Abstract

A system and method for retaining a linear actuator on a crane component such as a mast is disclosed. In the system a retaining mechanism is mounted on either a body of the linear actuator or the crane component and a catch is mounted to the other of the body or the crane component. Retraction of a rod of the linear actuator causes a cap on the rod to contact the retaining mechanism, which causes the retaining mechanism to move into a latched configuration securing the linear actuator.

Claims (4)

1. A method for retaining an assist hydraulic cylinder coupled to a live mast, the method comprising:

positioning the live mast having an assist hydraulic cylinder to have a minimum angle greater than sixty degrees relative to the horizon, with a rod extended from the hydraulic cylinder;

retracting the rod until a rod end contacts a latching mechanism; and

further retracting the rod end causing the latching mechanism to engage with a catch coupled to the live mast, wherein causing the latching mechanism to engage with the catch comprises moving a pin parallel to the hydraulic cylinder to position the catch between a portion of the pin and a portion of the hydraulic cylinder.
