From Pile Breakers to Bailers: A Guide to Essential Piling Equipment
August 12, 2026
How Different Types of Piling Equipment Support Safe and Efficient Construction
Piling is foundation work. When surface soil is too soft, too wet, or too unstable to carry a structure's load, piles carry that load down to stronger ground or rock instead. Get the piling wrong, and everything built on top of it could be at risk.
This guide runs through some of the most commonly used piling equipment and the role each one plays on-site, from drilling the hole to driving the pile and keeping the excavation stable while the work is done. It's general information only. Confirm equipment selection against your site's geotechnical report and engineering requirements.
Why the Right Equipment Matters
Ground conditions, access, pile depth, and pile type all affect which machine or attachment is right for the job. Mismatched gear leads to slower drilling, poor pile placement, and unnecessary strain on the machine and crew.
At Pilehire, we hire out piling and drilling equipment to contractors and engineers across New Zealand. The breakdown below reflects the gear we supply and support day to day.
Drill Rigs for Every Site Condition
Drill rigs bore the holes that piles are placed into. The right rig depends on depth, torque, and access:
- Compact rigs, such as the FY10 and FR35, suit tight or restricted sites where a smaller footprint matters more than raw depth.
- The KR50 is rated to 50kN torque for depths of 20 metres, suited to deeper foundation work.
- For reinforced foundations or harder ground, the FR130X offers 130kN torque and compatibility with CFA and displacement drilling.
Matching torque and depth capacity to the ground conditions helps keep a bore straight, on size, and on schedule.
Pile Drivers and Vibro Hammers
Once a pile is ready to go in, it's driven or vibrated into place:
- Drop hammer attachments, from 3 to 30 tonnes, deliver the high-impact force needed to drive piles, posts, and beams.
- Vibro hammers, fitted to excavators from 10 to 60 tonnes, use high-frequency vibration to reduce ground resistance, suiting sheet piles and driven columns.
- Excavator plate compactors handle post and compaction work, while breaker drivers (modified rock breakers fitted with a cub spear) drive posts into ground too hard for a standard hammer.
Crane Mount Vibros for Casings and Sheet Piles
On larger jobs, crane mount vibros handle vibration work that excavator-mounted units can't reach:
- Mainly used to vibrate casings and sheet piles into the ground.
- Also, handle compaction and extraction when it's time to pull them back out.
- Our range spans several sizes, from the ESF23, our smallest crane mount vibrator, through to larger units, so we can match the vibro to the pile size and site setup.
Sheet Piles and Casing for Ground Support
Sheet piles and pile casing hold the ground back while piling and excavation work is underway:
- Sheet piles, available for temporary and permanent retaining, help stabilise excavations when specified and installed correctly for the site.
- Pile casing (also called a caisson) lines boreholes to maintain their integrity while drilling, particularly in soft or waterlogged ground.

Piling Platforms for Safe Working Surfaces
Heavy plant on soft or uneven ground needs a stable base to work from. Piling platforms provide a load-rated surface for drill rigs, cranes, and pile-driving equipment, and are standard on soft or previously disturbed ground. Each platform is inspected and maintained as part of our standard hire process.
Other Piling Equipment on Site
Other piling equipment we supply includes:
- Pile breakers, used to break down piles during demolition or clear pile heads after an over-pour.
- Pile clips (ground release shackles), certified for lifting casings, sheet piles, and UC sections. Crews release them from the ground, so there's no need for a man cage or ladder.
- Down-the-hole grabs, lowered by crane to pull rocks and boulders out of a bore.
- Bailers, used to suck water out of a hole quickly, especially on large-diameter bores.
- Lifting cages, in 2, 4, and 8-man configurations for crane and forklift use.
