Optional Extras

ROCK SPIKE A rock spike can be supplied to act as a pilot for the post. This can be gripped by the standard jaws. Standard size 60mm diameter 1m long
POST TWIST Specially designed to be used in conjunction with position critical posts the twister allows the operator to rotate the posts through 15 deg in each direction while driving in. This is used extensively on solar farm work to keep the tops in the correct orientation
GROUND DIBBER To create a concrete back fill hole and leave the central bar in place. A 250 x 150mm compacted void is left in the ground and either a length of re-bar or angle is let in the ground. The advantages are no soil away and a compacted hole prepped for cement
CUSTOMISED POST CLAMPS A wide range of clamps are available to suit posts of all shapes, sizes and material. With a drawing of the top of the post the jaws will be manufactured to suit
FLOW CONTROL OPTIONAL For hard to reach jobs a larger machine is sometimes necessary. To protect the motor and seals it can be necessary to add a flow control option to prevent internal damage.
