Container crane development trend: rated lifting capacity has increased exponentially. The rated lifting capacity under the spreader has gradually increased from 30.5t to 61t, and now it has reached 65t. The outreach is getting bigger and bigger. With the continuous large-scale container ships, the ship width has increased from the 3rd generation of Panama container ships 13 rows to the current super-Panama ship 14 to 17 rows of boxes, and even 20 rows of boxes of the ship according to the plan will come out in the next century, 22 rows of boxes of the ship is also in the design. And the envisioned 24-row Malacca-type ship (with the ship’s draft depth rather than the ship’s width to define the ship type) will appear in the early next century.
As container ships are getting larger, their width has almost doubled from 26-28m when carrying 600-1,000 boxes to 45m now when carrying 6,000-8,000 boxes. The outreach of the quay bridge is also gradually increased from 32m to 65m now, and will be increased to 70m in the future to adapt to the needs of the so-called Malacca-type ships with 24 rows.

Shipping container crane manufacturer is still widely used, there is a very important part of the container door crane is the wire rope, wire rope if there is a problem will seriously affect the use of container door crane, so we have to pay extra attention. Today we will talk about the maintenance and scrapping of wire rope.
Crane for shipping container price wire rope scrapping standards mainly include the following points: rope end broken wire: rope end or rope end near the broken wire, can cause local; rope strand fracture: rope strand fracture as a whole, may be caused by the rope core damage; elasticity is reduced: refers to the elasticity of the wire rope is significantly reduced, its specific performance, including the rope diameter is reduced, the elongation of the twist distance, the gap is reduced and so on.
Crane to lift shipping container supplier rope maintenance is also a very important aspect. Maintenance work, should pay attention to the following matters: container door crane wire rope should be used in accordance with the specified requirements, the use of the process is strictly prohibited dragging, throwing and other phenomena, so as not to shorten its service life, not to mention the use of overload. Wire rope should not be bent at an acute angle, and should be prevented from shock load. Container door crane once there is rust, dirt and so on. On the wire rope, should be cleaned up in time. Wire rope should be lubricated every once in a while, but should use the appropriate lubricant to achieve good lubrication effect. Container door crane wire rope coiled, should be placed in a clean and dry place, to avoid stacking and twisting. When using the wire rope, if the surface extrusion of oil droplets, at this time can not increase the load. Check and replace if necessary.
