Manitowoc has added the eighth model to its telescoping crawler crane range, the Grove GHC85, in the Americas, which feature a capacity of 85 USt and the longest boom
The versatile crane is ideal for use in utility applications, general construction work, bridge work, pile driving, and as an assist crane for assembling other cranes. Frame-mounted jacks and counterweight lifting cylinders enable the crane to self-assemble, which can be controlled via a wireless remote.
Without the need for outriggers, the GHC85 can quickly move from one static pick to the next. Its ability to maintain 100% pick-and-carry capabilities on inclines up to 4° makes it suitable for repetitive utility work, such as setting poles, moving solar panels, or setting up larger cranes.
“The biggest advantage of a telecrawler is that you can work efficiently on both even and uneven terrain with solid pick-and-carry charts,” said JJ Grace, product manager for GHC cranes.
“The maximum track span is 16.7 ft, but one track could be at 100% and the other at 50%, enabling an operator to maneuver and pick in confined spaces,” Grace explained.
A Cummins B6.7L Tier 3 (218 hp / 164 kW) or Tier 4F (249 hp / 186 kW) engine powers the two-speed hydrostatic drive, giving the GHC85 a maximum speed of 1.43 mph in high range, while creep speeds top out at 0.55 mph in low range.
Offering elevations from -3° to +80.5°, the main boom length covers 36.1 ft to 137.7 ft. Its five sections are adjusted via a four-stage cylinder. A 49.3 ft bi-fold swingaway standard boom extension is offsettable at 0°, 20° and 40°, providing a useful point for attachments that are ideal for the utility sector. A 10 ft heavy-duty jib with 10° offset is another option, and it’s stowable on the left-hand side of the boom.
The main and auxiliary hoists’ piston motor and grooved drum facilitate two-speed spooling for smooth operation, with 591 ft of 20 mm wire rope providing a maximum permissible single line pull of 15,876 lb. The maximum single line speed is 360 ft/min.
