Utility
Crane
11 Feb 21
There is provided a crane including: a telescopic boom having an inner boom element and an outer boom element; a telescoping actuator that displaces the inner boom element or the outer boom element in the telescoping direction; a first coupling member that releasably couples the telescoping actuator to one of the boom elements; a second coupling member that releasably couples the pair of boom elements to each other; an electric drive source provided at the telescoping actuator; a first coupling mechanism that displaces the first coupling member or the second coupling member on the basis of motive power of the electric drive source, thereby switching a coupled state and a non-coupled state of the members that are releasably coupled by one of the coupling members; and a position information detection device that detects information relating to the position of one of the coupling members on the basis of output from the electric drive source.

Crane
11 Feb 21
This crane is configured by being provided with: a telescopic boom having an inside boom element and an outside boom element that overlap each other in an extendable and contractible manner; an extension/contraction actuator that displaces one boom element among the inside boom element and the outside boom element in the extending and contracting directions; at least one electric drive source provided in the extension/contraction actuator; a first coupling mechanism that operates on the basis of power from the electric drive source and that switches between the coupled state and the uncoupled state of the extension/contraction actuator and one of the boom elements; and a second coupling mechanism that operates on the basis of power from the electric drive source and that switches between the coupled state and the uncoupled state of the inside boom element and the outside boom element.

Outrigger device
26 Jan 21
An outrigger device that is mounted on a vehicle and can switch between a usage state and a storage state includes: a lateral outrigger that extends in a vehicle width direction of the vehicle; a vertical outrigger that is extendable and is rotatably coupled to a leading end portion of the lateral outrigger; a first coupling member that constantly couples a first part of the vertical outrigger to the lateral outrigger and serves as a rotational center of the vertical outrigger; a second coupling member that can switch between a first state where a second part of the vertical outrigger is coupled to the lateral outrigger and a second state where the second part is uncoupled from the lateral outrigger; a conversion mechanism that converts a retraction of the vertical outrigger into an upward rotation of the vertical outrigger; and a safety device that prohibits an operation of the conversion mechanism in the first state and permits the operation of the conversion mechanism in the second state.

Utility
Crane vehicle
26 Jan 21
A device executes an actuation control process of causing the actuator to execute actuation corresponding to an operation signal in response to an output of the operation signal, a stopping process of stopping the actuation of the actuator in response to an output of a first over-winding signal or a second over-winding signal during the actuation control process, and a notification process of notifying whether or not the identification signal has already been output from an over-winding sensor in response to the first output of the operation signal corresponding to specific actuation of reducing a suspension length.
