Electric Actuation For Crane Pinned Boom

A crane comprising:

• a carrier;
• a superstructure mounted on the carrier, the superstructure comprising a telescoping boom having a base section and a plurality of telescope sections;
• a boom actuator system comprising a telescoping member;
• a lock head actuator on the telescoping member, the lock head actuator having an actuator arm configured to move in a first direction and a second direction opposite to the first direction;
• an operating plate connected to the actuator arm and configured to move with the actuator arm, wherein the operating plate and actuator arm are moveable in the first direction from a retracted position to a neutral position and from the neutral position to an extended position;
• cylinder pins operably connected to the operating plate by a pin linkage, wherein movement of the operating plate from the retracted position to the neutral position causes the cylinder pins to move from a pin retracted position to a pin extended position;
• and
• section lock arms operably connected to the actuator arm by a lock arm linkage, wherein the movement of the actuator arm from the neutral position to the extended position causes the section lock arms to move from a locking position to an unlocking position,
• wherein the actuator arm is spaced from the lock arm linkage moving from the retracted position to the neutral position and drives movement of the lock arm linkage moving from the neutral position to the extended position.
