Abstract

A hand-operated and electric integrated crane comprises a base and an electric cabinet; an electric hoisting mechanism and a hand-operated hoisting mechanism are installed inside the base; a vertical column is fixedly arranged on the upper portion of the base through a fastening piece; an electric swinging mechanism and a hand-operated swinging mechanism are installed inside the vertical column; the electric cabinet is connected with the electric hoisting mechanism and the electric swinging mechanism through leads; the electric cabinet is connected with a power supply through a power supply cable; a suspension arm is welded to one side at the upper end of the vertical column; a hoisting winch is installed at the top of the vertical column; a pulley is arranged at the head of the suspension arm; one end of a steel rope is connected with the hoisting winch; the other end of the steel rope penetrates the pulley; a shackle is connected with a lifting hook. According to the hand-operated and electric integrated crane, cargos are craned through an electric mechanism under an electric power supply condition, a hand-operated mechanism is used for emergency under an electric-power-supply-free condition, and the working efficiency is not influenced.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a hand-electric integrated crane. Background technique [0002] Marine cranes are devices and machinery provided by ships for loading and unloading cargo, mainly including boom devices, deck cranes and other loading and unloading machinery. [0003] Small-tonnage electric cranes in the ship market are mainly used for hoisting food, spare parts, and sundries in fixed areas. Because all actions are electric and require electric power supply, it is relatively fast and convenient; but when the ship cannot supply electric power, electric cranes Crane just can't work, causes can't normally use, affects working efficiency. Contents of the invention [0004] Aiming at the shortcomings in the above-mentioned existing production technology, the applicant provides a hand-electric integrated crane with reasonable structure, so that it can be used flexibly and conveniently, and w...
