How to extend working life of wire rope in Dongqi Crane’s 25 ton overhead crane
As one of crucial parts in any overhead crane, wire rope plays an important role during the use of materials lifting machines. However, due to frequent using, the wire rope is more prone to damage, then how to extend the service life of wire rope efficiently, what measures should you take?
After many years practice, we conclude several valid steps to lengthen the working life of overhead crane’s working life.
- Wire rope of tackle block comes out of groove
Before, wire rope of tackle block below hook comes out of groove frequently; this situation can be solved easily by resetting when nothing serious. However, once the wire rope move into the gap between two pulley blocks, it’s only under the condition that two or more persons work together hitting it fiercely with sledge hammer can restore the wire rope. However, it still is a bad method, because of the huge damage it creates on the wire rope. What is worse, once the wire rope comes out of the groove a time, this situation will happen more frequently, every work team will deal with this kind of trouble three times at least.
After analyses the reason carefully, we found that the round steel is too thin to fix the position of tackle block, as well as the diameter of the round steel is only 25mm, not only without enough intensity, but due to its bending deformation, leading to the big gap between the back plate and pulley blocks, that is why the wire rope will comes out of the groove more times.
Finally, aimed at the defect, we improve the diameter of back plate from 25mm to 40mm, and adjust the space between the back plate and tackle block from 10 ram to 5 ram, this strong and rigid back plate ensure the certain freedom of wire rope, at the same time, it also suit for the technology requirements.
2. The transform of suspension girder
Due to all several shapes of materials stocked in warehouse, the hook always works in the state of slope; this is particular true when more cargoes enter into factory. On that moment, closed wire rope will rub the three broadside of steel plate on suspension girder, leaving some serious abrasion in the middle of wire rope. After this takes place a few times, the wire rope will broke stand and even be scrapped in a short time. And also make certain friction on hanging beam.
The moment we find the reason, our professional experts’ team will research some new ways to avoid this phenomenal show up again. During more time practice and test, we find a better way. First, we raise the intensity of hanging beam, and add the thickness of plate steel from 10 ram to 14 ram, as well as the width from 250 ram original to 305 ram, length from 850 ram to 950 ram. Second, equipped two pulleys with the scale of 60mm*250mm on these three side, which between the hanging beam and the wire rope.
