Industrial vehicle stability verification - Part 4. Tray
Stacking trucks, double stackers and operator positions to rise
The height of not more than 1200mm pick the car
1 Scope
This part of GB/T 26949 specifies the test method for the verification of the following industrial vehicle stability.
Pallet stacker
--- double stacker;
--- Operator position lifting height (platform floor height from the ground) is not greater than 1200mm picking car.
This part applies to the same type of industry with tilted or non-tiltable gantry or fork, rated weight not more than 5000kg
vehicle.
This part also applies to the same type of industrial vehicle fitted with load handling under the same operating conditions, and with additional load lift
Set the operator to raise the height of the pick up the height of not more than 1200mm.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, the only dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
ISO 5053 Powered engine technology (Poweredindustrialtrucks-Terminology)
ISO 22915-1 Industrial vehicle stability verification - Part 1. General (Industrialtrucks-Verificationofstabili-
Ty-Part 1. General)
3 terms and definitions
The terms and definitions defined in ISO 5053 and ISO 22915-1 apply to this document.
4 test conditions
4.1 General
See ISO 22915-1.
4.2 The position of the vehicle on the inclined platform
4.2.1 Load bridge and drive/steering bridge
Figure 1 defines the vehicle's load bridge and drive/steering bridge.
Description.
AA --- vehicle longitudinal center plane;
BB --- drive/steering bridge;
CC --- load bridge.
Figure 1 Load bridge and drive/steering bridge
4.2.2 Test 1, Test 2, Test 6, Test 7 and Test 8
The vehicle should be placed on an inclined platform with its drive/steering axle BB and load bridge CC parallel to the inclined axis of the inclined platform
XY, see Table 1.
4.2.3 Test 3, Test 4, Test 5 and Test 9
The vehicle should be placed on an inclined platform so that the MN line is parallel to the tilt axis XY of the inclined platform, see Table 1.
M points are defined as follows.
A) For vehicles with a single non-articulated drive/steering wheel. M is the center of the drive/steering wheel shaft and the center of the drive wheel
The vertical projection of the intersection of the surface on the inclined platform.
B) For vehicles where the drive/steering bridge is mounted on the hinge frame and the hinge points are located in the longitudinal center plane of the vehicle. M is the hinge
The vertical projection of the intersection of the transverse axis and the vehicle longitudinal center plane AA on the inclined platform.
C) For vehicles with rigid support for single or double casters. point M is the center wheel of the caster wheel and the center of the single wheel
Or the intersection of the center plane of the two-wheeled casters in the oblique plane, while the rigid support of the caster wheel
Heart line parallel to XY.
D) For vehicles with a non-rigid support casters and a single rigid support drive/steering wheel. point M is the drive wheel axle
The intersection between the center line and the drive wheel width center plane is perpendicular to the tilting platform, and the drive wheel is parallel to the XY.
E) For vehicles with non-articulated dual drive/steering wheels. point M is the drive axle center line BB and the drive wheel near XY
The intersection of the center of the wheel width is perpendicular to the tilting platform, and the drive wheel is parallel to the XY.
F) For vehicles with non-articulated, rigid support casters for the chassis, point M is.
1) The intersection of the center line of the caster shaft and the center of the caster wheel center is perpendicular to the inclined platform, while the rigid caster wheel
The heart line should be parallel and away from XY;
2) Caster wheel center of the intersection of the vertical projection on the inclined platform, while the rigid caster wheel centerline should be parallel and far
From XY.
G) For vehicles with a single non-articulated drive/steering wheel and non-rigid support casters on the central plane AA. M points
Is the vertical projection of the intersection of the centerline of the drive wheel shaft and the center of the drive wheel width on the inclined platform, while driving the wheel axle
The centerline is perpendicular to the tilt axis XY, and the center line of the nearest caster wheel from XY should be parallel and away from XY.
As shown in Table 1, point N is defined as the center of the contact surface of the load wheel closest to the tilt axis XY on the tilting platform.
4.3 Load reference point position
4.3.1 General requirements
In the test 1, when the fork from the low rise, the load reference point E horizontal position should not change, as shown in Figure 2.
So that the mast is vertical, the specified test load up to about 300mm above the tilt platform. The vertical section of the fork is perpendicular to the front surface
If the fork or fork is fixed in relation to the centroid of the test load, point E may be set on the fork or fork, as shown in Figure 2 (a).
E should be used as reference point for tilting platform F point. When the gantry rises, a new F1 point may be generated on the tilting platform, such as
As shown in Figure 2 b). The new F1 point can be returned to the initial position F point, as shown in Figure 2 c).
For vehicles with tiltable gantry, the position of the F1 point should be adjusted by adjusting the inclination of the gantry within the allowable range of its design value.
As shown.
For vehicles with non-tiltable gantry, the F1 point can be returned by adjusting the fork or fork in the range of its design value
Initial position F point.
A) b)
C)
Figure 2 Location of the load reference point
4.4 Simulating the lifting height of the test run
When the simulation test (test 2, test 4, test 5 and test 8) is carried out, the upper surface of the fork should be measured at the beginning of the fork
In the tilt platform 300mm or as close as possible to the outrigger legs, whichever is greater.
4.5 Position of the upper load of the double stacker
For vehicles with two loads, one of which is loaded on the support leg, the other is loaded on the fork, the upper load is placed
The fork on the surface of the fork should be.
--- the standard load center distance of 500mm, the distance from the support of the bearing surface 1100mm;
--- standard load center distance of 600mm, the distance from the support of the bearing surface of 1300mm.
5 stability verification
The stability of the vehicle shall be verified in accordance with Table 1.
