After-Sales Service for Grab Buckets

After-Sales Service for Grab Buckets

Based on our past troubleshooting achievements, we are intent on providing flexible and quick troubleshooting services by personnel stationed in branch offices at six locations around Japan.
Individual service engineers are assigned to their respective customers to offer follow-up services and, in the event of emergencies, are available around the clock, even on holidays.
We cater to the customer by offering flexible proposals and troubleshooting services: the service engineer responds to trouble with a stop-gap measure when a sufficient period for repair work cannot be secured, but otherwise takes permanent measures.

Patrol Service

As for grab buckets for which the customer wants our maintenance service, we conduct a preliminary checkout free of charge.
We can present the best possible service plan because we prepare a price quotation only after confirming the conditions of customers' machinery in trouble.

Provision of On-Site Services

Not only do we conduct maintenance and troubleshooting in our service workshop, but we can also provide on-site services.
Our capabilities also include overhaul maintenance of hydraulic cylinders as well as servicing worn parts of bucket claws by welding using repair materials specifically made according to the state of wear.

Maintenance of Our Workshop

We perform grab bucket maintenance by bringing in faulty grab buckets to our workshop.
The securely serviced grab bucket then undergoes shot-blasting for surface preparation, and finally its welded parts are investigated to a non-destructive test.
Our customers are highly delighted to see these recoated and completely refreshed grab buckets and always say, "They are as good as new!"
