Embodiment Construction

[0024] Next, preferred embodiments of the present invention will be described with reference to the drawings.

[0025] figure 1 A holding device 10 according to the first embodiment of the present invention and a construction machine 100 including the holding device 10 are shown. The holding device 10 is installed on the construction machine 100 and holds a conveyed object as a holding object. This holding device is particularly suitable for the case where the loads are open upwards. The construction machine 100 includes a work attachment 130 for performing work operations. figure 1 The construction machine 100 illustrated in is a hydraulic excavator.

[0026] The construction machine 100 includes a lower traveling body 110 , an upper slewing body 120 and the working attachment 130 .

[0027] The lower walking body 110 can perform walking action, for example, it includes a pair of caterpillar belts. The upper slewing body 120 is rotatably installed on the lower walking bo...

Abstract

This holding device is provided with holding device bodies (30, 40), first and second arms (60A, 60B), an opening / closing mechanism (50), a drive device (70), and first and second holding parts (90A, 90B). The opening / closing mechanism (50) connects the first and second arms and the holding device main body such that the first and second arms move in the opening / closing direction while maintaining the holding posture. The first and second holding portions are rotatably connected to the arm lower portion (62). The first and second holding portions have inner contact surfaces (93a, 94a) facing each other in the opening / closing direction and outer contact surfaces (95a, 96a) on the opposite sides thereof. Therefore, the object to be held can be flexibly held by sufficient holding force according to the shape of the object to be held from any one of the outer side and the inner side.
