Abstract
Traction sheave elevator comprising a drive machine (10), a traction sheave (7) connected to the drive machine, two diverting pulleys (5,6), an elevator car (1), a counterweight (2) and a hoisting rope rigging (3) on which rigging the elevator car and its counterweight are suspended. Each deflection of a hoisting rope in the rigging (3) takes place along a circular path determined by a rope groove on the traction sheave (7) or a diverting pulley (5 and 6), occurs in essentially the same direction with respect to the direction of the shafts of the traction sheave and diverting pulleys.
Claims8
Traction sheave elevator comprising a drive machine, a traction sheave provided with rope grooves and connected to the drive machine via a shaft, at least two diverting pulleys provided with rope grooves and each diverting pulley being rotatable about a shaft, an elevator car travelling along elevator guide rails, a counterweight travelling along counterweight guide rails and a hoisting rope rigging having at least one hoisting rope, on which rigging the elevator car and the counterweight are suspended and which rigging is so arranged that it passes via a wheelwork having the traction sheave and diverting pulleys and runs crosswise relative to itself, each deflection of each hoisting rope in the rigging takes place along a generally circular path determined by a rope groove in the traction sheave or a diverting pulley and occurs in essentially the same direction with respect to the direction of the shafts of the traction sheave and diverting pulleys, each rope in the rigging runs in a rope groove on the traction sheave so that there is a continuous contact angle on the traction sheave between 200-270 degrees.
