FAQ
How to Choose a construction hoist?
When customers select the building equipments, security issues should always be put on the top of the list. Therefore, all the safety devices should be checked before purchasing, such as limit switch, anti-fall device, loading capacity limiter, etc. All these accessories are necessarily prepared by standard suppliers.
In addition, customers should also investigate the company’s history, production scale, reputation, credibility, the ability to take a risk, as well as the efficiency of the after-sales service.
