Description
BMH Type Semi Gantry Crane is a bridge-type crane whose bridge is supported on the ground track through outriggers on both sides. Structurally, it consists of a mast, a trolley operating mechanism, a lifting trolley and electrical parts. Some gantry cranes only have outriggers on one side, and the other side is supported on a factory building or trestle, which is called a semi-gantry crane.
Working Condition
- Metal structures and mechanical parts should have sufficient strength, stiffness and buckling resistance.
First of all, it is required that parts and metal structures are not damaged after being loaded. For parts such as steel wire ropes with complex stress states, static strength calculations are usually performed with a higher safety factor based on the main load and main deformation form. It must also be required that the deformation of the component under load is within the allowable range, that is, it should have sufficient stiffness. - The whole machine must have relatively high anti-overturning stability.
- The prime mover has the power to meet other requirements, and the braking device should provide the necessary braking torque.
Features
FEATURE 1
Half door design: The bottom only has a half door structure, and the top does not have a door structure, so the structure is relatively simple, easy to install, and maintenance costs are low.
FEATURE 2
Flexible movement: The walking mechanism adopts dual wheel drive, with a small turning radius, and can move freely in narrow areas.
FEATURE 2
Large lifting height: The lifting height is large and can meet the needs of high-altitude operations.
FEATURE 4
Easy to operate: The control system adopts electrical control, which is simple and convenient to operate, and has remote control function.
FEATURE 5
Safe and reliable: equipped with multiple safety protection measures, such as overload protection, displacement protection, limit protection, etc.

Spare Parts
Main beam
The main beam is a box beam or H-beam structure, welded and formed from steel plates. The steel plate material is domestic steel (Q235B). The vertical winding is in accordance with Chinese national standards. All steel plates are subjected to shot blasting pre-treatment to achieve Sa2.5 level standardization. Before welding, the steel plates are carefully inspected and cleaned, usually by automatic welding machines (MIG or semi-automatic welding).
Ground beam
The lower beam is also a box-shaped structure, mainly composed of cover plates, webs, ribs, flange supports and other parts. The production process is similar to that of the main beam and other box beams. After the lower beam structure is completed, the bent plates are assembled according to the drawing. The flange support is welded to the lower beam after the lower beam is made to ensure the level of the flange surface. When the lower beam and the leg are assembled, the flange on the flange made on the leg is welded to the leg. The appearance quality and geometric dimensions of the lower crossbeam after production meet the requirements of the standard GB14406-93.
Electric hoist
The lifting capacity of electric hoists is generally 0.3-80 tons, and the lifting height is 3-30 meters. Composed of an electric motor, transmission mechanism, and a drum or sprocket, it is divided into two types: wire rope electric hoist and ring chain electric hoist. The electric chain hoist is divided into two types: imported and domestically produced; The wire rope electric hoist is divided into single speed lifting and double speed lifting; small electric hoist, multifunctional hoist.
Crane remote control
Industrial wireless remote control is a remote wireless remote control device specifically used to control construction machinery or industrial equipment.
Crane control box
The surface of the control box has undergone anti-corrosion treatment Reasonable layout for easy maintenance Protection level IP55 Environmental temperature:<45 ° C, humidity<90%.
