Structural Stability Test 4.1 Test condition：Weight è100kg Speed è8~10km/h 4.2 The elevation angle is adjusted from the lowest to the highest position. When the movement direction is within a range of ±10°, and within a range of 5° in other directions, the machine must not overturn. 5. Static test 5.1 Test condition: H Class è400kg S Class è600kg 5.2 Test position: Execute load test individually from flat, middle and highest positions for up to one minute. 5.3 Measurement method: Fix the position of running transmission center. Put on a force at the place where behind running area around 66%, force area is 300mm×300mm. If the height of equipment is adjustable, force point must be in the flat, medium-high and highest position as the measurement position. 5.4 Standard of Judgement: The product complies with the instructions and can work normally without any damages. 6.
