Introduction to the Key Features of Construction Hoists

The structure is stable: being an H-shaped frame, the hoist cage operates within the well frame, and the wall attachment is reasonable and reliable, thus ensuring the frame's solid and stable performance.

2. Smooth Elevator Operation: The elevator operates smoothly due to the use of traction machine friction drive, featuring four steel cables for traction and equipped with counterweight balance. This results in minimal speed difference and low noise during the up and down movement, as well as smooth starting and stopping.

3. Safety and Reliability: With the use of four 6×19-9.3-1670 steel wire ropes for traction, each rope is capable of independently supporting the weight of the hoist cage and its load, making the likelihood of all four ropes breaking simultaneously and causing a fall extremely low, nearly negligible. The traction machine is equipped with two brakes that can safely stop 1.25 times the rated load, ensuring reliable braking. The hoist cage does not exhibit any slipping when stopping at floors.

4. Non-Climbing Design: Driven by the frictional transmission principle, the parallel four steel wire ropes ensure that the hoist cage and counterweight operate independently on their respective tracks, preventing any possibility of the hoist cage or counterweight from colliding with the ceiling.

5. Automatic Fall Prevention: Equipped with an automatic fall prevention device, which engages when the hoist cage encounters a sudden break in the traction steel wire rope during upward or downward movement. In the event of the cage losing weight and free-falling, the automatic fall prevention device, under the force of springs, acts on the eccentric clamping wheel to securely grip the guide rail, effectively stopping the cage. It boasts rapid braking, no impact, and reliable safety, ensuring the equipment remains undamaged.
