Abstract: At present, excavation machines are widely used in the mining industries, forestry work and construction industries. These excavation machines are of heavy size and used for heavy duty construction work, but they are costlier and complex in nature. These heavy duty machines are not required to carry out the digging operation efficiently particularly for light duty construction work and are not so economical. So, there is a scope to develop a backhoe attachment for light duty construction work and it can be applicable for autonomous excavation, but for this purpose, it is necessary to determine the kinematic working range of backhoe attachment using solid modelling. This paper focuses on the evaluation of kinematic working range of the proposed backhoe attachment and compared it with the working range of the available models of mini hydraulic backhoe excavators. The result shows the overall improvement in the kinematic working range of the proposed backhoe excavator attachment.

Keywords: hydraulic backhoe excavators; excavation machines; digging; backhoe attachments; light duty construction; autonomous excavation; solid modelling; kinematic working range; kinematics; heavy vehicles.
