Telescopic Boom LiftT-1800

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-1800 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-1800 is built on a truck chassis with a 3800mm wheelbase. It reaches an 18m working height with a 16m platform (cage floor) height and a 9m maximum horizontal outreach, slewing a full 360 degrees continuously, with a 200kg safe working load. The FRP operator cage measures 1.0 x 1.06 x 0.76m and is insulated to 600V (tested to 2200V), with non-slip flooring, drain holes, an onboard tool box, a working light, an emergency switch, and safety hooks. Four hydraulic stabilizers with independent control and 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.
