Why do crane equipment use bumpers

Advantages of crane bumper:
1. Customized engineering and design for non-standard applications;
2. Manufacture according to strict standards to provide efficiency;
3. Long service life - life cycle is six times longer than other bumpers;
4. Quiet operation;
5. No moving parts failed; As seen in hydraulic or spring bumpers;
Compact and lightweight; 6.
7. In the 60 ° to 225 ° F (- 51 ° to 107 ° C) the temperature range of high efficiency;
8. Free from oil, grease, ozone/aging;
9. Performance beyond hydraulic bumpers and bumpers made of rubber, foam, wood and plastic
10. Composition, non-ferrous metals and steel;
11. Provides greater cushioning effect than other bumpers. Why use crane bumpers?
According to OSHA standards, overhead crane bumpers, such as bridge bumpers and trolley bumpers, need to be used for bridge and gantry cranes. Why use crane bumpers?
There are several advantages to using overhead crane bumpers.
The impact shock during normal operation and as an emergency reserve will be absorbed by the overhead crane bumper. However, when a crane does not have a crane bumper, it does not have any absorption impact. When multiple cranes on the runway collide, terminating the truck to the terminal truck, the damage would be huge if there were no crane bumpers.
Deceleration or stop limit is a device that increases crane safety by reducing or preventing the impact on the overhead crane bumpers.
These electronic elements, activated by the sensor, can stop or slow the crane, prevent the bumper from contacting the end stop - or at least slow the crane enough to limit the impact that the bumper has to bear. East bridge crane standard restrictions.
The bumpers are usually made of rubber, but for large cranes - with a capacity of 50 tons or more - the crane bumpers used are hydraulic overhead crane bumpers, which absorb more impact than the rubber crane bumpers.
Polyurethane bumper is a relatively new substitute for rubber crane bumper. They are more durable and durable than rubber buffers, which tend to dry and break over time.
And if the crane is not inspected quarterly or annually, the rubber overhead crane bumpers may be ignored until a collision occurs. Missing crane bumpers can lead to derailment.
When there is no bumper on one side of the crane, the crane can derail or get stuck in the guide. This happens because there is still a bumper on one side that contacts before the other, forcing the crane to misalign between the rails. As such, the wheel is forced to tilt and the flange is cracked. Failure to repair it will cause derailment.
Overhead crane bumpers for Bridges and trolleys are an important part of crane safety as they reduce the risk of crane damage, derailment and wear.
