Abstract

The invention discloses a direct current electric hoist which consists of an upper chassis (21) and a lower chassis (1), wherein a slewing mechanism is arranged between the upper chassis (21) and the lower chassis (1); the upper chassis (21) is provided with a power supply as well as a fixed upright (4) and a rotary upright (5) which are in rotary connection; the side surfaces of the fixed upright (4) and the rotary upright (5) are provided with a rotation pushing device; the top of the rotary upright (5) is provided with a main hoisting arm (6); a main pushing device is arranged between the side surface of the rotary upright (5) and the main hoisting arm (6); one end of the main hoisting arm (6) is in rotary connection with the top of the rotary upright (5); a forward-moving hoisting arm (7) is arranged in a chute arranged on the side surface of the main hoisting arm (6); the upper part of the forward-moving hoisting arm (7) is provided with a forward-moving pushing device; and the head of the forward-moving hoisting arm (7) is provided with a hoisting hook (8). The direct current electric hoist disclosed by the invention is compact in structure and can be used for hoisting heavy loads in a narrow space; and the slewing mechanism can ensure the simple and reliable connection between the upper chassis and the lower chassis.

Description

technical field [0001] The invention relates to a DC electric crane. Background technique [0002] Crane is a kind of equipment widely used in all walks of life to transport heavy goods vertically and horizontally. However, larger cranes sometimes cannot meet the lifting requirements in small spaces. And small lifting equipment, though can be practical, has the defective of poor maneuverability. Contents of the invention [0003] The invention provides a DC electric crane, which has a compact structure, can be used for hoisting heavy objects in a narrow space, and has good maneuverability. [0004] The present invention adopts the following technical solutions: a DC electric crane, which includes an upper chassis and a lower chassis, a driving wheel and a driven wheel are arranged on the lower chassis, and a slewing mechanism is arranged between the upper chassis and the lower chassis; The chassis is equipped with a power supply, a fixed column and a rotating column. Th...
