High Altitude Roll Forming Machine Crawler Aerial Work Platform with 18.5m Lifting Height and 8T Platform Capacity for 12m Telescopic Roof Panel Production

For contractors handling steel structure erection, curtain wall installation, and high-altitude roof panel work, choosing between a truck-mounted boom lift and a rough-terrain crane usually means compromising: truck lifts can't reach unfinished sites, while cranes waste time on positioning and can't hold a stable platform for crew work. The Howann 18.5m crawler aerial work platform fills that gap — it crawls over gravel, mud, and unfinished construction surfaces on 500/600mm track plates, extends a 12m × 3m working platform to 18.5 meters, and carries 8 tons including crew and materials.

Built on a Komatsu PC200 undercarriage with a 70-ton traction chain and a 150 HP turbocharged diesel engine, this is a heavy-duty machine, not a compact spider lift. The platform itself telescopes out to a 12m × 8m outrigger footprint, and the 2100mm double-row ball slewing bearing (French) is rated for a 120-ton rotation load — the same class of component used on mid-size truck cranes. It also supports mounting a roof tile roll former directly on the platform, making it a dual-purpose unit: aerial work platform by day, on-site roof panel factory when needed.

Every unit ships under the Special Equipment Manufacturing License (State Administration for Market Regulation) and carries an inspection report and test certificate from the National Testing Center — documents that general contractors in Australia, the Middle East, and Southeast Asia routinely require before equipment enters a certified work zone.

Field experience on steel structure and logistics warehouse projects shows that a 12m-long platform changes the workflow: instead of repositioning the lift every 3–4 meters along a roof line, crews can work continuously along an entire bay length from one setup. The platform guardrail rises to 1m, and the optional reverse ceiling platform (8m × 12m) lets a second crew install underside ceiling panels simultaneously. The optional 5-ton onboard crane — built on 700BL spec steel with a 3-section 9m boom — handles coil lifting and material hoisting at height without calling a separate mobile crane.

The oil-electric dual lifting system is a practical feature for urban projects: the 150 HP diesel drives travel and setup, but once positioned, crews switch to 380V / 50Hz electric power (two 15kW pumps) for quiet, emission-free operation during long shifts. A dedicated oil tank heating system prevents hydraulic oil from thickening in winter — a detail that matters on projects in northern China, Central Asia, and high-altitude regions where temperatures drop well below freezing.

• Steel structure erection: Column and beam bolting on large-span warehouses and factory plants.
• Curtain wall & façade installation: High-rise cladding, glass curtain wall, and metal panel installation.
• Roof panel production: Mount a Howann roll former on the platform for on-site tile forming up to 18.5m.
• Municipal infrastructure: Stadiums, exhibition centers, metro depots, and bridge maintenance.
• Winter-cold-region projects: Oil tank heating enables reliable operation in sub-zero temperatures.

• Special Equipment Manufacturing License — State Administration for Market Regulation.
• Inspection report and test certificate — National Testing Center.
• 12-month warranty on core hydraulic and electrical components; lifetime technical support and original spare parts supply.
