Manufactured to rigid standards to deliver maximum efficiency
Advantages of crane bumper:
- More economical than alternative bumpers
- Custom engineering and design for non-standard applications
- Manufactured to rigid standards to deliver maximum efficiency
- Long service life - a life cycle that is six times longer than that of other bumpers
- Quiet operation
- No moving parts to fail; as are found in hydraulic or spring bumpers
- Compact and lightweight
- Efficient at most temperatures, from -60° to 225°F (-51° to 107° Centigrade)
- Unaffected by oil, grease, ozone/aging
- Surpass the performance of hydraulic bumpers and bumpers made from rubber, foam material, wood, plastics,
- Compositions, non-ferrous metals and steel
- Offer a much greater cushioning effect than other bumpers
Why to use crane bumper?
- overhead crane bumpers, such as, bridge bumpers and trolley bumpers are required to be used on overhead crane and gantry crane according to OSHA standards. Why to used crane bumpers?
- There are several benefits of using overhead crane bumpers.
- The shock of impact in the normal course of operation and act as an emergency backup will be adsorbed by overhead crane bumpers. However, when a crane with no crane bumpers, it has nothing to absorb the impact of collision. When multiple cranes on a runway collide, end truck to end truck, the damage will be tremendous if there is no crane bumpers.
- While the slow down or stop limits are devices that improve crane safety by reducing or preventing the impact overhead crane bumpers sustain.
- These electrical components, which are activated by a sensor, stop or slow down a crane, preventing the bumpers from coming into contact with the end stops – or at least slowing the crane enough to limit the impact that the bumpers must sustain. Stop limits come standard on Dongqi bridge cranes.
- Bumpers typically are made of rubber, but for larger cranes – 50-ton capacity and up, the crane bumpers used is the hydraulic overhead crane bumpers, which absorbs more shock than rubber crane bumpers.
- Polyurethane bumpers are a relatively new alternative to rubber crane bumpers. They are more durable and longer lasting than rubber bumpers, which tend to dry out and crack over time.
- And, without quarterly or annual crane inspections, rubber overhead crane bumpers may fall off unnoticed, until a collision occurs. Missing crane bumpers can lead to derailments.
- A crane can derail or get jammed in the rails when one side of the crane is without a bumper. This happens because the side that still has a bumper makes contact before the other side, forcing the crane out of alignment between the rails. Forced askew like this, the wheels sustain cracked flanges, which can lead to a derailment if not repaired.
- Overhead crane bumpers for bridges and trolleys are essential components for crane safety because they reduce the risk of damage, derailment, and wear and tear on cranes.
