Collapsible Metal Ramp

Overview

Collapsible wheelchair ramp designed for safe load transfer and compact storage, with a multi-panel folding structure and full fabrication-ready technical documentation.

Specifications

  • Load Capacity: ~100 kg
  • Structure: 4-panel folding ramp with hinge mechanism
  • Total Length (open): ~36 in
  • Weight: ~79 lb total assembly

Materials

  • Ramp Panels: 7075-T6 Aluminum
  • Rails & Curbs: 6061-T6 Aluminum
  • Hinges & Pins: AISI 304 Stainless Steel
  • Surface: Silicon rubber non-slip layer

Design Approach

The ramp was designed as a modular multi-panel system connected via piano hinges, enabling folding into a compact form while maintaining structural continuity under load.

Cross-support members and side curbs were integrated to improve stiffness and ensure safe wheel guidance during operation.

Key Features

  • Multi-panel folding mechanism for compact storage
  • Non-slip surface for safe wheelchair operation
  • Side curbs and rails for wheel alignment and safety
  • Fully detailed BOM and fabrication drawings for manufacturing

Deliverables

  • Complete 2D engineering drawing set (10 sheets)
  • Full BOM with materials and quantities
  • Assembly definition with exploded and folded configurations

Outcome

Delivered a fabrication-ready ramp system combining structural integrity, portability, and user safety, supported by complete technical documentation for manufacturing.
