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 force are measured. 2. Maximum operating force of the levers, pedals, and steering wheel are measured. 3. Measurement of each of the operating levers is made at the center of the grip. Measurement of each of the pedals is made at 150 mm (6 in) from the pedal support. Preparation: 1. In the front position, empty the bucket in advance. 2. Keep the hydraulic oil temperature at 50 ± 5 ° C (122 ± 41 ° F). Measurement 1. Make measurement for each of the operating levers, pedals, and steering wheel. 2.
Select the pedal, switches, and forward-reverse lever as follows. Travel Position 0.4 to 0.5 m (1’4” to 1’8”) M4GB-04-001 that there are no human beings or obstacles in the steering range. 3. Apply a spring balance scale (tension type) to each of the lift arm, bucket, and froward-reverse lever, and measure their maximum operating ef- forts by operating them to the stroke end. 4. In the case of the pedals, apply a spring balance scale (compression type) or a load cell to them, and measure their operating efforts when they are stepped slightly. 5. For the steering wheel, apply a spring balance scale (tension type) to the knob, and measure the maximum operating effort when it is moved. 6.
Make measurement three times, and determine the measurement value by obtaining their mean values. Evaluation: Refer to the Performance Standard Table in Group T4-2.
