Quarry Maintenance Team Repairs Excavator Tracks On-Site with Our 70T Bushing Press
When track bushings fail in a quarry, the resulting downtime adds up fast. Normally, pulling the equipment out and hauling it back to a shop takes days and costs a lot of money. To avoid a long shutdown, a quarry maintenance team recently used our 70-ton on site bushing press to handle the repair directly at the working face. By bringing a portable crawler bushing press to the machine, they finished the emergency fix without moving the excavator. This case clearly demonstrates the practical value of a mobile construction bushing press in mining operations.
Why Field Repairs Matter in Quarry Operations
Quarry pits are brutal on undercarriage components. Constant exposure to rock dust, moisture, and heavy shock loads means pins and bushings seize fast. The old routine was simple but painful: hook up a trailer, drag the machine to a specialized shop, and pay for crane rentals. It bleeds your production schedule dry.
The crew needed to press out the worn bushing and press in a new one right there in the dirt. To do that, they needed the right tool. This equipment is available in two distinct models: an electric-driven hydraulic track bushing press for sites with generator access, and a manual hydraulic bushing press for remote pits without a power grid. Users can choose the specific configuration that best fits their actual site conditions. Having that flexibility means they never have to wait for logistics to line up.
Using the 70T Press for On-Site Bushing Replacement
This 70-ton hydraulic bushing press unit is utilized for undercarriage maintenance. Its structural configuration supports stable operation in field environments, including muddy and uneven terrain.
The actual repair process is straightforward. You lock the tooling into place, apply hydraulic pressure to push out the seized bushing, and thoroughly clean the link bore of any debris. Then, you press in the new one.
The critical part here is alignment. If the pulling rod is off-center, you will score the inside of the link and ruin the part. That's why this unit uses a 50mm hollow center hole. The rod goes straight through the cylinder axis, keeping the force perfectly coaxial with the bore.
With a 100mm cylinder stroke and a 60mm to 120mm pressing range, the bushing seats smoothly in one go. The double-acting hydraulic system also gives the operator complete control over the extraction and insertion phases, which is essential when dealing with rusty, stubborn pins.
Reducing Excavator Downtime and Repair Costs
The results were straightforward. By eliminating the transport fees and crane rentals, the repair paid for itself in terms of saved logistics costs alone. The excavator was back to work in a fraction of the time, and the new press fit restored the machine's structural integrity.
The maintenance lead was direct about the outcome. He said the compact crawler bushing press, which operates as an on site bushing press right at the working face, is exactly what a mining operation needs when tracks go down. It's not just about saving money; it's about keeping the pit running. As an industrial bushing press manufacture, hearing that kind of feedback from field crews is what tells us the design is working. The equipment investment paid off after just one repair.
A Mobile Solution for Heavy Equipment Maintenance
If you are tired of hauling broken machines out of the dirt, bringing a 70-ton hydraulic track bushing press to the job site changes the game. It directly solves the downtime problem that plagues quarry and mining operations.
We build these units to last, and we can adjust the specs to fit your exact fleet. If you need a construction bushing press for your service truck or a specialized manual hydraulic bushing press for remote sites, we can set it up. You can keep your machines working instead of letting a seized pin halt your whole production line.
