MACHINES
Total heavy equipment owned outright — no third-party lease required for core scope.
FLEET & EQUIPMENT / DOCUMENT REF. KCG-FL-001
142 Machines. One Privately Held Fleet. Mobilized Across Hokkaido.
The fleet capacity that lets Kenchan self-perform 92% of work scope — from 60-ton crawler cranes to three tunnel boring rigs and a 24/7 batch plant — documented down to the machine count.

01 · FLEET CAPACITY
Fleet capacity, stated as a figure, not a claim.
Before a procurement officer asks about mobilization windows, they ask what we own. The numbers below are pulled from the active KENLOG register as of this document revision.
60T
HEAVIEST CRANE
Top crawler crane capacity in the fleet, deployable without sub-rental.
85T
DUMP TRUCK PAYLOAD
Largest rigid-frame dump truck class in the Hokkaido private fleet.
800m³/d
BATCH PLANT OUTPUT
Sustained daily ready-mix output from the Otaru batch plant during peak pours.

02 · INVENTORY BY WORK CLASS
Inventory organized by the work scope we self-perform.
The fleet is grouped by trade, not by OEM. Each panel lists owned unit counts and the headline capacity that defines the class, so a quantity surveyor can verify mobilization against their own take-off.

03 · FLAGSHIP ASSETS
The machines that move the schedule.
Four assets in the fleet that are unusually difficult for a competing civil subcontractor in Hokkaido to bring to site without sub-rental — documented here so a procurement officer can read the constraint before the RFQ phone call.

04 · KENLOG TELEMATICS
Fleet readiness is measured, not assumed.
KENLOG is Kenchan's proprietary telematics platform, deployed across 100% of heavy equipment since 2020. Every machine in this document is tracked for location, hours, fuel burn, idle time, and mechanical status — a procurement officer is entitled to ask, and we are obliged to answer.
