Abstract
There is provided a piling hammer comprising an electric drive assembly configured to generate linear movement of a mover connected to a ram block for striking a pile, a processor operatively connected to the electric drive assembly and configured to determine a recoiled kinetic energy from striking the pile using a ram block connected to a mover of the electric drive assembly, determining at least a portion of the determined recoiled kinetic energy for regenerative braking of the mover to a peak position, control the electric drive assembly to decelerate the mover to the peak position based on the determined at least a portion of the determined recoiled kinetic energy.

A piling hammer comprising:
- an electric drive assembly configured to generate linear movement of a mover, the mover being connected to a ram block for striking a pile;
- a processor operatively connected to the electric drive assembly and configured to:
- determine a recoiled kinetic energy from striking the pile using a ram block connected to the mover of the electric drive assembly;
- determine at least a portion of the determined recoiled kinetic energy for regenerative braking of the mover to a peak position;
- control the electric drive assembly to decelerate the mover to the peak position based on the determined at least a portion of the determined recoiled kinetic energy.
A method for striking a pile by a piling hammer comprising:
- determining a recoiled kinetic energy from striking the pile using a ram block connected to a mover of the electric drive assembly;
- determining at least a portion of the determined recoiled kinetic energy for returning the mover to a peak position after striking the pile;
- controlling the electric drive assembly to decelerate the mover to the peak position based on the determined at least a portion of the determined recoiled kinetic energy.
A non-transitory computer readable medium comprising program instructions for causing an apparatus to:
- determine a recoiled kinetic energy from striking a pile using a ram block connected to a mover of an electric drive assembly;
- determine at least a portion of the determined recoiled kinetic energy for returning the mover to a peak position after striking the pile;
- control the electric drive assembly to decelerate the mover to the peak position based on the determined at least a portion of the determined recoiled kinetic energy.
A pile driving apparatus comprising a piling hammer comprising:
- an electric drive assembly comprising a mover connected to a ram block for striking a pile;
- a processor operatively connected to the electric drive assembly and configured to:
- determine a recoiled kinetic energy from striking the pile using a ram block connected to the mover of the electric drive assembly;
- determine at least a portion of the determined recoiled kinetic energy for regenerative braking of the mover to a peak position;
- control the electric drive assembly to decelerate the mover to the peak position based on the determined at least a portion of the determined recoiled kinetic energy.
