Retractable Roof Tarpaulin System

Retractable Roof Tarpaulin System

The Retractable Roof Tarpaulin System is a precision-engineered sliding roof solution designed to provide complete overhead coverage for platform, curtain-sider, and open-top trailer bodies suitable for harsh weather conditions.

By enabling the entire roof tarpaulin to be slid fore or aft along a rectangular profile rail, the system allows rapid full-length access to the cargo area from above, facilitating crane loading, top-fill operations, and overhead pick-and-place logistics without any need to disturb side curtains or remove loose covers.

The system is built around a frame of roof bow carriages riding on precision vertical guide rollers, which deliver smooth, low-effort operation across the full length of the trailer body.

The tarpaulin is fabricated from MEHLER Texnologies POLYMAR® PVC-coated polyester tarpaulin compliant with IS 14597 standards, one of the most trusted technical textile brands in the commercial vehicle industry, ensuring exceptional durability, weather resistance, and long service life under continuous high-cycle conditions.

This retractable roof solution eliminates the hazards and delays associated with manually rigging loose tarpaulins, reduces the physical effort required from drivers and loading personnel, and significantly improves throughput at loading bays and distribution hubs.

Key Highlights:

  • Full-length overhead access by sliding entire tarpaulin to the front bulkhead
  • Smooth, low-effort operation via vertical precision guide rollers
  • MEHLER Texnologies POLYMAR® PVC-coated tarpaulin — high tensile strength and UV stability
  • Automatic elevation at front prevents bow carriage interference with bulkhead
  • Corrosion-resistant GI Rectangular profile rail with minimalistic design approach and vertical supporting roller assembly for smooth operation and long service life
  • Fully compatible with crane-loading and side-curtain trailer body configurations
  • Modular spare parts design for rapid in-field servicing
