Generally, European electric hoist crane has the following features:
1. On mechanical parts:
Single main girder, welding box structure and camber meeting national standards.
Steel plate material Q235 or Q345B (equals to foreign steel plate Fe3 or Fe52).
Main welds joint adopts union melt welding, nondestructive inspection.
After welding, main girder 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 equipment: 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.

4. Protection devices
European electric hoist overhead crane 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.
Electric hoist overhead crane 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.
