Electric Hoist Single Girder Gantry Crane is used together with CD MD Model electric hoists. It is a track travelling small and medium-sized crane.
The Gantry Crane is composed with main girder, electric hoist, legs, ground girder, electrical device and long travelling device.
◆Customized design base on GB/ISO/FEM/DIN/BS standards.
◆High efficient, with the work class: ISOA3-A5, FEM 1m-2m.
◆The frequency-converter can be installed.
◆Remote control, pendant control can be equipped.
◆Inspection standard for load test: Dynamic/ Static load test 1.1 times/1.25 times.
◆Light self- weight & Small space use.
◆When hoist is located at the mid-span, loaded with natural frequency of the main beam is less than 2Hz.
◆Main beam used European FEM standard off-track box beam.
◆High quality carbon steel Q235B or Q345B（16Mn）.
◆Use submerged arc welding in main welding line.
Electric Hoist mechanism
