Description

A sports car with remote control double braking cable crane

technical field

The invention belongs to the technical field of cable cranes, and in particular relates to a remote-controlled dual-brake cable crane sports car. the

Background technique

Cable cranes are widely used in cargo handling operations in mines, docks, freight yards, etc., and are also used in logging operations in forestry logging areas. The sports car is an important equipment used by the cable crane for lifting and transporting materials, and its function determines the mobility and work efficiency of the cable crane. At present, the sports cars used in general cable cranes are non-intelligent sports cars, that is, the sports cars do not have the function of autonomous braking of the load-bearing cables and hoisting cables. Therefore, most of the general cable cranes use a three-cable cable system with separate load cables, hoisting cables, and traction cables, which not only complicates the power winch system and cable system of the cable crane, but also adds trouble to the installation of the cables. , especially for the skidding operation of the forest skidding cable crane that needs to frequently transfer the operation area, which restricts the application of the cable crane in forest harvesting production to a certain extent. the
