常见问题

壳体螺栓松动

顶部与底部组件上的壳体螺栓长期承受剧烈振动与疲劳负荷,易导致夹紧力下降乃至连接失效。
解决方案: Superbolt® 紧固方案可为大型破碎机壳体提供安全、均匀的夹紧力,且无需超高扭矩即可实现可靠锁紧。

Spider bolt loosening

Spider joint bolts are critical to crusher integrity but face extreme vibration, impact loads, and thermal cycling. Traditional bolting can lead to preload loss, safety risks, and difficult access due to confined spaces around the spider housing.

Solution: Superbolt tensioners deliver accurate, safe preload using only hand tools—eliminating the need for high-torque equipment or complex reaction fixtures and simplifying maintenance in tight spaces.

Difficult access for accurate preload

Mantle and spider joint bolts require high and uniform preload but are difficult to tighten accurately due to confined access and large sizes.

Solution: Boltight® hydraulic tensioners deliver uniform preload even in challenging or tight assembly locations, reducing maintenance and improving performance.

Foundation instability

Foundation bolts are stressed by continuous crushing force, and loosening can lead to misalignment, cracking, or unplanned downtime.

Solution: Superbolt tensioners ensure accurate preload on crusher foundation bolts, preventing loosening from vibration and impact while eliminating the need for high-torque equipment during installation and maintenance.
