Crawler crane seals, also known as seal kits or oil seals, are components used to prevent leakage of fluids or gases in a crawler crane's hydraulic system. These seals are typically made of durable materials such as rubber or plastic, and they are designed to fit tightly around the moving parts of the crane's hydraulic system to prevent fluids from leaking out.
Seal kits typically include a range of seals, such as piston seals, rod seals, and wiper seals, that are necessary for maintaining the integrity of the crane's hydraulic system. These seals are designed to withstand high pressure and high temperatures, and they are often exposed to harsh environmental conditions, such as dust, dirt, and moisture.
