Coupler device for helical pile
A helical pile coupler assembly is operable to be drivingly attached to a helical pile section and is rotatable with the helical pile section about a coupler axis. The coupler assembly is operable to transfer torque supplied by a rotating drive to the helical pile section as the helical pile section is driven through the ground. The coupler assembly includes male and female couplers that define a projection and a socket, respectively. The male and female couplers are shiftable relative to each other along the coupler axis into and out of a mated condition where the projection and socket are mated so that the couplers drivingly engage each other and are configured to transfer torque therebetween. The socket is shaped to removably receive the projection in the mated condition. The projection presents a projection surface that extends along the coupler axis and defines a projection profile with only three radial lobes, with each of the lobes extending radially outwardly relative to the axis in corresponding radial directions.
