NERM/ERM Electric Trolley Hoist - 3 Phase

One Smooth Operator

Add a MR motorized trolley to your Harrington NER/ER electric hoist to increase productivity and decrease unwanted movement so you can easily direct your load. Opt for an adjustable two-speed unit with a variable frequency drive (VFD) and you’ll also be able to set your speed preference and ensure super smooth starts and stops every time.

Adjustable Two-Speed Trolleys

Get excellent traversing motion and load control with a variable frequency drive (VFD). The MR trolley’s programmable VFD provides gradual starts and stops to reduce unwanted movement while travelling.

UL Listed

Most models are certified and listed to UL 1340 “Standard for Hoists.”

Innovative Side-Guide Roller System

Designed for very smooth travel along the beam, the MR motorized trolley uses an innovative side-guide roller system that keeps the load controlled and on track while traversing.

Green Initiative

Built smarter without the use of harmful materials. Environmentally friendly.
RoHS compliant.

Drop Stops and Rubber Bumpers

Drop stops and rubber bumpers not only provide additional security for the operator, they also protect the equipment against collisions.
