The adverse effects of improper hook stabilization operation on bridge cranes
During the operation of a bridge crane, if the hook, lifting equipment, and suspended objects cannot be smoothly started, operated, and stopped, significant sway will occur, which is known as improper hook stabilization operation. Firstly, analyze the impact of poor hook stabilization on the equipment:
1. Improper hook stabilization operation of the bridge crane can cause damage to the bridge itself during long-term and intense wandering;
2. It has an impact on the mechanism of the overhead crane, especially when the driver has a bad habit of using reverse braking, which not only causes the suspended object to wander severely, but also the inertia and impact generated during the wandering of the suspended object may cause the anchor bolts of the gearbox of the bridge crane to loosen or break;
When the crane itself has a phenomenon of gnawing on the track, if the braking torque deviation of the brakes on both sides of the crane operating mechanism is large, the additional torque generated by the wandering of the hook and the suspended object and the gnawing torque may be combined, which may cause deformation of the bridge and the factory building. Furthermore, poor hook stability also has an impact on safety: 1. When starting, if the bridge crane cannot start smoothly, the lifted object may sway after lifting, which can easily cause collisions with surrounding people or equipment and lead to unsafe accidents; 2. Improper hook stabilization during operation can lead to ineffective control of the suspended object, which can cause greater shaking of the hook head or suspended object under unstable conditions during start-up, making it difficult to stabilize the hook head or suspended object in a timely and efficient manner, resulting in greater safety accidents; If stability cannot be achieved when parking, it is also easy to cause damage to people or equipment around. The driver's poor skills in stabilizing the hook will inevitably have a serious impact on production: 1. Impact on the effective operation rate of locomotives: In the operation principle of bridge cranes, stabilizing the hook is the cornerstone, and stability is not the basis. It cannot be achieved quickly, nor can it guarantee accuracy. It may even occur that the faster one wants to go, the more severe the shaking of the lifted object, and the faster one wants to go, the less efficient the work;
2. Unstable production cannot be guaranteed: accidents not only cause serious losses to the lives and safety of employees and the property of the factory, but also inevitably have a serious impact on production, even stopping production, resulting in incalculable losses. The above points are all adverse effects caused by improper hook stabilization operation of bridge cranes. It is necessary to promptly prevent such incidents and ensure the safe progress of construction.
