Grove GRT8100-1 rough-terrain crane features capacity improvements, great fuel efficiency
Manufacturers are always finding ways to improve products. Manitowoc (Grove’s parent company) recently introduced its new 100-ton-capacity Grove GRT8100-1 rough-terrain crane — the upgraded version of its popular GRT8100 — that features a new carrier with the MAXbase variable outrigger positioning system, which enables better lifting capacity and site access.
The new carrier paves the way for a host of ergonomic improvements with its flat, aluminum decking that allows for better rigging and maintenance access. Storage is improved with the addition of space around the front deck as well as a box and headache ball tray to the right-front side. On the left side, below the new cab, there is space to stow cribbing mats, while a compartment just above this includes additional storage and facilitates easy ground access to the carrier’s electrical components.
The GRT8100-1’s new chassis shares commonality with the chassis from the proven 120-ton-capacity GRT8120. With the new chassis, users have the option to integrate the highly flexible MAXbase, which offers up to 15% capacity improvements in certain configurations. It simplifies setup on congested job sites, with each of the four hydraulically telescoping outriggers extended over a range of symmetric and asymmetric positions. Also new to the outrigger design is an auto-level feature for easy setup, as well as Manitowoc’s smart, length-sensing Outrigger Monitoring System (OMS).
More power, operator comfort
The crane also has a 300-horsepower Tier 4 Final engine that delivers approximately 10% more power and greater fuel efficiency. Manitowoc’s Crane Control System (CCS) helps deliver significant savings in total ownership costs, allowing the 6-cyclinder, turbocharged and water-cooled engine to operate in ECO mode. The reduced engine speeds that promote improvements in fuel efficiency have been aided by the torque converter installed with the new Rangeshift transmission.
Manitowoc improved operator comfort with a wider Full Vision cab that features a tilt/telescopic steering column; a wider, heated, electrically adjustable seat; and a three-camera package that maximizes visibility around the crane. Additional new features include an LED lighting package, footrest bars, improved foot pedal spacing, and CCS mounted on adjustable arm rests.
The GRT8100-1 maintains the 360-degree load charts of its predecessor, as well as the same overall dimensions, counterweight and five-section 39.2-foot to 154.3-foot full-power MEGAFORM boom.
“With the GRT8100-1, we have taken a great crane and made it even better,” said Manitowoc Product Manager John Bair.
