Link-Belt announces revolutionary hydrostatic 6x6x6 drive/steer,
100-ton rough terrain crane
LAS VEGAS (March, 2002) — Link-Belt Construction Equipment Company announced its’ revolutionary new design for big rough terrain cranes at CONEXPO-CONAGG in Las Vegas. The RTC-80100 Series II 100-ton (90 mt) rough terrain crane with its revolutionary hydrostatic drive on a 6x6x6 carrier design, with 23.5R25 size wheels, provides breakthrough transportability and jobsite maneuverability features not found on any rough terrain crane in its class. In addition to the revolutionary carrier design for cranes, Link-Belt has also matched this 100 tonner up with its new ‘formed’ boom design. This new boom design not only delivers full power boom and telescoping load capability but also delivers a superior load chart and a maximum tip height of 243’ (69.49 m) with full attachment.
Breakthrough transportability for big RTC
Unlike any other rough terrain crane in this class, in less than an hour, without a helper crane, the RTC-80100 is stripped to less than 90,000 lbs. and is ready for transport. Unlike other big RT’s, the tires do not need to be removed for transport. Only the counterweights and outrigger boxes need to be removed to get the crane’s vehicle width to 10’ (3.05 m). Because it is under 10’ wide and features a low 12’ 2.5”, (3.72 m) overall height, the RTC-80100 Series II incurs no daytime or weekend travel restrictions unlike competitor’s cranes which exceed width and weight restrictions, which require special permits.
The crane ships in two loads. Using an 18” conventional, drop deck trailer the crane unit is easily loaded out. The second truck handles the counterweights, fly extensions and outrigger boxes.
Maneuverability redefined
Not only is the RTC-80100 Series II easy to get from jobsite to jobsite, it also has extraordinary on the job maneuverability. Because of the innovative 6x6x6 hydrostatic drive/steer on each wheel, the turning radius of the 26’ (7.92 m) long carrier is a remarkable 21’ (6.4 m). The RTC-80100 has a choice of four steering modes; front only, coordinated six-wheel, six-wheel “crab,” and rear only. With the smaller tires giving it an overall height of 12 ‘ 2.5 “ (3.72 m) along with its’ individual wheel hydrostatic drive, there is no crane in the world, any size, that can come close to the job site maneuverability and performance of the RTC-80100.
On the job, the RTC-80100’s outstanding 45 ton pick and carry capacity coupled with its long reach, maneuverability, incredible gradeability and low height make it truly an ideal solution for industrial sites.
Link-Belt’s new, innovative boom design
Introducing a new boom design, Link-Belt is unveiling the next generation formed boom design to meet greater length and stability requirements. The U-shaped, formed construction boom design offers exceptional strength and stability throughout the crane’s chart. Strategically placed wear pads are utilized throughout the boom to disperse the load to maximize the overall boom strength and stability providing greater capacities at longer load radii.
The crane’s standard boom is a five-section, full-power, 150’ (45.72 m) design with a quick reeve boom head. The main boom maximum tip height is 159’ 6” (48.62 m). With the optional 31’ to 55’ (9.44 – 16.76 m) two-piece (bi-fold) fly, the maximum tip height is 214‘ (65.23 m) and is stowable and offsettable to 2, 25 and 45 degrees.
When not in use there is no deduct necessary for the jib when stowed. Also available are optional 15’ (4.57 m) fly extensions that can be added to extend the bi-fold attachment to 70‘ with one section and 85‘ using two sections. The maximum tip height with the bi-fold attachment and one extension is 228.5’ (69.64 m). With two extensions the maximum tip height is 243’ (74.07 m).
The RTC-80100 Series II offers three boom modes; Standard, A-max1 and A-max2. In the A-max1 mode, the boom is 95’ (29 m) in length. The inner and center sections are extended, offering maximum strength. In the A-max2 mode, the boom length is 122.5’ (37.34 m). The tip, outer and center sections are extended yielding maximum stability. The RTC-80100’s full power boom can telescope loads of greater capacity than the power-pinned booms utilized by many competitors’ machines. The full-power boom will appeal to rental houses because of the simplicity of operation.
The RTC-80100 Series II is powered by 300 hp. (224 kW) Detroit Diesel Series 40, six-cylinder diesel engine with 1,050 ft-lb. (1,424 nm) of torque. Hydrostatic powered radial wheel motors in each wheel yields outstanding creep control and jobsite maneuverability. Both the front and rear suspensions are fully independent with lockouts.
“We are very excited about the prospects of the RTC-80100 in applications where big capacity, reach, maneuverability, low overall height and ease of transport are all key,” said Bill Stramer. “We think the RTC-80100 is right on the mark with its innovative features.”
