FIELD: earth-moving equipment; transport equipment.

SUBSTANCE: working equipment of a front-end loader that can be used when performing loading and unloading, earth-moving, transport, and snow removal operations. The front loader bucket is a structure consisting of a bottom, a rear wall, and side walls, having a cutting perimeter formed by a horizontal and two vertical cutting profiles, as well as stiffening boxes and brackets with eyes for attaching the bucket to the boom and the rods. The rear and the side walls are made in the form of a solid structure made of a polymer composite material, which, using a riveted connection, is attached to the inner part of the welded structure of the bottom with a horizontal cutting profile fixed in its front part by means of a bolted connection and a welded metal frame formed by two vertically parallel to each other and stiffening boxes that follow the profile of the rear wall of the bucket. On the outside of the stiffening boxes there are brackets with eyes for attaching the bucket to the boom and the rods. The stiffening boxes are connected in the front part by a U-shaped bent metal element forming a lip and two vertical cutting profiles of the bucket, and in the rear part - by a horizontal reinforcing metal strip repeating the profile of the side and the rear walls that connects the stiffening boxes to each other and to the vertical cutting profiles.

EFFECT: improved operational and process parameters of the product, reduced weight, and increased structural durability.
