China Rubber Tyre portable Gantry Crane with cheap price

Double beam structure is applied for the girder, inside which there set the track girder. On the track girder there laid the trolley rail with no seam. Mounting preciseness of the trolley rail conforms to the FEA regulations. Braking devices of the high-speed brake are set on the two ends, which not only ensures stable braking in normal condition but also provides strong braking torque in sudden gust. A safety support is set to prevent the trolley frame from falling once the wheels or axles break. Joints of the trolley rail are Z-shaped for small crush to the rail. The M-room is elegant with appropriate layout in it and splendid decoration on the wall. Advanced coating technique is applied on the outer surface of the M-room. STS is driven by a full digital frequency control system whose recycled energy can be reclaimed to the grid. The transducer applies speed closed loop vector control. Applied with integrate coating technology, STS conforms to the SIS to prevent erosion from salt spray and ocean climate. The telescopic chain of spreader is made of imported metal material with vibration protection and stretching capacity. Imported proximity sensor limit switches are applied on the twistlocks and the lifting pins for sensitive and reliable induction of the limit. STS is configured with the most advanced gantry mechanism in the world up to now. It consists of upper, middle, and low equalizers and is connected with pin shafts. Bogies are mounted for the travelling of gantry. All the structures ensure the equalized force on each wheels and the stable travelling. Now the gantry of Sany STS has been modularized into 8-wheel, 10-wheel, and 12-wheel types for different allowed wheel loads on different ports.

CAE design
Modularity of parts
Top manufacturing technique
Advanced test and detection system
Experienced manufacturing and technology storage
A CAE design system based on multi-platforms is self-developed , in which
parameterized driving, optimized analysis, emulative analysis, simulative test, and
simulative assembly can be carried out.
Improving designing efficiency and shorten designing period for the rapidest deliv-
ery;
Improving designing quality and decreasing designing error for the best quality;
Accumulating designing experience for constant improvement and better products.
Based on the universality of STS parts, we have integrated over 400 hundred mod-
ules including hoisting mechanism, raising/lowering mechanism, tractive mechanism
for trolley, trolley assembly, gantry mechanism, steel structure, functional parts, gen-
eral parts, accessories for M-room, etc.
Sany Ship-to-shore Container Crane applies high-strength full-welding steel structure
conforming to AWS. Every key welding seam has been through 100% nondestructive
inspection to withstand strict test.
Pre-assembly validation and integrate assembly promote preciseness and reliability,
as well as shorten the assembly cycle.
Our professional test teams, with high responsible spirit on science, strictly test the
performance and quality of every product. Numerous tests including fatigue, vibra-
tion, control, and power consumption are included, with parameters of stress strain,
pressure, displacement, speed, acceleration, torque, and power, etc. being set. Only
after the product has passed all these tests can it be mass produced and launched.
Sany has delivered numerous ship-to-shore container cranes, all of which are greatly
acclaimed by customers in and abroad. For your customized need, Sany has devel-
oped STS of various loading capacity, 65t-65m, 50.8t-55m, 40t-40m for instance.
Based on his comprehensive technology storage, Sany would always provide excel-
lent STS rapidly on your need.
