Problems solved by technology

[0006] The shape of the crane may change due to the assembly or disassembly of parts, thereby changing the monitoring area. However, in the above-mentioned conventional technology, the monitoring area is fixed in a preset range, so it cannot cope with the change of the monitoring area. Therefore, it is difficult to make an appropriate judgment in the case of a change in form during disassembly or assembly

Embodiment Construction

[0032] [Outline structure of crane]

[0033] figure 1 is a side view of the crane 1 . The crane 1 is a so-called mobile crawler crane. Regarding the crane 1 , the front, rear, left, and right directions seen by the occupants of the upper revolving structure 3 will be described as the front, rear, left, and right directions of the crane 1 . In principle, the front, rear, left, and right of the undercarriage 2 will be described assuming that the front-rear direction of the undercarriage 2 coincides with the front-rear direction of the upper-part revolving body 3 (reference posture).

[0034] Such as figure 1 As shown, the crane 1 is configured to include a crawler-type lower traveling body 2 capable of self-propelling, an upper rotating body 3 rotatably mounted on the lower traveling body 2 , and a movable body mounted on the front side of the upper rotating body 3 in a pitchable manner. arm 4.

[0035] The undercarriage 2 includes a main body 21 and crawler belts 22 provid...

Abstract

The purpose of the present invention is to monitor the surroundings by using an appropriate monitoring area in accordance with changes in a crane. The present invention provides the crane (1) capable of being assembled and disassembled, which is configured to be capable of changing the monitoring range of surrounding monitoring according to the assembling state of the crane (1). For example, when the counterweight (5) is not mounted, the reference monitoring range (W1) is changed to the narrowed monitoring range (W2). If the monitoring range is changed according to the change of the assembly state, surrounding monitoring can be performed in an appropriate range, thereby maintaining operability and realizing good surrounding monitoring.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2020-057228 filed on March 27, 2020. The entire content of this Japanese application is incorporated in this specification by reference. technical field [0002] The present invention relates to a crane and a monitoring device of the crane for surrounding monitoring. Background technique [0003] Conventional cranes photograph the surroundings of the hanging load and display the bird's-eye view image based on the shooting on the monitor in the crane's cab, thereby detecting workers around the hanging load and displaying their helmet images in the bird's-eye view image. [0004] Furthermore, if a worker is detected in a dangerous area around the hanging load, a helmet image is displayed in black to warn the driver (for example, refer to Patent Document 1). [0005] Patent Document 1: Japanese Patent Laid-Open No. 2010-241548 [0006] The shape of the crane may change due to the assembly or disa...
