Efficiency in excavation, infrastructure and pipeline work.
Efficiency in excavation, infrastructure and pipelines
Water, gas, power and telecom infrastructure requires trenching across a wide range, from small connection lines to pipelines hundreds of kilometres long. The ground may be rocky, frozen or soft, and work is often carried out close to settlements and existing infrastructure.
With an attachment range suited to every ground type, HKM delivers a narrow, clean trench profile, low-vibration excavation and fast progress. Choosing the right attachment determines both efficiency and environmental safety.

Breaking rock and hard layers
Breaks rock, concrete paving and hard layers along the trench route without blasting; keeps excavation progressing without interruption.
Detailed use scenario
Pole and point drilling
Drills fast, clean circular holes for lighting/sign poles, piles and point holes; disturbs the surrounding ground as little as possible.
Narrow trench profile in rock
Opens a narrow, precise trench profile for gas, water, power and fiber in hard ground with low vibration; works in a controlled way near settlements.
- A narrow, even-bottomed trench is milled for pipes and cables along rocky routes.
- Lines close to existing utilities and buildings are worked with low vibration.
- Smooth trench walls reduce bedding and backfill work.
Surface leveling and slope
Works at high throughput on trench edges, slopes and surface correction with the axial drum; provides a precise, vibration-free finish.
- Trench edges and slopes are corrected in a single pass with the axial drum.
- The trench bottom is finished flat, ready for pipe bedding.
- In narrow corridors, the drum aligned with the stick makes access easier.
Reuse the excavated material
Sizes the rock and fill coming out of the trench on site, making it reusable as backfill/aggregate; reduces hauling.
- Rock and debris from the trench are crushed and reused as backfill for the same line.
- Truck trips to the tip and hauling costs are reduced.
- Site dependence on external aggregate supply drops.
Fast switching along the trench
Raises field productivity along the trench line with switching between auger, breaker and bucket in seconds.
- Along the trench line, the operator switches between bucket, breaker and auger from the cab.
- The attachment rotation is planned around the work sequence; the machine never idles.
- The pin lock is checked at every change to confirm a secure connection.
Loosening on the route
Increases excavation speed by loosening medium-hard and layered ground along the trench route without blasting.
- Layered and weathered rock along the route is loosened by ripping.
- The loosened material is removed with a bucket; breaker use shrinks to limited spots.
- In frozen ground, excavation speed is maintained through winter.
Drill-and-crack line (soon)
Creates a breaking/cracking line for trenching and cuttings by drilling holes in hard rock. This product line is under development.

Frequently Asked Questions
Which attachments are needed in earthmoving and infrastructure?
Hydraulic breakers and rippers for ground breaking, augers and breakers for trench/foundation digging, and quick couplers for fast attachment changes.
Which class suits asphalt and concrete breaking?
Medium/heavy breakers by workload; the right tool type (blunt or moil) markedly increases output.
