Abstract

The invention discloses a construction hoist with an underneath type traction machine suitable for a building hoistway. The construction hoist comprises the traction machine, a sky beam, a traction medium, a cage and a counterweight. The sky beam is transversely arranged at the upper end of the building hoistway, the traction machine is arranged at the bottom of the hoistway, and a rewinding wheelis arranged above the traction machine. A first pulley is arranged at the top of the cage; a second pulley and a third pulley are arranged at the upper end of the sky beam at intervals; a fourth pulley is arranged on the counterweight; one end of the traction medium is led out upwards from the traction machine, bypasses the second pulley and the first pulley and then is led upwards and fixed; theother end of the traction medium is led out upwards from the traction machine, bypasses the rewinding wheel and the third pulley and then is led downwards to the fourth pulley, and the traction medium bypasses the fourth pulley and then is led out upwards and fixed; and the hoist has the advantages of being high in safety, convenient to maintain and low in noise.

Description

technical field

[0001] The invention relates to the field of building construction hoists, in particular to a traction machine under-mounted construction hoist suitable for building shafts. Background technique

[0002] Construction elevators are also called construction elevators. Conventional construction elevators are construction machinery that uses gears, racks, etc. to make the cage move up and down to transport construction personnel, tools, equipment and materials. There are disadvantages of low efficiency and high noise, and the traditional elevator is installed on the outer wall of a high-rise building with low safety.

[0003] To this end, we have developed a traction machine under-mounted construction hoist suitable for building shafts. SUMMARY OF THE INVENTION

[0004] The purpose of the present invention is to provide a traction machine under-mounted construction hoist suitable for building shafts in order to overcome the deficiencies of the prior art. [0...
