MOVAX Drill Heads
MOVAX Piling drills are excavator-mounted, telescopic/kelly bar-type auger drive attachments explicitly designed for cast in-situ (concrete) pilings and other soil removal tasks.
They are especially suitable for work in confined spaces while still being good at reaching over obstacles. The telescopic/kelly bar design keeps the drill height low and allows working on sites with limited headroom without compromising on drilling depth.
MOVAX piling drills are operated by transferring the torque and crowd force from a rotary drive tool to the drilling tool. MOVAX utilises two different designs: a telescopic design (TAD-models) and a kelly bar design (KB-models).
Kelly Bar Piling Drill Technology
MOVAX kelly bar-design piling drills utilize interlocking-type kelly bars which have drive ribs welded with lock devices utilized to transfer the maximum amount of torque to each section. The standard kelly bars are manufactured as a fully lockable system with a mechanical locking mechanism between each element, the outer bar and the rotary drive.
The kelly-bar design piling drill can also be used for cased drilling.
Telescopic Piling Drill Technology
MOVAX telescopic-design piling drills are cylinder/chain driven. The piling drills consists of one or two moving sections.
Features ofMOVAX Piling Drills
Excavator-Mounted
- Suitable for 20-50 ton excavators.
- Utilizes the hydraulic power and lifting capacity of the excavator or rail roader.
- Designed to work on any and all wheeled and crawler-type excavators and rail roaders by utilizing and commanding the standard auxiliary hydraulics and/or by connecting to the electronic control of the excavator.
Telescopic
- Light weight, telescopic type piling drills with a maximum drilling depth of 9 meters intended primarily for basic rail roaders and smaller excavators.
Kelly Bar
- Heavy duty, kelly bar type piling drills with a maximum drilling depth of 20 meters intended primarily for heavy duty rail roaders and large excavators.
MOVAX Modular System
- Versatility based on the MOVAX Modular System™ which enables the use of the same unit for a wide range of different piling requirements.
- The modular system includes a wide range of lead augers in different sizes and for different soil conditions.
- Service winch (optional, KB-models only)
- Casing adapter and cardan joint for cased drilling
