Telescoping Bridge Crane

1. Product Introduction:
 

Telescoping bridge crane are designed with high configuration, which is developed with advanced design technology . Telescoping overhead crane are mainly made up by main beams, end beams, trolleys, electrical parts and control rooms and other components.

 

Telescoping bridge crane newly developed overhead crane are with compact layout and modularized structural design allows effective use of the available lifting height and reduce the investment on the steel structure of workshop.

3. Component:
 

Telescoping bridge crane consists of metal structure, electric hoist, running mechanism, electrical equipment, etc.

 

Metal structure part: The main girder usually adopts a box-girder structure, using a welded box-shaped main girder, and the trolley track is arranged on the top and side of the web of the main girder.
 

Electric hoist: The electric hoist is attached to one side of the main girder and moves longitudinally along the main girder, which increases the service space of the hook and reduces the height and cost of the workshop. For its structural characteristics, please refer to the manual of the electric wire rope hoist.
 

Operating mechanism: This product adopts the form of separate driving, It is completed by the cone brake asynchronous motor, and the reduction device adopts the "one opening and one closing" gear reduction transmission.
 

Electrical equipment: The supporting motor is a conical brake asynchronous motor. The electric hoist and the whole machine are equipped with safety devices, such as: lifting limit switch, limit switch at the end of the cart, etc.

 

4. Applicable Environment:

 

Telescoping bridge crane are widely used in workshops, warehouses, stockyards, etc. in machinery manufacturing workshops, metallurgical workshops, petroleum, petrochemicals, ports, railways, civil aviation, power stations, papermaking, building materials, electronics and other industries. It has the advantages of compact dimensions, low building clearance, light weight, and small wheel pressure.

 

5. Wearing Parts:

The wearing parts of telescoping bridge crane include b brake, limit switch, buffer and hook safety.

 

6. How to operate

 

There are two modes of operation: ground and air. There are two types of ground operations: corded handle operation and remote control handle operation; aerial operation refers to driver's cab operation. The driver's cab has two types: open type and closed type. It can be divided into two types: left or right installation according to the actual situation. There are two entrance directions: side and end, to meet the user's choice under various needs.

 

7. Benefits

 

① Improved Efficiency

 

The telescoping overhead crane provides businesses with an efficient way to move heavy loads, which results in expedited production schedules and increased output.

 

② Savings in Labor Costs

 

The crane eliminates the need for manual labor, which results in significant savings in labor costs. It can handle heavy loads without requiring human intervention, enabling the operators to focus on other tasks.

 

③ Increased Safety

 

The safety features of the crane ensure that there are no accidents or injuries in the workplace. By ensuring the safety of the equipment and personnel, businesses can save on expenses related to worker compensation and legal liabilities.

 

④ Low Cost of Ownership

 

The low cost of ownership makes this crane an attractive option for businesses looking for a cost-effective way to improve their lifting capacity. The minimal maintenance required results in reduced expenses associated with maintenance and repair.

 

8. Precautions

 

(1) Each Telescoping bridge crane must have a rated lifting capacity sign posted in a conspicuous place.

 

(2) During work, no one is allowed on the bridge or anyone is allowed to be transported with a hook.

 

(3) Telescoping overhead crane is not allowed to drive a crane without an operator's license or after drinking.

 

(4) You must concentrate during operation, and you are not allowed to talk, smoke or do irrelevant things.

 

(5) The vehicle must be clean; equipment, tools, flammable materials, explosive materials and dangerous goods are not allowed to be placed randomly.

 

(6) Overloading of the crane is not allowed.

 

(7) Lifting is not allowed under the following circumstances: weak bindings; overloaded machinery; unclear signals; diagonal pulls; objects buried or frozen in the ground; people on the objects being lifted; flammable materials and explosive devices without safety protection measures and dangerous goods; overfilled liquid items; wire ropes that do not meet the requirements for safe use; and the lifting mechanism is faulty.

 

(8) When the telescoping bridge crane is operating on a line without obstacles, the hook or spreader and the bottom of the hoisted object must be at least 2m above the ground. If crossing an obstacle, it must be 0.5m higher than the obstacle.

 

(9) For lifting objects that are less than 50% of the rated lifting capacity, two mechanisms are allowed to operate at the same time; for lifting objects that are greater than 50% of the rated lifting capacity, only one mechanism is allowed to operate.

 

(10) For telescoping overhead crane with main and auxiliary hooks, do not raise or lower the main and auxiliary hooks at the same time (special exceptions).

 

(11) telescoping bridge crane is not allowed to weld or hammer on the lifted objects or work under the objects (it is allowed when there is support).
