We are one of the largest and most professional crane manufacturers in China, with total sales of more than 1.6 billion US dollars last year, including sales of 11,000 sets of double-beam and gantry cranes, more than 73,000 sets of single-beam cranes, and more than 100,000 sets of electric hoist and accessories.
We have an advanced, green, whole-industry chain, intelligent manufacturing industrial park, with an investment of 370 million US dollars and more than 4,700 employees, which has been established for more than 20 years.
The main parameters of a hoist include the following core elements:
Rated load (rated traction pull)
The rated pulling force refers to the maximum safe pulling force that a winch can bear, usually measured in tons (t) or kilonewtons (kN). For instance, the rated pulling force range of a slow-speed winch is 5 to 500 kN (0.5 to 50 t), while that of a high-speed winch generally does not exceed 200 kN.
This parameter is the core main parameter of the winch and directly determines the working capacity of the equipment.
Rope capacity
It indicates the maximum working length of the steel wire rope that the drum can accommodate, which needs to be verified based on the actual diameter of the steel wire rope. For example, the nominal rope capacity of a certain type of hoist is 200 meters (for Φ19.5mm steel wire rope).
Rated speed
It refers to the speed at which the drum takes up the steel wire rope, with the unit being meters per minute. The rated speed of a slow-speed hoist is usually less than 20 m/min, and the speeds vary significantly among different models (for example, the lifting speed in the example is 9 m/min). Other auxiliary parameters include:
Steel wire rope diameter: It should match the rope capacity and affect the load and durability in actual use.
Power and transmission ratio: Reflect the power configuration (such as 11kW motor with 119.34 transmission ratio).
Control method: Manual or electric control.
Application suggestions: When choosing a winch, the rated load and rope capacity should be matched first, and then the model should be selected based on the working conditions (such as lifting height, speed). For example, slow-speed winches are recommended for lifting and hoisting to ensure safety.
