Embodiments of the present disclosure describe methods and apparatuses for a load lifting system.

A carrier building ladder hoist that contains a removable carrier casing and a winch casing allowing a user to hoist items. The ladder hoist contains a padded back and straps to allow an individual to carry it on their back and wheels and a tow handle to allow the user to tow it behind them. The side surfaces of the winch casing in ladder hoist have grooves in them to allow a user to hook the ladder hoist to a ladder. The ladder hoist has a winch system using gears and a winch strap ending in a hook.

A fork for an industrial vehicle such as a forklift, and a method of making the same. The fork includes an elongate body portion, a toe portion, and, optionally, a heel portion. The elongate body portion may be formed in any length and coupled to the toe portion (and optionally, to the heel portion) to form a fork.

The present invention provides a hoisting device for working in heights, specifically including a vehicle body, a lower bracket installed at a bottom of a safety ladder, a host driver fixed on the lower bracket and providing lifting power, an upper bracket installed at a top of the safety ladder, a traction rope connecting the upper bracket, the vehicle body and the host driver, and a sliding rail installed on the safety ladder, and further including a fall arrester installed on the sliding rail, a guiding device assembly installed on a back portion of the vehicle body, a stall protection device installed on the vehicle body and matched with the sliding rail, a collapsible pedal installed on a lower portion of the vehicle body and configured to carry people and goods, an operation handle fixed to an upper portion of the vehicle body and a position-limiting bracket installed on an upper portion of the safety ladder. The host driver drives, trough the traction rope, the vehicle body to ascend or descend along the sliding rail, thus enabling the vehicle body to ascend or descend so as to convey people and goods. The hoisting device is simple and convenient to operate, occupies a small floor space and can be installed without changing a structure of an original safety ladder.

Rescue elevator system, comprising a rescue ladder and an elevator running on rails on a top side of the rescue ladder up to an end position at one end of the rescue ladder, and an elevator drive comprising a rope, a rope winch for pulling the rope and a deflection roller over which the rope is guided from the rope winch to a suspension point at the elevator, wherein the deflection roller is disposed below the rails at or near the one end of the rescue ladder, characterized in that the suspension point is displaced towards a trailing end of the elevator averted from the one end of the rescue ladder such that in the end position of the elevator, the suspension point is located in a distance from the deflection roller in the extension direction of the rails, and the elevator comprises a passage ladder to bridge the distance between the suspension point and the deflection roller in the end position of the elevator, said passage ladder lying on top of the rope and being mounted between the rails at a hinge axis perpendicular to the extension direction of the rails and extending generally towards the one end of the rescue ladder such as to be pivotable between a flat position in which it lies generally parallel to the plane of the rails and an inclined position in which it is inclined downwardly towards the bottom side of the rescue ladder.
