Product Introduction
Gantry cranes or Goliath Cranes are very versatile cranes used typically for activities in steel warehouse, precast yards, construction sites, port, train station, powe plant and other outdoor applications.
Include single girder gantry crane, double girder gantry crane, semi gantry crane, trussed gantry crane. Suitable for indoor and outdoor usage.
These cranes can be completely customized for SWL, span, lifting height, speeds, control method and class of duty to suit the actual applications.
Dafang provide single girder gantry crane solutions from 1 Ton SWL up to 20 Ton SWL (we also manufacture gantry crane designed according to client special requirement).
According to different situations, single girder gantry crane have three type: L single girder gantry crane, MH single girder gantry crane, truss type single girder gantry crane.
Technical Features
- Gantry cranes are more quickly and easily for installed and disassembled, it is ideal choice for use in a rented factory or in multiple work place
- Equipped with all the necessary safety device： overload limit switch, travel limit switch, height limit switch, hook safety latch
- High reliability component:hook, winch, drum, wheel, motor etc
- Light work duty
- Needn’t any column, runway beam, just travel on the ground’s rail
- Suit for both of outdoor and indoor

A Standard Single Girder Gantry Crane Will Be Produced in 30 Days.
Tips: Lead time of cranes with different voltage may be 10-15 days longer, as electrical components need to be customized by our supplier.
Products Details
Support Beam
When export gantry crane, to largely save sea freight, our engineer will try to reduce the goods volume. The support beams is dismountable.
Ground Beam
Ground Beam connect with support legs, travelling on the floor rail. Ground beam use reliable motors, ensure stable travel.
Support legs
Support legs support the main beam and lift mechanism. It can be box type and trussed type due to different use situation
Maintenance Cage
Maintenance cage is a small mechanism, workers can stand on this cage and offer repair or maintenance for crane
Main Beam
Q235/Q345 carbon structural steel. Strong box type with standard deflection. If deliver by container, then need to divide the main beam.
Wheel
Light capacity equipped with general LD wheel, heavy capacity equipped with high quality forged wheel or wheel group
Different Types of Single Girder Gantry Crane
A (MH) Type Single Girder Gantry Crane
- Suitable for indoor and outdoor, Strong box type
- Crane can be designed with two side cantilever, one side cantilever or no cantilever
- Crane equipped with steel wire rope hoist, hoist traversing under the main girder
L Type Single Girder Gantry Crane
Crane leg is ‘L’ type, is it more convenience for large size goods from middle position move to cantilever without any dimensional limit of support leg.
Crane can equipped withtwo type lifting mechanism, one is steel wire rope hoist, hoist traversing under the main girder, the other one is trolley, trolley traversing on the main girder.
Truss Type Single Girder Gantry Crane
- Crane main girder and support leg both with truss type, it is more suitable for open area,can bear strong wind pressure.
- Crane can be design with full truss type or main girder with truss type, support with box girder or on the contrary.
- Crane equipped with steel wire rope hoist, hoist traversing under the main girder
