AI Technical Summary
The telescopic booms of existing multi-section aerial work platforms are prone to misalignment after long-term high-load operation, resulting in a significant reduction in sliding performance. The traditional nylon sliding plate is not parallel, which also affects the sliding effect.
A roller mechanism is used instead of a nylon skateboard. The roller mechanism includes a mounting bracket and rollers. The rollers are installed at the bottom of the telescopic arm to ensure that the rollers fit tightly against the telescopic arm and provide assisted sliding.
It improves the sliding effect of the telescopic boom, reduces the component failure rate, and simplifies the installation and maintenance process.
