Hydraulic Gantry Crane For Sale

Product Description

Hydraulic gantry cranes are specifically designed for lifting and handling various types of industrial equipment, suitable for the assembly and disassembly of large-tonnage equipment or overweight cargo during movement. A hydraulic gantry crane consists of a complete structural gantry frame, traveling mechanism, lifting mechanism, hydraulic control system, electrical control system, power supply system, and safety protection devices.

Featuring a fully hydraulic drive, it is suitable for various locations without power supply, with its own power system, offering strong adaptability and flexible maneuverability.

We specialize in the research and production of high-performance hydraulic gantry cranes, suitable for high-precision lifting, lateral movement, positioning, and heavy-duty handling and installation tasks of large equipment.

Hydraulic Gantry Crane Components

• Gantry Structure:  A box-type or truss structure spanning the work area, serving as the main load-bearing component of the crane. The legs connect the main beam to the lower support structure, supporting the entire crane and transferring the load to the ground.
• Lifting Mechanism: A hydraulic motor acts as the power source, converting hydraulic energy into mechanical energy. Large-tonnage cranes often use low-speed, high-torque hydraulic motors to directly drive the drum. The counterbalance valve is a key hydraulic component, preventing uncontrolled descent (stalling) of heavy loads, providing safety braking and precise control.
• Traveling Mechanism: Responsible for the movement of the entire crane and the trolley. The main traveling mechanism moves the entire gantry along the track longitudinally. The trolley traveling mechanism moves the lifting trolley laterally along the main beam track.
• Hydraulic System: The core power and control system of the hydraulic gantry crane. It includes a hydraulic power unit and a control valve group. The hydraulic power unit acts as the power source, including the prime mover (diesel engine or electric motor), hydraulic pump, and oil tank. The control valve group consists of multi-way directional control valves, relief valves, throttle valves, etc., used to control the direction, speed, and pressure of each mechanism's operation.
• Electrical Control System: Includes the control panel, sensors, PLC, and safety protection modules. These components work together to process operating commands and coordinate the actions of each mechanism.
• Safety Protection Devices: Including overload limiters, travel limit switches, buffers and anti-collision devices, and hydraulic system safety valves. These components work together to ensure the safe and efficient lifting and handling of various heavy objects by the hydraulic gantry crane.

Working Principle

Features and Advantages

Compact and Flexible Design:
We adopt a modular design to build a compact structure with a small footprint. This makes the crane easy to transport, install, and disassemble, ideal for tight workspaces.

Adjustable Columns:
Our crane features telescopic columns. You can adjust the height flexibly to match lifting needs, which helps in low-ceiling or height-restricted environments.

Diverse Travel Modes:
It supports rail-mounted movement for linear operation, or trackless self-propelled travel for flexible positioning. You can also add a self-propelled chassis for greater mobility.

Smooth and Precise Operation:
The crane offers stepless speed control for smooth lifting and moving with very little impact. We achieve high-precision synchronization through electronic proportional control, hydraulic sync valves, or PLC systems, delivering millimeter-level control.

Intelligent and Convenient Controls:
An integrated electro-hydraulic control system supports wireless remote and micro-motion control. The simple, intuitive operation reduces operator effort.

Multiple Safety Protections:
Our hydraulic system includes overload protection. We also integrate electrical safety features such as lifting height limits, travel limits, and emergency braking to ensure reliable operation.

Simple and Economical Maintenance:
We use highly standardized, interchangeable hydraulic parts. The independent system and straightforward piping simplify maintenance and help lower long-term operating costs.

Application Scenarios

• Metallurgical Industry: Ladle transfer, lifting of steel billets/slabs, installation and maintenance of large-scale production line equipment such as rolling mills.
• Power Industry: Installation, relocation, and maintenance of large power equipment such as generator stators/rotors, transformers, and gas turbines.
• Large-scale Civil Engineering: Assembly and disassembly of heavy components such as tunnel boring machine (TBM) parts, large formwork, and building steel structures.
• Precast Component Manufacturing: Demolding, stacking, and loading/transportation of large precast concrete components (such as PC components and pipe galleries).
• Paper and Building Materials Industry: Installation and maintenance of core production equipment such as large rollers, drying drums, and presses.
• Port Terminals and Warehousing Logistics: Loading, unloading, stacking, and short-distance transportation of containers, bulk cargo, heavy goods, and large materials.
• Emergency Rescue: Used as temporary heavy lifting equipment for clearing large obstacles after disasters or for emergency repair of critical equipment.
• Shipbuilding and Ship Repair: Hull section joining, superstructure lifting, installation of large equipment such as main engines/steering gears, ship launching, and dry dock repair operations.
