Hydraulic trencher MH45

with chaintractor-mountedself-propelled

Overview
The MH45 is a hydraulic trencher designed to be fitted to 8+ tonne excavators. Take on trenching work with a medium-size excavator – 3 to 5 times faster than with a digging bucket.

The MH45 at a glance

• Between 50 and 75 metres/hour* (speed factors: ground conditions, depth and width of the trench)
• Ideal for fibre optic cables, water pipes and drainage/irrigation systems
• Produces a clean-cut & narrow trench
• Productive backfilling with spoils left on one side of the trench (auger places finely cut spoils)
• A fraction of the cost of a self-propelled trencher

Main features & components

• Maximum depth: selectable options 0.8 m, 1.0 m or 1.2 m
• Trench width:
  • Standard boom & chain: 125 to 200 mm
  • Optional narrow boom & chain: 64 to 84 mm
• Standard chain with individual links fitted with soil blades & carbide teeth OR welded narrow chain
• Soil evacuation auger to place finely cut spoils to the side of the trench for fast backfilling
• Direct drive motor to enable optimum power and torque to the digging chain
• Attachment intended for excavator mounting
• Weight (approximate): 400 kg

Excavator requirements

• Minimum excavator mass: 8+ tonne
• Hydraulic supply: direct & continuous hydraulic oil supply
  • Flow: 100–150 L/min
  • Pressure: 160–180 bar

Why choose the MH45?

• Productivity – dig 3 to 5 times faster than using a digging bucket
• Clean trench – pipes, ducts and cables can be easily laid at the bottom of a clean trench
• Rapid backfilling – auger places spoils to the side for quick backfill with a simple blade
• Minimal maintenance – visual inspection, monthly greasing, chain tension and teeth wear checks; long service life if maintained
• Ease of use – operable by any experienced excavator operator
• Cost-effectiveness – lower capital cost compared with self-propelled trenchers
• Fast spare parts delivery and availability to support uptime

Frequently asked questions (summary)

• Can the MH45 go on any excavator? The MH45 requires a minimum of an 8-tonne excavator with direct and continuous hydraulic oil supply of 100–150 L/min at 160–180 bar.
• Is the MH45 easy to maintain? Yes — any skilled excavator driver can perform routine maintenance and inspections.
• How long will the chain last? Chain life varies significantly with soil conditions, trench depth/width, chain tension and usage.
• How will the chain cope with stones? The MH45 is designed for varied ground conditions and can cut through or pull out small stones; for asphalt or larger stones a larger model is recommended.
• Typical trenching speed: typically 50 to 75 metres/hour depending on soil conditions.
