Crane Accessories

Crane accessories are extra parts or attachments that can be used with a crane to improve its performance and modify it to meet particular lifting needs. These add-ons offer flexibility, safety, and effectiveness in a variety of lifting activities.

Here are a few typical crane extras:

1. Slings are used to secure loads and attach them to crane hooks. Rigging equipment is also used to secure loads. They occur in a variety of forms, such as synthetic, wire rope, and chain slings. Shackles, hooks, and turnbuckles are among the rigging tools that are necessary for secure load attachment and lifting.

2. Spreader Bars and Lifting Beams: Lifting beams and spreader bars are both used to distribute the weight of a load among numerous attachment points. When lifting activities are being performed, they assist in maintaining stability and balance, particularly when handling long or unevenly distributed weights. Different load widths can be accommodated by adjusting the spreader bars.

3. Lifting Magnets: To raise and move ferrous items like steel plates, beams, or pipes, lifting magnets use magnetic force. Without the use of slings or other rigging tools, they give the weight a firm grasp. Lifting magnets are frequently employed in steel production plants, scrap yards, and the metalworking industry.

4. Grapples and Clamshells: These specialised attachments are used to handle loose bulk objects like boulders, logs, garbage, and other debris. Grapples have claws or hinged jaws that can close in on a load to give a firm grasp. Clamshells have two movable shells that can be opened and closed to sweep up objects.

5. Coil lifters and C-hooks: C-hooks are made specifically for lifting and moving coiled objects like steel coils or paper rolls. They are curved, which cradles the coil and makes it safe to carry and transport. Another kind of attachment for handling and lifting rolled or cylindrical materials is the coil lifter.

6. Outrigger pads, often known as crane mats, are substantial mats positioned beneath the crane's outriggers or stabilisers. They offer a solid foundation and spread the weight across more land, preventing the crane from sinking into soft or unstable ground. Crane mats guarantee proper weight distribution and increase the stability of the crane.

7. Weighing systems and load cells: Load cells are sensors that gauge the weight of the object being lifted. They give operators precise weight data that enables the crane to operate within its safe lifting capacity. Cranes can be equipped with weighing devices that can track and show the weight of the load in real time.

8. Anti-Collision Systems: To avoid collisions between cranes or between cranes and other structures, anti-collision systems employ sensors and cutting-edge algorithms. These devices alert the crane operator visually or audibly when other cranes or impediments are nearby. They aid in enhancing safety and preventing accidents in busy workplaces when several cranes are working at once.

These are only a few types of crane accessories that are offered by the business. Depending on the precise lifting tasks, load characteristics, and operational safety requirements, crane accessories can be chosen. The best attachments for a specific crane type and lifting application can be advised upon by manufacturers and suppliers of cranes. 

Two parallel girders positioned on top of a runway construction make up a double rail trolley type crab, sometimes referred to as a double girder overhead crane. The trolley system used to move the crane along the runway operates on two parallel rails, hence the name "double rail trolley."

For lifting and moving heavy items, the two rail trolley type crab is frequently used in industrial settings including factories, warehouses and construction sites. In comparison to other crane types, it has a number of benefits, such as a higher lifting capability, more stability, and the capacity to cover a broader working area.

Among its main characteristics is a twin rail trolley style crab:

1. Double girder: Two strong girders that run parallel to one another support the crane. In comparison to single girder cranes, these girders offer more strength and stability, enabling higher lifting capacities.

2. Trolley system: The device that slides along the double rails on top of the girders while transporting the hoist is known as a trolley. It permits the load's horizontal movement, allowing for exact positioning.

3. Hoist: The hoisting device attached to the trolley is known as a hoist. A motorised drum or chain is used to raise and lower the weight. Depending on the precise lifting needs, the hoist's capacity, speed, and control options can be altered.

4. Controls: The operator of double rail trolley type cranes can control the crane's movement and hoisting operations using a control pendant or a wireless remote control. Advanced elements like computerised control systems and automatic positioning may also be found in some cranes.

The twin rail trolley type crab offers exceptional flexibility because it can effectively manage huge loads and a large operating area. In industries including manufacturing, heavy equipment maintenance, and construction projects, it is frequently employed in situations where a large lifting capability and precise load placing are necessary.
