Description
MH type electric hoist gantry crane is used together with CD MD model electric hoists. It is a track traveling small and medium-sized cranes. Its proper lifting weight is 5 to 20 tons. The proper span is 12 to 30 meters, its proper working temperature is -20°C to 40°C.
Working Condition
1. 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.
2.The whole machine must have relatively high anti-overturning stability.
3.The prime mover has the power to meet other requirements, and the braking device should provide the necessary braking torque.
Features
It is a structural form welded with angle steel or I-beam, with the advantages of low cost, light weight, and good wind resistance.Suitable for sites with low safety requirements and small lifting capacity.
However, due to the large number of welding points and the inherent defects of the truss, the truss beam also has disadvantages such as large deflection, small stiffness, relatively low reliability, and the need for frequent inspection of welding points.
