Cranes

Cranes are powerful lifting machines which can lift and hold up to 300 tonnes. And because they are used for lifting heavy items and objects, you need to be extremely careful in order to avoid accidents. The number of crane-related accidents continues to raise every year. These accidents happen as a result of poor training, overconfidence and lack of attention. Therefore, there are some regulations that operators need to follow. Cranes are not only dangerous machines, but also can cause costly damages on the job site. Due to that, OSHA (occupational safety and health administration) developed a set of safety standards that every crane operator needs to follow. Let’s see what needs to be done for safe crane operation:

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.

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:

  • 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:

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.

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. Depending on the construction project, you have a broad range of different construction equipment on disposal. With proper equipment, you can easily and cost-efficiently complete any given task. There are compact machines, but most of them are extremely large and difficult to use. To choose the right equipment for your construction project, you need to understand the most common construction machines and equipment, and for what applications they can be used for.

Lifting: Cranes – Cranes are essential machines for any construction project, because without them the tasks that involve lifting heavy items and materials would seen impossible. Despite the wide range of different crane types, the boom cranes are the most popular choice for many people involved in the construction industry. The boom cranes are designed for lifting heavy loads and to reach areas on incredible heights. So, the boom cranes are most commonly used for lifting the heaviest equipment and materials on any construction job site.

Digging: Excavators – Like the boom cranes, the excavators are also commonly used machines for various construction projects. These flexible and versatile machines are used for a variety of applications, like digging trenches and holes, setting foundations, cutting jobs, material handling, demolishing jobs, forestry jobs and landscaping. The excavators play a vital role in the construction industry today, as they are efficient for many applications.

Loading & Moving: Loaders – Boom cranes for lifting, excavators for digging and loaders for both loading and moving. The loaders are very efficient construction machines which can be used for a variety of jobs. The loaders come in different configuration for performing different applications. Wheeled or tracked, with the bucket in front or at the rear, and with many different types of attachments, the loaders are important equipment for any construction project.

Mixing: Concrete Mixers – Many construction projects require large amounts of concrete. Unlike in the past when people mixed concrete manually with shovels, today the construction workers can produce large amounts of concrete with concrete mixers.

To sum it up, every construction project requires a specific set of construction machines and equipment. Boom cranes for lifting applications, excavators for digging applications, loaders for loading and moving, and concrete mixers for concrete mixing applications.
