Our large capacity MR Series of motorized trolleys offers the horsepower and precision required to transport and position extremely heavy loads. Designed with either 4 or 8 wheels to spread the weight across a wider wheel base, they easily move the ER large capacity hoist and its load from one location to the next.

Refer to pages 4, 5, 6 and 7 for features and benefits and page 26 for standard hoist specifications.
