6W

ID/Name: 6W
Type:  Gangers (Patrolman) Trolley
Description: 4 Stroke 4 man Trolley
Built: 1953
Status: Restored

The KS trolley became the 6W when the engine in it was replaced with the Wisconsin AENLD 9.2 hp engine, and the Granite State Machine Co. model 5101E reversing gearbox.

When the KS became the 6W, the seat was too narrow to fit the Wisconsin engine with its upright cylinder between the seat frames, so the VR widened the seat by welding in some L shaped gussets into the seat frame. This also necessitated drilling three new holes in the seat timber to keep the handbrake ratchet relative to the ferodo drum brake mechanism. And this is why there are three holes in the metal seat frame that line up with the handbrake ratchet, but are a few inches away. The slide mechanism to tighten the belt was ditched for a chain drive, and a piece of 1/4" plate welded to the middle frame rails to hold the Wisconsin and gearbox. It’s believed Naismith Engineering was the firm that organised this modification.

They still sell the same Granite gearboxes, the design hasn't changed in 30 years".
