| Elevator maintenance inspections |
In the past, the task of maintaining and inspecting hot elevators at this asphalt plant involved heavy manual handling and “live working”. Now, a vehicle winch is used, which is fixed to the maintenance truck and powered from 12V battery. This means that the plant can be fully locked off.
Engineered on site, a small extension was welded to the bottom elevator shaft. The simple task is to slide a hub wheel onto the bottom shaft, then attach the winch cable to the hub. The cable is wound onto the hub before being secured to the shaft using a locating pin. The easy fit guard to protect the operator from any moving parts can then be fitted into place. The winch is activated with a remote switch held by the fitter. The elevator now moves in a slow, smooth and controlled manner. If work is needed on the elevator, a lock off / isolation is fitted to the 12 volt battery supply.
