135ft Boom Lift

  The STJ410N is a robust self‑propelled diesel‑driven mobile elevating work platform engineered for ultra‑high‑reach operations within heavy‑industry environments. Delivering a maximum working height of 41 meters (135 ft), this unit is purpose‑built to handle demanding high‑elevation assignments, ranging from ship repair and hull surface treatment to large‑venue erection and high‑rise building renovation. Powered by a Cummins B3.9 diesel power unit that puts out 59 kW at 2500 rpm, the machine ensures consistent output under heavy‑load site conditions. Its main boom covers a luffing range from ‑11° up to 70°, paired with unrestricted 360‑degree continuous turret rotation. The operator basket delivers ±90° horizontal swing, with a safe working payload of 250 kg for personnel and job‑site tools. Equipped with heavy‑duty off‑road tyres and a 25‑percent gradeability rating, it easily navigates uneven, gravel‑strewn ground typical of dockyards and construction zones. Common deployment scenarios cover ship‑repair facilities, high‑rise facade refurbishment, sports arena assembly, overhead plant equipment servicing and complex bridge‑related elevated works.

Reliable powertrain for extended site shifts

Backed by the proven Cummins B3.9 diesel engine, this boom lift maintains steady torque output during prolonged heavy-duty operation. A large-capacity 230-litre fuel reservoir cuts down frequent refuelling stops, maximising on-site uptime and overall job-site productivity.

Versatile multi-position access for tricky elevated spots

Wide-range boom luffing motion combines with full 360° turret rotation and ±90° platform swing. Operators can position the basket precisely onto awkward, hard-to-reach work surfaces without repeated machine repositioning, streamlining workflows across complex-structure sites.

Superior off-site travelling capability

Featuring 25% gradeability, 12.00-20 heavy-load tyres plus 290 mm ground clearance, the unit travels confidently over rough, undulating and gravel-covered terrain. Reinforced undercarriage structural design preserves overall machine stability even with the boom fully extended at maximum outreach.

Multi-layered safety protection system

Refined hydraulic control logic works alongside a complete suite of built-in safety interlock assemblies to mitigate operational risks. A substantial 22500 kg operating mass delivers solid base stability, even when working at peak height and maximum horizontal extension.
