Manufacturer Link-Belt is bringing a new 100RT rough terrain crane to the market with the longest full-power boom available. “There’s not a full power boom out there that carries this capacity chart at radius,” said Brian Smoot, product manager telescopic rough terrain cranes. “This will be a dominant player for rental fleets, refineries, and plant work in general, handling longer radius with ease.”
Other notable features include Link-Belt’s latest operator cab design, Pulse 2.0 operating system with remote software updates via Wi-Fi, V-Calc asymmetrical outrigger options, a new simple-to-assemble fly, latest Cummins technology with a Stage V engine, and Link-Belt’s Vision package.
Shipments are scheduled to begin first quarter 2019.
Boom and attachment
The 100RT delivers outstanding reach with a five-section 40.6 - 155 foot full-power formed boom, the US manufacturer said, built to Link-Belt’s specific boom profile and tolerances at the Lexington, Kentucky, campus. A two-piece [35 - 58 feet] on-board offsettable fly provides greater flexibility and range, and can be manually offset at 2, 15, 30 and 45 degrees. A 16 foot lattice insert extension provides a maximum tip height of 237 feet.
The 100RT will be the first Link-Belt rough terrain crane with the new fly erection technology from the company’s latest telescopic truck and telescopic crawler cranes. A fly assist cylinder makes erecting and stowing the fly a one-person operation and minimizes work at height. Boom head speed screws and numbered spring loaded latches provide intuitive assembly. Given the natural elevation of a rough terrain crane boom, Link-Belt has simplified fly assembly with new ground level carrier controls. One control raises and lowers boom angle from 0 to -3 degrees, and another control is used for the fly assist cylinder.
The 100RT’s six-speed transmission is driven by a Cummins Stage V QSB 6.7L 232 horsepower diesel engine compliant with both Tier IV and Stage V standards. New greaseless 4-link suspension eliminates ten previous grease points. Centralized electrical locations, remote mounted filters, and easy-access fluid checks make routine service a breeze, the company said.
Wiring is a Controller Area Network (CAN bus) and the 24-volt electrical system can be multiplexed with modules placed near dedicated functions like outrigger beams and winches. In total, there are five modules 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 and, regardless of slew angle, the operator has easy egress to the flat deck from the cab. The 100RT exterior features all new durable “tough skin” paint, along with a new slip-resistant paint on the carrier deck to provide better footing for access and egress.
V-CALC – RT Simple
Link-Belt’s V-CALC (Variable Confined Area Lifting Capacities) system features 12 different outrigger configurations with real time 360-degree charts. V-CALC has proven itself in general construction and infrastructure applications on the 75RT. Outrigger beams (either fully retracted, intermediate or fully extended) are setup in pairs from side-to-side or front-to-rear. 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 radiuses for a set boom angle.
On 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 slew angle, swing arrest will initiate five degrees prior– allowing the crane to come to a smooth stop.
High strength steel used 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 pounds provides a wider range of applications and contractor needs. Hydraulic outboard routings and wiring harness improvements offer form-fitted design, providing greater serviceability over the life of the crane. Three slabs of removable upper counterweight totaling 28,800 pounds is standard equipment.
”There’s not a full power boom out there that carries this capacity chart at radius,” said Brian Smoot, product manager telescopic rough terrain cranes.
Introduced on the 75RT in 2017, Link-Belt’s new cab design for its rough terrain cranes has been well received in the field, in terms of visibility, operator comfort and intuitive design, the company said. All electrical components coming into the cab are bulk headed for “plug and play” assembly. Specifications include the following:
- 20 degree tilt
- Ergonomic seat with electronic joystick/single axis 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 larger 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 if any updates are available, and download/installs to the appropriate controls.
Continuing a focus on work conditions, day or night
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. Accessories fitted to the 100RT include the following:
- Dual amber strobe lights
- LED working lights
- Outrigger lights
- Work platforms on the upper with guardrails
- Operator programmable function kick outs.
Link-Belt’s camera vision package 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 pounds
The 100RT will transport with base unit fully equipped minus modular counterweights at 92,859 pounds. With an overall height of 12 feet, 10 inches. This rough terrain can be driven right off a conventional lowboy trailer, assemble counterweight and be ready to go to work.
