O. The performance requirements specified in 3449 must be met. In order to satisfy this, a thick and heavy flat steel plate was used as described above. 3449
The purpose is to reduce the weight of the cab and reduce the burden on the cab.

使用することでさらに衝撃を吸収することができる。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.

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.

撃を吸収することができる。[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.
