Electrification pile driver
Energy - System integration - Mobile control
A construction machine for driving foundation piles into the ground.
Background
To limit climate change, increasingly stringent emissions requirements are being imposed on vehicles, including construction equipment. This is also increasingly emphasized in works tenders.
The work must be done with emission reduction to be considered for award. In addition, several competitors already offer electric machines in their lineup.
Challenge
In general, the goal of electrification is to allow machines to operate with fewer emissions. It is expected that pile-driving machine owners will be able to perform jobs that offer emission benefits. This covers the extra effort and higher cost of electrically powered machines compared to conventional diesel machines. Despite the high power, the machine should be deployable for an average 9-hour working day without being connected to the grid or external power supply.
Solution
Using HSC's HSC1500A-3 electrified zero emission base machine saves on engineering costs. Through the development of a conversion kit, the functionality of the base machine is optimized for pile driving functionality. The conversion kit was developed to replace the diesel engine and related components with an electric motor, battery system and additional electrification components. The electric motor is coupled to the existing hydraulic pump unit. This means that all hydraulic functions of the machine are controlled by the originally installed control system. An additional display is mounted in the cab to control the electric driveline. To charge the battery system, two CCS2 inlets are provided that allow starting, stopping and charging current to be controlled via the adjacent display.
