Industrial vehicle stability verification
Part 22. Operator position can be or
Non-lifting three-way stacker forklift
1 Scope
This part of GB/T 26949 specifies a three-way stacker forklift that verifies that the operator's position may or may not rise (eg ISO 5053-1)
Test method for the stability of the definition).
This section applies to vehicles with forks, shuttle forks and/or integral attachments under normal operating conditions.
This section also applies to vehicles in which the load handling device can be moved sideways or rotated and offset from the longitudinal center plane of the vehicle.

3 Terms and definitions
The following terms and definitions defined by ISO 22915-1 apply to this document.
3.1
Normal operating conditions normaloperatingconditions
The working condition of the vehicle running on the ground level, level and hard enough (such as concrete).
3.2
Guided steering guidedsteering
Mechanical (such as rails) or non-mechanical (such as electromagnetic guidance, laser sensors or infrared guidance systems) that are not directly controlled by the operator.
Steering for guiding the steering of the vehicle along a predetermined straight path.
3.3
Restricted steering restrictedsteering
The steering of the vehicle is controlled by the operator, and the angle between the steering angle and the forward and backward running directions is not more than ±10°.
3.4
Unrestricted steering unrestrictedsteering
The steering of the vehicle is controlled by the operator and the steering angle is not limited.
4 test conditions
4.1 General
See ISO 22915-1.
4.2 Location of the vehicle on the inclined platform
4.2.1 Load bridge and steering axle
Figure 1 defines the load bridge and drive/steering axle of the vehicle.
Description.
AA --- longitudinal center plane of the vehicle;
BB --- drive/steering axle;
CC --- load bridge.
Figure 1 Load bridge and drive/steering axle
4.2.2 Test 1, Test 2 and Test 3
The vehicle should be placed on a tilting platform whose drive/steering bridge BB and load bridge CC should be parallel to the tilt axis XY of the tilting platform.
See Table 1.
4.2.3 Test 4
The vehicle should be placed on a tilting platform with its longitudinal center plane AA parallel to the tilting axis XY of the tilting platform, see Table 1.
4.2.4 Test 5, Test 6 and Test 7
The vehicle should be placed on a tilting platform such that the MN line is parallel to the tilt axis XY of the tilting platform.
The definition of point M is as follows.
a) For vehicles with dual drive (steering) wheels, point M is the intersection of the transaxle centerline and the vehicle center plane AA
Vertical projection on the stage;
b) For vehicles with a single drive (steering) wheel, the M point is the drive (steering) wheel axle centerline and the drive wheel width center plane
Vertical projection of the intersection on the inclined platform;
c) For vehicles with casters or wheels with non-rigid support, the M point is the centerline of the drive wheel axle and the wide center plane of the drive wheel
Vertical projection of the intersection on the inclined platform;
d) For vehicles with drive (steering axle hinged on the frame), point M is the intersection of the transverse axis of the articulated steering axle and the hinge point
Vertical projection on a tilting platform;
e) For vehicles with non-hinged drive wheels, the M point is the intersection of the centerline of the drive wheel axle and the center plane of the drive wheel.
Vertical projection on the platform;
f) For vehicles with non-hinged, rigid casters or wheels, the M point is the caster or wheel axle centerline and the caster or wheel width
The vertical intersection of the intersection of the center plane on the inclined platform, and the center line of the caster or wheel axle should be close to the center plane of the vehicle;
g) For a five-wheel suspension vehicle with four solid wheels and one articulated wheel, the M point is a three-wheel articulated frame rotation center shaft and tire
Projection of the intersection of the centerline on the inclined platform;
h) For vehicles with articulated steering in the middle of the frame, point M is the intersection of the centerline of the drive wheel axle and the center plane of the drive wheel.
Tilt the projection on the platform.
The N point is the center point of the contact surface of the front load wheel closest to the tilt axis XY on the inclined platform.
4.3 lifting height
The lift height of the test is the distance measured from the inclined platform to the highest point of the load carrying surface.
5 stability verification
The stability of the vehicle should be verified according to Table 1.
