| An electromechanical implement lift system comprising of two lower links, one top link, two lift rods, one connecting rod and power screw mechanism fitted on a frame was developed with position control to replace the commonly used hydraulic system for implement lifting requiring higher power. The prototype was tested as per IS: 12224-1987 for recommended load of 150 kg on test frame and satisfactory results were found. The response time for lifting a load of maximum lifting capacity on test frame i.e. 116 kg and 110 kg for entire lifting range was found to be 71 s and 20.7 s for single start screw and triple start screw, respectively as compared to 44.7 s and 13.3 s for lowering the loads. The position control of the system was also tested and found... |
