常见问题
悬架与车轴的安装螺栓在承受冲击和持续动态载荷时可能发生松动，这会带来车辆失稳或部件失效的风险。
解决方案： Superbolt® 支柱套件不仅能有效预防冲击引起的松动，从而提升车辆安全性，还简化了预紧力的施加流程。该套件无需过高扭矩，即可为关键悬架连接处提供安全且均匀的预紧力。
Axle pivots, radius rods, and body joints wear down over time, creating slack and misalignment that affects steering and ride quality.
Solution: Expander® System pivot pins remove slack in pivot connections, eliminates pivot wear in axle and body connections, extends service life and removes the need for oversized repairs.
The Superbolt Tool allows for fast, safe, and consistent tightening of Superbolt tensioners on rope shovel side frame connections, improving serviceability in confined or high-load areas.
Traditional bolted joints are not ideal for these applications. Torque-based tightening leads to inaccurate loading levels, causing torsion, galling, and harder removal. Combined with vibration and thermal cycling, this results in preload loss and potential failure of critical connections.
Solution:
Superbolt tensioners eliminate these issues by providing accurate, torsion-free tightening. They maintain precise preload across steering linkages and other dynamic joints, ensuring long-term reliability and easier maintenance.
Smaller accessories like lights, mirrors, and handrails are prone to loosening due to continuous chassis movement and high-frequency vibration.
Solution: Nord-Lock® wedge-locking washers provide maintenance-free security for accessories, engine mounts, and frame bolts.
