XCMG Spare Parts Base Plate of Spherical Base 155300228

This OEM base plate 155300228 is an original XCMG supporting spare part custom-made for spherical base assemblies, widely fitted on XCMG truck crane and concrete pump outrigger systems. It works as the bottom load-bearing foundation locking spherical core parts into place against outrigger legs on construction sites.

Crafted from high-density cast steel via precision forging, the plate goes through whole-surface quenching treatment to boost surface hardness and compression resistance. Precisely positioned bolt holes are pre-machined per factory drawing to match original spherical base mounting dimension without on-site reaming.

Its concave inner surface fits tightly with spherical base convex face, distributing heavy vertical load evenly when outriggers extend for full machine stabilization. This close fit offsets uneven ground pressure and avoids partial deformation under frequent heavy-duty onsite operation.

Finished with anti-rust spray coating all over outer surface, this component stands up to mud, rain and grit from rough construction environments. It cuts premature abrasion between contact faces and lengthens overall service cycle of the whole spherical support set.

Direct factory genuine stock ensures seamless drop-in replacement for worn original pieces. No modification required during installation to restore outrigger supporting stability for regular lifting and pumping work on site.
