Introduction to Metso Lokotrack Systems / 美卓Lokotrack系统简介
Metso Lokotrack mobile crushing and screening plants have been a leading solution in the aggregates production and recycling industries since their introduction in 1985. These track-mounted machines combine complete mobility with high crushing capacity, enabling operations to process materials efficiently at production sites or move between locations with minimal setup time. The Lokotrack series includes jaw crushers (LT Series), cone crushers, and horizontal/vertical shaft impact (HSI/VSI) crushers designed for primary, secondary, and tertiary crushing applications.
美卓Lokotrack移动破碎和筛分设备自1985年推出以来，一直是骨料生产和回收行业的领先解决方案。这些履带式设备将完全的移动性与高破碎产能相结合，能够在生产现场高效处理物料，或以最短的安装时间在不同地点之间转移。
Cable Requirements for Mobile Crushing Equipment / 移动破碎设备电缆要求
Power cables serving mobile crushing plants face extraordinary operational demands. The continuous crushing action generates significant mechanical vibration transmitted through the entire machine structure. Cables must maintain electrical integrity while enduring repeated flexing cycles, exposure to rock dust, temperature extremes, oil and hydraulic fluid contact, and UV radiation in outdoor installations.
为移动破碎设备供电的电缆面临着极端的运行需求。持续的破碎作业会产生显著的机械振动，并传递到整个机器结构中。电缆必须在承受重复弯曲、岩石粉尘、极端温度、油液接触和户外紫外线辐射的同时保持电气完整性。

Installation Guidelines / 安装指南
Proper cable installation is essential for maximizing service life in mobile crushing applications. Cables should be routed to avoid pinch points and sharp edges. Use cable carriers or festoon systems where cables must move with machine components. All terminations should utilize IP67 or higher rated connectors with strain relief to prevent conductor fatigue at connection points. Regular inspection intervals should be established based on operating hours and environmental severity.
正确的电缆安装对于延长移动破碎设备的使用寿命至关重要。电缆应避开夹紧点和锐边。在电缆需随机器部件移动的地方使用电缆拖链或悬挂系统。所有端接应使用IP67或更高等级的连接器，并配备应力释放装置以防止连接点处的导体疲劳。
