Tcrt Pcc No. 322 Location Exercise
TCRT PCC NO. 322 LOCATION EXERCISE Locate each item given and explain where you found it. If you have any questions, be sure to ask the trainer about them. Identify the purpose and manipulation of each item You may follow any sequence that is convenient for you, but be sure to locate every item indicated herein. A - Trolley pole hook-down warning Unlike the standard cars, the PCC trolley pole must be hooked down when not operating. This is necessary to avoid electrical injury, due to stored electrical power, to persons working on the car. Do NOT park the PCC in the barn or when disabled with the pole NOT hooked down! _________________________________________________________________ _________________________________________________________________ _________________________________________________________________ 04/18/10 -- Rev: Release – Prtd: 04/18/10 Page 1 of 8 B - Battery charger plug This connection is used to keep the batteries charged when the car is not in use. It must be plugged in at all times the car is in the barn. This plug must be disconnected before the car is moved. It is located under the rear anticlimber and to the pole (left) side of the car center. _________________________________________________________________ _________________________________________________________________ _________________________________________________________________ C - Earll retriever and trolley rope The Earll retriever acts as a reel for the trolley rope, keeping it taut when operating. If the pole dewires and tries to fly up, the retriever yanks it back down to limit the damage to the pole and wire. Many PCCs used a “catcher” which also acts as a reel but simply limits how far up the pole will jump if it dewires.
