Telescopic Boom LiftT-3000

A telescopic boom lift works on a straight boom made up of nested sections that extend and retract hydraulically, rather than the multi-jointed arm of an articulating boom. That straight-line construction is what lets the T-3000 put its cage exactly on line, at height and at outreach, in a single hydraulic motion — well suited to jobs that need reach straight up and out over a distance, rather than the ability to flex around an obstacle the way an articulating boom can. The boom itself is a high-tensile steel (min. YST 700 N/mm2) box section with plasma/laser-cut profiles and self-lubricating pivot points, driven by double-acting hydraulic rams with induction-hardened, chrome-plated rods. Four hydraulically operated stabilizers, each fitted with lock valves, level and anchor the vehicle before the boom is allowed to move at all — a boom-stabilizer interlock keeps the boom from operating until the stabilizers are fully extended. Slewing is 360-degree continuous via a worm-reduction slew bearing, and the whole machine is EN280-rated, with an insulated bucket option available up to 3kV for work near live electrical lines.

The T-3000 is built on a 12-ton GVW truck chassis with a 4200mm wheelbase. It reaches a 30m working height with a 28m platform (cage floor) height and a 10m maximum horizontal outreach, slewing a full 360 degrees continuously, with a 200kg safe working load. The aluminum operator cage measures 1200 x 1100 x 800mm, with non-slip flooring, drain holes, an onboard tool box, a working light, an emergency switch, and safety hooks, and is operated from a wireless remote at the cage in addition to the switch control panel at base and independent stabilizer controls at the chassis deck. Four hydraulic stabilizers with lock valves level the vehicle before the boom operates, backed by a single-push-button automatic vehicle leveling system. Safety systems include PLC-based electronic interlocking, a digital safe load indicator, an emergency hand pump for pump/engine failure, over-center valves on the boom cylinders, a max-pressure valve and flow restrictor on the hydraulic circuit, a spirit level indicator, and a slew restriction when the boom is in its cradle support.
