The TD120TN TrackDrive (sometimes called a spider lift) offers an impressive working envelope from a compact, crawler-mounted base that uses continuous tracks for outstanding traction.
Combining the benefits of continuous track propulsion with hydraulically-operated outriggers, it can be positioned, set up and operated from the cage, even on slopes, saving time and improving efficiency.
The TD120TN’s compact dimensions and low overall-weight, make it ideal for working in a wide range of environments, but its unique feature is retractable tracks, which allow it to pass through a 0.8m opening for restricted access applications.
When stowed, it can be driven from one location to the next, using a detachable cage control console, for increased operator comfort and field of vision.
Continuous tracks deliver supreme grip and 60% gradeability, which together with its ability to turn on the spot, make moving the machine from one location to the next easy, even over extreme gradients.
It’s particularly effective in outdoor locations with slopes or soft ground surfaces, but rubber-free urethane 'non-marking' tracks are also available, allowing it to work internally, maximising its versatility.
When working at height, fully-proportional controls deliver smooth, measured operation while a telescopic upper boom allows for precise positioning anywhere in its impressive working envelope.
Weight-saving design means that site-to-site transportation is more economical and the TD120TN is also more efficient, allowing it to work for longer while using less fuel.
