Schmaler Kabellöffel oder Drainagelöffel (15 cm) mit Symlock-Aufnahme, passend für Schnellwechsler MS01 bis MS03 von LIS Germany.

LIS® Cable Buckets Mini Excavator (also as Clay Buckets)

Specialized cable buckets (150 mm) for mini excavators from 0.5 to 3.5 tonnes. Conical design for optimal emptying – ideal for precise trenching and cohesive soils. Available with adapter based on SY01 or SY03 geometry.

Terms such as MS01, MS03 or Symlock are commonly used in the market and serve solely to identify the geometry.

Conical Design prevents Sticking

This special bucket (often searched for as a drainage shovel or clay bucket) is part of our comprehensive range of Excavator Buckets and solves a common problem in civil engineering: the sticking of cohesive material. The LIS® cable bucket is conically shaped on the inside (widening outwards). The technical advantage: This geometry breaks the vacuum when dumping. Even wet clay, loam, or sticky topsoil slides out cleanly ("self-cleaning effect"). Tedious shaking of the bucket is eliminated.

Applications: Fiber Optics, Drainage & Clay

Due to the narrow cutting width of 150 mm and the smooth cutting edge, the bucket is ideal for:

  • Pipeline construction: Digging precise trenches for fiber optics (FTTH), power, and water.

  • Clay soils: Efficient excavation without clogging (Clay Bucket function).

  • Drainage: Creating narrow seepage trenches in landscaping.

  • Exploratory digging: The toothless edge minimizes the risk of damaging existing lines.

Mount & Compatibility

Since this bucket size is used on micro excavators as well as 3.5-tonne machines, we offer two variants:

  1. SY01 geometry (fits MS01 / SW01 – usually up to approx. 2.0 t)

  2. SY03 geometry (fits MS03 / SW03 – usually from approx. 2.0 t to 3.5 t) Both variants feature a reversible adapter (Symlock function).

Note on terms: Terms like Lehnhoff MS01/MS03 serve here solely to identify the matching quick coupler geometry.

Material & Reinforced Construction

A narrow, deep bucket is exposed to high torsional forces. Therefore, we rely on massive material thicknesses for maximum durability:

  • Cutting edge made of high-strength wear steel HB500 (110x12 mm)

  • Extra strong side plates made of 10 mm S355 steel (prevents bending in the trench)

  • LIS Warranty: ✓ 12 months or 1500 operating hours*

Precision Trenching with Tilt Couplers

When combined with a tilt coupler (tilt quick coupler), cable buckets significantly improve precision in narrow trenching applications. The additional tilt movement allows for accurate trench alignment without constantly repositioning the machine.

Especially in fiber optic installation, utility trenching, and test excavations, the combination of a cable bucket and a tilt coupler ensures cleaner trench lines, reduced rework, and more efficient workflows.
