TECHNOLOGICAL EFFICIENCY BY CHANGING THE CRANE EQUIPMENT

Abstract

The paperwork includes some considerations regarding the way of establishing the constructive and functional main parameters needed to adapt a crane equipment on a tire excavator. Using a crane equipment on tire excavator is an advantage both for the economy of a service rendering company and for meeting many requirements from various customers. The work equipment on multipurpose excavator is obtained by replacing the work equipment on dragline or grab crane by single hook. Adapting the crane equipment, in case the excavator is provided with dragline equipment, is only the suitable choice of single hook. Specific for such equipment are load lifting – lowering, boom slewing together with excavator platform, boom inclining and travelling function of base machine which, according to load, amplifies the equipment working area. By adapting a crane equipment to tire excavator, a new equipment is got, which, in my opinion, can be part of tire cranes family. Changing the work equipment – hydraulic excavator bucket with crane equipment – shows some advantages like: high maneuverability and mobility, access in narrow spaces, occasional use of crane equipment, equipment cost price is much lower than for a tire crane, only specialized for loads lifting, slewing and travelling.
