Why is the elevator rail installed on the bracket only fixed with a press plate and not bolted by welding or punching?
The weld point is fatigue, and the bolt falls off in case of shock
The welding is dead and cannot be adjusted
Reverse: why is the rail connection fixed without welding? Why bridge butt is not directly poured dead or welded directly after the completion of the whole board?The elevator guide rail is fixed and fixed by a press plate through a fixed bracket, and it is a method that has been approved and accepted in the process of elevator installation. Seasonal temperature difference on earth is very easy to cause the rail thermal expansion and contraction, allow the existence of a gap between the rail, usually not more than 0.5~1mm (rail type different requirements), mainly to consider the guide because expansion season, so can not be welded rail is fixed.
