The advantages of CD type trolley integrated electric wire rope hoist are small length and size, and the electric hoist with the motor installed in the drum.
The electric hoist has a compact structure. The electric hoist whose motor axis is perpendicular to the drum axis adopts worm gear transmission device. Its disadvantages are: large size in length, large size in width, bulky structure, low mechanical efficiency, and difficult processing. The hydraulic system is under dual control. The pressure can be controlled by the overflow regulating valve and magnetic contact pressure gauge. The electrical control department has adopted low voltage control, which increases the safety of the control system. No manufacturer has produced products of this structure.
Structure and features: the machine adopts the mechatronic design, and can press steel wire ropes of different specifications by changing different molds, which is simple and safe to control. Its main disadvantages are poor heat dissipation premise of the motor, poor grouping, convenient inspection, installation and maintenance of the motor, and complex power supply device. The electric hoist whose electric drive axis is parallel to the drum axis has the advantages of small height and length. Its disadvantages are large width, poor grouping, and complex manufacturing and assembly.
Classification and description of CD type trolley integrated electric wire rope hoist The components of the wire rope electric hoist are: motor, transmission mechanism, drum and sprocket. According to the different positions between the motor and the drum, it can be roughly divided into four types. The pressed steel wire rope has a large pull force, beautiful appearance and fast speed. It only takes a few minutes to crimp a set of steel wire rope, which greatly reduces labor intensity and improves work efficiency.
The electric hoist with the motor installed outside the drum has the advantages of good grouping, high generalization, easy change of lifting height and convenient device inspection.
