How to Maintain Excavator and Trencher Tires?

Excavator and trencher tires are construction machinery components that utilize a multi-layer reinforced cord carcass and a specialized tread compound. Their tread features a deeper and wider tread block design, combined with strategically spaced grooves, providing both cut resistance and self-cleaning properties. The tire body consists of a high-strength carcass ply and steel belt ply, forming a pressure vessel structure. Thickened sidewalls enhance impact resistance.

In soft, wet terrain, the widened tread blocks of excavator and trencher tires increase the contact patch and prevent sinking. On rugged mountain terrain, the deep tread compound effectively protects against sharp rocks. In areas densely populated with rebar and gravel, the steel cords in the belt layer prevent foreign objects from piercing the tire body.

So how should maintenance be performed?

Before daily operation, check the tire pressure of your excavator and trencher tires to ensure it is within the normal range. Allow for thermal expansion in high-temperature environments, and add a pressure compensation value in cold climates. When installing twin tires side by side, maintain a safe pressure differential to prevent uneven wear. Immediately check the inner liner for airtightness if pressure is abnormal. Immediately remove any debris or metal shavings embedded in the tread grooves after operation. When removing sharp objects, use a special hook along the groove path to avoid pulling vertically and widening the wound. Perform professional repairs on punctures deeper than a specified percentage of the tread thickness.

Also, use a depth gauge to measure the remaining depth of the main tread grooves. Initiate replacement procedures when wear signs appear.

Does a longitudinal crack in the tire sidewall affect its use? 

Excavator and trencher tires can continue to be used under monitoring if cracks do not reach the carcass ply. Exposed carcass must be removed from service immediately.

How should abnormal tire vibration be addressed after wetland operation?

Clear compacted soil from the inside of the rim. Inspect the carcass for any partial out-of-roundness. Check the tread grooves for blockage, resulting in unbalanced mass. If these factors are eliminated, dynamic balancing is required.
