The micro trencher cuts a shallow, narrow slot for fiber routes in streets and sidewalks with minimal damage to the surface. Reinstatement is faster and cheaper than with a conventional trencher.

Key features

Shallow cut for microduct and micro cable.
Compact chassis for sidewalks and narrow streets.
Low ground disturbance and reduced spoil.
Quick blade change for different surfaces.

Applications

◈

Urban projectsprecise trenching on busy routes with minimal traffic disruption

◈

Fibre contractorsnarrow trenches for fibre ducts in built-up areas

A new trenching method

New-generation microtrenching blades

With milling bits, every asphalt and subgrade component is separated and removed, and the trench is 10 to 12 cm wide. With cutting blades, the material is sheared and the trench is 1.5 to 3.4 cm wide. The result: a smooth, even trench bed, one-eighth of the debris, an average speed of 4 instead of 2 metres per minute, and up to 90% less downward pressure from vehicle wheels on the buried route.

Narrow trench1.5 to 3.4 cm instead of 10 to 12 cm
Less debrisA quarter of the excavation waste and one-eighth of the total debris
Smooth bedShearing leaves a clean bed without sharp edges, so little bedding sand is needed
Reuse screened soilScreened soil and crushed rock go straight back into the trench
FasterAn average of 4 m/min against 2 m/min
Rocky groundConcrete and rock beds can be cut, more slowly and with more wear
Traffic keeps moving75% fewer crews and one-eighth of the debris vehicles
Less pressure on the ductUp to 90% less downward pressure on the subgrade

In the field

From the machine to the restoration

Real jobs done with the new-generation blade.

Trenching machine Continuous cut

Cut width: 1.5–3.4 cm
Speed: up to 4 m/min
Ground: Asphalt and rocky bed

Trench edge Even bed

Bed: Smooth and clean
Bedding sand: Minimal
Restoration: Faster

Street works Traffic keeps moving

Crews: 75% fewer
Debris vehicles: 1/8
Disruption: Minimal

Working crew Speed and safety

Labour: Less
Safety: Lower risk for pedestrians and cars

Rocky bed Cutting through rock

Capability: Concrete and rock beds
Cost: More tool wear

The two methods compared

The new cutting blade against conventional milling.

Parameter	Cutting blade (new)	Milling (previous)
Trench width	1.5 to 3.4 cm	10 to 12 cm
Average speed	4 m/min	2 m/min
Debris volume	One-eighth of the previous method	Baseline
Debris removed from the trench	All of it	Half stays in the trench
Trench bed	Smooth and even	Uneven, needs fine sand
Bedding sand	Minimal	High
Screened soil	Fully reusable for backfill	Limited
Width growth in loose soil	Up to 5 cm	Three to four times wider
Rock and concrete beds	Can be cut, more slowly	Practically not drillable
Crews	75% fewer	Baseline
Debris vehicles	One-eighth	Baseline
Pressure on the bed	Up to 90% less	Maximum pressure on the duct
Restoration	Fast, often without concrete	Slow and expensive

All figures come from the official “New Generation Microtrenching Blades” presentation (September 2024); it compares the cutting method with milling and is not a machine data sheet.
