1. The gantry crane has a portal frame structure with two supporting legs under the main bearing girder, and the cart can walk on the ground pre-laid track. It has the characteristics of high site utilization rate, wide operation scope, wide adaptability and strong versatility, so it can be widely used in outdoor freight yard, stock ground and the loading and unloading operation of bulk cargo.
2. MH electric hoist gantry crane is used in conjunction with CD1 and MD1 type electric hoists. The electric hoist is suspended on the lower edge of main girder or I-beam main girder. Its lifting weight is 1t-6t, span is 7.5-28.5m, working level is A3-A4, and temperature of working environment is -25℃ ~40℃.
3.MH electric hoist gantry crane has two operation modes: ground operation and control room operation. Ground operation usually adopts the operation mode of handle button + remote control; the operation room includes open type and closed type, which can be divided into left and right installation according to the circumstance.
4.MH electric hoist gantry crane usually uses conical brake motor as lifting and operation, and gear reduced drive as reduction gear; the whole equipment is equipped with lifting, descending limit switch, cart travel switch, handle button, overload limiter and other accessories.
5. MH electric hoist gantry crane is forbidden to use it in flammable, explosive and corrosive medium environment.
6. The main beam of MH electric hoist gantry crane can be overhung in one direction or in two directions. The main girder structure has truss structure and box girder structure, and the construction cost can be greatly reduced by choosing the appropriate main girder structure through the reasonable design of the main girder structure.
