Abstract
The invention relates to a pile driver for driving piles into ground. The pile driver comprises a body, a vibrator unit, a primary first arm and a primary second arm, both being pivotable about a primary axis; and a secondary first arm and a secondary second arm, both being pivotable about a secondary axis, which is parallel with the primary axis. The pile driver comprises an actuator or actuator arrangement for pivoting the arms. A first part of the primary first arm is provided with a primary first attachment for attaching an adapter of an adapter arrangement. An adapter for use with the pile driver. An arrangement comprising the pile driver and two adapter arrangements each comprising at least an adapter.
Claims26
An arrangement comprising:
- a pile driver for driving piles into ground, the pile driver comprising
- a body attachable to a power tool,
- a vibrator unit attached to the body,
- a primary first arm and a primary second arm, the primary first arm and the primary second arm being pivotable about a primary axis, the primary axis being arranged in a first direction,
- a secondary first arm and a secondary second arm, the secondary first arm and the secondary second arm being pivotable about a secondary axis, the secondary axis being parallel with the primary axis,
- an actuator or actuator arrangement for pivoting [a] at least one of the primary first arm and the primary second arm and [b] at least one of the secondary first arm and the secondary second arm, wherein
- a first part of the primary first arm is provided with a primary first attachment for attaching an adapter suitable for gripping an object to be driven with the pile driver
- the primary axis is arranged a first distance apart from the secondary axis, and
- a tip of the first part of the primary first arm is arranged a second distance apart from the primary axis such that a ratio of the second distance to the first distance is equal to or less than 1.5;
- the arrangement further comprising:
- a primary adapter arrangement for gripping a first object to be driven with the pile driver, the primary adapter arrangement being configured to be fixed both to the primary first attachment of the primary first arm and a primary second attachment of the primary second arm,
- a secondary adapter arrangement for gripping the first object such that at least a part of the first object is arranged in between the primary adapter arrangement and the secondary adapter arrangement, the secondary adapter arrangement being configured to be fixed both to a secondary first attachment of the secondary first arm and a secondary second attachment of the secondary second arm,
- a primary stiffener configured to couple the primary first arm and the primary second arm such that the primary first arm and the primary second arm pivot together, and
- a secondary stiffener configured to couple the secondary first arm and the secondary second arm such that the secondary first arm and the secondary second arm pivot together;
- wherein the primary adapter arrangement comprises:
- a first mount configured to be fixed to the primary first attachment, and
- a second mount configured to be fixed to the primary second attachment.
