Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments. The technical solutions in the embodiments of the present invention are clearly and completely described, and the described embodiments are only some embodiments of the present invention, not all embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model discloses an embodiment of large-scale bull-dozer is with high strength planet wheel carrier, large-scale bull-dozer is with high strength planet wheel carrier includes integrated casting shaping's bottom suspension fagging 1 and last backup pad 2 in this embodiment, connects through integrated casting shaping's 3 support columns 3 between the two.

Go up backup pad 2 and bottom suspension fagging 1 and all be the ring shape, the diameter of bottom suspension fagging 1 is greater than last backup pad.
