Link-Belt Rolls Out New 75-ton Rough-Terrain Crane

Link-Belt Construction Equipment has introduced the next generation of the rough-terrain crane: the 75-ton 75RT.

Link-Belt rough-terrain cranes have been proven performers among fleet and crane rental houses for 45 years.The 75RT continues that tradition.

It has outstanding reach for its capacity class and a new operator’s cab that elevates the experience of operating a Link-Belt crane.

The 75RT transports at less than 100,000 lbs. with full counterweight and less than 90,000 lbs. without counterweight.

It features a six-speed transmission powered by a Cummins Tier 4F QSB 6.7 270-hp diesel engine.


Reach and pull

            Link-Belt builds the five-section, 38- to 142-ft., full-power formed boom to a specific profile and tolerance in its production facility in Lexington, Ky.

To simplify the lifting process, only two boom-extension modes are offered: EM1 and EM2.

A two-piece, 35- to 58-ft. fly jib and a three-piece 10/35/58-ft. bi-folding fly jib are both available, for a tip height of 208.7 ft.

The matching main and auxiliary winches have 18,603-lb. (82.8 kN) maximum single-line pull and a maximum line speed of 485 fpm.

Pulse 2.0
            Pulse 2.0 is the next evolution of Link-Belt’s patented crane operating system. In addition to the intuitive design for the operator, which includes a larger 10-in. screen and added programmable features for greater customization, Link-Belt Pulse 2.0 can be updated and serviced remotely.

The system includes a Wi-Fi hub, uses the serial number of the unit to determine whether any updates are available, and downloads/installs them to the appropriate controls. Software maintenance can be accomplished in the field without a service call.

All new operator's cab
            Integral elements like the Link-Belt Pulse 2.0 display, visibility, and operator comforts have all been addressed. All electrical and hydraulic components coming into the cab are bulkheaded for “plug and play” assembly. The 75RT camera vision package enhances on-board site monitoring and includes cameras for viewing to the right side of the upper, the main and auxiliary winches, and backing up. Specific cab improvements include:  

10 in. (25.4 cm) touch display with pivoting adjustments
20% greater visibility
Bluetooth AM/FM radio
Larger, ergonomic seat with new single-axis electronic joystick controls
HVAC system cold/heat box tested to automotive standards
Increased storage and interior lighting
Time delayed wipers
USB and 12-volt power connections
Van-style pop out door
Variable outrigger charts integrated into the RCL
RCL display stays booted up even with engine off

V-CALC
            The 75RT will be the first Link-Belt crane to showcase V-CALC or Variable Confined Area Lifting Capacities. This new feature provides more selectable outrigger configurations by allowing outrigger beams (either fully retracted, intermediate, or fully extended) to be set up in pairs either from side-to-side or front-to-rear.

The Pulse 2.0 system senses the outrigger configuration, previews workable areas, and indicates a percentage of the crane’s that can be used in each area. The system also previews the next five radii for a given boom angle. When the operator makes a selection, Link-Belt Pulse 2.0 provides a live view of the work area.

Transport at under 100,000 lbs

            The 75RT has multiple transport options to accommodate road laws anywhere – it can transport fully equipped at just under 100,000 lbs., or under 90,000 lbs. with 14,500 lbs. of counterweight removed. The 75RT has an overall height of 12' 2.3" and can be driven right off a conventional lowboy trailer.

Electrical improvements and service

            Another new feature of the 75RT is the evolution from a 12V electrical system to a 24V. The wiring is a Controller Area Network (CAN bus) system, but the increased voltage enables multiplexing with modules placed near dedicated functions like outrigger beams and winches. The five modules located throughout the crane allow functions to continue working while modules are being serviced.
         Large swing-out doors and centralized fuses, relays, and breakers make checking powertrain components and fluid levels a snap. Folding ladders and upper guardrails provide reinforced safety boundaries. A centralized spot near the cab for checking pressures makes it easy for the operator to monitor systems from one location, and a centralized bank of grease fittings simplifies lubrication.


Other standout features of the 75RT:

Greaseless 4-link suspension
Industry-leading telematics give real time data to better forecast maintenance and service needs
Hydraulic disc brakes for both service brakes and parking brake
Full LED lighting package includes cab lights, headlights, turn signals, marker, backup, and braking lights
Powder-coated tubing is used throughout the crane
Well organized electrical and hydraulic routing
Solar powered aviation package available
Three lockable storage boxes
LED viewing lights on all four outrigger beams.
Supported 24/7 by Link-Belt Preferred including online manuals, literature, a ground bearing calculator, and 3D Lift Plan
iCraneTrax and 3D LiftPlan compatible
