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.
