200-foot boom added to successful HTC-8670

Lexington, Ky. (March, 1999)  –Link-Belt announced the HTC-8670LB (Long Boom), 70-ton (63.5 mt) hydraulic truck crane, which breaks the 200-foot tip height barrier with a four-section boom. The HTC-8670, one of Link-Belt’s most successful cranes, now becomes even more dominating in its class with a 127-ft., quick reeve, full power boom.

Exceeding 200 foot of tip height with only a four-section boom, this crane offers the operator the capability to fully extend and retract the full boom in less time than competing cranes with five-section booms. The HTC-8670LB’s boom is lighter per foot, which enhances its overall strength and performance.

The HTC-8670LB features a standard 41 to 127 ft. (12.50 to 38.70 m), full power, quick reeve four-section boom with a maximum tip height of 200 ft. (60.96 m) with a two-mode telescoping proportioning system (A-max) for optimum strength and stability charts. Two new swing away attachments are available including a 39.5 ft. (12.04 m), one-stage, swing away attachment and a 39.5 to 67 ft. (12.04 to 20.42 m), two stage, swing away attachment. Both attachments offset to 2, 20 and 40 degrees. Designed with the operator in mind, the HTC-8670LB also has no deducts in capacity for stowed attachments, simplifying the crane’s capacity charts.

The HTC-8670LB includes two Link-Belt exclusive boom design features — the exclusive "A-max" boom mode and the "BOSS." For in-close, big picks, the "A-max" mode (or mode A) allows the operator to extend only the inner-mid section of the boom to maximize the crane’s optimum strength and stability. The "BOSS" is a patented Link-Belt telescopic boom design of high-strength angle chords (corners) with high formability sidewall embossments with no welds, places the most steel at the corners where the maximum stress is concentrated.

The HTC-8670LB, with a powerful 365 hp. Detroit Diesel, Series 60 engine with 1,350 lbs. of torque easily merges safely into highway traffic and can maintain travel speeds in excess of 60 mph. An Eaton RTO-14909MLL thirteen-speed manual transmission is standard.

The new HTC-8670LB is equipped with Link-Belt’s exclusive CALC system, which allows operators to work in confined work areas where full outrigger extension is not possible. The CALC system provides three outrigger positions, fully extended, intermediate and fully retracted.

The HTC-8670LB is also equipped with a new hand-held outrigger control, with an 8 foot umbilical cord, that enhances the operator’s ability to position the outriggers.

A standard Link-Belt feature is the Microguard 434 Rated Capacity Limiter (RCL) with operator-defined parameters and alarm. By setting two points, the operator creates an imaginary vertical plane to maintain safe working distance from any nearby obstacles. Should the crane’s boom go outside the operator-defined limits, the RCL will sound an alarm. The RCL also improves the crane’s efficiency and production by ensuring the crane is operated within the lift chart.

The HTC-8670LB features the environmental Ultra-Cab of LCM•2000 construction process featuring laminated fibrous composite technology that provides optimum strength and stiffness.

The Ultra-Cab is roomier and quieter than traditional cabs. The overhead console contains a full complement of easy to read and comprehensive backlit gauges as well as rubber encased toggle switches for protection against dust and moisture. Corner-post-mounted gauges monitor critical machine information, such as oil, fuel and water levels.

An automotive style windshield and large side and overhead windows provide the operator with 25% more glass for a full vision-working environment. The dash-less design, lift up arm rests and a wide opening slide-by-door allows operators to enter and exit the cab with ease.

The HTC-8670LB features the Packard Electric Metri-Pack wiring system. Each wire and connector in the system is sealed to help prevent corrosion and costly downtime of machines. In addition, all wires have an automotive-type flame retardant cross-linked polyethylene insulation, resulting in a higher heat resistant wiring system.

Another Link-Belt design standard featured on the HTC-8670LB is the innovative two-part paint coating technology coupled with a pre-assembly paint process to provide the finest quality coating system available today. This coating technology provides superior adhesion and abrasion resistance. In addition, because all parts are painted before assembly, 100% coverage of each part is realized. This process also enhances the overall aesthetic appeal of the final machine, as nuts, bolts, hoses and a multitude of parts are no longer painted. As a result, paint chipping, cracking and deterioration is significantly reduced when service work and disassembly are required.

The HTC-8670LB is designed and manufactured under the ISO 9001 certification. This quality design process has lead to the development of this crane with a superior lift chart, rugged design style, and maximum reliability.
