LOW-CONSTRUCTION TROLLEY FOR WIRE ROPE HOIST |
摘要 |
A low-construction trolley for a wire rope hoist is arranged to travel along a lower flange of a horizontal rail, on both longitudinal edges thereof The trolley includes a trolley frame; bearing wheels that are attached to the trolley frame and arranged to travel on an upper surface of the lower flange of the rail; a hoisting mechanism including a rope drum for a hoisting rope, a hoisting member in cooperation with the hoisting rope for hoisting a load, a hoisting motor for driving the rope drum, and a gear to interconnect the hoisting motor and the rope drum; whereby the rope drum is supported to one side of the trolley frame and the hoisting member is arranged to travel under the rail in a vertical plane (A) passing substantially through the middle of the beam. For balancing the trolley without using a counterweight, the hoisting motor is placed under the rail and at least partly on a different side than the rope drum in relation to a vertical plane (B) passing through contact lines of the bearing wheels that touch the lower flange of the rail on the rope drum side. |
