The Range That Gets In.
The crane that earns its place on the hard jobs.
When the site is rough, the access is tight, and the lift chart still has to hold up, that is where Grove rough terrain cranes perform.
The range runs from 30 to 150 tonnes, with MEGAFORM boom technology and class-leading load charts across the board. TRT stocks parts and provides factory-trained service across New Zealand and Australia, so support is always close.
Grove rough terrain cranes are built around one principle: the site should never stop the lift.
MEGATRAK suspension keeps the machine planted on uneven ground, and MEGAFORM booms deliver reach that punches above the crane's weight class on every model in the range.
-
MEGAFORM Boom
Grove's patented MEGAFORM boom profile carries more load at greater extension than a conventional boom section, delivering lift capacity that belongs to a larger crane class.
-
MEGATRAK Independent Suspension
MEGATRAK independent suspension holds the machine level on uneven terrain, so the operator keeps working on ground that stops other cranes.
-
Crane Control System (CCS)
Manitowoc's Crane Control System gives operators real-time load and position data through two vertically mounted graphic displays, keeping every lift clear and controlled.
-
ECO Mode and Load-Sensing Hydraulics
ECO mode and load-sensing hydraulics match power output to what the lift actually demands, cutting fuel consumption without sacrificing response when full power is needed.
-
Full Vision Cab
The full vision cab maximises sightlines to the load and the site, keeping operators accurate and alert across a long day in demanding conditions.

Manitowoc Crane Care by TRT
Every Grove crane sold through TRT is backed by Manitowoc Crane Care, with factory-trained technicians, genuine parts, and service coverage across New Zealand and Australia.
Capacity for Every Challenge
At 150 tonnes and 62.5 metres of main boom, the top of the Grove RT range sits in territory usually occupied by crane classes with far larger footprints.
At the other end, the RT530E-2 delivers 30 tonnes of capacity in a narrow, low-profile package that moves between jobsites without a support convoy.
The full model range and specifications are available by request through TRT.

Frequently Asked Questions
-
What is the difference between the RT models and the GRT models?
The RT prefix designates models in the traditional rough terrain range, running from 30 to 65 tonnes with four and five-section full power booms.
The GRT prefix identifies Grove's higher-capacity rough terrain cranes from 51 to 150 tonnes, which incorporate technologies like MEGATRAK suspension and MAXbase outrigger systems more typically found on all-terrain cranes.
TRT can walk you through which configuration suits your most common lift scenarios.
-
Can these cranes travel on public roads between sites?
Grove rough terrain cranes are single-engine machines, so road travel requires transport on a low loader rather than self-propelling on public roads.
Their compact dimensions, particularly on the smaller RT models, are designed for straightforward loading and minimal transport restrictions. TRT can advise on transport configurations and local compliance requirements for specific models.
-
What does the MAXbase outrigger system do, and which models have it?
MAXbase allows operators to set outriggers in asymmetric configurations rather than requiring full outrigger spread on all four corners.
On a constrained site where one side is against a wall or fence, this opens up lift positions that would otherwise be unavailable. It is available on the GRT8100-1, giving that model a significant advantage in confined industrial or construction environments.
-
How is service and parts handled for Grove cranes in New Zealand and Australia?
TRT delivers Manitowoc Crane Care for the Grove range across both New Zealand and Australia. That covers planned maintenance, emergency callouts, genuine Grove parts, and repairs including boom and structural work.
TRT's crane technicians are factory-trained on Grove equipment, and the parts inventory is stocked to minimise downtime. Whether you are based in a main centre or working regionally, TRT maintains service coverage.
-
Which model is best suited for work in tight urban or industrial sites?
For tight sites, the RT530E-2 and RT540E offer the best combination of capacity and compact dimensions in the range. Both are built for accessibility, with narrow width and low transport height front of mind in their design.
For heavier lifts in confined spaces, the GRT8100-1 with its MAXbase outrigger system gives operators asymmetric outrigger capability, which is often the deciding factor when space is constrained on multiple sides.
-
What warranty comes with a Grove rough terrain crane purchased through TRT?
Warranty terms for Grove cranes purchased through TRT are provided at the point of sale and vary by model and configuration.
TRT recommends discussing warranty coverage and any available extended service agreements at the time of purchase, as Manitowoc Crane Care plans can be structured to extend coverage and lock in maintenance costs over the machine's early working life. Contact TRT directly for current warranty terms.
