55T Duty A5 European Double Girder Overhead Crane Smooth Running Compact Structure
55T Duty A5 Compact Structure European Double Girder Overhead Crane Smooth Running
Description of Euro Double girder overhead crane
1. This series tables of product only list the general crane with basic specifications, including the standard span at working level A5 (FEM 2m) and indoor crane without auxiliary hook. Customers can make relevant requirements according to their demands.
2. This series can add to auxiliary hoisting mechanism, and also the speed doubler if run with light load. Ordinarily, the setting of the main and auxiliary should be 4:1, which also be set in accordance with requirements of customers. It will increase the total weight and wheel pressure if adding to auxiliary hook.
3. Dimensions, weight and wheel pressure in table will be reference for ordering of customers. If requirements of customers get changed, such as some changes occurred to working level, speed and lifting height, the relevant parameters, dimensions, weight and wheel pressure will also get changed. The actual parameters, quality and wheel pressure should subject to the requirements in contract.
4. Lifting speed, speed of crane and trolley traveling listed in table are standard values, which can be correspondingly regulated according to demands of users.
5. Technical parameters and dimensions would be changed as with improvement or upgrade of technology.

Features of Euro Double girder overhead crane
In general
European optimization design, light dead weight, small wheel load, and short size.
Good driving capacity, double lifting speed, frequency control of trolley and crane
Smooth and stable traveling
A variety of patterns meet customers'needs
Mechanical parts
Single main girder, welding box structure, camber meeting national standard
Steel plate material Q235 or Q345B ( similar with 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.
The trolley and crane adopt three-in-one 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
Trolley
Compact constructure, small size, light weight.
Square steel for traveling rail.
Consists of three-in-one reducer, trolley frame and electric hoist.
Three-in-one structure for trolley traveling
Electrical parts
Safe slide wire provides power whose conductivity is high and voltage drop is small, and current collector slide speed is swift.
Lifting mechanism, trolley and crane can be controlled independently, and work synchronously or individually.
Reasonable layout, simple maintenance and insulation class IP55 for electric control box
Flat cable, galvanized track and cable pulley for trolley traveling power supply, smooth traveling
Electric contactless module speed regulation controlling
Smooth traveling, lifting, and pushing-on
