Embodiment Construction

[0161] figure 1 A crane 1 according to the invention is shown comprising a mast M extending substantially in a vertical direction V (perpendicular to the ground S on which the mast M is arranged) and supporting a jib F which F is substantially horizontal and articulated in rotation relative to mast M.

[0162] Thus, the mast M has a foot P located near the ground S and a top SO located near its articulation with the jib F.

[0163] The crane 1 also comprises a cab C fastened to the top SO of the mast M or to the jib F and in which the driving device 2 is arranged.

[0164] This drive device 2 is arranged to be manipulated by the crane operator present in the cab C in order to perform various maneuvers of the crane. In a variant not shown, the drive is a radio-controlled drive for remote actuation by the crane operator.

[0165] For example, the crane operator can drive the horizontal pivotal movement of the boom F relative to the mast M through the drive device 2, or drive ...

Abstract

The invention provides a maintenance method for maintaining a crane (1), said crane comprising a monitoring system linked to a drive device (2) arranged to allow a plurality of motorized drives, said maintenance method being characterized in that it implements the following steps: a step of changing a configuration by means of a maintenance control system in order to switch said crane into a maintenance configuration, wherein the motorized drive is initially blocked by the monitoring system; a selection step for selecting, by means of a maintenance module (5) connected to the monitoring system, a maintenance maneuver, the drive of which is initially blocked, from among the plurality of maneuvers; an unlocking step in which the monitoring system unlocks the drive of the maintenance maneuver; and a step for driving the maintenance mover by means of a drive device.

Description

technical field [0001] The invention relates to a maintenance method for maintaining a crane. [0002] The invention also relates to a crane and a maintenance assembly suitable for carrying out this maintenance method. Background technique [0003] In the field of cranes, such as tower cranes having a mast supporting a boom and adapted to move a load, it is often necessary to perform maintenance maneuvers on active cranes already assembled and installed at the site of operation. [0004] Such maintenance operations take place, for example, in the event of technical problems, with the aim of repairing and refurbishing the crane, thus preventing it from operating, or with the aim of preventing the crane from being damaged, leading to a reduction in its operational performance. [0005] In order to perform such maintenance maneuvers on a crane, a maintenance technician trained, for example, by the crane The cockpit should drive some maneuvers of the crane at the request of ma...
