Mast post driver
Fitted with a sliding weight on a vertical mast, this post driver offers robust striking force in all working conditions. It is mainly used on an inter-row tractor, as it is mounted on a chassis with a 3-point linkage. However, this post-driving system presents significant risks of accidents due to its sliding weight system, unlike percussion equipment.
Component parts
Drive for the driving part
Two drive systems are available:- Either via the tractor's hydraulic pump.
- Or by the power take-off (540 rpm), which drives a hydraulic power unit to ensure a constant flow for driving in the stakes.
The weight
The stakes are driven by a weight that slides on a mast. The weight's momentum of around 150 kg enables the head of the post to be driven flat into the hardest soil.The post clamp
The posts are held in place before and during work by a post clamp. This ensures that the post is held in place and remains plumb. On some tools, the weight cannot be released while the post clamp is open.Use and settings
Tilt
The mast is tilted mechanically, but a hydraulic option is available for correcting plumb.Offset
In most cases, the tool is offset mechanically, but a hydraulic system is available as an option.The hydraulic offset and mast tilt options offer real advantages in terms of time saving and efficiency.
