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:
