PERFORMERS

A shovel is an important household tool, without which it is difficult to do in the garden, when planting trees, on construction site, in the implementation of loading and unloading operations or in the arrangement of territories. Shovels are different, they can be used for digging holes and beds or other digging work, for cleaning work - removing snow and debris, for loading work - loading and unloading bulk materials into a car, wheelbarrow or any other container, shifting bulk materials from place to place . The quality of a shovel is determined not only by the quality of the blade, depending on the type of shovel, but also by the handle. The handle for a shovel should be comfortable, smooth and light.

All shovels are divided into types - gardening, construction and handling. For gardeners, there are three types of shovels: LOP - garden digging shovel, LOV - garden digging shovel, LOW - universal garden shovel. Construction shovels can be pointed, rectangular, pick-up, faceted and mortar. Loading and unloading shovels - sand, snow, grain and coal, metallurgical, rock and mining. For each type of shovels, there are certain cuttings, which a specialist can help you choose. Shovel handles may differ in length and diameter, material quality, pointed and non-pointed, by the type of handles.

wooden cuttings for shovels are considered preferable, they are made of hardwood, they must be smooth, without knots, chips and cracks. In production, cuttings for shovels are made in accordance with established standards. The standard determines the diameter of the handle, the length of the handle, the shape of the handle, the material from which the handle is made, and the grade. Grading sets the limits for permissible wood defects that do not affect the strength of the cutting. Wooden handles for shovels premium should not have any wood defects, knots, wormholes, rot, cracks and chips, most often birch wood is used for their production. The standard diameter of the handle for a shovel is 40 mm, the length can vary from 900-1400 mm.

The grade of cuttings for shovels is determined by GOST 19596-87 “Shovels. Specifications". Shanks for shovels of the highest grade must be free of knots. Shanks for shovels of the first grade - the presence of knots and tobacco knots, not exceeding 3 mm in size, is allowed. Shanks for shovels of the second grade - the presence of knots with a size not exceeding 7 mm and tobacco knots not exceeding a size of 4 mm is allowed. The handle must be qualitatively fixed to the blade of the shovel, which ensures the convenience and safety of working with such a tool. The handle can be fastened to the shovel blade by means of rivets, tightening rings or screws. The quality of fastening the handle to the blade of a shovel is determined by GOST 10299-80 and GOST 1144-80.
