Embodiment Construction

[0015] Hoist system 20 is schematically represented at figure 1 middle. System 20 includes an elevator car 22 that selectively moves within a passageway 24 to carry a load between different levels or platforms 26 of a building 28 . Only selected portions of the car support structure within the passageway 24 are schematically shown, and although only one platform 26 is shown, those of ordinary skill in the art will appreciate that the hoist system can often access multiple levels or platforms within the building.

[0016] Building 28 includes a roof surface 30 . The example shown includes a channel roof 32 that extends slightly over most of the roof surface. The invention is also applicable where the channel top 32 is not higher than the roof surface 30 .

[0017] A roof unit 34 is secured to the tunnel roof 32 . The illustrated top unit 34 includes a support base 36 and a cover 38 . The support base 36 is preferably permanently affixed to the roof 30 or tunnel roof 32 . ...

Abstract

A rooftop unit for a machine-roomless elevator includes a selectively removable covery that covers the machine components. In one example, the removable cover is movable relative to the rooftop without requiring removal of the entire over.

Description

technical field [0001] The present invention generally relates to a machine room-less hoist system. More particularly, the present invention relates to a roof mounted unit housing components for operating a hoist system as needed. Background technique [0002] Hoist systems typically include a car guided within a hoistway. Most systems include counterweights associated with the car. Ropes usually connect the car to the counterweight. The drive motor turns the drive pulley to move the rope to cause the desired movement of the hoist car within the tunnel. [0003] Traditionally, hoist systems have required a machine room to house drive motors, drive pulleys, and other operating control components. Such parts are generally collectively referred to as "machines", which is where the name "engine room" comes from. The computer room is usually located at the top of the building. Using a computer room, while effective, is not without its drawbacks. The building construction m...
