Kershaw® SkyTrim Mini 55 TH

 

Progress Rail’s Maintenance-of-Way (MOW) division was born out of the movement toward mechanization in the railroad industry and introduced the first Kershaw® Ballast Regulator in 1945.

Today, Progress Rail supplies Kershaw® MOW equipment, providing machines to all Class I railroads, transit and short lines and contractors around the world.

The SkyTrim mini 55 TH is a compact, mobile, self- powered tree trimmer based on a telehandler platform.

The SkyTrim mini 55 TH is ideal for residential applications, golf courses, rental properties, and municipalities. 

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 m). 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 27 degrees of movement which allows the boom and saw blade 25 feet 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 with tinted glass and external screen guards with optional beacon and light kits.
