OPERATING PROCEDURES - SCREW ANCHORING (PILE/PIER)
1. Installation is to be performed by a trained and/or certified installer.
2. Connect the manufacture’s approved adapters to the Planetary Drive head. As the pressure builds & the torque increases, install
the pile in one continuous motion until the desired depth and torque is achieved.
3. Install pile/pier with a continuous motion. The rate should match the pitch on the pile. Make sure to apply just enough downward
pressure to help the advancement of the pile into the ground, but not too much that you are driving or drilling the pile into the
ground.
High Powered PD and SD Digga drives are only fitted with an ECV - Energy Contol Valve (Patented) as an “option” and designated
as “SV” (see page 6). During the screw anchoring process energy builds up in the pile/pier and when the operator stops installation
when torque is reached, the pile/pier temporarily ‘flicks’ back or rotates back forcing energy up the pile/pier back up through the
gearsets and into the motor momentarily turning the motor into a pump. The ECV is designed to protect the motor from this action and
essentially grabs the oil and gently bleeds it back down the hydraulic lines. The sound it makes is a gentle ‘swoosh’, this is how you
know the valve is working.
N.B Ineffeciences occur with machinery that can reduce the torque output, such as heat, cold, age of machine etc... It is therefore
highly recommended that Torque monitoring equipment to keep record of the torque and pressure is installed. Contact Digga or your
local Digga Dealer for further information regarding torque monitoring options.
IT IS THE RESPONSIBILITY OF THE INSTALLER TO CORRECTLY CALCULATE, PLAN AND EXECUTE THE INSTALLATION OF
THE PIERS TO THE NOMINATED TORQUES REQUIRED. DIGGA DOES NOT ACCEPT ANY LIABILITY OR CONSEQUENTIAL
LOSS THAT IS INCURRED FROM INCORRECT INSTALLATION, OVER TORQUING OR UNDER TORQUING OF PILES.
