Grove expands telecrawler portfolio with mid-size GHC85
Manitowoc has added an eighth model to its telescoping crawler crane range for the Americas.
The Grove GHC85 has a maximum capacity of 85 USt and the longest boom of its class. It is positioned in the middle of Grove's range of telecrawlers.
Designed for use in utility applications, general construction work, bridge work, pile driving, and as an assist crane for assembling other cranes, it has frame-mounted jacks and counterweight lifting cylinders enabling the crane to self-assemble, which can be controlled via a wireless remote. It can be transported to the jobsite in just three loads, or four loads when its crawlers are carried separately.
The GHC85 can move from one static pick to the next without the need for outriggers. It can maintain 100% pick-and-carry capabilities on inclines up to 4° making it suitable for repetitive utility work, such as setting poles, moving solar panels, or setting up larger cranes.
JJ Grace, product manager for GHC cranes said: “The biggest advantage of a telecrawler is that you can work efficiently on both even and uneven terrain with solid pick-and-carry charts.”
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.
The crane’s several track span settings, covering both symmetrical and asymmetrical configurations, are made possible by the hydraulically extendable and retractable cross members that enhance stability even further.
“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,” added Grace.
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.
Although the hoists are mounted over the rear counterweight, the in-cab monitor with a 7-inch screen provides an operator a way to closely monitor hoist operation. Standard rear and right-hand cameras improve awareness for the operator. Engine bay sound insulation enables quiet communication with riggers on the jobsite.
The operator’s cab features electric dual-axis controls, joystick control buttons for optional utility attachments, and the Graphical Rated Capacity Limiter. This system gives an audio-visual warning and control lever lockout whenever load limits are approached or exceeded, as well as providing data on boom angle, length, and radius, plus maximum permissible load, momentary load, and inclinometer readings. It has a 20° cab tilt as well as radio remote control and a third hoist that is perfectly suited for foundation applications.
