Single-beam gantry crane is mainly composed of main beam, outrigger, lower crossbeam, running trolley, electric hoist, limit device and control system; the gantry structure has three forms: double cantilever, single cantilever and no cantilever.
Cranes working outdoors are also equipped with wind protection devices such as rail clamps and anchoring devices; the main beam is mostly a skewed box beam structure, and the overall rigidity is weaker than that of double-beam gantry cranes.
      Single-beam hook gantry crane is suitable for Q≤50t, H≤12m, and span S≤35m.

Product features

1. Easy to manufacture and install, good force condition.
2. The weight is small, but the space outside the outrigger for lifting goods is relatively small.
3. Simple manufacturing process.
4. Equipped with emergency stop switch, short circuit protection, pressure loss protection, phase sequence protection and other functions;
5. The three mechanisms of hoisting, trolley and carriage are independently controlled and can operate separately or simultaneously;
6. The trolley limit device can adjust the position according to actual use;
7. The mobile power supply system of the trolley adopts a collection of power supply such as built-in cable pulley, galvanized rail and flat cable;
8. Equipped with overload limiter, upper and lower limit switches;

Applicable occasions
Single main beam gantry crane; the gantry is an L-shaped structure, and the trolley is a winch mechanism; long workpieces can be turned arbitrarily. When loading and unloading long workpieces, the vehicle can be parked at any position, which is mostly used in occasions with small lifting weight and low frequency.
