The structural types of the chassis are divided according to the loading and unloading methods during storage and transportation in accordance with Table 1. Table 1 Chassis type
Use chassis for lifting or roller loading and unloading, handling
Directly lift the contents themselves, only use
Chassis for roller loading and unloading, handling
As a universal chassis, it is suitable for all kinds of objects
Mainly suitable for objects that can be directly lifted
The basic structure of type A chassis is shown in Figure 1. Type B chassis has the same structure as type A chassis except that auxiliary slides are not installed and the ends of the slides need to be made into chamfers.

Auxiliary slide
Auxiliary slide
The dimensions of slide shall be determined according to the weight of the contents, the center interval of the sleepers and the placement of the contents on the chassis. 4.1.1.1 When using a type A chassis, the cross-sectional dimensions of the slide shall be determined according to the following two situations. a: As shown in Figure 2, when the two outermost sleepers that fix the contents to the chassis are both beyond the lifting point, the cross-sectional dimensions of each slide shall be selected according to Table 2.

Center spacing 1 between two sleepers at the lifting point
As shown in Figure 3, when the outermost fixing point of the contents and the chassis is on the inner side of the two lifting points, the cross-sectional dimensions of the slide shall be selected according to Table 2. However, in this case, the "center spacing 1 between two sleepers at the lifting point" in Table 2 shall be the "distance 1 between the lifting point and the outermost fixing point of the contents". This value shall generally not be greater than 60cm. Lifting rope
4.1.1.2 When using a B-type chassis, the cross-sectional dimensions of the slide shall be selected according to Table 2. However, in this case, the "center spacing 1 between two sleepers at the lifting point" in Table 2 shall be the "maximum center spacing between any two adjacent sleepers", and the width of the slide selected from Table 2 shall be one-half of the sum of the widths of all slides used.
4.1.1.3 The cross-sectional dimensions of the slides should preferably be equal to or greater than the thickness. 4.1.2 Number of slides
The center distance between two adjacent slides is generally not more than 120cm. When a forklift is used to transport the slides horizontally, the center distance between the slides should not be more than 100cm (when the weight of the contents is less than 1500kg, it should not be more than 80cm). If it exceeds the regulations, slides with the same cross-sectional dimensions or the same thickness should be added in the middle.
4.1.3 Butt joint of slides
As a whole slide, try to use a whole slide. If the length is not enough, you can use the method shown in Figure 4 for butt joint. The butt joint position cannot be near the center of the length or the lifting point. The butt joint positions of each slide should be staggered. When the width of the slide is less than or equal to 9cm, use M10 bolts to connect, and when it exceeds 9cm, use M12 bolts to connect.

4.1.4 Structure of both ends of slide
For B-type chassis, the two ends of the slide should be made into a chamfer angle of 35~45 at about half the height from the bottom surface. As shown in Figure 5. 45
4.2 Auxiliary slide
A-type chassis needs to be installed with auxiliary slides to adjust the lifting position or the position of the hole of the car. 221
GB 1081989
4.2.1 The size of the auxiliary slide. The width of the auxiliary slide should be more than 80% of the width of the slide. Its thickness is selected according to Table 3. The auxiliary slide can be butt-jointed along the length. When rollers are required for loading and unloading, the two ends of the auxiliary slide should be made into a guide angle of 35 Table 3 Thickness of auxiliary slide

4.2.2.1 When the contents are unbalanced objects, the installation position of the auxiliary slide should ensure that the chassis is in a balanced state during the lifting operation. 4.2.2.2 When two sleepers are used and the contents are non-unbalanced objects, the two ends of the auxiliary slide are generally about 20cm away from the two ends of the slide. 4.2.2.3 When three sleepers are used and the contents are not eccentrically heavy, the installation position of the auxiliary slide is shown in Figure 6. Figure 6
4.2.2.4 When more than four sleepers are used and the contents are not eccentrically heavy, the installation position of the auxiliary slide is shown in Figures 7 and 8.
GB10819-89
4.2.2.5 For chassis that require a sled for loading and unloading, the positions of the two fork holes should be at an equal distance from the center of gravity of the contents, and the width of the fork holes and the distance between the two fork holes shall be in accordance with the provisions of Figure 9 and Table 4.

4.2.3 The auxiliary slide is nailed to the bottom of the slide with steel nails, and the steel nails are staggered in two rows. The spacing between the steel nails in the same row is not more than 30cm. 4.3 End Wood
The end wood is a component that connects the slide rails horizontally and is installed at both ends of the slide rails. 4.3.1 Dimensions of End Wood
When the contents are not placed on the end wood, the dimensions of the end wood and the dimensions of the mounting bolts shall be in accordance with the provisions of Table 5. When the contents are installed on the end wood, the dimensions of the end wood shall be the same as those of the sleepers. Table 5 Dimensions of end wood and connecting bolts

4.3.2 Installation method of end wood
When the width of the end wood is less than 15 cm, each connecting part is installed on the sliding wood with one bolt, while when the width of the end wood is greater than 15 cm, two bolts are used for connection.
4.4 Sleepers
4.4.1 Dimensions of sleepers for Type A chassis
4.4.1.1 When the sleepers are subjected to uniform load, the cross-sectional dimensions and quantity of the sleepers are determined by Table 6. When more than five sleepers are used, the dimensions are the same as when four sleepers are used. However, even if more than five sleepers are used, if the lifting position is as shown in Figure 10, the dimensions of the sleepers are still the same as when three sleepers are used.

4.4.1.2 When the sleepers are subjected to the concentrated load as shown in Figure 11, the cross-sectional dimensions of the sleepers are determined by the following method. -2
W-weight of contents
When 1,12, multiply the allowable bending load value in Table 6 by the value of formula (1) as the allowable bending load value in this case. 12
4 (1 -1,+12) lt
When! ,=12, multiply the allowable bending load value in Table 6 by the value of formula (2) as the allowable bending load value in this case. However, when the values ​​of formula (1) and formula (2) are greater than 2.5, the calculation shall still be based on 2.5. 1
3 When the contents are cylindrical as shown in Figure 12, assume that the center point of the contact point α, 6 between the contents and the sleeper and the stopper is c, then 4.4.1.3
GB10819-89
Use point c to write the distance between the inner side of the outer slide as! , and then calculate the allowable load value according to Table 6 and formula (1) or formula (2). Figure 12
4.4.2 Sleeper size of B-type chassis
The sleeper size of B-type chassis is determined by the same method as that of A-type, but when more than three slides are used, the value in Table 6 can be doubled.
