ご依頼背景

We received an inquiry from Client A in Fukaya City, Saitama Prefecture, stating, “There is an oil leak near the travel motor of our Hitachi ZX135US-3, and we need an urgent response.” Given their busy project schedule, they specifically requested to minimize downtime.

If left unaddressed, the oil leak would have progressed, inevitably damaging the travel motor and internal components, potentially requiring a full replacement of the assembly.

Through our prompt response and precise repairs, we minimized costs while restoring the machine’s performance to like-new condition.
