Auger Drive Units

The ADU range of Erkat auger drive units are designed for use on excavators from 3 to 50 tons.

ADU auger drive units are almost indestructible, high performance drives that have proven themselves many times while successfully drilling holes in medium hard limestone with 60 MPa compressive strength.

Drilling with Erkat auger drive units

If the auger string is not vertical during drilling with the ADU, strong bending forces are exerted on the hexagonal drive shaft. It is therefore important that care is taken to maintain the auger in a vertical position while drilling to avoid these bending stresses.

EBK-F

Suitable for soil class 1 – 2 (such as less cohesive, medium dense sands, soft to stiff clay, marl and similar wet, fine and mixed graded grounds)

EBK-RF drill bit

EBK-RF

Suitable for soil class 3 – 4 (such as lime, chalk, dry clay, dry marl and similar cohesive dry ground types)

EBK-R3 drill bit

EBK-R3

Suitable for soil class 5 – 6 (such as medium to high dense layers, light cohesive sand/gravel mixture, compacted fine / medium gravel, fracturable soft rock layers)

EBK-R3 HD drill bit

EBK-R3 HD

Suitable for soil class 5 – 7 (such as compacted gravel, fractural rock layers up to medium hard fractured rock, max. 60 MPa)

ER range overview

ER range

The transverse drum cutter is ideally suited for trenching, tunneling, special foundation work, demolition and for soil mixing. The operating characteristics of Erkat special drum cutters allow them to be used in noise and vibration sensitive areas.

ERC range overview

ERC drum cutter range

The ERC range from Erkat represents a new generation of revolving rotary drum cutters that extends significantly the number of applications suitable for transverse drum cutters.

ERL range overview

ER-L range

Longitudinal drum cutters are driven by a powerful radial piston motor creating extremely high cutting forces. The robust cutter drums together with their secure fixing method enable them to operate in the most demanding conditions. Consoles can be supplied with different lengths to suit a variety of applications.
