To further expand the capabilities of our NER/ER line of electric hoists, the MR Series of electric trolleys was developed. They feature an innovative side guide roller system that results in very smooth travel along the beam. Harrington’s MR trolley provides the mobility needed in a wide variety of industrial applications.

Refer to pages 4, 5, 6 and 7 for features and benefits and page 8 for standard hoist specifications.
