Features of 20 ton overhead crane

Double girder 20t crane is a great solution designed to carry medium and heavy duty loads. By using two adjacently positioned beams, traveling bridge crane offers improved support for the goods being handled, allowing the movement of larger capacities.

Product detail description:

1. Strong beams: the crane beams are of welded construction.
This result in lower dead weight with a high degree of vertical and horizontal rigidity and smaller wheel loads.
2. End carriage: crane traveling system, motor reducer-wheel driven system. The motor uses soft start motor which results in very stable starting.
3. Durable performance and high efficiency.
4. Modern cabin control with air conditioner can separate operators from harsh environment.
6. Long service lifespan with a low-maintenance.

Safety features:

1. Overload protection: if the materials or electric current overstep the capacity, the crane will give a sharp warning for protecting itself.
2. Emergency brake: if there’s emergency situation, it could stop the crane to protect operator and goods.
3. Control method: room control or remote control can avoid any injury to the operation staff.
4. Main lifting motor: with thermal protection and currency protection.
5. Hooks with latch: to prevent goods fall down.
6. Rubber buffers.

Operation model: ground handle, remote control and cabin (open and closed)

Load handling device: the crane can also be furnished with motor grab, electromagnetic chuck according to the requirements of varied types of materials.

Top running overhead crane options in Pakistan

Cabin control overhead crane. The operator sits in the cabin, moves together with the crane, and has good clear view. The cabin can protect the operator from noise, damage and dust.

Remote control overhead crane. The crane is operated from a distance, the operator’s exposure to potential hazards in the typical operating environment is reduced. An operator’s cabin and access ways to it are no longer necessary, leading to potential cost savings.

Accessories of warehouse crane system

Hook often hangs on the wire rope of lifting mechanism by means of pulley block and other components.

The reel group is a part of the winding rope in the lifting mechanism and the traction mechanism.

The brake has the function of stopping the falling of the suspended object and stopping machine movement.

Overhead cranes mainly have main girders and end beams.

After the crane is introduced into the power supply from outside, it will be allocated to the various electrical parts through the distribution box, and the electrical protection of these electrical equipment is necessary.

For reducer, its main function is to transfer the high speed of the motor into the actual speed required by the crane’s various mechanism, and to obtain a large torque.

An electric motor is a device that converts electrical energy into mechanical energy, so that the crane can run normally vertically or horizontally.

How to save overhead crane cost?

Whether to buy single girder eot crane or double girder eot crane, overhead crane prices influence the purchase greatly. Everyone wants to buy a reliable workstation crane with factory price. To get a suitable portable bridge crane, customers should be clear about the crane parameters, such as lifting tons, lifting height,crane span, and other basic information, working condition, special needs. In addition, professional industrial cranes manufacturer can help save much cost and provide sincere service. The last, take daily check work for cranes. This can prolong the crane service life.

How to ensure overhead traveling crane safety?

Industrial overhead crane is widely used to transport, assemble, check and repair as well as load and unload at workshop, warehouse and goods yard. For heavy duty crane with application, the safety becomes important.

The operator should use indoor mobile crane according to the rules. Correct operation can reduce accident rate, protect the crane and the operator from damage.

For any abnormal conditions, the operator should stop working, to check the crane careful for finding the problem and solving the problem in time.

Overhead rolling crane is kind of large lifting device. It is safer to equip the crane with complete safety protection devices.

Our company specializes in kinds of lifting devices, gantry crane, jib crane, marine winches, construction winches, mobile boat travel lift, electric hoist, material transfer trolley. If you are interested, just contact with us! sales@crane.pk.
