NERM/ERM Large Capacity Trolley Hoist 3-Phase
Think Big. We do.
MR trolleys are suitable for harsh or outdoor applications and easily couple with NER/ER large capacity hoists for the heaviest lifting and traversing requirements. Features include thermal motor protection, side guide rollers for smooth operation and plug in electrical connections.
Rubber Bumpers
Rubber bumpers are standard on all motorized trolleys to provide protection from collisions.
Side Guide Rollers
MR trolleys include four ball bearing supported side guide rollers that contribute to smooth trolley motion and reduce wear of the wheels and beam.
UL Listed
Most models are certified and listed to UL 1340 “Standard for Hoists.”
Dual Speed Trolley VFD
Get excellent traversing motion and load control with a variable frequency drive (VFD) on dual speed MR trolleys. The programmable VFD provides gradual starts and stops to reduce unwanted movement while travelling.
NER Hoist
Harrington's (N)ER enhanced features three phase electric chain hoists are equipped with the latest technology in the market today. All models include a low headroom, lightweight body with a fan-cooled motor, standard thermal motor protection and a count hour meter for preventive maintenance. A secondary mechanical load brake is an additional features on ER models only. Simply the best hoists on the market!
