DOVER ELEVATORS GD45 MACHINE GEAR MOUNTING BOLT FAILURE. (NEWFOUNDLAND ELEVATOR INCIDENT)
|
PROBLEM:
Dover GD45 machines, the bolt heads of the six 5/8" mounting bolts broke below the head, allowing the bolts to work out of the mounting holes of the gear and the spider. This condition allowed the gear to lose solid connection with the spider and cause loss of control between the drive sheave and the worm shaft. (Dover Drawing Number: 501294 attached)
ACTION:
| 1) |
|
(A.S.A.P.) Please check all GD45 machines and look for loose/broken or missing bolts that connect the gear to the spider. (Remove cover plate and try tightening bolt) |
| 2) |
|
If any broken bolts are located, the device is to be "removed from service" and AEDARSA is to be contacted (sample of damaged bolts required) for further action. |
| 3) |
|
Complete one safety bulletin form per building inspected. Please forward this information to AEDARSA. |
| 4) |
