Abstract

The invention relates to the technical field of lifting appliances, in particular to a balance lifting appliance device. The adopted technical scheme is as follows: the balance lifting appliance device comprises a sling tray for connecting hoisting equipment, wherein at least two groups of sling assemblies are arranged below the sling tray; the sling assemblies comprise connecting bodies connectedwith the sling tray, and the connecting bodies are rotatably connected with a mandrel; the mandrel is used for winding flexible slings, and one end of the mandrel is connected with a torque sensor; and the connecting bodies are also provided with stopping mechanisms, and the stopping mechanisms are used for controlling the rotation of the mandrel. A single rigging has the advantages that the length is adjustable and the stress state is controllable, the scene adaptability and the hoisting safety of the lifting appliance can be greatly improved, the configuration specification and the number of lifting appliances in different application occasions can be reduced, and the guarantee condition of hoisting work is reduced.

Description

technical field [0001] The invention relates to the technical field of slings, in particular to a balanced sling device. Background technique [0002] In the field of industrial production, spreaders are widely used. The existing spreader is a structure with a fixed length of the sling. For different space heights (or equipment heights) environments, it is often necessary to be equipped with spreaders of various lengths and specifications, resulting in complicated management and guarantee. Moreover, when a multi-leg sling is used, since the length of the sling for each leg is basically the same, if the position of the lifting point is unbalanced or the height is not equal, it will cause the posture of the hoisted product to tilt or the force of the sling for each leg to be unbalanced. This may cause the product parts to slip, and there is a risk of equipment damage, or the sling exercise may occur due to excessive force on the single limb sling, which poses a great safety h...
