Petrol-powered pile driver, Ø 20–80 mm, for wooden/metal piles – "Joey"

"Joey" pile driver with air-cooled 4-stroke petrol engine

The "Joey" pile driver is an efficient and modern piece of equipment for the quick and easy driving of wooden, metal and concrete piles up to a diameter of 80 mm. It enables professional work on building sites, in agriculture, event technology and many other applications. Thanks to its low weight and compact dimensions, it is highly versatile; yet it still offers sufficient power for fast and precise results.

The operator’s workload is reduced thanks to the modern design, ergonomic construction and vibration-damped handles.
All the machine’s controls are integrated into the combination switch in the operating handle, which simplifies handling and makes operation intuitive.
The pile driver’s drive motor, with an output of 1 kW / 1.36 PS, generates a powerful impact energy of up to 55 joules at a maximum frequency of 1,350 impacts per minute. The motor can be started easily using a pull cord. The large fuel tank and low fuel consumption allow the machine to be used for longer periods without the need to refuel.
The built-in four-stroke engine offers various advantages over the commonly used two-stroke engines: quieter and lower-emission operation, as well as a longer service life and low maintenance requirements.
The cast aluminium gearbox housing and the robust engine ensure the machine’s stability and durability.

The accessories and tools supplied, together with the operating instructions, ensure that you will be able to use the pile driver safely and without any problems. The warranty and service provided by Kernlochbohrer GmbH ensure that you will enjoy using the machine for many years to come.

Note on commissioning
The machine is supplied by Kernlochbohrer with engine oil already filled. Before starting the engine for the first time, the engine oil level must be checked as a safety precaution!

Guidance on driving piles with a pile driver
Different ground conditions can affect the driving process and the stability of the driven piles. There are a number of important aspects to bear in mind here:

Soil type
The soil type has a significant influence on the driving process. Loamy soil offers greater resistance, whilst sandy soil is generally less resistant. Clayey soil is characterised by high cohesion, which can lead to increased resistance during driving.

Soil moisture
Soil moisture also plays an important role in the driving process. Wet soil increases the resistance encountered by the pile, whilst dry soil offers less resistance. If the soil is too wet or muddy, it can be difficult to drive the pile, as this leads to increased frictional resistance.

Soil conditions at depth
It is very important to take soil conditions atdepth into account, as these can often differ from the surface soil layers. It is possible that the upper soil layers consist of loose material such as sand, whilst firmer clay or even rock may be present below. These differences can lead to uneven driving and affect the stability of the pile.

Groundwater level
The groundwater level is another factor influencing the driving process. A high groundwater level increases the resistance encountered when driving piles. The presence of water can also loosen the soil and lead to reduced stability of the driven pile.

Pile type and dimensions
The influence of soil conditions also depends heavily on the pile type and its dimensions. Different pile materials, such as timber, steel or concrete, each have different mechanical properties and therefore react differently to various ground conditions. It is important to select the correct pile type in accordance with the ground conditions to ensure optimum load-bearing capacity and stability. The dimensions of the pile also play a role, as they influence resistance and load-bearing capacity.

Soil investigation
A comprehensive soil investigation prior to the driving process is crucial for assessing soil conditions and identifying potential difficulties or risks. This investigation enables an informed decision to be made regarding the driving process, ensuring optimum stability and durability of the driven piles. Assessing the ground conditions enables appropriate measures to be taken to address potential challenges, such as the use of specialised piling techniques, adjustments to the driving process, or the selection of suitable pile materials. A thorough soil investigation is an essential part of a successful pile driving process and helps to identify potential problems at an early stage and find suitable solutions to ensure the stability and safety of the structure.
