1. What is a folding straddle carrier?

A folding straddle carrier is a heavy‑duty, self‑propelled lifting machine that “straddles” its load (typically containers or oversized cargo) and can be width‑wise folded to a much smaller footprint. This unique design allows the entire unit to be shipped inside a standard ISO container without disassembly.

2. How does the folding mechanism work?

The main frame is hydraulically retracted or collapsed on both sides, reducing the overall width. At the same time, the lifting legs can be lowered to a transport height. The operation is controlled via the PLC system and takes only a short time, requiring no special tools.

3. Can the machine be transported in a standard shipping container?

Yes. When fully folded, the straddle carrier fits inside a standard 20‑foot or 40‑foot ISO container (depending on the model). This eliminates the high cost and long downtime of dismantling and reassembling conventional straddle carriers for overseas relocation.

PRODUCT INTRODUCTION

Folding Straddle Carrier is an innovative rubber-tired container handling machine engineered with a patented hydraulically foldable gantry frame. Unlike conventional straddle carriers with a fixed-height portal, this machine can significantly reduce its overall height by folding the upper frame structure, enabling seamless passage through low doorways, warehouse entrances, tunnels, and under overhead obstacles.

The folding mechanism is operated by heavy-duty hydraulic cylinders with automatic locking pins, ensuring structural rigidity during lifting while allowing rapid height transition in under 60 seconds. This makes the machine ideal for facilities with mixed indoor–outdoor workflows, low-clearance depots, and sites requiring frequent relocation via public road transport.

APPLICATION

1.Ports & Container Terminals
Container stacking (typically 3‑high to 5‑high, and sometimes up to 6‑high), horizontal transport between quay and yard, and vessel discharge/receiving operations. The machine can handle 20ft, 40ft, and 45ft ISO containers using telescopic spreaders with twist locks. It also supports rapid turnaround of feeder vessels and barge operations in busy ports.

2.Intermodal Logistics & Depots
Efficient transfer of containers between warehouses, depots, and main yards, particularly valuable for facilities with space constraints or those requiring flexible equipment deployment. It streamlines railhead-to-yard movements and supports cross‑dock operations where multiple transport modes converge.

3.Industrial & Civil Engineering Projects
Movement of heavy precast concrete elements (e.g., beams, columns, panels), structural steel components, and other oversized loads on construction sites and assembly yards. It also handles tunnel segments, bridge girders, and modular building units with precision.

4.Renewable Energy & Nuclear Sector
Handling of heavy and high‑value components such as wind turbine nacelles, tower sections, transformer modules, and reactor components in power plant construction and maintenance. The folding design enables easy site‑to‑site relocation as projects progress.

FEATURES

The machine can be hydraulically folded or retracted widthwise, reducing its overall width for transport or storage. When folded, the entire unit fits inside a standard ISO container, enabling cost-effective global shipping without dismantling.

Telescopic legs allow the machine height to be varied even with a suspended load, enabling passage through warehouse doorways and providing alternative/additional lifting stroke.

A telescopic transverse beam allows the track width to be adjusted to adapt to different quay widths, pass through building entrances, and optimize parking space.

Multi-mode steering capabilities, including crab steering for precise positioning in confined spaces. Service braking + emergency braking with controlled deceleration.
