Double Girder Top Running Bridge Crane
Double Girder Top Running Bridge Crane
Double Girder Top Running Bridge Crane compared with the general double beam bridge crane, its weight is reduce by about 15-30%, the max wheel presuure is redured by about 10-35%, which can reduce the requirement of factory building structure and reduce production cost.
The main beam employs bias-rail box-type structure and connects with end beam by high-strngth bolt ensure easy transportation.Trolley uses open compact winching structure, which with meduim and small ton can use new hoist trolley. Traveling mechanisms of crane and trolley adopt European three-in-one drive form, the harden grae face reducer has good performances in compact structure, low noise, no oil leakage and long service life.
As using new compact trolley and high-strength materials, European eot crane has small overall dimension and light weight. Compared with traditional crane, which can decrease the height of factory building and reduce the cost. Full variable-frequency control runs steadily without any compaction. Run with heavy load at low speed and light load at high speed, it can save energy and reduce comsumption.
LIGHTWEIGHT DESIGN ：Reduced Dead Weight Lower Building Load
LOW HEADROOM：Maximum Lifting Height · Optimized Workshop Space
HIGH-EFFICIENCY DRIVE：Smooth Operation · Lower Energy Consumption
PRECISION CONTROL：VFD Control · Smooth Start & Stop · Accurate Positioning
LOW MAINTENANCE：Modular Components · Easy Maintenance · Reduced Downtime
SMART & SAFE：Anti-Sway · Overload Protection · Remote Monitoring
Double Girder Top Running EOT Crane Advantages:
（1）Light self-weight
Design software developed by the company combine with three-dimensional modering and finite-element analysis, apply the reasonable structure to lifting mechanism, steel construction and accessories, together with wide use of high-strength material, it increases load capacity, decreases self-weight and has lower weight and wheel pressure than that of traditional crane.
（2）Small space use
Limit distance from hook to boat sides is short but has large working arrange. with lower height above the rail, it makes full use of space of factory building,
（3）Low cost of running and maintaining
As with low wheel pressure and small dimension, it reduces investment of previous construction including factory building, and also reduces illumination and heating expense. The reilable performance and durability also minimizes the additional charges for the use of product at the later stage. Selected components with high quality and preformance lower the maintenance and repair. The total power consumption is reduced, which achieves cost savings.
（4）High performance
Use variable-frequency technology, run with heavy load at low and light load at high speed. The adjustable speed ranges in 1:10, which ensures crane run steadily and reduces impact on factory building. Combination of swing-proof technology achieves a high accuracy position of lifting items.
