BMH Model Single beam semi gantry crane is based on the MH type single girder gantry crane,

One side is gantry crane design and another side is overhead crane design.

It takes use of the Wall steel structure beams so could efficient to save the total cost of crane.

BMH model semi gantry crane is widely used with wire rope electric hoist, the lifting speed could be one speed or two speed; this semi gantry crane is a middle and small duty crane, could be controlled by ground control and remote control. 

Crane Configuration: 

Material:  Steel plate material Q235 or Q345B ( similar international steel plate FE3 or FE52)
Steel structure: Strong Steel box type, seamless type, more strong and elegant beam.

Crane traveling motor: Soft start type
Wheel:Vacuum casting by our group, Inter medium frequency quenching

Main electrical parts: Schneider brand or Siemens brand.

1. Limit Switch: Safety limit switches for stoppers prevent over traveling in all motions.

2. Anti collision device

   When two crane traveling on the same rail, the cranes will install the following devices:

   Anti-collision device, Infrared non-contact and inductive type limit device

   Sound and light alarm device, Wireless anti-collision device

3. Weight overload protection device

   Includes automatic stopping type lifting weight limiter and weight display device.

4. Lifting limit switch and traveling limit switch

5. Emergency stop system

6. Electrical protection

   The main insulation switch, emergency stop switch, short circuit, Zero voltage protection,  loss of field               protection, Current overload protection, over speed protection, zero position protection

    Phase sequence protection and adopted crane specially anti- vibration contactor etc.

7. Interlock device

   It sets interlock device for the cabin door and the other door from cabin into bridge structure, when the door    is opened, the crane cannot work.
