Shenzhen Special Equipment Testing Institute: 98470 Joule elevator buffer drop hammer impact testing machine project

The equipment fully meets the standard requirements of GB7588-2003 "Elevator Manufacturing and Installation Safety Code" Appendix F5 and "Elevator type Test Rules"。

Under the requirement that the ambient temperature of the nonlinear buffer test is 15℃-25℃, the system acceleration should be vertically oriented to the test hammer to ensure that the instantaneous acceleration of the impact buffer reaches at least 0.95gn or more;At the same time, the lifting device has reliable performance, high strength and sufficient safety factor, which can accurately control the falling height of the test hammer, and the control accuracy is ≤ ±1mm。

Personal safety and equipment safety configuration is complete, the decoupling device has a mechanical self-locking device, grasp the test hammer that is self-locking, under the action of gravity will not occur decoupling, another decouple function to prevent accidental power failure, before decoupling set artificial cancel the mechanical protection device steps to ensure safety protection。

In the case of imported elevator unified China's high-end market, the special inspection system for the first time uses the domestic shock absorber drop hammer impact testing machine, marking that China's shock absorber drop hammer impact testing machine has been standing at the same level with imported products, and will contribute to the upgrading of China's elevator industry。
