1. Failure of core functions
The backstop is a one-way locking device, and its internal structure (such as wedges and rollers) has clear directionality. Once installed upside down, under working conditions where the equipment needs to prevent reversal (such as shutdown or power outage), the backstop will not only fail to lock, but will be in a "free" state, causing the equipment to reverse under the action of load gravity or inertia.
2. Risk of equipment damage
The backstop itself is scrapped: After being installed upside down, key components such as pawls, ratchets, springs or rollers inside the backstop will withstand abnormal reverse impact forces, causing local wear to sharply increase, or even breakage and tooth damage, causing the backstop to be directly scrapped.
Damage to related components: Abnormal vibrations and impact loads caused by backstop failure will be transmitted to ZSY reducers, motors and other equipment through the transmission shaft, accelerating the wear of precision components such as bearings and gears, and shortening the service life of the entire machine.
Abnormal shutdown: Installing the backstop backwards may cause additional resistance or jamming of the equipment during operation, triggering the generator overload protection, causing unplanned shutdowns, affecting production efficiency and possibly damaging the electrical system.
3. Serious safety accidents
This is the most dangerous consequence of installing a backstop. On key equipment such as elevators and inclined belt conveyors, backstop failure will cause:
Material backflow and falling: The load is reversed out of control, causing material to accumulate, scatter, or even fall from a height.
Mechanical injury: High-speed reversing parts may fly out or cause serious mechanical injuries to surrounding operators during the reversing process.
Major production accidents: In mines, power plants and other scenarios, equipment reversal may cause serious accidents such as belt tearing, drum damage, and buried tails, resulting in heavy casualties and property losses.
