Types Of Overhead Cranes

Storage Bridge Crane

 

The QZ types of overhead cranes is suitable for warehouses and workshops of metallurgical minerals, chemical cement and other enterprise factories. It can be used indoors or in the open air. It is mainly used for ore, limestone, mineral powder, coke, coal sand and other granular materials. In addition to handling work, the QZ-type double-girder bridge grab crane is widely used in power plants, cargo yards, workshops, docks, etc. for loading, unloading and transporting bulk materials. This machine consists of five parts: box-shaped bridge frame, cart operating mechanism, trolley, grab bucket, and electrical equipment.

 

All mechanisms are controlled in the control room. This QZ types of overhead cranes is a heavy-duty working system with a working level of A6. The lifting capacity includes the dead weight of the grab. The QZ types of overhead cranes relies on longitudinal movement along the direction of the factory track, lateral movement of the trolley and lifting movement of the hook. working. The operating environment temperature of the crane is -20~+40℃.

Classification of grab specifications and models

 

Grab is a commonly used construction machinery accessory, which is widely used in various construction, agriculture, mining and other fields. According to its structure and use, grabs can be divided into the following types:

 

1. Angle iron grab: suitable for light-duty operations, such as cleaning the construction site, collecting garbage, etc.

 

2. Ordinary bucket: suitable for general operations, such as earthmoving operations, mine transportation, etc.

 

3. Reinforced bucket: suitable for heavy-duty operations, such as digging hard soil and stones.

 

4. Trench type grab: suitable for excavating underground trenches, drainage ditches and other occasions.

 

5. Stone cube bucket: It is suitable for digging hard materials such as stone cube and coal.

 

6. Grapple hook: suitable for loading and unloading goods, cleaning waste materials, etc.

 

 

The retrieval device is a double-roller four-rope grab with a simple structure and efficient operation. The grab can be opened and closed at any height. The effect is good when the captured material particles are below 100mm. When the captured material particles are larger than 200mm, a toothed grab should be used. The grab opening directions include parallel and straight main beams.

 

The grab bucket is only suitable for naturally accumulated bulk materials. When grabbing underwater materials or special boring situations, please make a special request when ordering. Waterproof equipment is required when using outdoors. All structures are operated from the cab. The directions for entering the cab platform door are: end entry, side entry and top entry. This crane can be used indoors or outdoors. When used outdoors, a rainproof cover device is added.

 

 

QZ types of overhead cranes safety operating procedures:

 

It is not allowed to hang in the air for a long time, and personnel are not allowed to leave their posts when hanging objects.
 

A QZ types of overhead cranes is a multifunctional hoisting machine that can lift and carry heavy objects vertically and horizontally within a certain range, also known as a crane, aerial crane, or hoist. The main parameters of the crane are the parameters that represent the main technical performance indicators of the crane, are the basis for the design of the crane, and are an important basis for the safety technical requirements of heavy machinery.

Do not work after drinking, and do not chat during work.
 

After the work is over, the QZ types of overhead cranes should be driven back to the left side of the gate, and the operation button switch should be hung at the designated position.

 

When hanging the operation button switch, you should pay attention to how to hang it before removing it, and how to hang it when you put it back, so as to prevent rainwater from flowing into the button switch.
