Manitowoc has added an eighth model to its telescoping crawler crane range in the Americas. Featuring a capacity of 85 USt and the longest boom of its class, the Grove GHC85 is positioned in the middle of Grove’s range of telecrawlers.
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 36-inch triple-bar grouser shoes on the tracks offer a high level of stability, in addition to reducing soil compaction, by producing ground bearing pressures as low as 13.2 psi without load, and as high as 24.9 psi with load.
A Cummins B6.7L Tier 3 (218hp / 164kW) or Tier 4F (249hp / 186kW) engine powers the two-speed hydrostatic drive, giving the GHC85 a maximum speed of 1.43mph in high range, while creep speeds top out at 0.55mph in low range.
Offering elevations from -3° to +80.5°, the main boom length covers 36.1ft to 137.7ft. Its five sections are adjusted via a four-stage cylinder. A 49.3ft 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 10ft 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 591ft of 20mm wire rope providing a maximum permissible single line pull of 15,876lb. The maximum single line speed is 360ft/min.
