Industrial vehicle stability verification
Part 16. Walker vehicles
1 Scope
This part of GB/T 26949 specifies the test method for verifying the stability of walking vehicles.
This section applies to.
---Plug-in, pallet and platform stacking vehicles with a weight of not more than 1000kg or with a battery as the lifting force;
--- Manual lifting with a lifting height of not more than 1000mm and rated lifting capacity of not more than 1000kg or shearing with battery as lifting force
Fork pallet handling vehicle;
--- Platform vehicles.
This section also applies to vehicles equipped with load handling attachments under the same operating conditions.
This section does not apply to vehicles with retractable devices such as retractable gantry or retractable forks.

3 Terms and definitions
The terms and definitions defined by ISO 5053 and ISO 22915-1 apply to this document.
4 test conditions
4.1 General
See ISO 22915-1.
4.2 Position of the vehicle on the inclined platform
If the vehicle is equipped with casters and casters, the casters and casters should be installed during the test and placed in the direction of minimum stability.
(See Table 1, Table 2 and Table 3).
4.2.1 Load bridge and steering axle
Figure 1 defines the load bridge and steering axle of the vehicle.
Stacker vehicle scissor lift vehicle platform vehicle
Description.
AA---the longitudinal center plane of the vehicle;
BB---steering bridge;
CC---load bridge.
Figure 1 Load bridge and steering bridge
4.2.2 Longitudinal stability test conducted in Test 1, Test 2, Test 4 and Test 7 to Test 10
The vehicle should be placed on a tilting platform whose steering axle BB and load bridge CC should be parallel to the tilt axis XY of the tilting platform.
4.2.3 Lateral stability test conducted in Test 3, Test 5, Test 6 and Test 7 to Test 10
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 M points are defined as follows.
a) For vehicles with single or multiple rigid support casters, the M point is the intersection of the caster shaft centerline and the caster wheel width center plane
Vertical projection on the inclined platform, while the center line of the rigid support caster shaft is parallel or located at the tilt axis XY of the inclined platform
(any position) the position of minimum stability.
b) For vehicles with non-hinged double-wheel steering, the M point is the intersection of the steering axle axis centerline and the full width center plane of the two steering wheels.
Vertical projection on the inclined platform, while the centerline of the steering axle is parallel or at the yaw axis XY of the inclined platform (optional
Position) The position of minimum stability.
c) For vehicles with stabilizers, the M point is the vertical projection of the symmetry point of the stabilizer contact surface on the inclined platform.
The N point is the center point of the contact surface of the load wheel closest to the tilt axis XY on the inclined platform.
5 Stability verification
5.1 Dynamic test---platform vehicle
This dynamic test is only available for platform vehicles.
Pushing the empty vehicle to move at a steady speed of (1 ± 0.1) m/s until the single wheel or two wheels touch the vertical height at the same time
20mm obstacle block. The force pushing the vehicle should...
