Power That Goes All Day.
The benchmark for high-cycle foundation work across NZ and Australia.
Kobelco Heavy Duty Crawler Cranes are built around one requirement: keep cycling, under load, all day. Wet-type disc brakes deliver controlled free fall, large-capacity drums handle the volume, and a dual hydraulic flow circuit keeps both winches in precise sync. KCROSS remote monitoring watches the machine while you watch the job.
Every model in this range arrives configured for foundation applications, not adapted after the fact.
The wet-type disc brake system handles free fall reliably under load, the dual hydraulic circuit synchronises the winches, and high-output engines deliver the pull and line speed that pile driving and earth drilling demand.
-
Dual Hydraulic Flow Circuit
On a foundation site, two winches running out of sync creates errors that are difficult and costly to recover from.
Independent hydraulic circuits eliminate that problem, delivering consistent synchronisation across the full working shift regardless of load variation. -
Wet-Type Disc Brake with Free Fall
The wet-type disc brake runs in oil, managing heat and wear across high-cycle foundation shifts far more effectively than dry alternatives.
The operator gets consistent, predictable stopping performance on every drop and every hold, shift after shift. -
Large Capacity Winch Drums
Wide, large-capacity drums are sized for the depths and heights that civil foundation work demands. The job runs without interruption because the machine isn't stopping to respool mid-shift.
-
High Output Engine
Foundation work loads the engine continuously. Sized specifically for sustained heavy-duty output, the engine maintains consistent hydraulic flow and line pull across the full shift, so performance doesn't fall away as the day wears on.
-
KCROSS Remote Monitoring System
When KCROSS identifies a fault, the diagnostic data is already with the service team before anyone leaves the depot. For machines on remote civil sites or under tight programme schedules, that speed of diagnosis directly reduces downtime cost.
-
Multi-Application Attachment Compatibility
The range is configured to run pile hammer, vibrating hammer, earth drill, clamshell, and casing oscillator attachments.
A civil contractor can carry one machine through multiple foundation phases of a project instead of bringing in separate equipment for each task.
Power, Reach and Control
At 80 t, 100 t, and 120 t maximum lifting capacity, this range is sized for foundation applications that push standard cranes past their limits.
Boom lengths up to 62.6 m reach the depths that piling and earth drilling programmes require.
All three models are engineered for high-cycle continuous operation, not occasional heavy lifts.

Frequently Asked Questions
-
What foundation applications do these machines handle?
The BMS and 7120 series are configured for pile hammer, vibrating hammer, earth drill, clamshell, and casing oscillator work.
They're purpose-engineered for high-cycle civil foundation operations, not adapted from a general-purpose crawler. If your programme involves any combination of these tasks, these machines are set up to run them.
-
What's the difference between the BMS800, BMS1000, and 7120SFS?
The BMS800 tops out at 80 t lifting capacity with a maximum boom of 54.9 m. The BMS1000 steps up to 100 t and 62.6 m. The 7120SFS delivers 120 t at a 5.0 m radius at maximum load, suited to large civil infrastructure projects with demanding lift requirements.
The TRT crane team will match you to the right model based on your programme.
-
Can I get attachment and rigging support through TRT?
TRT supports the full Kobelco heavy duty range and can advise on attachment compatibility for your specific application.
Talk to the crane team about your programme and they'll confirm what's available and what works with your model.
-
What does KCROSS do and how does it affect my operation?
KCROSS is Kobelco's crane remote observation satellite system, included as standard across the range.
It gives TRT's service team access to machine data remotely, which means they can diagnose a fault, order parts, and plan a response before a technician leaves the depot. Less guesswork means faster return to service.
-
What does TRT's service coverage look like for these machines?
TRT services Kobelco heavy duty crawlers across NZ and Australia.
The crane service team is available 24/7 for urgent callouts, and TRT carries parts to support the full range. If you're working a remote civil site, that support reach matters.
-
How do these machines hold up on long, high-cycle foundation programmes?
They're engineered for exactly that use case. The wet-type disc brake system, large-capacity drums, and dual hydraulic flow circuit are all specified for sustained high-cycle operation, not occasional heavy lifts. KCROSS monitoring also catches developing issues before they become unplanned stoppages.
