Crane remote control device

Example embodiments relate to a lightweight crane. In one nonlimiting embodiment the crane is comprised of a telescoping boom having a first boom nested in a second boom which in turn is nested in a third boom. The first, second, and third booms may be made from aluminum to reduce the weight of the crane. The first boom may have a first open section and a second closed section wherein the open section is configured to accommodate a structural member to which an actuator is attached. The first and second booms have lower surfaces with inclined surfaces so that the first boom self-aligns with the second boom and the second boom self-aligns with the third boom.

Lightweight crane

Provided is a two-block sensing system (or device) that may be attached to an end of a lifting device, for example, a crane. The sensing device may include an A2B mount, a touch bar pivotally connected to the A2B mount, a link pivotally connected to the A2B mount, and a switch operatively connected to the touch bar so that if the touch bar is rotated with respect to the A2B mount, the switch becomes one of activated and deactivated.
