Product Description

Brief Introduction: 

This QDY double girder Metallurgy Bridge Crane is mainly used in the place where the molten metal is lifted. The working duty of the complete machine is A7, and thermal protective device is added on the bottom of the main girder.

The assembling and test of the crane conform to the document No.ZJBT[2007]375 which was issued by General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China.

It can be also used in the place where molten nonmetal material and red-hot solid metal lifting work.
Environmental conditions:

Power supply: 380V/50HZ/3PHASE or on request.
The temperature of working environment is -10~+60°C;
The relative humidity is less than 50%
Advantages of a Double Girder Design
1.Greater hook height - how far above the floor the hoist will lift (typically 18-36" more than single girder)

2.No limits to maximum span or capacity

3.Ideal for production and transportation of heavy equipment

4.Ideal for frequent lifting of heavy loads

5.Added features like walkways and maintenance platforms, cabs, magnetic reels, and lights can be added and supported by a double girder design
Can be used in indoor and outdoor applications, including mining, iron and steel, railyards, and ports

Safe Devices:
1.Overload Limit Switch

2. Rubber Buffers 3.Electric Protective Devices

4.Emergency Stop System

5.Voltage Lower Protection Function

6. Current Overload Protection System

7. Rail Anchoring 8.Lifting Height Limit Device
