Single beam gantry crane
The single main beam gantry crane is mainly composed of main beam, leg, lower beam, running trolley, electric hoist, limiting device and control system, etc. There are three types of gantry structure: double cantilever, single cantilever and no cantilever.
The outdoor crane is also equipped with a rail clamp, anchoring device and other windproof devices; The main beam is mostly off-track box beam structure, compared with double main beam gantry crane, the overall stiffness is weaker.
Single main beam hook gantry crane is suitable for Q≤50t, H≤12m, span S≤35m, can be used in this form.

Product characteristics
1, easy to manufacture and install, good force.
2, its own weight is small, but the space outside the lifting of goods through the leg is relatively small.
3, the production process is simple.
4, configure emergency stop switch, short circuit protection, voltage loss protection, phase sequence protection and other functions;
5, lifting, car, car three independent control, can run alone or at the same time;
6, car limit device, can adjust the position according to actual use;
7, the car mobile power supply system uses built-in cable block, galvanized track and flat cable collection power supply;
8, equipped with overload limiter, upper and lower limit switch;

Applicable occasion
Single main beam gantry crane; The door frame is L-shaped structure, and the trolley is hoist structure. Long workpiece can be turned arbitrarily. When loading and unloading long workpieces, the vehicle can be parked in any position, which is mostly used for occasions with small weight and low frequency.
