20 ton gantry cranes are widely used in material handling applications such as factory workshops, warehouses, construction sites, ports and railway freight yards.
20-ton gantry cranes are widely used in material handling applications such as factory floors, warehouses , construction sites, ports, and railway freight yards . 20-ton gantry cranes offer a variety of structural designs, adapting to most material handling scenarios. If you have specific needs, Nucleon also offers a range of customized services to meet your requirements.
The sturdy and durable 20-ton gantry crane is composed of a variety of accessories, which have different functions and each accessory is indispensable.
The most critical lifting component of a 20-ton crane. Use the hook to pick up and place loads, and the hinge and steel rope to adjust the height of the material.
The horizontal moving part can slide along the main beam track. Its main function is to drive the electric hoist to adjust its horizontal position and expand the coverage of materials.
Gantry crane controllers are generally divided into wireless remote controls and cab controls. The wireless remote control allows for remote automated operation of a 20-ton crane, making it safer and more efficient. Technicians can also perform more complex and specialized equipment operations from within the cab.
Safety devices include limiters to prevent the crane and trolley from exceeding their travel range, brakes for emergency stop, and overload sensors to prevent overloading . All safety devices comply with relevant standards to prevent accidents from occurring or escalating.
According to different structural designs and application scenarios, 20-ton gantry cranes are mainly divided into the following types:
Structural features : single main beam + electric hoist trolley, simple structure , light weight and small footprint.
Gama de alcance : 27 meters; lifting height: 9-12 meters
Cenários aplicáveis : Suitable for medium and light load operations in workshops, warehouses, small docks , etc.
Core advantages : low cost, easy installation, small footprint
Structural features : Double main beams + trolley with hook/electric hoist, strong rigidity and good stability.
Gama de alcance : 28 meters; lifting height: 6-20 meters
Cenários aplicáveis : Suitable for large factories, ports, construction sites
Core advantages : strong carrying capacity, adaptable to high-frequency operations . Can be equipped with auxiliary hooks to achieve double-load operations.
Structural features : One side has legs (running along the ground track), the other side relies on the building wall (running along the elevated track)
Gama de alcance : 12-25 meters; lifting height: 6-15 meters
Cenários aplicáveis : small warehouses, factory assembly lines
Core advantages : Saves ground space; suitable for working along building walls.
Structural features : removable main beam + rubber tire (no need for fixed track)
Gama de alcance : 8-18 meters; lifting height: 5-10 meters
Cenários aplicáveis : temporary lifting operations such as construction sites, maintenance workshops, and outdoor cargo yards
Core advantage : Fast movement speed, can quickly change positions in the work environment.
Structural features : The main beam adopts a truss structure (welded from steel sections into triangular/trapezoidal trusses), and the legs are mostly lattice-shaped designs.
Gama de alcance : 15-35 meters; lifting height: 8-22 meters
Cenários aplicáveis : Suitable for windy scenarios, such as ports, coastal mines , etc.
Core advantages : The truss structure is light in weight , quick to install, has low wind resistance, and is suitable for outdoor operations.
Structural features : The outriggers are arranged in an L-shaped pattern, with one end of the main beam connected vertically to the L-shaped outriggers, and the other end extending to the edge of the working area (without outrigger obstruction).
Gama de alcance : 27 meters ; lifting height : 8-16 meters
Cenários aplicáveis : used for transporting long strips of materials or large-volume goods .
Core advantage : The special gantry structure can ensure the passage space of goods and also reduce the deadweight of the 20-ton gantry crane.
