Single-beam suspended track type electric hoist

The utility model relates to a track electric hoist of a single-beam suspended type, belonging to the technical field of cranes and hoists. The utility model is composed of two linkage carts and the orbit beams thereof, a fixed orbit beam and a track mechanism, wherein, both the two linkage carts and the fixed orbit beam adopt a single-beam structure. The utility model has the advantages of simple structure and low requirements for technology. Four joints which are butted in two pairs by H-shaped beams are reduced to two joints; in addition, the track mechanism adopts the structure of double pendulum cams, so that an electric hoist which can track safely only by opening a movable spacing plate can not slidedown automatically. The utility model plays a safe role, and is ideal special equipment for lifting.
