Abstract

PURPOSE: To satisfy ISO, 3449, and to lighten a cab head guard for a construction equipment for reducing a burden on a cab by installing a projecting arcuate steel plate to an upper section through a bracket mounted onto a cab head while interposing a rubber board between the bracket and the edge section of the steel plate. CONSTITUTION: A bracket 2 is fixed onto a cab head 1a, and a steel plate 4, in which an upper section is formed in a projecting arcuate shape, is set up by bolts. Consequently, strength is made higher than a plate. The edge sections of the steel plate 4 are fastened through rubber boards 3 at that time. Accordingly, a cab head guard for a construction equipment resists deformation, and an impact is absorbed, thus reducing damage to a cab. A rubber is used for mounting, thus further absorbing the impact.

Since the head guard is formed in an upward convex arc shape, it is resistant to deformation, and because of the arc shape, the clearance generated between the head guard and the cab head is larger than that of a flat plate. Even when the is deformed, damage to the cab can be reduced. Moreover, shock can be further absorbed by using rubber for mounting.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An explanation will be given with reference to FIGS. 1 and 2. In FIG. 1, reference numeral 1 is a cab body. Bracket 2 on cab head 1a
Are fixed and the steel plate 4 is attached with bolts 5. The steel plate 4 is formed in an upward convex arcuate shape, and its end edge is fixed via the rubber plate 3. Since the steel plate is formed in an arc shape, the strength can be increased as compared with the conventional flat plate steel plate. By the way, the conventional flat steel plate has a weight of about 90 kg, but since it has an arc shape, it is possible to have a sufficient equivalent strength even if it is reduced by about 50 kg, that is, about 45%. Further, if the beading process for attaching the strip plate to the arc-shaped steel plate is performed, it is possible to further increase the strength in combination with the upward convex arc shape.

[Effect] ISO. The test specified in 3449 is a method in which the energy (11,600 J) generated when the standard test weight (227 kg) is dropped from a height of 5.2 m is absorbed by the deformation of the head guard. Since the head guard is formed in a convex arc shape upward, it is strong against deformation,
Also, because of the arc shape, the clearance generated between the head and the cab head is larger than that in the case of a flat plate.
The damage to the cab can be reduced even when the door is deformed. Moreover, shock can be further absorbed by using rubber for mounting.
