Helical pile driver

Professional pile foundation installation requires a tool that is highly reliable, generates sufficient force to drive the pile into any soil, and is also compact, easily transportable, and self-contained. A helical pile driver perfectly meets these requirements.

It consists of a hydraulic gearbox with a removable stop that directly rotates the pile, and a mobile hydraulic unit connected to the gearbox via flexible hoses.

The gearbox is mounted on the pile using an adapter of the appropriate diameter. A stop rod is connected to it, preventing the mechanism from rotating around its axis. Typically, a starter pile is driven in slightly to the side first, which is used as a stop during installation of the first pile in the pile field. Next, adjacent already driven piles are used as stops, for which a special attachment is placed on them (it is visible in the video, and supports the rod). A gasoline-powered hydraulic unit pumps hydraulic fluid through the hoses, transmitting force from the hydraulic pump to the gearbox. It features adjustable speed and direction of rotation. Torque, depending on the design, ranges from 7,000 Nm to 9,000 Nm, or even higher.

A portable hydraulic pile driver is used to install pile foundations in the vast majority of cases:

- under fences, gates (sliding and swing), and wickets;

- under gazebos, verandas, summer kitchens, and sheds;

- under garages, utility buildings, sheds, and workshops;

- under timber houses, SIP panels, frame houses, and other types of houses;

- under greenhouses and hothouses (both garden and industrial);

- under docks, piers, and marinas;

- under pedestrian bridges, decks, and stairs;

- under flagpoles, lighting masts, and power line supports; - for open (aboveground) pipelines;

- for industrial facilities (tanks, towers, hangars, and warehouses);

- for security posts, barriers, advertising media, bus stop shelters, and much more.

Larger facilities requiring higher productivity are typically serviced by tracked or pneumatic pile drivers.
