Windowless / Dynamic Sampler

Occupying a small footprint, this compact and extremely versatile rig is capable of a range of site investigation techniques in areas of restricted space and difficult access, including disturbed and undisturbed sampling, SPT and dynamic probing.

Mounted on a small crawler unit, the rig is easily transportable and simple to manoeuvre through tight spaces, causing very little disturbance to its surroundings.

Features include:

Disturbed and undisturbed sampling, SPT and dynamic probing.
Compact crawler mounted design.
2-piece drop hammer incorporated in mast assembly for recovery of casing and sampling tools.
Mast assembly can be detached for remote operation.
Hydraulic tilting undercarriage allows operation on inclined slopes of up to 30 degrees from horizontal.
Deck area with storage capacity for all required drilling tools.
Rotary concrete coring head available as an option. Useful when concrete and tarmac overlie the area to be sampled.
3 cylinder 19 HP diesel engine providing increased power and smoother operation. Easy to access for simple maintenance.
