Vertical drilling rig for confined spaces

Drilling rig KR 702-3

The powerful drilling rig, with separate Power Pack for vertical drilling applications in specialised foundation engineering - inside buildings and outdoors. An electric Power Pack (PP 55E) with 55 kW is available as an alternative to the Power Pack PP 117G (Diesel).

Compactness, performance and versatility.

Versatile drilling rig concept
The drilling rig can be used in a range of ways, for example for micropiles and mini piles, GEWI piles, for underpinnings, jet grouting work and uplift anchors.

Working in tight spaces
The KR 702-3 drilling rig is especially suited to work in confined spaces. For extremely compact dimensions, special attention was paid to the optimum design of the rig in terms of performance capability, load-bearing capacity and versatility. The KR 702-3 can be used in confined spaces, as it fits through doors which are up to 2400 mm high and 750 mm wide.

Because the crawler undercarriage can be projected to 1250 mm and has two-point support as standard, it provides excellent stability in all drilling situations. Each side of the crawler undercarriage and each support can be moved separately.

Operator Safety
With the tried and tested radio remote control with display, the operator can take up a safe working position around the drilling rig at all times. In accordance with the requirements of EN 16228, operator safety is ensured by the high functional safety of the control concept. An interlocking movable guard for moving parts in the drilling process is available.

High Performance
The drive of the external Power Pack (129 kW) is extremely efficient in relation to its compact size. The Power Pack complies with the EU Emission Standard Tier 5 for mobile drilling rigs. In combination of the PP 117G with the KR 702-3, the EEP (Energy Efficient Power) and power-sharing technologies are on board.

Electric alternative
With the PP 55E, it is possible to work without exhaust emissions and with reduced noise. The power-sharing technology and the two main pump circuits enable automatic and optimised power distribution according to actual demand.

Advantages

Ideal for cramped spaces

Underpinning, micropiles, injection and uplift anchors in confined working spaces.

Modularity

The drilling rig facilitates various configurations of the drill system, the drill mast design and power source.

Selectable main drive

Both the PP 117G and the PP 55E enable higher power utilisation thanks to power sharing technology.

Telematics

The optional KLEMM DataLink Air module for the transfer of machine and service data into the cloud.

Can be adjusted to the task at hand

  • Telescopic drill mast and modular drill mast kit
  • Diesel or electric Power Pack, each with Power Sharing technology
  • EEP on the PP 117G, e.g. automatic reduction of diesel engine rpm
  • Interlocking movable Guard (EN 16228)
  • Radio remote control and load-sensing hydraulics
  • Hydraulic drifters can be used
  • Installation of a cable winch in combination with a lateral sliding carriage

Details and options

Machine control

The Power Pack comes with a smart machine control system with a touch screen. Service functions, telemetry with DataLink AIR, EEP (automatic diesel engine speed adjustment) and power sharing (automatic power allocation of the two main pump circuits) are on board.

Details and options

Drive train

The drive train of the drilling rig is in a separate Power Pack. The core component of the PP 117G is a diesel engine, CAT C4.4 with 129 kW, which complies with exhaust emissions standard EU V.

Details and options

Radio remote control

The drilling rig can be operated from a safe distance using radio remote control.

Details and options

Quick couplers

The interface to the Power Pack is on the rear of the drilling rig.

Details and options
