Tadano Mantis announces it has added a 35-ton capacity telescopic boom crawler crane to its product lineup, which offers many of the same features and benefits of the GTC Series but in a smaller package.
The 35-ton rating is usable capacity with a level ground load chart, which allows crane operation on slopes up to 1.5 degrees. The crane can be used to its full capabilities without the requirement of ground preparations to give a level lifting base. The load charts offer full chart pick-and-carry capacity through 360°.
Featuring a three-section, full-power boom, the GTC-35 has a maximum boom length of 89’3″. The boom is purpose-designed for the GTC Series crane and manufactured by Tadano Japan. It is suited for heavy-duty work, such as foundation, pick-and-carry, and lifting on slopes up to 4 degrees. The main boom is complemented with a 23’6″ to 42’0″ extendable jib that offsets at 5°, 25°, or 45° for a maximum tip height of 135’9”. Load charts for jib operation allow for lifting on slopes up to 2.5°.
The Tadano Mantis GTC Series offers OPTI-WIDTH for infinite symmetrical or asymmetrical track positions. The hydraulic track extension system on the undercarriage can adjust the operating width of the crane from 10’9” to 15’9” overall width (with 29.5-inch-wide track shoes) to provide the optimal lifting base based on site conditions. These telecrawlers do not require pinning of the track frames in fixed width positions, so it is ideal for the operator to be able to position the track width optimally for their lift work and to have the proper load charts automatically selected by the AML-C system.
OPTI-WIDTH load charts for asymmetrically positioned tracks have significant lifting capacity enhancements when compared to those for symmetrical track positions. OPTI-WIDTH incorporates zoned load charts, rotational position sensing, and function soft stops to ensure that the crane operator cannot swing with a load into a zone where the crane will be out of capacity.
The crane uses the full capabilities of the Tadano AML-C Rated Capacity Indicator and has operating load charts for 1.5°, 2.5°, and 4° slope with automatic out of level load chart switching based on the cranes position on the jobsite. It is also possible for the operator to set work zone limits for swing angle, height, and radius, and the crane has
function soft stops as operation approaches these pre-set operating limits.
With compact dimensions of 10’9” wide x 43’1” length x 8’2” height (with 29.5” wide track shoes), the unit has optional track shoes available that can reduce the minimum operating and transport width to 8’6”. The overall height can be reduced to under 8’0” to allow this low-profile crane access to sites that other cranes just can’t because of their height. Transport weight of the crane with the standard equipment package is 71,300 lbs, and the unladen ground pressure is 7.6 psi.
The crane is powered by a Cummins Tier 4f QSB4.5 diesel engine rated 173 hp @ 2,200 rpm. Engine throttle control is by auto-idle control, adaptive throttle control, or by foot pedal control. The load-sensing, power-controlled hydraulic system optimizes the hydraulic output to the diesel engine power output for efficient operation and control. The swing system is controlled by a separate closed loop hydrostatic transmission for superior swing performance – in either free swing, or hydrostatic controlled swing – and the maximum swing speed is 2.2 rpm. The travel system features two-speed track drives with maximum speeds of 2.1 mph and a maximum unladen gradeability of 70%.
Telematics with Hello-Net monitors machine work history, position data and maintenance data. The information can be accessed free of charge through the Tadano Hello-Net internet portal.
The units has a number of productivity enhancing options including an auger system, which was be mounted to the boom base section or to the second stage of the boom for variable radius drilling up to 54 feet at any position through the 360° rotation of the crane. The auger system can utilize auger drives with a maximum digging torque of up to 14,500 lb-ft. The two-person, 750-pound capacity WP-750 platform can be mounted to the main boom or the 23’0” offsetable jib for a maximum platform height of 120 feet. Hydraulic tool circuit with hose reel.
Other notable options are a hydraulic pole claw, cold weather packages for operation to -40° F, a radio control package, anemometer, and barge load charts.
