Added the requirements for whether the vehicle needs to be tested for static cutting. 4.1.2 was cancelled and 4.1.2 was replaced by 4.1.2. The test date was added in 4.2.1 and 4.3.1. —-4.2.3 The time for the expansion channel to bear the test load shall not be less than 10min shall be changed to not less than 1min. 4.3.3 The increase in the machine, its angle and control should have a return of 10-15mn, and 4.3.4 shall be replaced by 1U-point in the original standard. The center position of the test object shall be adjusted to the fixed point according to the conditions of 15(5353) and the other S points. 4.4 Replace the original standard. 4.2.3 and 43.4, the water deformation after the net potential test 1m\ is changed to 23m. The standard replaces GB/5143-1585.6 standard from the month of birth. The standard is proposed by the China Machinery Industry Federation. The public standard is produced by Beijing Transportation Machinery Research Institute. Standard drafting unit: Beijing Hoisting Machinery Research Institute. The name of the standard should be shared by: GB/T51432001 ISO (International Organization for Standardization) is a global organization of international standardization bodies (ISO member bodies). The drafting of various international standards is mainly completed through the technical committees of TS. Each local body with an interest in a subject that has been confirmed by a certain committee has the right to request participation in the technical requirements of the committee. Some foreign and non-foreign international organizations can participate in this work, and work closely with the International Electrotechnical Commission in all electrotechnical fields. The technical committee will circulate the adopted international standard draft to the member bodies for voting. As an international standard, the committee requires at least % of the service group fee, and the technical committee of the International Standard 1505055 is the technical committee of 1S0TC110 (Ministry of Industry and Transportation) of the Ministry of Industry and Transportation of China:2 Powered Industrial Vehicle Safety Lifting System. This second edition of the standard replaces the first edition of 190055 published in 190.

3 Technical Requirements
3.1.1 When the load is replaced by the replacement position of the vehicle, the control of the vehicle manufacturing is selected When the guardrail is fixed on the door, the above requirements also apply to the guardrail fixed on the door frame. The vertical projection of the handle, foot and plate of each handle (respectively in the middle position) without cutting the guardrail in the direction of the door frame in the plane (see Figure 1) is 15 cm, regardless of whether the parking brake is in the released state.

If the distance between the front end of the guard and the front end of the vehicle as the first guard is less than 1m in the horizontal mountain (see Figure 1), it is considered that the protection is sufficient. 3.1.2 When the dumper is in operation, the guard shall not be directly connected to the top frame of the vehicle to expose the personnel to other risks: 3.2 3.2.1 The structure of the roof guard should be well planned. 3.2.2 The length of the roof guard should not exceed 15 cm. 3.2.3 For high-rise vehicles: The vertical distance from the lowest point of the rear seat to the lower surface of the roof guard should not exceed 1 km. If the seat is adjusted vertically, the seat should be adjusted to the middle position. 3.2.4 For high-rise vehicles: The vertical distance from the lowest point of the rear seat to the lower surface of the roof guard should not exceed 1 km. For high-rise vehicles: The vertical distance from the lowest point of the rear seat to the lower surface of the roof guard should not exceed 1 km. For high-rise vehicles: The vertical distance from the lowest point of the rear seat to the lower surface of the roof guard should not exceed 1380 cm. 3.2.5 When the user makes a request, the manufacturer can reduce the normal height of the roof guard and the distance between the driver's head and the lower side of the top of the roof guard so that the vehicle equipped with the roof guard can operate within the clearance limit of the vehicle's total height. 4 Tests
4.1.1 The guardrail should be installed on the vehicle for which it is designed and for which the peak load and load rating are specified and shall be tested or certified as above. In addition, if the guardrail is tested and found to be installed in the same manner as on the new vehicle, and if there are lift limit devices installed on the guardrail or other parts of the vehicle, a small-scale test can be carried out: For a wave pressure lift, if the guardrail shows sufficient variation, it can be used as the lift limit. 4.1.2 For installation methods or using the same guard frame and extension, the static load test shall be carried out according to 4.2 first, and then the dynamic load test shall be carried out according to 1.3. 4.2 Static load test 4.2.1 The test date shall be sufficient to ensure that the test is carried out. 4.2.2 The test load shall be determined by the relationship between the size of the top guard frame load and the vehicle load. Table 1 details the test load and the load requirements. 2 0: Q5b G0

The test object shall be subjected to self-falling from an external position, which may be parallel to the base of the frame. The test object shall be dropped 3 times at a distance of 10m from the top of the frame. One of the drop points shall be faster than the center of the test object (according to 1S0=353, the center of the test object shall be adjusted to the position of the driver or the center of the driver's standing position). The center of the test object shall be randomly distributed within a radius of 6 meters. The center of the test object shall be located directly above the center of the driver's standing position (adjustment rate position). When the test object is subjected to the force determined by the test object, the initial physical properties of the object shall be changed as expected. 4.4 (Figure 3)
After the two tests, the guardrail shall not crack, the height of the component shall not be greater than 20Hm, or its permanent deformation in the direction of the required force shall not exceed 20Hm. During the dynamic test, the materials installed between the guardrails specified in 3.2, such as steel mesh, tempered glass, transparent glass, etc., shall not be in a hurry.
