Four lifting plates are balanced and stable in lifting, with the lifting housing made of high-strength flame-retardant nylon material, suitable for operation in environments ranging from -20°C to 120°C. The teeth are Φ12 steel, and the pipes are galvanized, with an overall compact and sturdy structure.

2. The motor is a DC24V pure copper motor, capable of lifting and lowering up to 20,000 cycles (frequency not exceeding 20%), with noise below 50db, limit switch click life of not less than 50,000 times, high-temperature wire rated to 120°C, all passing a 20kg tensile test. The wire core is 0.75mm² copper wire, supporting currents up to 10A (with the motor's normal operating current at 2A).

3. The control box can receive 433MHz wireless signals up to 100 meters away, with an output power of up to 120W (5A). The product can automatically protect itself and emit a double-beep alarm in case of short-circuit or overload. The control box is equipped with up/down buttons for emergency or maintenance use.
