Since its launch in 2017, the Grove GRT655’s flexibility has made it popular on jobsites across the world. The crane offers high capacity and reach in a compact design. Here are five reasons behind the success of this crane.
1. High capacity and reach in a compact format
The Grove GRT655L has the longest boom in its class (43 m [141.2 ft]), meaning no additional jib is needed for most long distance jobs. The standard boom version, the GRT655, boasts the strongest load charts in its class and is the preferred choice when extra capacity is needed. Both units share a light and compact carrier, weighing only around 35 t (38.5 USt) and measuring less than 3 m (10 ft) in width, making them ideal for narrow spaces and enabling access into a large variety of jobsites.
2. Easy to transport and maneuver
The narrow dimensions of either model — the most compact in their class — make the GRT655 and GRT655L easy to transport on a trailer and they can be shipped in one complete load. When maneuvering around a jobsite, operators benefit from all-wheel steering with a choice of four steering modes — two-wheel front, two-wheel rear, four-wheel crab and four-wheel coordinated. In coordinated mode, the crane has a turning radius of just 6.4 m (21 ft), allowing it to access even the most congested sites.
3. Operation is quick and intuitive
Manitowoc’s Crane Control System (CCS) makes it intuitive to set up, control and command the crane. This system is in common with rough-terrain cranes, as well as all-terrain and truck-mounted cranes. Data is put into the CCS using a jog dial on the right armrest and/or the buttons on the two displays. This can easily be done even when wearing gloves. Operators on any level will benefit from the crane’s intuitive commands, and advanced troubleshooting and diagnostics are provided on board. The high single line hoist speed and pull makes the cranes complete the job quickly.
4. Unmatched cab comfort and visibility
The cranes have a full vision cab with minimal blind spots. The cab can be tilted up to 20 degrees, helping the operator to stay comfortable and productive when working with the 43 m (141.2 ft) long boom or a jib on top of that. The GRT655 and the GRT655L are the only 60 t (55 USt) rough-terrain cranes with a tiltable cab. Effective heating and air conditioning system, with multiple vents to increase air flow, also helps the operator to stay focused and feel comfortable even on hot summer days. Smart cab ergonomics ensures the operator can maintain a three-point contact with the crane at all times.
5. Low total cost of ownership
The GRT655 and GRT655L include many features that reduce maintenance requirements and increase component service life. For example, by mounting the outrigger jacks upside down, the chrome part of the cylinder and the seals are protected against sand, dust and general contaminants. The hydraulic braking system minimizes maintenance, and the ECO mode reduces fuel consumption by 30%. The hydraulic load sensing system sends oil only when it is needed, leading to less overheating, less wear and less fuel consumption. These savings combine to deliver a low total cost of ownership.
