Link-Belt to Unveil 120-Ton Rough-Terrain Crane at Bauma
March 6, 2019 - Link-Belt Cranes will unveil its new 120|RT 120-ton rough-terrain crane at Bauma 2019 in Munich, Germany, booth number F903/3.
Link-Belt says the new crane offers a true 120-ton lift chart, operating efficiencies, and innovations that provide more efficiency and comfort.
Boom and Attachment
The 120|RT delivers outstanding reach with a six-section 38.3’–164.1’, pin-and-latch, formed boom built to Link-Belt’s specific boom profile and tolerances at its Lexington, Kentucky, facility.
An available two-piece, 35’-58’ on-board offsettable fly jib provides greater flexibility and range, and manually offsets at 0°, 15°, 30°, and 45°. One-person fly erection technology minimizes work at height with ground controls for fly assist and boom hoist cylinders. Two 16’ lattice insert extensions provide a maximum tip height of 261.7’.
The 120|RT’s six-speed transmission is powered by a dual compliant Cummins Stage V/Tier IV
QSB 6.7L 232 hp diesel engine. A Cummins Tier III QSB 6.7L 240 hp diesel is also available.
Four 29.5x25 tires are mounted on axles affixed to the carrier via greaseless four-link suspension, eliminating ten previous grease points. Centralized electrical locations, remote mounted filters, and easy-access fluid checks make routine service easy.
The 24-volt electrical system makes running diagnostics quicker and easier. The wiring is a Controller Area Network (CANbus) system. The 24-volt system yields the ability to multiplex with modules placed near dedicated functions like outrigger beams and winches. In total, there are five modules located throughout the machine that allow crane functions to continue working when other modules are being diagnosed or serviced.
Six points of access to the carrier deck are maintained with new ergonomic ladders. Regardless of slew angle, the operator has easy exit from the cab to the flat deck. The 120|RT exterior features durable textured paint, along with a new slip-resistant paint on the carrier deck to provide better footing.
V-CALC – RT Simple
Link-Belt’s V-CALC (Variable Confined Area Lifting Capacities) system features 81 outrigger configurations with real-time 360° charts. V-CALC has proven itself in general construction and infrastructure applications on the 75|RT. Once outriggers are set, the user-friendly Pulse 2.0 system indicates the crane’s available capacity. The system then previews the operator’s real- time capacities given the crane’s current configuration at the next five radii for a given boom angle.
Upon selection, Link-Belt Pulse 2.0 provides a live view of the working area with color-coded quadrants. If the chart exceeds capacity at a given slewing angle, swing arrest will start 5° before, bringing swing to a smooth stop.
High-strength steel in the upper frame accommodates a new winch design with ultra-wide drums for increased line pull at higher working layers. Maximum winch line pull of 23,632 lbs. allows a wider range of applications to meet contractor needs. Outboard hydraulic routings and wiring harness improvements offer form-fitted design for better serviceability. Three slabs of hydraulically removable upper counterweight totaling 28,800 lbs. come standard.
Introduced on the 75|RT in 2017, Link-Belt’s new cab for rough terrain cranes has been well received in the field, thanks to its visibility, operator comfort, and intuitive design. All electrical components coming into the cab are bulkheaded for “plug and play” assembly. Cab specifications include:
Ergonomic seat with electronic single-axis joystick controllers
Automotive-type, high capacity HVAC system
Increased storage and interior lighting
Time delayed wipers
USB and 12-volt power supply connections
Van-style pop out door
Link-Belt Pulse 2.0
Based on ongoing operator and customer feedback, Link-Belt Pulse 2.0 provides a simple interface for crane operators with a 10” touchscreen display, along with customizable programmable features. Link-Belt Pulse 2.0 can be updated and serviced remotely. Wi-Fi enabled, the system uses the serial number of the unit to determine whether updates are available, and downloads/installs to the appropriate controls.
Continuing a Focus on Work Conditions
Link-Belt carefully considers the location of swing out engine access doors and centralized electrical locations – keeping them accessible from the ground or near a grab handle or ladder. Transmission oil, engine oil, primary and secondary fuel filters, as well as the engine oil filter are mounted for easy reach.
The 120|RT has been fitted with all the tools to get the job done, any time of day:
Dual amber strobe lights
LED working lights
Work platforms on the upper with guardrails
Operator programmable function kick outs
Telematics in place to give real time data to better forecast maintenance and service needs of the crane.
Link-Belt’s camera vision package on the 120|RT enhances on-board site monitoring and includes a back-up camera, as well as cameras for viewing winches and the right side of the upper.
Transport at under 100,000 lbs.
The 120|RT will transport with base unit fully equipped minus modular counterweights at 94,472 lbs. and an overall height of 12’10.” It can be driven right off a conventional lowboy trailer, just needing its counterweight assembled before going to work.
