An interlock system includes first and second connectors for connecting a boom section to a boom. A first cover is provided for covering an actuator for actuating a first connector when a second connector is withdrawn from a position for connecting the boom section to the boom. A first block may also be provided for blocking a first receiver in an operative condition to prevent the first connector from entering the first receiver. The connector may be adapted for movement along an insertion axis corresponding to a first receiver on the boom section and a second receiver on the boom, and an actuator may be provided for advancing or retracting the connector, the actuator extending generally parallel to, but offset from, the connection axis. Related methods are also disclosed, as is an axially offset actuator for actuating one or more of the connectors for connecting the boom section to the boom.
