Six Reasons to Choose a Grove GRT655 or GRT655L Rough-Terrain Crane
Since the launch of the Grove GRT655 and GRT655L rough-terrain cranes in 2017, they have proven a popular model because of their flexibility.
Manitowoc offers the 55-USt rough-terrain crane with two boom versions for different applications: the GRT655 with a 114’ four-section, full-power boom for heavy duty applications and the GRT655L with 141.2’ five-section, full-power boom. An optional 26’ – 45’ manually offsettable telescopic swingaway jib extension adds to its lifting capabilities.
Here are six reasons behind the success of these models.
1. The GRT655 and GRT655L offer high capacity and reach in a compact format
At 141’, the Grove GRT655L has the longest boom in its class. Working with a jib, operators can reach up to a 197’ (60m) maximum tip height. The standard boom version, the GRT655, has the strongest load charts in its class. Both models feature a lightweight and compact design, with a GVW less than 38.5 USt and a carrier that measures less than 10’ in width. Crane operators can drive into narrow spaces such as refineries, power plants, and densely populated areas and access a greater variety of job sites. The GRT655 and GRT655L also offer very high single-line hoist speed and pull, making them very productive cranes that complete the job quickly.
2. The GRT655 and GRT655L are extremely 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 in one complete load. In addition, 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 21’, allowing it to access even the most congested sites.
3. Operation of the GRT655 and GRT655L is quick and intuitive
The Manitowoc Crane Control System (CCS) makes it intuitive to set up, control, and command the crane. This system is in common with all-terrain cranes, as well as truck-mounted and crawler cranes. Data is put into the CCS using a jog dial on the right armrest and/or the buttons on the two displays. The speed and ramp of each movement can be customized according to individual operator preferences. Advanced troubleshooting and diagnostics are provided on board.
4. Comfort and visibility from the GRT655 and GRT655L cab is unmatched
The GRT655 and GRT655L have a full vision cab with minimal blind spots. In addition, the cab can tilt up to 20°. The heating and air conditioning system, with multiple vents to increase air flow, helps the operator stay focused and comfortable. When entering and exiting the cab, flat decking on the chassis, grab handles around the cab, and steps to access the crane on all four sides offer support, ensuring the operator can maintain a three-point contact with the crane at all times.
5. The GRT655 and GRT655L have a 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 outriggers’ jack cylinders upside down, the chrome part of the cylinder and the seals are protected against sand, dust and general contaminants. It has a hydraulic braking system, instead of the pneumatic variety often seen in the industry. This eliminates the need for a separate system and maintenance. ECO mode and the hydraulic load sensing system reduce fuel consumption by up to 30% compared to older models. 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.
6. Grove GRT cranes come with a two-year standard warranty
The GRT655 and GRT655L come with a standard two-year or 4800-hour warranty with bumper-to-bumper coverage. The warranty program proves out the dependability of Grove’s GRT rough-terrain cranes, which have benefited from extensive design improvements and rigorous reliability testing at Manitowoc’s Product Verification Center in Shady Grove, Pennsylvania, to ensure quality.
