A remote controlled lift assembly includes a pair of supports is each mountable to a respective outrigger of scaffolding. A winch unit is positionable on the supports when the supports are mounted on the scaffolding and the winch unit has a cable extending downwardly therefrom. The cable is lowered or lifted when the winch is actuated. A receiver is coupled to the winch unit and the receiver is in electrical communication with the winch unit. A remote control is provided that is carried by a user and the remote control is in wireless electrical communication with the receiver. In this way the user can remotely lift and lower the cable for lifting and lowering cargo.

A hoisting assembly for lifting a load into an attic or lowering a load therefrom includes a hoist. The hoist comprises a housing, which has a drum or a lift wheel engaged thereto and positioned in an interior space defined thereby. A suspension module is engaged to and extends from an upper end of the housing. The suspension module can selectively engage a beam so that the housing is suspended from and removably engaged to the beam. A lifting medium is operationally engaged to the drum or the lift wheel and extends from a lower end of the housing. A connector is engaged to the lifting medium distal from the housing. The connector can selectively engage a load so that the load is removably engaged to the lifting medium. The hoist thus is configured to lift the load.

A support arrangement for a fluid monitoring system is provided, configured for being secured within a vertical shaft and for facilitating positioning of a fluid monitor suspended therefrom. The support arrangement includes an attachment arrangement to be secured to a vertical access shaft of an open channel fluid transport system, a cross rail assembly including a cross rail and being configured to be mounted to the attachment arrangement for being supported thereby, and a lifting assembly mounted on the cross rail and configured for suspension therefrom of the fluid monitor along a vertically-extending suspension axis. The cross rail is configured to be rotatable about a vertical axis when at least partially received within the attachment arrangement. The lifting assembly is configured to be selectively secured to one of a plurality of lateral positions along the length of the cross rail.

An adjustable standoff for a platform hoist that can withstand hoisting objects along a track to a predetermined height weighing up to 500 pounds. The adjustable standoff for a platform hoist includes: (1) a frame having two side assemblies with hooks to attach the standoff to only the rungs and thereby avoid blocking the side rails that act as the track for the hoist; (2) two legs that are able to adjusted radially within the plane of the side assemblies so that the standoff can withstand the force exerted by loads weighing 500 pounds being hoisted up; and (3) an anchor section to securely fasten the hoist to the structure to avoid the hoist sliding down the ridge of the roof and allowing the heavy loads to crash to the ground with potentially catastrophic consequences for both the structure and the operators below.

Simultaneously oppositely rotating sheaves, or a chain fall, has a two sheaves upon a hexagonal axle. The first sheave receives a first line clockwise and the second sheave receives a second line counterclockwise. Upon turning the axle, the sheaves handle the lines oppositely. A signal unit regulates power delivered from a power unit to at least one motor. The power unit is preferably a battery or alternatively another source. The motor turns a gearbox that engages the axle cooperating with the sheaves. The chain fall includes an anti-two block per line. Preferably, a pulley has two outer plates and two inner plates on stubs with the first line in the center and the two second lines between an inner plate and an outer plate. A first plate and a spaced away second plate contain the components of the invention in compact form for usage by a crane.
