Introduction

Application Scenario

Advantages

Structural Diagram And Parameter Table

INTRODUCTION

A Mini Portable Gantry Crane is a compact, lightweight, and highly adaptable lifting device designed to bridge the gap between heavy, fixed crane systems (like overhead or large gantry cranes) and manual lifting. Built with high-strength carbon steel or aerospace-grade aluminum alloy, it features universal swivel casters with brakes at the base, eliminating the need for dedicated floor rails or structural building modifications.

APPLICATION SCENARIO

  • Machinery & Workshops: Precision CNC mold loading/unloading, plus heavy motor, gearbox, and equipment overhaul.

  • Auto Repair & Service: Safe lifting of engines, transmissions, and heavy chassis components in vehicle bays.

  • Warehousing & Logistics: Loading, unloading, and stacking heavy crates or steel in facilities without overhead bridge cranes.

  • Cleanrooms & Pharma (Aluminum): Contamination-free, rust-proof equipment maintenance in pharmaceutical, food, or lab environments.


ADVANTAGES

  • Adjustable Height & Span: Telescoping support legs enable height adjustments to clear low doorways, basements, or tight mezzanine ceilings.

  • High Cost-Efficiency (ROI): Eliminates the expensive civil engineering, steel runway installations, and plant structural permits associated with permanent bridge cranes.

  • Extreme Portability & Rapid Assembly: Modular design allows 1–2 operators to assemble or dismantle the structure using simple bolt connections in 10–15 minutes, making it easy to store or transport in standard commercial vehicles.
