OPERATIONAL PERFORMANCE TEST / Wheel Loader Test CONTROL LEVER OPERATING FORCE Summary: 1. Operating conditions of the levers, pedals and steering wheel are confirmed, and their operating forces are measured. 2. Maximum operating force of the levers, pedals, and steering wheel are measured. 3. Measurement of each operating lever is per- formed at the center of the grip. Measurement of each pedal is performed at 150 mm (6 in) from the pedal support. Preparation: 1. In the front attachment position, empty the bucket in advance. 2. Keep hydraulic oil temperature at 50 ± 5 ° C (122 ± 9 ° F). Measurement: 1. Measurement for each levers, pedals and steer- ing wheel. 2.
Select the pedal, switches and FNR lever as fol- lows. Travel Position 0.4 to 0.5 m (1’ 4” to 1’ 8”) M4GB-04-001 that there are no person or obstacles in the steering range. 3. Attach a spring balance scale (tension type) to the lift arm, bucket and FNR lever. Measure the maximum operating force while operating them to the stroke end. 4. For the pedals, attach a spring balance scale (compression type) or a load cell at the meas- urement position and measure the operating force while slightly depress the pedal. 5. For the steering wheel, attach a spring balance scale (tension type) to the knob, and measure the maximum operating force while operating. 6.
Repeat measurement three times and calculate the average values. Evaluation: Refer to Performance Standard Table in Group T4-2.
