Tips of overhead crane lubrication
What are functions of crane lubrication? It can control the friction, reduce wear and tear, lower the equipment temperature, prevent the parts from rusting, and form a seal. All these functions rely on and influence each other. It not controlling the friction, reducing wear and tear is impossible, this can produce much friction heat and lead high temperature of equipment, thus damaging the lubrication of friction surface and lubrication material. To extend crane’s long service, regular and timely lubrication is very essential.
