Portable Gantry Cranes-Heavy Duty Transfer Cart & AGV/RGV Systems

The mobile gantry crane is a modular, mobile, lightweight gantry crane consisting of a high-strength steel frame, I-beam main beams, and braked swivel casters. Its bolt-assembled structure allows for quick on-site assembly and disassembly without the need for a fixed foundation. The lifting height and span are adjustable to suit different workspaces.

It can be used with electric chain hoists, wire rope hoists, or manual chain hoists for lifting operations. Equipped with locking casters, it can move freely on flat ground, enabling multi-station operation. With its compact structure, flexible movement, low cost, and reliable safety, the machine is widely used in workshops, warehouses, repair shops, and garages for temporary lifting operations such as equipment assembly, mold handling, and loading/unloading. Multiple tonnage options and customized manufacturing are available.

Dual Adjustment of Height and Span: A multi-level pin positioning system flexibly adapts to warehouses and operating spans of varying heights.

Modular and Detachable Design: The entire machine is bolted together, requiring no welding, facilitating modular transport and cross-site transfer.

All-Around Translation and Steering: Equipped with four sets of heavy-duty, braked swivel casters, supporting precise small-range movement even under full load.

High-Strength Steel Structure Beams: Utilizing reinforced I-beams, ensuring minimal deflection under large-span loads.

Hydraulic Assisted Lifting: Optional hydraulic rocker arm control for column lifting allows for easy height adjustment even with a single operator.

Anti-Sway Bracing Structure: Reinforced diagonal braces between the column and beams greatly enhance lateral stability during operation.

Machine tool centers are used for the installation of machine tool parts and the loading and unloading of components.

Automobile repair centers are used for the overall hoisting of core components such as engines and transmissions.

Precision instruments and experimental cabinets are handled delicately in laboratories and cleanrooms.

Temporary lifting areas in warehouses are used for loading and unloading bulk goods using electric hoists.

In mold warehouses, injection molds are transferred horizontally and aligned on storage racks.

Temporary outdoor repair areas provide rapid assembly and single-point lifting support.
