European standard (also known as Euro-style or HD type) single girder cranes and traditional LD/LDA type single girder cranes are both used for material handling in workshops, but they differ significantly in design philosophy, structural performance, and economic efficiency.
|
Comparison Dimension |
European Standard Single Girder Bridge Crane (HD Type) |
LD/LDA Type Single Girder Bridge Crane |
|
Design Philosophy & Standards |
European lightweight, modular design (DIN/FEM/ISO) |
Traditional Chinese design (JB/T 1306, etc.) |
|
Structure & Self-weight |
Compact structure, light self-weight (~30%-40% lighter), mainly box girder |
Relatively bulky and heavy structure, main girder mostly I-beam or combined section |
|
Drive Mechanism |
"Three-in-one" drive motor (integrates driving, braking, and speed reduction) |
Separate motor, reducer, and wheel assembly |
|
Hoist Trolley |
European-style electric hoist, trolley runs on rails on both sides of the girder bottom |
CD/MD type electric hoist, hoist runs on the lower flange of the I-beam (below the main girder) |
|
Hook Approach / Headroom |
Very low, provides greater effective lifting height, saves plant space |
High headroom, occupies more plant space |
|
Running Performance |
Often uses frequency control for smooth operation and precise positioning |
Mostly conventional control, relatively higher impact and sway during start/stop |
|
Duty Class |
Typically up to A5/A6, suitable for higher frequency of use |
Typically A3-A4, suitable for medium frequency of use |
|
Manufacturing Process |
High; main girder can be made with full-length plates and no butt welds, automated cutting |
Main girder usually has butt welds at both ends |
|
Initial Cost |
Higher |
Lower |
|
Life Cycle Cost |
Lower (energy-saving, less maintenance, long service life) |
Relatively higher (relatively higher energy consumption and maintenance costs) |
