AI Technical Summary

Technical Problem

The side rollers of existing forklift masts lack a buffer mechanism due to rigid connection, making them prone to wear and jamming due to radial impact, which affects operational stability and safety.

Method used

It adopts a two-way spring buffer structure, which provides radial buffer through the combination design of support column, mounting plate and spring. The spring preload can be adjusted by adjusting the adjustment pad to adapt to different load conditions.

Benefits of technology

It effectively absorbs the radial impact force of the side rollers, avoids wear and jamming, improves smooth operation and safety, and reduces abnormal noise and jamming during operation.
