Hydraulic Gantry Crane

Product Description

The Nucleon Hydraulic Gantry Crane is a self-propelled, modular heavy-duty hydraulic lifting system designed specifically for the most demanding industrial lifting operations. Developed and manufactured by Nucleon Crane—a group boasting over 20 years of experience in heavy lifting equipment manufacturing—it stands as one of China's leading crane manufacturers, offering products with rated lifting capacities ranging from 50 to 1,000 tons.

Unlike traditional overhead or gantry cranes, the hydraulic gantry crane operates on ground-level rails or rubber-tired locomotion systems; as it does not rely on fixed building structures, it offers flexible deployment options for outdoor yards, large-scale workshops, and construction sites. Its PLC-controlled synchronized hydraulic cylinder system enables smooth lifting with millimeter-level precision—a capability that is particularly critical for the hoisting of precision equipment and oversized cargo.

Each hydraulic gantry crane is custom-designed to meet specific client requirements and strictly adheres to international certification standards, including FEM 1.001, ISO 9001, EN 13001, and CE. Consequently, it serves as a reliable choice for heavy engineering projects such as the handling of nuclear power equipment, the installation of heavy machinery, and the hoisting of large-scale steel structures.

Core Components

The Nucleon Hydraulic Gantry Crane consists of eight major precision-engineered subsystems:

Hydraulic Power Unit (HPU): A high-pressure hydraulic pump station—equipped with redundant relief valves, servo-controlled flow regulation, and an integrated cooling system—provides stable power for the entire machine's lifting and travel functions.
Main Frame and Gantry Legs: Heavy-duty welded steel leg structures featuring high-strength bolted splice joints. The modular design allows for transport within standard shipping containers and enables rapid on-site assembly without the need for welding.
Hydraulic Lifting Cylinders: Synchronized telescopic hydraulic cylinders, equipped with stroke encoders for real-time position feedback, ensure multi-point lifting synchronization accuracy within ±1 mm, effectively preventing load tilting.
Self-Propelled Tire Transporters / Rail-Mounted Dollies: Self-propelled rubber-tired transporters or rail-mounted dollies, featuring independent steering systems, support various movement modes including lateral travel, curved travel, on-the-spot turning, and 360° rotation.
PLC Main Control System: Features a Siemens or Schneider PLC main controller, equipped with a wireless handheld remote and an HMI touchscreen display. It provides real-time monitoring of load weight, tilt angle, and travel status, while incorporating built-in fault diagnostics and anti-tipping protection functions.
Beam and Spreader Extension Devices: Custom-engineered extension beams or lifting beams, tailored to the specific geometry of the load. Designed in accordance with FEM and ASME BTH-1 standards, these components ensure structural integrity under full-load operating conditions.
Load Monitoring System: Integrated load sensors are installed at every lifting point, featuring overload alarms and automatic power-cutoff protection. Optional upgrades for data logging and remote monitoring capabilities are available.
Safety Limit Devices: Comprising upper and lower travel limit switches, anti-collision sensors, emergency stop circuits, and hydraulic locking valves, this comprehensive system ensures safe operations across all working conditions.

Core Advantages

Multi-Point Synchronous Lifting Control

A PLC-controlled synchronous hydraulic system ensures lifting synchronization accuracy of ±1 mm across all lifting points, effectively preventing load skewing and structural stress damage to precision equipment.

Modular Design for Rapid Assembly

The bolt-connected modular frame can be transported within a standard 40-foot shipping container; on-site assembly requires no welding, thereby reducing equipment mobilization and demobilization times by up to 60%.

Omnidirectional Mobility

An independent wheel steering system enables lateral movement, curved travel, on-the-spot rotation, and 360° pivoting, allowing for the effortless maneuvering of oversized loads within confined spaces.

Wireless Remote Control Operation

Operators can control all lifting functions from a safe distance using a handheld wireless remote or a tablet device, while simultaneously monitoring real-time data regarding load weight, tilt angles, and travel status.

Variable Lifting Height

Standard lift stroke up to 1.8m per stage with multiple cylinders stackable for extended heights. Custom lift heights up to 6m and beyond available by engineering request.

Triple-Layer Safety Architecture

Mechanical locking, hydraulic safety valves, and software-level PLC interlocks provide three independent layers of overload and anti-drift protection at all times.

Low Ground Bearing Pressure

Multi-axle carrier designs distribute load over a large footprint, achieving ground pressure as low as 5 kg/cm² — suitable for floor slabs and unprepared outdoor surfaces.

Global Standards Compliance

CE marked, ISO 9001 certified, and designed in accordance with FEM 1.001, EN 13001, and ASME B30.2 standards to meet procurement requirements worldwide.
