ZDQ-A-1 series polyurethane buffer detailed parameters

Diameter 80mm, height 96mm
Bottom plate side length 108mm, hole spacing 80mm
Bottom plate thickness 6mm, hole spacing 14mm

ZDQ-A-1 series polyurethane buffer is suitable for elevator rated speed, ≤ 03.63m/allowable mass range (p+Q) kg1500-200
The polyurethane buffer has been proven to be an ideal buffering device after more than 20 years of use. Installed on various mechanical equipment with frequent collisions, it ensures the normal operation of the equipment and reduces equipment and personnel accidents caused by collisions. Ensuring safety.
Working principle of polyurethane buffer: Polyurethane buffer uses the special micro porous bubble structure of polyurethane material to absorb buffering energy, which is equivalent to a spring with multiple airbag damping during the impact process.
Characteristics of polyurethane buffer: light weight, simple installation, no maintenance required, good buffering effect, impact resistance, good compression resistance, good corrosion resistance, no noise or sparks during the buffering process, good explosion-proof performance, safe and reliable, and smooth. Has become the preferred buffer in the crane industry

ZDQ-A-1 series polyurethane buffer usage specification
A、 Regular inspections (at least once every quarter)
B、 It should be avoided to use under low temperature (below -40 ℃) or high temperature (80 ℃) and humidity (85%) environmental conditions:
C、 Should not be used under strong acid or alkali environmental conditions:
D、 The installation and replacement of the buffer should refer to the user manual and icon:
E、 The collision object of the buffer installed on the crane should be aligned with the center of the buffer in the direction of motion, and the end face should be perpendicular. It should not be placed at an angle.
F、 When the buffer configuration is: when the buffer collides with the buffer, buffers of the same diameter should be used, and the longitudinal length of the buffer should be kept as consistent as possible:
G、 When installing the buffer, there should be a certain amount of space around it to avoid accidents such as collision and compression with other components.
H、 The buffer should be stored at room temperature and placed in a ventilated and dry place;
I、 If polyurethane cracks or falls off, it should be replaced in a timely manner.
