This Rubber-Tired Gantry (RTG) Crane is designed for flexible container transshipment, moving on high-quality, wear-resistant rubber tires with a protective device for easy turning. It features a drag trolley design, resulting in a lightweight structure, advanced performance, high efficiency, excellent maneuverability, and minimal sensitivity to ground unevenness.

Power & Mobility:
The crane is primarily powered via a cable drum. For maximum operational continuity, it is also equipped with a diesel generator set, enabling use during power outages or when relocating between yards.

Structure & Composition:
The RTG consists of a bridge, support legs, a crane traveling mechanism, a trolley, electrical equipment, and a heavy-duty lifting winch. The frame utilizes a robust box-type welded structure. The traveling mechanism employs a separate drive system, and all operations are controlled from the driver's cabin. Power can be supplied by cable or sliding wire. Various capacity models are available to suit specific application needs.

Key Components & Control:

Lifting Trolley: Incorporates a hoist mechanism designed for high working duty.

Control System: Utilizes Schneider variable frequency speed regulation and a Siemens PLC control system, equipped with remote monitoring (RCMS) and operation capabilities.

Container Spreader: A high-precision spreader suitable for handling international standard containers (twin-lift spreader available on request).
