ZetKO manufacture and supply telescoping, furnance wrecing equipment for all standard wheel-base, or tracked hydraulic excavators. The machines are based on the "Zimmermann-System", which has been used throughout the world for over 20 years. The equipment is subject to continuous up-dating, in close co-operation with end-users.

ZetKO telescoping booms are designed to meet the extreme demand of the steel mill environment, efficiently cleaning and wrecking, hot or cold runners, ladles, electric -arc furnance and converters. With an optional attachment, the equipment is also suited for taphole drilling and reaming.

ZetKO telescoping booms can be positioned and aligned with great precision, thus saving plant, accessories, time and money.

In tunnelling applications, the highly mobile ZetKO telescoping booms are used to chisel and ream tunnel profiles, significantly reducing down-time of on-going traffic.

The geometry of the equipment is comparable to that of the human arm, with an added 360° rotation facility beneath the elbow.
Maximum stroke is 14.5m.
ZetKO telescoping booms consist basically of a rotating, outer base frame with an inner, telescoping extension.
The base frame of the equipment is attached to the excavator. A ring main bearing on the outer base frame and a hydraulic swivel assures 360° continuous rotation.
The inner, telescoping extension is guided by generously dimensioned rollers in the base frame. These ensure low wear and allow for even and perfect transmission of forces. The tool cylinder is located safely inside the head
section of the extension.

The additional hinge of ZetKO booms type WB7000A and WB 12000A significantly increase the operational reach of the equipment. This also reduces the overall height of the machine, a helpful feature when it comes to moving about in low headroom conditions.
