Context 1
... basis of the chassis loader is a rigid frame, which is a welded construction of sheet steel (Fig 1). The most loaded frame elements have a box-shaped cross section. ...
Context 2
... the frame mounted the components and assemblies of the loader: engine, transmission, boom, cab, running gear, etc. In addition, the frame can serve as tanks for the placement of fuel and hydraulic fluid of the loader (Fig 1, b). In this case, the tanks are welded to the frame sheets. ...

The article analyzes the power train components of skid steer loaders. The choice of the scheme and the design of the transmission units of the loader with a traction electric drive is substantiated. The results of calculating the traction characteristic of the straight-line movement of the loader taking into account different values of the coefficient of resistance to movement are presented.

The article analyzes the layout of the main components and units of a skid steer loader. The effect of placing the heaviest components on the tipping load is estimated. The necessity of increasing the duration of the loader without refueling is substantiated. An option is proposed to improve the layout of the machine to increase its operational performance. A test arrangement made using a 3D-modeling system is given.
