Abstract

The invention discloses a low-clearance hand power truck crane which comprises a crane body, two sets of running drive mechanisms, a hoisting drive mechanism and a lifting hook mechanism. The low-clearance hand power truck crane is compact in overall structure; when a lifting hook ascends to the highest position, the distance between the center of the lifting hook and the bottom of an I beam is only 450 mm; the maximum lifting height of cargoes becomes large; the hoisting transportation requirement under the low-clearance working condition is met; the cargoes can be lifted by a chain block main machine at any end of the crane body, and meanwhile the lifting speed is higher; the two sets of running drive mechanisms are distributed in a balanced manner; the crane is driven through engagementtransmission of driven gears and racks at the bottom of the I beam to run; running stability is good; and operation safety is high.

Description

technical field [0001] The invention relates to the field of hoisting equipment, in particular to a hand-drawn trolley with low headroom. Background technique [0002] The structure of the existing hand-pulled crane for lifting and transportation is not compact, and the overall vertical height is long, which affects the lifting height of the goods. It cannot meet the lifting requirements of the goods in low buildings or working conditions with small clearance limits. , and the walking stability of the transported goods is poor. When there is shaking in the external environment (such as the cabin, etc.), it is easy to cause the walking trolley to deflect and fall, and the operation safety is poor. Contents of the invention [0003] The object of the present invention is to provide a low clearance hand-drawn trolley to solve the problems that the existing hand-drawn trolley for lifting and transportation cannot meet the needs of lifting and transporting goods in low-clearanc...
