The Mantis GTC-350 by Tadano is a tele-boom crawler crane that's powerful and versatile. Made with massive steel fabrications with diesel engines and state-of-the-art hydraulics, this crane can get the job done. For better job site management Mantis has incorporated telematics capabilities using machine data logging and monitoring system with HELLO-NET, accessible via the Internet.

The Tadano GTC-350 has a maximum lifting capacity of 31.75 metric tons (35 US tons). A 3-section full power telescoping boom system that consists of one double-acting hydraulic cylinder with load holding valves and extension and retraction cables. The max. boom length is 27.2 m (89.3 ft). The swing is a gear motor driving a planetary gear reducer with a shaft-mounted pinion, external gear shear ball slew bearing bolted to the superstructure and the car body allows the superstructure to rotate 360°.

Standard is a load moment indicator and anti-two block system with graphic displays and audio-visual warning and control lever lockout. It provides an electronic display of boom angle, length, radius, tip height, relative load moment, max. Permissible laid, load indication, and warning of impending two-block condition. The GTC telescopic boom crawler cranes series come with OPTI-WIDTH, an asymmetrical track positioning system which gives the crane significant lifting capacity enhancements when compared to those for symmetrical tracks.

The frame is an all-steel, welded structure, precision machined to accept attachment of the boom and swing components. Two welded steel side frames are paired with a track group. The side frames extend and retract hydraulically and are controlled from the cab. Equipped with a turbocharged Cummins QSB4.5 engine, this crane is dependable and long-lasting. The GTC-350 has a main winch and (optional) auxiliary winch, with a planetary geared single-speed winch that includes a hydraulic motor, multidisc internal brake, and counterbalance valve. A drum rotation indicator is included.

The hydraulic system uses a hydraulic pump, one high pressure, variable axial piston pump with load sense, and power limiting control for crane functions. One gear pump for cooling function

The operator’s cab is a fully-enclosed, air-conditioned all-steel modular cab with a lockable swinging door, acoustical lining, anti-slip floor, and tinted safety glass. Rearview cameras are appropriately located as are three remote control work lights. There is a two-way armrest mounted hydraulic joysticks control swing, main winch, auxiliary winch. and boom hoist. Hydraulic foot pedals control the travel, boom extends, and swing service brake functions.
