Abstract
A log pusher comprising a frame, a reception bed attached to the frame and a single step assembly moving up and down with regard to the reception bed. The single step comprises a resilient member for absorbing and/or reducing vibrations associated with logs impacting the log pusher. A method to reduce vibrations associated with logs impacting a log pusher is also provided. The pusher may also be replaced in a log production line using a crane or any other similar equipment.
Claims19
A single step log pusher for absorbing vibration from logs, comprising:
- a frame;
- a reception bed attached to the frame to receive a plurality of the logs;
- a drive system;
- a single step assembly driven by the drive system and configured to move up and down about the reception bed comprising:
- a sliding member movable upwardly and downwardly by the drive system;
- and
- a guiding assembly guiding movement of the sliding member comprising at least one resilient member configured to reduce vibration from the movement of the received logs.
A single step log pusher comprising:
- a frame;
- a reception bed detachably attached to the frame to receive a plurality of the logs;
- a drive system;
- and
- a single step assembly driven by the drive system and configured to move up and down about the reception bed, the single step assembly being detachably attached to the frame.
A method to reduce vibrations associated to operation of a log single step device comprising:
- receiving a plurality of the logs to form a line;
- upwardly pushing a first of the logs in line;
- and
- absorbing vibrations associated with the pushing of the logs or other vibrations created by the reception of the logs.
A method for replacing a component of a log pusher comprising:
- detaching a component from the log pusher;
- attaching a lift system to an attachment member of the detached component;
- lifting the attached component;
- replacing the component with a replacement component using the lift system;
- and
- connecting the replacement component to the log pusher.
