 8,500 watts. Most portable generators run on gasoline, but some can use propane or natural gas. The portable generators are less expensive when compared to the stationary models, and are easy to store and move.

Buying a generator is just the beginning. Some models don’t come with additional parts. Others might let you down when you need them the most. In addition, here are few simple steps to follow when looking for a generator for your home or construction site.

Reliability – Generators are machines that are categorized by wattage. The wattage determines how may appliances and lights you can run at the same time. Generator manufacturers produce high wattage machines for extra power which is required by some complicated electrical devices.

Which generator to choose – Decide what you need to power. If that includes an electric oven, dryer or a central air conditioner, you will need a larger and powerful generator. Also, think about the fuel. Most portable generators use 8 to 22 liters of gasoline per day. Look for some smart features. For example, some portable generators can be automatically turned off when the oil level is very low.

The portable generators are the biggest sellers on market. Functional and with innovative features, they are easy and safe to use. So, when buying a generator, here are the features to consider:

  • Alternative-fuel capability – Stationary generators often run on either natural gas or propane. When it comes to portable generators they run only on gasoline. However, some portable models can work on a natural gas or propane.
  • Oil guard – This feature protects the generator engine from failures by shutting down the machine when the oil level falls below the minimum. This is typical feature for the stationary generators, but also for some portable generators as well.
  • Wheels – You need only one person to move a portable generator that comes with wheels. But, if the machine needs to be lifted, you will need more help. Portable generators with pneumatic tires can be easily moved from one place to another.
  • Inverter technology – This is a common feature for the higher-end portable models. It makes the wattage output more consistent and smoother via microprocessor-controlled circuit.
  • Fuel gauge – The gauge allows you to check the fuel tank very easily. It is very useful, especially during extended power failure.
  • Electric starting – The modern portable generators come with start-stop button for easy engine operation.

Working with mobile cranes is not an easy job. If not operated properly, the mobile crane can be extremely dangerous machine. Most crane accidents happen because workers forget to follow the safety tips and regulations. The mobile cranes are generally used for heavy construction and demolition activities. Because of that, the operators should know when and how to use the hydraulic boom, since it is not designed to withstand too much stress and pressure. A mobile crane must have a proper falling protective structure (FOPS ) in order to protect the operator and the near workers from falling objects. It’s extremely important to always check the condition of the mobile crane prior each use. Here are some safety tips when a mobile crane is used:

mobile-crane-preventive-injuries

  • For ultimate protection on the construction site, the mobile crane should be operated according to the manufacturer’s load chart.
  • The mobile crane operators should know how to calculate the weight of each load. If the load is accurately calculated according to manufacturer’s manual, the chances for unexpected accidents are equal to zero.
  • A mobile crane operator should never measure the lift capacity of the crane by using visual signs.
  • When a mobile crane is used for lifting materials, the outrigger pads need to be placed on firm and stable surface. Cranes should be properly set according to the manufacturer’s procedures for proper outrigger deployment.
  • The mobile crane operators should always check the condition on the ground when they perform multiple lifts from one location to another. They must be sure that the crane is placed on a firm and stable ground.
  • Operators should never hoist or move suspended loads over workers within the swing radius of the mobile crane. They might lose control over the load and cause some serious injuries.
  • The work at the construction site can be very unpredictable. That’s why the operators should always take all safety measures before they start working with a mobile crane. One of the things operators must do is to barricade the area within the crane’s swing radius, and to stop unauthorized persons from entering the pinch points.
  • Kids under 18 are not allowed to operate a mobile crane, even when assisted by experienced operators.

When it comes to lifting equipment, the jib cranes are probably the most commonly used lifting machines. Armed with a moveable chain hoist, wire ropes, drum and a horizontal jib, these cranes are usually fixed either to a pillar or on walls. The jib cranes are perfect for lifting and lowering different loads with medium weights. What makes them to be widely used, is their ability to work in tight and confined areas. They are versatile machines and perfect solutions for many lifting applications. These lifting machines are capable to increase the work flow by lifting various items quickly and efficiently. There are different jib cranes on the market, and you need to choose the right model for your application. In order to choose the right jib crane, consider the following things:

jib-crane

Capacity – The first thing you need to determine is the lifting capacity. Usually, the lifting capacity of the crane is always higher than its weight. Determine what is the maximum weight that needs to be lifted in order to choose the right jib crane. This way, you will be sure that the job will be completed without injuries or accidents.

Boom rotation – When it comes to the boom rotation, there are several jib cranes on the market from which you can choose. You can choose between free standing and wall mounted jib cranes. The free standing jib cranes can rotate up to 360°, while the wall mounted jib cranes up to 180°. Have in mind the place where you will install the jib crane.

Jib cranes height – This is the distance measured from the floor to the boom, and it can be:

  • Height under boom – which is self-explanatory
  • Total height – the distance to the highest point.

Under boom height – Under boom height is the distance from the floor to the underside of the jib crane boom. This height will determine what type of hoist should be used for your application.

Jib boom outreach – The jib boom height can be:

  • Hook reach – the distance to the farthest point of the lifting load.
  • Boom span – the distance to the boom tip.

Installation – When it comes to installation, the jib cranes can be quite different. For example, the free standing cranes must be erected onto a concrete foundation or onto a reinforced, substantially thick concrete slab. On the other hand, the wall mounted cranes are usually installed against steel columns like hollow structural tubing, wide flange beam, walls and even monolithic concrete columns.

When injuries happen on the job site, the productivity is instantly decreased. That’s why many companies, especially those that use heavy-duty machines, implement safety procedures for preventing serious injuries. Many forklift truck injuries happen when people are working near the forklift. Proper forklift maneuvering is important to ensure safety for everyone at the job site.

For a proper forklift truck maneuvering, the operators need to posses special skills and knowledge. These skills can be gained only through training courses for forklift trucks. Bellow are some safety tips which can help you boost your productivity when using a forklift truck:

  1. Inspect the forklift truck before every operation. Perform a routine check of the equipment before using it. Some of the things you should check on a daily basis are: tires, brakes, steering, lifting system, mast, water and oil level, and battery.

  2. Wear appropriate clothing. Wear protective equipment such as hardhat, safety footwear, hi-visibly jackets. Depending on the work environment, additional protective equipment might be required.

  3. Choose the right forklift truck for the job. When choosing a forklift truck, you should consider the following things: capacity limits, potential hazards and the load requirements.

  4. Drive with caution. It is important for you to respect the speed limits, and also to sound the horn at corners and danger spots. Always drive to the right side of an aisle, stop before doorways, never carry passengers and be careful when driving and loading around pedestrians.

  5. Avoid tipping over. When carrying a load, it is important to keep the forks close to the ground and the mast tilted back.

  6. Be careful on hills and inclines. Don’t move heavy loads on sloppy and slippery surface.

  7. Never leave a forklift truck unattended. Always start the machine in neutral, with the parking brake on and the forks lowered.

Although simple, these safety tips can help you to protect everyone at the work site. 

Every industry needs specific equipment and machines for specific jobs and tasks. The equipment is essential for all industries, for some less, for other more. The construction industry is an industry that deals with heavy loads which cannot be lifted or moved without proper equipment.
