Single Girder Eot Crane

Single girder eot crane

 

The single girder eot crane is designed according to GB3811-2008 and JB/T1306-2008 standards and is equipped with electric hoist. It is widely used in machining, assembly, repair, warehouse and other workplaces. It is an important tool and equipment for modern industrial enterprises to realize the mechanization and automation of the production process, reduce heavy manual labor, and improve labor productivity.

 

It is used in metalworking workshops, assembly workshops, maintenance workshops, steel structure workshops and various warehouses. It can also be used for auxiliary lifting in metallurgical and foundry workshops. After considering the requirements of wind and rain protection and improving the design, it can also be used in the open air site.

 

Our high quality single girder eot cranes uses a three-phase 380V, 50Hz power supply. The common lifting capacity is 1-16 tons, the span is 7.5-28.5m, and the working environment temperature is within the range of -25°C to 40°C.

 

 

The structural features of the single girder eot cranes are as follows:

 

1. Metal structure part.

 

The main girder is U-shaped formed by steel plate rolling or welded into channel steel with steel plate, and then welded with I-beam to form a box-shaped solid web beam. For the convenience of storage and transportation, the main beam and the beam are made separately, and then connected with M20 or M24 high-strength bolts to form a whole.

 

2. Electric hoist.

 

The electric hoist can lift heavy objects and move longitudinally along the main beam on the lower flange of the I-beam under the main beam. The main varieties are CD1 and MD1.

 

For CD1 type, the lifting speed is 8m/min (when the lifting capacity is 10 tons, the lifting speed is 8m/min);

 

The MD1 type is a double-speed hoist with a lifting speed of 8 m/min and 0.8 m/min (when the lifting capacity is 10 tons, the lifting speed is 7 m/min and 0.72 m/min).

 

Standard lifting heights are 6m, 9m, 12m, 18m, 24m, 30m and so on.

 

There are two types of hoist running speed along the main beam: 30m/min and 20m/min, generally 20m/min.

 

3. Operating mechanism.

 

The running of the cart adopts the form of separate drive, and the braking is completed by the soft-start brake motor. The small tonnage is driven by a drive device, and the large tonnage can be driven by a "three-in-one" reducer.

 

A travel switch is installed on the end girder on one side of the bridge frame, so that the eot crane can automatically cut off the power supply and stop before running to the limit position at both ends of the track or before the two cranes meet.

 

The running electric hoist walks on the lower flange of the I-beam of the main beam, and the limit positions at both ends are limited by the buffers fixed on the web of the I-beam.

 

4. Beam crane operating regulations

 

① the maintenance crane must be specially trained and approved by the competent authority to operate.

 

② eot crane operators must be familiar with the mechanical and safety performance of the crane they operate, familiar with and strictly implement the crane operating procedures and safety procedures, skilled in lifting operation skills, must concentrate on the operation, obey the command, careful operation.

 

③ when the operator operates the crane, it must obey the command of the commander, for the emergency stop signal, no matter who issued it should be immediately executed.

 

④ before each use of the crane, the operator must first check the eot crane brake, hook, wire and so on.
