Construction Equipment

MoreVision has a particular expertise in the structural design of construction equipment. We have devised new methods of assessment for our clients and invested in software to speed up the assessment procedure. This software is available for use and/or modification as required by new contracts.  

 Kinematics Analysis of an Excavator Arm

 Assessment of a Loader Arm

MoreVision developed an ANSYS script to generate a simple beam model of a loader and chassis which could be positioned in any geometric configuration (loading position, raised position etc.). The model was used to determine free body forces acting on each component in the machine (Chassis, arm, links, rods and buckets). The free body forces could be extracted from the beam model and applied to a detailed solid finite element model of each component (the picture opposite shows the arm component). The solid models were used to perform a detailed static strength and fatigue strength checks. A non-linear plastic analysis of this arm was also performed for an overload case to determine the permanent and magnitude of residual stresses.

 Claas Teleporters

Claas had acquired a business which manufactured telehandling vehicles. Traditionally telehandling vehicles have been designed without any particular structural design methodology. MoreVision were commissioned by Claas to devise a design code of practice for the vehicle, this included the telescopic arm and the vehicle chassis. A full static and fatigue assessment of the vehicle chassis was then undertaken and a summary of design change recommendations was delivered to the client.
