(d) Wheelbase range shall be 13 feet
(e) Units shall have liquid detection system
(f) Ram locking start height shall be minimum 8.5 inches
(g) Lifting Rate: 90 seconds; 45” (1,140 mm) per minute, minimum.
(h) Moveable and fixed lifting units synchronization: 2” (50 mm).
(i) Lifts are to be provided with appropriate corrosion protection for an industrial bus repair facility and local environmental factors.
(j) Lifts must be equipped with home pockets for saddles to sit flush with floor surface creating an unobstructed floor, free of tripping hazards
(k) Provide front and rear hoist adapters, supplied for each individual lift, capable of lifting all of Winnipeg Transit buses and compatible with existing sets.
(m) Unit floor frames shall be structural and have the option to be installed suspended from a thickened slab or on a load bearing foundation slab.
