The Hebei Kaicheng PK two-speed electric chain hoist is a compact and lightweight lifting solution designed for efficiency and reliability. Built with high-strength light metal alloy, this hoist offers both single and double-speed lifting options, making it suitable for a wide range of applications. With a standard lifting height of 3 meters, it can handle loads ranging from 125 kg to 2000 kg, and operates on either 220V or 380V power supply.
The PK two-speed hoist features a three-stage fixed-axis helical gear reducer, ensuring smooth and powerful operation. The gears and gear shafts are made from high-temperature treated alloy steel, providing durability and long service life. The housing and cover are constructed from high-density cast iron, offering excellent structural stability and protection against wear and tear.
All components are assembled in a rational and secure manner, with excellent sealing performance. The modular design of the reducer makes maintenance and disassembly easy, reducing downtime and improving overall efficiency. During operation, the hoist maintains a stable center of gravity, ensuring safe and efficient lifting. It can be used in fixed suspension setups or combined with a trolley on single-beam or double-beam cranes, offering versatile application possibilities.
In terms of electrical control, the two-speed electric hoist comes in two types: direct control and contactor-controlled. The direct control system allows users to operate the motor’s forward, reverse, and fast speed functions directly using a flashlight switch. The contactor-controlled version uses a control transformer to manage the motor’s movement, offering more precise and safer operation.
The flashlight door is designed for user safety, featuring either a single-speed or dual-speed button depending on the model. A single-button flashlight is used for single-speed hoists, while a dual-button model is used for two-speed hoists. When the first gear is pressed, the motor runs at a slow speed, and when the second gear is engaged, it switches to high speed. A red emergency stop button, marked with a clockwise arrow, allows immediate power cutoff in case of emergencies or after use.
When the flashlight door is operated, the button must be turned clockwise. Once released, the button resets automatically, activating the manual switch and powering up the hoist. This ensures a controlled and safe start-up process.
