Chain type highrise group escaper is composed of the carrying chain and multiple speed reducers. The standard-type can serve for 5 people at one time and the enhanced-type can serve to 8. There are mainly two ways to fix the carrying chain according to the fire situation, including the conventional (Recommended) and unconventional patterns. The speed reducers can be centralized or decentralized stored on each floor. When escape, you only need to put on the body belt and gear the speed reducer to the carrying chain which has already fixed on the roof or some highest point in the building. The speed reducer will send you down to the ground with a steady speed (0.8-1 m/s) without manipulation. Everyone can easily use the fire escaper no matter child, elderly, weak or sick. The product contains a retrievable rope of diameter 15 mm, it is gripped by the people and provides a mental support when people start to leave the window or balcony, it also provides double protection. The rope can be used to retrieve the speed reducers that have been descended to the ground. It can also be used to distribute centralized reducers to other floors for escape.
