Kershaw’s 55-foot,1-stage insulated telescopic boom is mounted to a Cat® TH255 Telehandler base for markets within North America.
The SkyTrim mini is a compact single operator self-contained tree trimming machine based on a telehandler. The upper unit is a two stage insulated telescopic boom equipped with a single large saw blade with a cutting height of 55 feet (17 Metres). The saw is capable of rotating on its own axis (185 degrees) providing for accurate cutting of tree limbs at any angle. The entire boom assembly pivots on a slewing ring providing 12 degrees of movement which allows the boom and saw blade 10 ft of side to side movement at the blade tip, allowing for extreme cutting accuracy without repositioning the entire machine. The upper tree trimmer is mounted on a telescopic handler base machine equipped with the latest tier 4 engine, 4 wheel steer and crab steer providing a highly maneuverable stable machine package. The chassis is fitted with outriggers for trimming on slight inclines. The operator cab is EROPS certified, air conditioned and comes fitted with radio, tinted glass and external screen guards with beacon and light kits.
