18.5m High Altitude Roll Forming Machine with 8-Ton Lifting Capacity and Wireless Remote Control Crawler Platform

When a steel structure warehouse or factory building reaches 12–18 meters in roof height, contractors face a familiar bottleneck: finished roof panels must be lifted by crane, hoisted to the roof edge, and then manually passed along trusses — a process that wastes 2–3 hours per panel stack, risks damaging the pre-painted surface, and introduces fall hazards. The Howann 18.5m crawler high altitude roll forming machine solves this by bringing the roll former itself to the roofline: raw coil is fed at ground level, the machine continuously forms color steel, galvanized or aluminized-manganese panels on an 8m working platform, and finished tiles exit directly at the installation height.

This is not a standard aerial work platform with a roll former bolted on. Howann engineers engineered the entire unit around the Komatsu PC100 crawler chassis geometry, a 1800mm heavy-duty slewing bearing rated for 80-ton rotation load, and 700L crane-boom-grade steel plate throughout the main boom and outriggers. The platform carries 8 tons including the tile press, accommodates operators plus material feed, and reaches a maximum tile outlet height of 18.5 meters — covering the vast majority of single-story industrial steel structures, logistics warehouses, and large-span agricultural buildings commonly built across Southeast Asia, the Middle East, Africa, and South America.

Every unit is manufactured under the Special Equipment Manufacturing License issued by the State Administration for Market Regulation, and each machine ships with an inspection report and test certificate from the National Testing Center — documents that contractors in Saudi Arabia, Australia, and the EU frequently require before equipment enters a certified job site.

Why Contractors Choose This Over Crane-Lifted Panels

Job-site experience across hundreds of steel structure projects shows that a single 18.5m crawler roll forming platform replaces three separate work streams: the crane lift crew, the roof-edge receiving crew, and the panel splicing crew. Because the tile exits the former directly at the eave or ridge line, installers walk panels into position without wrestling them over purlins. Panel output length can run continuously from 1 meter up to 200 meters, meaning a 100-meter warehouse roof can be produced in one continuous panel run with zero longitudinal overlap — eliminating the most common leak point in metal roofing.

The tile output radius of ≤6000mm means the platform slews left and right to cover the roof bay without repositioning the crawler, while the optional reverse ceiling platform (8m × 12m) lets crews install ceiling and wall panels simultaneously from the same unit. For large projects, the optional 3-, 5-, or 8-ton onboard crane handles coil changes and material transport at height, removing the need for a second mobile crane on site.

Hydraulic Safety System

The outrigger and main boom cylinders are the safety-critical components. Howann specifies quenched 42CrMo (oil drill pipe material) piston rods and imported Huntsman seals from the USA — a combination that field feedback shows extends seal service life by roughly 30% and increases structural strength by about 1.3 times compared with industry-standard cylinders. The outrigger cylinders use a 135mm outer diameter / 90mm rod (container version) or 160mm / 115mm rod (standard version); main boom cylinders use 160mm / 115mm or 180mm / 180mm rods. Four-layer steel wire Class 1 explosion-proof hydraulic hoses from Nitto Hydraulic and seamless steel tubes manufactured in Wuxi complete the circuit. Two 7.5kW ultra-large-flow Sunny hydraulic pumps handle lifting and cutting independently, so a hydraulic shear jam never interrupts the lifting function.

Steel Structure and Load Path

All profile steel and boom plates are 700L material — the same grade used in truck crane booms, roughly one-third stronger than conventional Q355 structural steel, with a safety factor improvement of over 30% against bending fatigue. Howann cuts these plates on dedicated laser lines and welds them on a profile welding production line with subsequent calibration. The 1800mm diameter heavy-duty slewing bearing from Luoyang Bearing — a Chinese manufacturer with over 60 years in large-diameter bearing production — carries the 80-ton rotation load that accumulates from boom weight, platform load, and outrigger reaction forces. Shafts are precision-ground 45# steel, quenched and chrome-plated.

Electrical and Operator Control

The control cabinet uses a stainless steel enclosure with a Mitsubishi PLC (Japan), Schneider electrical components, and a 18.5kW inverter. A second screen and distribution box sits on the platform itself, so operators can control from ground level or from the working platform. The height and angle controller displays real-time elevation and slew angle, with restriction and alarm functions for improper operation; an optional platform weighing function triggers overload alarms and locks out lifting actions. The full-vehicle remote control uses an imported chip, so outrigger extension, platform lifting, travel, and steering are all radio-controlled — eliminating the traditional multi-person hand-signal crew that typically surrounds a lift machine. A 24V low-voltage solenoid valve system from Beijing Huade ensures durability in dust and humidity.

The oil-electric dual lifting system is a practical energy feature: on-site, the engine drives the hydraulic system for travel and setup, but once positioned, crews can switch to 380V / 50Hz electric power (two 7.5kW pumps) for quiet, emission-free lifting and forming — a meaningful advantage on urban projects where nighttime work restrictions apply.

FAQ

Q: How does this compare to lifting finished panels with a mobile crane? A: Field experience shows crane-lifting requires a dedicated crane for 3–5 days on a typical warehouse project, plus a roof-edge receiving crew and a ground routing crew. The crawler roll former produces panels on site, eliminates the crane dependency, and can deliver continuous single-run panels up to 200m without longitudinal overlaps — the number-one leak point in metal roofing.

Q: Can it work on unfinished gravel or dirt sites? A: The 500mm crawler tracks and 45-ton traction chain are designed for that. The 105 HP turbocharged diesel climbs typical construction-site grades, and the outriggers level the machine on uneven ground via remote control.

Q: What roll forming machines fit on the platform? A: The platform accommodates Howann's full Jiaochi series roof and wall panel forming machines with motor-reducer drive and hydraulic shearing. The electrical and hydraulic quick-connects between platform and tile press are standardized, so customers running existing Howann formers can mount them on this lifting platform without modification.

Q: Is electric lifting really usable on site? A: Yes — the oil-electric dual system lets crews switch from diesel to 380V electric once the machine is set up and plugged in. This reduces noise and engine hours during long production runs, which matters on urban projects with nighttime work restrictions.
