To solve the problems of the 23 t forklift mast bearing damage experiences - 2019 04 - Author: 18 Zhou Jinxi ( CSP quanzhou Pacific pier) One, the background of 23 t forklift is bought in October 2004, from the first time involved in door frame bearing fracture, manufacturers also could not judge the problem, just replace the bearing. Light in early 2007 to November transformation is 33 broken door frame bearing, each bearing price is 750 yuan, and every stop to change, need three mechanic, spend three hours to repair, increase costs and time-consuming work, affect the production efficiency. Later of the homework, frequent door frame bearing rupture occurred phenomenon, with the development of the production operation, the door frame bearing breakdown phenomenon more and more serious, have not been able to fundamentally solve the problem. Second, the technical way of thinking to find a solution to the problem, have been observed during the normal operations. By comparison with similar forklift working condition of the same work, found that the fork fork teeth in the back seat and the door frame there is a distance of 13 cm gap between ( Figure 1) , forklift operation cannot get fork tooth stress that may due to the stress transfer and direct effect on the door frame bearing, bearing instability. So the idea on the back of the fork teeth on both sides and the position of the gap between door frame and welding out of an iron bridge, make the fork teeth in the back seat and reduce the gap between the door frame around 5 mm ( Figure 2) , so that when the fork teeth at the fork force and affected by the impact, will add some force through welding of iron to the door frame, and the door frame is fixed on the wheel and the body, can stand the force, not cause damage, avoids the impact effect on the bearing directly, indirectly protect door frame bearing, so as to avoid the bearing load and damage. The idea to get technical support and renovation by technology department overhaul shop. Figure a figure 23, technical results according to statistics, since November 2007 reform so far, no found 23 t forklift bearing fracture, also do not have found some disadvantages brought by the revamp, reduce production cost and improve the production efficiency. Four, technological upgrading enterprise equipment technical experience does not necessarily need all complex calculations and a large number of reform to succeed, sometimes through observe, comparisons and serious thinking, appropriate improvement can be successful, 23 t forklift truck door frame modified, for example, only 1 cm thick, two pieces of specifications at about 50 mm * 50 mm plate was improved, it solved the problem of the door frame bearing damage. As long as the intention to observe everything, can produce things method; Only take the correct and reasonable operation way, to guarantee the safety of the operation process. （ Source: cosco shipping port)
