Necessity of installation and protection of roof fixed window cleaner
The roof fixed window cleaning machine is a product developed on the basis of the high working basket. Most of the high-rise buildings built in China in the 1980s and 1990s were designed by foreign architects. The installation of the window cleaning machine was considered in the design of the building, and the foreign window cleaning machine products were selected. The cleaning and maintenance of the wall has laid a good foundation.
At present, the roof fixed window cleaning machine has been rapidly developed in China, and has become a high-tech mechatronics equipment, which brings great inconvenience to the subsequent cleaning and maintenance. There are 2 sets of protection devices in the platform of the roof fixed window cleaner. When the platform load exceeds the rated load or the eccentric load is serious, the platform can't move; when the load is discharged within the rated range, it can be operated.
Because the operator does not pay attention, when the platform touches the obstacle, the impact bar acts, causing the lower abutting switch action, the platform parking can not run, but can run upward; the function protection of the roof fixed window cleaning machine is double protection. Increase the stability of the window cleaner.
Due to the inattention of the maintenance personnel, foreign objects are placed on or near the track of the chassis to cause the running resistance to increase. At this time, the chain is broken, the chain protection switch is activated, the power is cut off, the staff is checked for foreign objects, and the chain is resumed to prevent the accident from expanding. The roof fixed window cleaning machine has self-breaking protection for the small pinion. When the resistance is limited, the small pinion of the window cleaning machine self-breaks to protect the large shaft wheel and the reversing screw.www.chinagondola.com
