What is pile breaker?

Pile breaking involves demolition of old concrete piles in order to make way for driving of new piles and subsequent building of new structures. Demolition of concrete piles is quite a challenge due to the presence of steel reinforcement bars and using conventional methods of can be quite cumbersome and time-consuming.

In construction project involving pile foundations, one of the most cumbersome and time consuming activity is the crushing of top portion of the Castin-Situ Piles /Precast Piles as required to remove the weak top concrete and expose the reinforcement to be used for further construction. Pile breakers solve the problem by crushing such overhangs in a speedy and precise way. The reinforcement bars are left intact facilitating the rebuilding work. The breaking down of concrete piles is an essential part of the construction process and a subject that is often not given sufficient early thought in the planning of the piling works.The adoption of a suitable pile breaking method can result in financial savings for the project and most importantly will address and reduce potential health and safety issues in relation to this phase of the works.

Installation and operation instructions

Determine and install the corresponding number of modules and lifting devices, and the pile cutter can be used when it is delivered to the customer, saving the customer’s initial operation time. In engineering construction, mobile excavators are often used as power sources. Remove the excavator bucket, hang the pile cutter’s lifting chain at the connecting shaft between the bucket and the boom, and mechanically combine the two equipment together. Then connect the excavator’s boom hydraulic oil circuit to the pile cutter’s cylinder oil circuit through a balance valve to drive the pile cutter’s cylinder group to work.

How to connect pile breaker to excavator ?

1. Please find the third picture (Red rectangle part, you have to find it in local market, because different excavator connect method is little different).

2. Buy the part in a red rectangle, fit it to excavator and connect it with part in a green rectangle. (Please check below picture).

3. See below picture (connector on cylinder body, it connects input line, the other is output line).

4. Below is hose in another size.

Operation precautions

1. Do not approach the pile cutter in operation. Concrete will fall when cutting piles. Before approaching the pile cutter, you must notify the power source operator to stop the operation!
2. Check whether the hydraulic oil pipes and hydraulic joints are tightened before cutting piles. When the hydraulic pipes are tightened, the oil pipes and joints with oil leakage must be replaced!
3. The working device part must not be knocked or damaged by external force, which will affect the use of the working device and the life of the whole machine. The working device must be cleaned frequently after cutting piles!
4. No one should be within the rotation range of the construction machinery during the pile cutting operation, otherwise it will cause serious casualties!
5. During transportation, site transfer and operation, no external force should be used to knock or press the oil cylinder! When the construction is stopped, the dirt, broken sand, etc. of the oil cylinder accessories should be removed frequently to keep the area around the oil cylinder clean!
6. Hydraulic pipes and pipe joints must not be knocked or pressed by external force during transportation and operation at the construction site! Especially when operating, if there are pieces of concrete falling on the hydraulic parts, remove the concrete on the hydraulic parts when not in operation, keep the hydraulic parts from being deformed by external forces, and keep the area around the hydraulic parts clean!
7. When working, please ensure that the drill rod of the round pile cutter is tangent to the pile (the drill rod of the square pile cutter is at a vertical angle to the pile) to avoid the drill rod of the pile cutter and the pile forming an angle, which may damage the machine!

Maintenance Instructions

Hydraulic pile cutters are easy to repair and maintain. When the pile cutter works continuously for 1 month or cuts 1,000 piles, stop the operation and check whether all parts of the pile cutter are intact?

First check whether the lifting device is damaged or cracked, especially the lifting chain and chain shackle. Carefully check each part. If there is damage or crack, please replace it immediately! Check the working device, especially the drill rod and hydraulic parts!

The drill rod is a direct working part. When a certain workload is reached, it is easy to break. Pressurize and extend all the drill rods. Check each drill rod one by one. If there is damage or crack, please replace it immediately. If it is intact; each hydraulic part should also be checked one by one. If there is damage or crack, update it immediately.

Key points of daily maintenance

After completing work every day, the air pump air pipe needs to be aligned with the gap between the guide flange and the drill rod to clean the air inward (as shown in the figure below). This will blow out the dust entering the guide flange, which is good for the maintenance of the drill rod, guide flange and cylinder.
