The mechanism runs along the lower flange of the I-beam of the main beam when working. The gantry structure is divided into two types: box-shaped and truss. The box-shaped technology is good and easy to manufacture; the truss has light weight and strong wind resistance. The whole machine has the characteristics of light weight, simple structure, convenient installation and maintenance, etc. It is suitable for outdoor places such as factories and mines, freight yards and warehouses within the range of small and medium lifting weights for general loading and unloading.
MH type electric hoist gantry crane (truss type) is used in conjunction with CD, MD and other types of electric hoists. It is a small and medium-sized crane that runs on rails. The main girder and outriggers are welded into a truss structure with steel. The light weight of the frame structure is beneficial to reduce the impact of wind on the crane.
The truss gantry crane uses angle steel or I-beam welded structure, which has the advantages of low cost, light weight and good wind resistance. However, due to the many welding points and the defects of the truss itself, the truss beam also has the disadvantages of large deflection, low rigidity, relatively low reliability, and frequent inspection of the welding points. It is suitable for sites with low safety requirements and small lifting weight.
There are three operation modes: ground handle, wireless remote control and driver’s cab.
There are two forms of power supply: cable reel and high-altitude sliding line.
MH type electric hoist gantry (truss) crane is a general purpose crane, which is mostly used for loading and unloading or grabbing materials in open places and warehouses. This product has two types of ground operation and indoor operation. It is suitable for lifting weight of 3-20T, and suitable for the span of 12-30 meters. Working environment -20°C- +40C.
