Product Overview
The Howann crawler-mounted roof tile roll forming machine is a mobile on-site roof production system: a roll former sits on a hydraulic lifting platform mounted on a crawler chassis, producing color steel, galvanized, or aluminized-manganese roof panels directly at eave height — no crane, no panel lifting, no roof-edge handling. Raw coil feeds at ground level, the platform rises to 5–18 meters, and finished panels exit continuously up to 200 meters long.
This version is engineered for export shipping: the container variant retracts to a 2.28m width and 12m length, fitting a standard shipping container with minimal disassembly. A bulk-carrier variant (2.95m width, ~24T) is available for customers without container access. The 50-ton traction crawler and 110/150 HP turbocharged diesel engine move the machine over unfinished gravel and mud sites, while the 8m * 2.3m work platform supports crew, coil stock, and the tile press itself.
Every unit is manufactured under the Special Equipment Manufacturing License (State Administration for Market Regulation) and ships with a National Testing Center inspection report and test certificate — standard documentation for contractors in Australia, the Middle East, Southeast Asia, and Africa.
Why Contractors Specify This Machine
On a typical 10,000 m² logistics warehouse, crane-lifting pre-rolled panels costs roughly 3–5 crane-days plus a roof-edge receiving crew. The Howann mobile system produces panels at the roofline in one continuous run up to 200m, eliminating longitudinal overlaps — the number-one leak point in metal roofing. The platform slews to a 6m radius, covering an entire roof bay before the crawler repositiones. The optional reverse ceiling platform (8m * 12m) lets a second crew install underside panels simultaneously.
The oil-electric dual lifting system is a practical export feature: the diesel engine drives travel and setup, then crews switch to 380V / 50Hz electric power (two 7.5kW pumps) for quiet production runs — meaningful on urban projects with nighttime noise limits.

On-Site Workflow
- Container shipping: Unit retracts to 2.28m width, loads directly into a standard container with the roll former mounted.
- Site setup: Crawl to position, extend four outriggers to a 5.3m * 5.3m footprint, level via remote (optional automatic one-button leveling).
- Coil feed: Raw coil loaded at ground level; optional onboard crane handles coil changes without a separate mobile crane.
- Produce: Raise platform to working height, run the tile press, output continuous panels up to 200m directly at roof level.
- Relocate: Retract outriggers, drive along the building length, reposition — all without crane assistance.
Application Scenarios
- Large-span steel structures: Logistics warehouses, e-commerce sorting centers, factory plants with 8–18m eave heights
- Agricultural & livestock buildings: Poultry houses, grain sheds, dairy barns requiring long continuous panels
- Municipal & commercial: Stadiums, exhibition halls, metro depots where crane time is costly
- Remote & site-constrained projects: Mines, plant expansions, and re-roofing jobs where crane access is limited
Certifications & Support
- Special Equipment Manufacturing License — State Administration for Market Regulation

FAQ
Q: Can the machine fit into a standard shipping container? A: Yes. The container variant retracts to 2.28m width and 12m length, designed for standard container loading. The bulk-carrier variant (2.95m width, ~24T) is for customers shipping as breakbulk.
Q: What tile press models are compatible? A: The platform accommodates the full Howann Jiaochi series roof and wall panel forming machines with motor-reducer drive and hydraulic shearing. Electrical and hydraulic quick-connects are standardized.
Q: How does the oil-electric dual system benefit export customers? A: The diesel engine powers travel and setup on sites without grid power. Once positioned near a 380V supply, operators switch to electric lifting for quieter, lower-cost production and reduced engine wear.
Q: What is the lifting height range for roof output? A: The tile outlet reaches from 5m to 18.5m, covering most single-story industrial steel structures. Ceiling panel installation can reach up to 19.5m including operator height.
