The Grove GHC85 telescopic boom crawler crane has a lifting capacity of 85 USt ton (80 mt) and features the longest boom in its class with a five-section 36.1′ – 137.8′ (11 – 42 m) full-power telescopic boom that comes with an optional stowable 10′ (3 m) heavy-duty, plus a 26.2′ – 49.3′ (3 – 8 – 15 m) 0°, 20°, and 40° offsettable two-section jib for a maximum tip height of 199′ (60.7 m).
This versatile telecrawler is ideal for use in utility applications, general construction work, bridgework, 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. It can be transported to the Jobsite in just three loads, or four loads when its crawlers are carried separately.
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 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 the 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,” 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 the high range, while creep speeds top out at 0.55 mph in low range.
Additional options, such as working range limitation and a cold-weather package, are appealing to those engaged in special civil and hydraulic engineering applications.
High and mighty
Offering elevations from -3° to +80.5°, the five-section main boom is adjusted via a four-stage cylinder and the heavy-duty jib with a 10° offset is 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.
The hoists are mounted over the rear counterweight, and 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 ability to view distant loads is improved in several ways, most notably through the standard 20° cab tilt. Other options include a radio remote control for operation from outside the cab, as well as a third hoist that is perfectly suited for foundation applications.
Crane Operators will appreciate the ergonomic benefits of the high-vis cab, such as the 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 controls 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.
The Grove GHC85 is the eighth model added to the telescoping crawler crane product range for the Americas.
The GHC Series telescoping crawler cranes have redefined industry standards. The GHC Series combines excellent gradeability and lift capacity with 100 percent pick and carry capability. GHC models come in a package engineered for exceptional operator ergonomics and maneuverability, thanks to the rugged, heavy-duty crawler tracks and telescoping boom.
