Building construction crane

Abstract

The invention relates to the technical field of craning machinery, and specifically relates to a building construction crane. The building construction crane comprises a base, wherein a traction structure is installed on the base; a telescopic structure is arranged in the traction structure; a hoisting structure is arranged at the end part of the traction structure; the hoisting structure is connected with a hanger structure; a winding structure is arranged between the hanger structure and the hoisting structure; a counterweight structure is arranged in the base; and a locating structure is arranged between the counterweight structure and the base. An object can be dragged and lifted through the traction structure, a cable is prevented from being separated, the lifted object can be conveniently taken down through the telescopic structure, a clamping distance can be adjusted as needed through the hoisting structure, scattered plates can be conveniently bound and fixed through the hanger structure, and the stability in the lifting process is ensured; and the releasing length of a steel rope can be controlled through the winding structure, arrangement for a counterweight can be properly adjusted through the counterweight structure, fixing for the position of the counterweight can be ensured through the locating structure, and the stability is ensured.

Description

technical field [0001] The invention relates to the technical field of hoisting machinery, in particular to a building construction crane. Background technique [0002] A crane refers to a multi-action hoisting machine that lifts vertically and carries heavy objects horizontally within a certain range. Cranes are widely used in daily life. In the field of construction, it is usually necessary to use a variety of lifting machinery of different specifications, from bulky tower cranes, that is, tower cranes, to smaller mast-type lifting equipment, lifting equipment The application of it greatly facilitates the transportation of building materials. [0003] However, small-scale lifting equipment is usually used for small-scale transportation of a small amount of building materials. When traditional lifting equipment of this type is used, if there is a protruding part below the floor where the equipment is arranged, it will be difficult to remove the lifting objects. At the s...

Problems solved by technology

[0003] However, small-scale lifting equipment is usually used for small-scale transportation of a small amount of building materials. When traditional lifting equipment of this type is used, if there is a protruding part below the floor where the equipment is arranged, it will be difficult to remove the lifting objects. At the same time, due to the limitation of a single sling, if the cement slurry is hoisted, multiple buckets of mortar are hoisted at the same time, and there will be a situation of pouring, and when hoisting long plates, etc., it is necessary to use ropes Bundling is performed in advance, and instability may still occur even in the case of bundling. On the other hand, the placement of counterweights for balancing equipment cannot be changed according to the specific placement environment
