Abstract: A lifting beam for lifting a load. The lifting beam comprises: an elongated beam; a load balancing mechanism movably associated with the elongated beam and having a horizontal arm and a counterweight attachment element, from which a counterweight can be hung; a lifting ring connected to the elongated beam from which the lifting beam can be hung; and a load attachment mechanism whereby the load is attachable to the lifting beam, wherein the load balancing mechanism further comprises a counterweight movement apparatus adapted to move the counterweight along the elongated beam in order to help balance the load, and the elongated beam has a series of micro-switches along a bottom surface thereof the micro-switches arranged whereby an end of the horizontal arm will contact one of the switches in the case of undue tilting of the lifting beam.

Abstract: A hoist for construction sites, for carrying loads suspended from a crane. The hoist is C shaped, suspended at its top arm by a cable of a crane. The bottom arm carries a hook, typically vertically movable, for lifting and moving loads about in the construction site. Owing to its lateral opening, the hoist can deliver loads into the interior space of floors, using minimal crew and relying mainly on the crane for maneuverability.

Abstract: A suspended concrete bucket for dispensing concrete in building sites. A shutter is disposed at the at the cement releasing aperture of the bucket. The shutter is horizontally slidable, controlled by a handle. Opening of the aperture is controlled by an operator sliding the shutter on wheels. The released cement flows through the opened aperture into a hose, for pouring into forms.
