Industrial vehicle stability verification
Part 13. Cross-country forklifts with gantry
1 Scope
This part of GB/T 26949 specifies that the rated lifting capacity of a gantry with a fork or load carrying is not more than 10,000 kg
Test method for stability of off - road counterbalanced forklift truck.
This section does not apply to vehicles that carry freight containers.
2 normative reference documents
The following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article
Pieces. For undated references, the latest edition (including all modifications) applies to this document.
ISO 5053 Motorized Industrial Vehicle Terminology (Poweredindustrialtrucks-Terminology)

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 axle/steering axle
Figure 1 defines the vehicle's load bridge and drive axle/steering axle.
Description.
AA --- vehicle longitudinal center plane;
BB --- steering bridge (in the 4-wheel drive vehicle can also be the drive axle);
CC --- load bridge (in the 4-wheel steering vehicles can also be steering bridge).
Figure 1 Load bridge and drive axle/steering axle
4.2.2 Stabilizer/axle locking device
If a stabilizer or axle lock is installed, it should only be used for test 1 and test 3.
4.2.3 Test 1 and Test 2
The vehicle should be placed on an inclined platform with the load bridge CC parallel to the tilt axis XY of the inclined platform, see Table 1.
4.2.4 Test 3, Test 4 and Test 5
The vehicle should be placed in a tilted platform on a tilting platform so that the MN line is parallel to the tilt axis XY of the inclined platform.
As shown in Table 1, the steering wheel closest to the tilt axis should be parallel to the tilt axis XY. M points are defined as follows.
a) For vehicles with articulated steering bridges. point M is the intersection of the vehicle longitudinal center plane AA and the steering axle axis at the inclined platform
On the projection (see Table 1);
b) For vehicles with articulated frames. the two parts of the frame to the limit position, M point is the rear frame longitudinal center JJ and after
The intersection of the bridge axis on the inclined platform (see Table 1);
c) For a vehicle with a axle lock device. M is the center of the reclining platform with the rear wheel contact surface closest to the tilt axis XY
Point (see Table 1).
As shown in Table 1, point N is defined as the relationship between the tilting platform surface and the load wheel (or the stabilized leg) that is closest to the tilt axis XY
The center of the contact surface.
4.3 Position of load reference point
When the test 1 is carried out, the horizontal position of the load reference point E should not be changed when the fork is lifted from the lower position, as shown in Fig.
So that the mast is vertical, the specified test load up to about 500mm 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, E can be set on the fork or fork, as shown in Figure 2a). E points
Should be used as a reference for the tilting platform F point. When the gantry rises, a new F1 point may be generated on the tilting platform, as shown in Figure 2b)
As shown. Adjusting the mast inclination within its design allowable range allows the new F1 point to return to the initial position, point F, as shown in Figure 2c).
Figure 2 Position of the load reference point
4.4 Lifting height
When the simulation test (test 2 and test 4) is carried out, the fork is fully tilted and is measured from the fork at the fork, and the upper surface of the fork should be high
In the tilt platform 500mm.
For test 3, the vehicle should be at the maximum lifting height and at the maximum backwards, or tilted 10 °, or 600%
Choose one of the most unfavorable conditions of stability.
4.5 Horizontal test procedure (only for test 3)
For vehicles with optional ope...
