Abstract
The claw for round bales is an attachment to the base machine of a front loader. This is used in agriculture for handling of big sized straw bales. Arms opening respectively, closing, are performed with different speeds to allow claws removal from bales stack without damaging the nearby bales. The strong construction ensures handling of big sized bales. The needed force during transport is provided by two hydraulic cylinders and hydraulic safety valve. For making the transport systems used in agriculture, it is useful to make computer aided simulations, to obtain some virtual models for such equipment. This paperwork presents how the claw for round bales handling can be designed, starting from needed parameters (bale size, bale weight, lifting capacity, etc.) and farmer’s requirements. We went through the stages of computer aided engineering taking into account various requirements of the farmers. The claw for bales handling is attached to a front loader or a tractor based upon the equipment fleet the farmers own. The parametric modeling of the claw type attachment for round bales was done by using NX 7.5 specialized software. This software uses powerful tools for modeling, allowing the use of the most efficient techniques for advanced modeling – from explicit modeling of solids and surfaces to parametric and direct modelling.
