Elec/Hyd & Hydraulic Cranes

Introducing Our New EH4520/H4520 & EH5520/H5520 Cranes

EH5520_Crane_pic_1.pngMaintainer Corporation has added two new 20’ electric-hydraulic and hydraulic cranes to its innovative line of work truck cranes. 

The EH5520 has a 30,000 foot*pound crane rating and has maximum lift of 5,500 pounds. The EH4520 can lift 4,500 pounds and has a max lift moment of 20,000 foot*pounds. The cranes feature a planetary winch mounted on the boom to maintain cable tension.

“After a brief hiatus in offering the electric over hydraulic cranes,” said Tom Wibben, Sales and Service Manager for Maintainer, “we are now able to offer high-quality Maintainer options for customers who prefer the EH option for their service trucks.”

EH5520_Crane_pic_4.pngThe new cranes are mounted with a universal 14.75” x 14.75” bolt pattern, which allow the cranes to be added to a variety of truck bodies. The EH5520 and EH4520 are only available in the short-tower design and include several popular features:

  • They have a 3 gallon-per-minute power pack for maximized crane speeds.
  • There is a self-protecting thermal shutdown built into the 12-volt DC motor.
  •  A proportional wireless crane remote is standard.
  •  An optional battery isolator is available to keep the crane battery charged while avoiding a drain on the chassis battery.

The new cranes will also be offered in full hydraulic versions as well (H4520-ST and H5520-ST). The cranes offer 580 degrees of rotation and boom elevation from -13° to +78°.
