Since the Grove GRT655 and GRT655L rough terrain cranes were launched in 2017, their flexibility has made them popular on construction sites around the world.
Manitowoc offers the 60 t rough terrain crane with two jib versions for different applications: the GRT655 with 34.8 m boom for heavy duty applications and the GRT655L with 43 m long boom for applications where reach is important.
Here are just five reasons these models are so successful.
1. The GRT655 and GRT655L offer high capacity and range in a compact format
At 43 m, the Grove GRT655L has the longest boom in its class. With this long boom, the rough terrain crane has the advantage that no additional boom is required for long-distance operations. And when working with a boom, operators can reach more than 56 m and almost 60 m at maximum center height. The standard boom version, the GRT655, has the strongest capacity charts in its class and is the preferred choice when additional capacity is required. What both models have in common is a light and compact beam that weighs only around 35 t and is less than 3 m wide. This allows crane operators to drive into tight spaces such as refineries, power plants and densely populated areas and reach a wider variety of construction sites.
2. The GRT655 and GRT655L are extremely easy to transport and maneuver
The narrow dimensions of both models – the most compact in their class – make the GRT655 and GRT655L easy to transport on a trailer and can be transported in a full load. In addition, when maneuvering on a construction site, the driver benefits from the all-wheel steering with a choice of four steering modes – two-wheel front, two-wheel rear, four-wheel crab steering and four-wheel coordinated. In coordinated mode, the crane has a turning radius of only 6.4 m and can therefore also reach the busiest construction sites.
3. The operation of the GRT655 and GRT655L is quick and intuitive
The Manitowoc Crane Control System (CCS) enables intuitive setup, control and control of the crane. This system is common to all-terrain cranes as well as truck and crawler cranes. Data is entered into the CCS via a jog dial on the right armrest and / or via the buttons on the two displays. This is also possible without any problems with gloves. The speed and ramp of each movement can be adjusted to the individual preferences of the operator. Many options are available for the less experienced to the most experienced operator, and advanced troubleshooting and diagnostic functions are provided on board. The GRT655 and GRT655L also offer very high single line hoist speed and pulling power, making them very productive cranes that get the job done quickly.
4. The comfort and visibility in the cab of the GRT655 and GRT655L are unparalleled
The GRT655 and GRT655L have a full view cab with minimal blind spots. In addition, the cab can be tilted by up to 20 degrees so that the driver can remain comfortable and productive while working with the 43 m long boom or a boom above it. The GRT655 and GRT655L are the only 60 t rough-terrain cranes with a tilting cab.
The effective heating and air conditioning system with several ventilation openings to increase the air flow also helps the driver to feel concentrated and comfortable even on hot summer days. When getting in and out of the cab, a flat chassis on the chassis, handles around the cab and steps to access the crane on all four sides, so that the driver can have three-point contact with the crane at all times.
5. GRT655 and GRT655L have a low total cost of ownership
The GRT655 and GRT655L contain many functions that reduce maintenance requirements and increase the service life of the components. Incorrect assembly of the cylinders of the support legs, for example, protects the chrome part of the cylinder and the seals from sand, dust and general contamination. In addition, it has a hydraulic braking system instead of the pneumatic variant often used in the industry. Grove rough-terrain cranes eliminate the need for a separate system and maintenance. Finally, the 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, resulting in less overheating, less wear and tear and less fuel consumption. These savings combine to result in a low total cost of ownership.
