In the embodiments, a plurality of parallel and inclined first supports 422 are provided on a first side of the vehicle body 1, and a plurality of parallel and inclined second supports 424 are provided on a second side of the vehicle body 1, so that the plurality of first supports 422 and the plurality of second supports 424 form a support platform above the vehicle body 1, so that both sides of the fork 3 can be directly mounted on the support platform formed by the plurality of first supports 422 and the plurality of second supports 424, so that the support mounting of the fork 3 can be achieved by the plurality of supports 42, and this structure can mount the fork 3 on the plurality of supports 42, so that the position adjustment of the fork 3 can be achieved directly by the movement of the supports 42, so that the fork 3 can be supported and mounted above the vehicle body 1, so that the space above the vehicle body 1 can be reasonably utilized, and a space is reserved for mounting other parts on the vehicle body 1, furthermore, the fork 3 with such a structure is only restrained by the plurality of supporting members 42, so that the fork 3 is not easily blocked by other parts on the vehicle body 1, and the plurality of first supporting members 422 and the plurality of second supporting members 424 are obliquely and rotatably mounted on the vehicle body 1, so that the plurality of first supporting members 422 and the plurality of second supporting members 424 can be integrally rotated under the action of the fork driving member 44, and the fork 3 can be driven to move up and down back and forth. While the fork carriage driver 44 is used to drive the support member 42 to move, it is preferable that a first fork carriage driver 442 is provided at a first side of the vehicle body 1 corresponding to the plurality of first support members 422, so that the driving of the plurality of first support members 422 is achieved by the first fork carriage driver 442, and at the same time, a second fork carriage driver 444 is provided at a second side of the vehicle body 1 corresponding to the plurality of second support members 424, so that the driving of the plurality of second support members 424 is achieved by the second fork carriage driver 444, and this structure enables the plurality of first support members 422 and the plurality of second support members 424 to be driven independently from each other and to distribute driving force to both sides of the vehicle body 1, so that the distribution of driving force can be made more uniform, thereby ensuring stability of the fork carriage driver 44 in driving the movement of the fork carriage 3. Of course, in another embodiment, it is also possible to provide only one fork driving member 44 at the middle portion of the vehicle body 1 to simultaneously drive the plurality of first supporting members 422 and the plurality of second supporting members 424 by one fork driving member 44, and this structure can eliminate the use of one driving device, thereby simplifying the structure of the product.

Here, the fork driving member 44 may be embodied as a telescopic member capable of driving the supporting members 42 to rotate, so that the telescopic member can be extended and contracted to realize the integral driving of the plurality of supporting members 42.

Preferably, the first supporting members 422 are equal in length and located at the same height position, and the second supporting members 424 are equal in length and located at the same height position, so that the ends of the supporting members 42 away from the vehicle body 1 can form a supporting plane parallel to the vehicle body 1, and thus the fork 3 can be stably mounted on the supporting members 42.

In any of the above embodiments, preferably, as shown in fig. 1 to 6, the forklift further comprises at least one stabilizer 5, and the at least one stabilizer 5 is installed between the plurality of first supports 422 and the plurality of second supports 424 in parallel with each other.

In these embodiments, the stabilizer 5 may be disposed between the first supporting members 422 and the second supporting members 424, so that the first supporting members 422 and the second supporting members 424 on both sides of the vehicle body 1 can be connected to each other to form a whole, and the supporting members 42 on both sides of the vehicle body 1 can be restrained from moving each other, so that the supporting members 42 on both sides of the vehicle body 1 can move synchronously, thereby ensuring the stability of the fork carriage 3 during the movement process, and making up for the defect that the supporting members 42 on both sides of the vehicle body 1 cannot be completely synchronized due to the influence of structures and the like.

Among them, preferably, as shown in fig. 2, 5 and 6, the plurality of stabilizers 5 are each provided at an end of the plurality of first supports 422 and the plurality of second supports 424 remote from the vehicle body 1, that is, when the plurality of first supports 422 and the plurality of second supports 424 are provided in a vertical plane of the forklift, it may be preferable to connect the plurality of stabilizers 5 to upper ends of the plurality of first supports 422 and the plurality of second supports 424.

In any of the above embodiments, preferably, as shown in fig. 1 to 6, the stabilizer 5 is formed by connecting a plurality of segmented rods 52, or the stabilizer 5 is an integral rod (not shown).

In these embodiments, the stabilizer 5 may be preferably provided as a rod-shaped member, but the stabilizer 5 may be a hydraulic cylinder, an electric cylinder, or the like. Preferably, a plurality of segment rods 52 are butted against each other to form a stabilizer 5, so that a long rod member can be assembled by using small short rods, thereby making the processing of the stabilizer 5 more convenient and less costly. Specifically, the stabilizer 5 may be provided, for example, as a two-piece rod including a first segment rod 52 and a second segment rod 52. Of course, the stabilizer 5 may also be an integral rod in another solution.

Wherein, preferably, a plurality of the segmented rods 52 are connected through screw threads, which can make the connection between the segmented rods 52 more convenient and reliable.

In any of the above embodiments, preferably, as shown in fig. 1 to 6, the first support 422 and the second support 424 are both telescopic members or, as shown in fig. 7 and 8, the first support 422 and the second support 424 are both non-telescopic members; and/or as shown in fig. 1-8, the first and second

fork drive members

442, 444 are both telescoping members.

In these embodiments, the first support 422 and the second support 424 may be provided as telescopic members, so that the height position adjustment of the yoke 3 can be realized by the unified extension and contraction of the plurality of supports 42, so that the height adjustment and the front-rear position adjustment of the yoke 3 can be simultaneously realized by the plurality of supports 42, and the structure of the adjustment assembly 4 can be simplified. The first and second

fork drive members

442, 444 are also preferably telescoping members so that the telescoping of the telescoping members can be used to drive the plurality of support members 42. Of course, in other aspects, the driving of the plurality of supports 42 may be accomplished by other structures. Further, the first support 422 and the second support 424 may be non-telescopic members, such as a general rod structure, and in this case, the position adjustment of the yoke 3 may be achieved only by the rotation of the plurality of supports 42.

Wherein, preferably, the first and

second supports

422 and 424 are both hydraulic or electric cylinders, and the first and second fork carriage drives 442 and 444 are both hydraulic or electric cylinders.

The use of hydraulic cylinders for the support member 42 and the fork carriage drive 44 also enhances the support of the support member 42 and the fork carriage drive 44, since the hydraulic cylinders can withstand a relatively large thrust, thus enabling the fork carriage 3 to carry heavy articles. Meanwhile, as the space on the forklift is limited, the telescopic part can preferably adopt a multi-stage hydraulic cylinder.

In one embodiment, when the first support 422 and the second support 424 are both telescopic members, and the first fork driving member 442 and the second fork driving member 444 are both telescopic members, the first fork driving member 442 may be vertically disposed between the plurality of first support 422, so that the plurality of first support 422 may be supported and driven from the middle of the plurality of support members 42. And when the first and

second supports

422 and 424 are both non-telescopic members, the driving and supporting of the support 42 may be achieved from the rear or side portions of the first and

second supports

422 and 424.
