An adjustable length tensioning member that comprises a rope, a first connector on the rope, a second connector on the rope, and a plurality of connection points between the first connector and the second connector is disclosed. The plurality of connection points have a diameter greater than a diameter of the rope. The rope may be passed through a socket coupled to a first crane component and one of the connectors on the rope is coupled to a second crane component. One of the plurality of connection points engages a seat on the socket to tension the rope between the socket and the connection point.

Adjustable length tensioning member

An intermediate suspension connection column segment designed for use in constructing a column which is supported by a suspension that includes a first end having a first connection configured to connect to a first adjacent column segment; a second end opposite the first end, the second end having a second connection configured to connect to a second adjacent column segment; and an intermediate suspension connection between the first connection and the second connection, the intermediate suspension connection configured to couple an intermediate suspension between the suspension and the column.

System and method for connecting a crane suspension assembly to a support column

A lift crane includes a carbody and movable ground engaging members mounted on the carbody. A rotating bed is rotatably connected to the carbody and includes a counterweight support frame including a rack coupled directly to a lower surface of the rotating bed. A boom is pivotally mounted to the rotating bed. A counterweight unit movement device is configured to move the counterweight unit toward and away from the boom. At least one auxiliary member includes a counterweight pad that is configured to not touch the ground during a pick, move, and set operation. A linear actuator is configured to adjust a distance that the counterweight pad is above the ground.

A gravity actuated crane stop for a crane is disclosed. The gravity actuated crane stop has a first connector at a first end configured to couple to a first crane member and an interface at a second end configured to interface with a second crane member. A gravity actuated mechanism is disposed on the body and has a first configuration in which gravity actuated mechanism disables the interface, and a second configuration in which the gravity actuated mechanism does not disable the interface. The gravity actuated mechanism is automatically changeable from the first configuration to the second configuration as the body is moved from a first orientation relative to a horizontal plane to a second orientation relative to the horizontal plane.
