Underslung Cranes with European Style
European single girder underslung cranes is a light duty europeane cranes which can be installed on the roof of the workplace without bracket, saving space and lowering cost. The trolley is small and loads can be lifted to the place as near as possible to the wall of the workplace. The traveling range of trolley can exceed crane span trough side jib. The lifting capacity of European single girder underslung cranes is 1 to 20 ton and the working class is A5. The main parameters of European single girder underslung crane is shown for your reference in the following table. Customized single girder underslung cranes is available.

Features of Underslung Cranes
Generally, electric hoist of the underslung cranes has the following features:
1. On mechanical parts:
- Single main girder, welding box structure and camber of the underslung cranes meeting national standards.
- The materials of underslung cranes is steel plate Q235 or Q345B (equals to foreign steel plate Fe3 or Fe52).
- Underslung crane main welds joint adopts union melt welding, nondestructive inspection.
- After welding, main girder of the underslung cranes is through shot blasting treatment, gets Sa2.5 class, and eliminate welding stress.
- Main girder and end girder adopts bolted connection to ensure strength and accuracy of the whole set.
- Trolley and crane adopt three-trinity driving mechanism, frequency stepless speed regulating, hard-tooth surface, disc brake.
- Crane driving IP55, F class insulation, contact continuity reaches 40% ED.
- Epoxy zin-rich paint, a long service life, beautiful outlook and lustre.
- Crane buffer block, anti-derail end plate
2. On electrical parts
- Safe slide wire: high conductivity, small voltage drop and swift current collector slide speed;
- Lifting mechanism: independent control system for trolley and crane, synchronous and individual operation is possible;
- Electric control box: reasonable layout, simple maintenance and insulation class IP55;
- Cables: flat cable, galvanized track and cable pulley for trolley traveling power supply;
- Electric contactless module speed regulation controlling.
3. Protection devices
The underslung cranes has the protection devices, such as, overload warning, secondary class anti-clamp, sound and light alarm devices, circuit self-check protector, and flow phase lack protection, etc.
- Underslung cranes has several operation methods for your selection: ground flashlight door, remoter, flashlight door+remoter, etc.
- Ground operation is simple and professional operator is not required and more freedom is given to the crane operator.
- Double stop button or rocker type joystick.
