この考案は、走行装置を具備した車台上に設け
るクロスリンク式のリフト装置により荷台を略水
平状態で昇降させることで、荷物を高所に積み揚
げる作業等を可能とした移動台車に関するもので
ある。[Detailed description of the invention] This invention enables tasks such as loading and unloading cargo to high places by raising and lowering the loading platform in a nearly horizontal state using a cross-link type lift device installed on the chassis equipped with a traveling device. This relates to a mobile trolley.
原動機等を内蔵する操縦部を車台の前後一側に
設け、他側に荷台を設けた移動台車では、荷物を
荷台に積込んだ状態で台車の前後バランスが良く
なるようにするためには、空荷の状態で操縦部側
に前後重心がくるようにすれば良いのであるが、
これでは、空荷の状態での台車の走行性能が悪く
なる。 In a mobile trolley that has a control unit containing a built-in motor, etc. on one side of the front and back of the chassis and a loading platform on the other side, in order to improve the front-rear balance of the trolley when cargo is loaded on the platform, It would be fine if the front and back center of gravity was on the control side when unloaded.
This deteriorates the running performance of the cart in an empty state.
それゆえに、前後重心位置を操縦部側へ片寄せ
ることには限度がある。その為、荷台に重い荷物
を積込んだ状態では、前後重心位置が荷台側へ片
寄る傾向にある。このように前後重心が荷台側へ
片寄つた状態に於いて、荷台が低位置にある場合
はさほど危険は生じないのであるが、この荷台が
リフト装置によつて高く上昇すれば台車は荷台側
へ転倒し易くなる恐れが生じる。又、荷物を高所
に揚げた後で適宜位置に降ろす際、殆ど荷物は荷
台の操縦部側からではなくて、荷台端に移動させ
てから降ろすために重心位置は一層荷台端に片寄
り、さらに転倒し易くなるのである。 Therefore, there is a limit to shifting the longitudinal center of gravity toward the control section. Therefore, when a heavy load is loaded onto the cargo platform, the longitudinal center of gravity tends to shift toward the cargo platform. In this state where the front and rear center of gravity is biased toward the loading platform, there is not much danger if the loading platform is in a low position, but if the loading platform is raised higher by the lift device, the truck will move toward the loading platform. There is a risk of falling easily. Also, when lowering cargo to an appropriate location after hoisting it to a high place, most of the cargo is moved to the edge of the platform and then lowered, rather than from the control side of the platform, so the center of gravity is further shifted toward the edge of the platform. This makes them even more likely to fall.

に構成してなる移動台車の構成とする。 In view of the above-mentioned circumstances, this invention was devised for the purpose of raising a loading platform using a lift device and safely loading and unloading cargo at the raised position, and is constructed as follows. That is, the traveling device 1
A control unit 4 is provided along with a prime mover 3 on one front and rear side of a vehicle chassis 2 equipped with a chassis 2, and a cross-link type lift device 8 in which a pair of links 5 and 6 are rotatably connected by a pivot shaft 7 is installed on the other side. In a movable trolley equipped with a loading platform 9 that moves up and down horizontally, the lower end of one link 5 is rotatably pivoted to the opposite side of the control section 4 of the chassis 2, and the upper end of the link 5 is placed on the side of the operating section 4 of the loading platform 9. The lower end of the link 6 on the other side is slidably connected along a guide rail provided on the side of the control section 4 of the vehicle platform 2, and the upper end of the link 6 is connected to the control section of the cargo platform 9. 4, when the links 5 and 6 are rotatably supported on the opposite side, the pivot shafts 7 of both links 5 and 6 are positioned below the longitudinal center of the links 5 and 6, and
The lower end of the link 5 on one side is slidably connected along a guide rail provided on the opposite side of the control section 4 of the vehicle platform 2, and the upper end of the link 5 is rotatably supported on the side of the control section 4 of the loading platform 9, Connect the lower end of the link 6 on the other side to the chassis 2
When the upper end of the link 6 is slidably connected along a guide rail provided on the opposite side of the operating section 4 of the loading platform 9, both links 5,

に比較して何等コストアツプ要因がないにも拘ら
ず、前記の如き有益な効果を有すのである。 By configuring this invention in this way, it has the following technical effects. That is, when a heavy load is loaded onto the loading platform 9, the longitudinal center of gravity tends to be biased toward the loading platform 9, and the loading platform 9 is moved approximately horizontally by the lift device 8 while the longitudinal center of gravity is biased toward the loading platform 9.
However, in this invention, when the loading platform 9 is raised, the loading platform 9 moves appropriately toward the control section 4, which is dangerous.
It is possible to maintain good front-to-back balance of the trolley and prevent the above-mentioned overturning. In addition, when loading and unloading cargo from one side of the loading platform 9 after raising the loading platform 9, in most cases loading and unloading is from the end of the loading platform 9 opposite to the control section 4 side, so the center of gravity is located further toward the end of the loading platform 9. However, with the above-described structure, the loading platform 9 moves in a direction that prevents it from falling over, allowing safe loading and unloading operations. Moreover, the configuration for appropriately moving the cargo platform 9 toward the control section 4 side simply moves the position of the connecting pivot shaft 7 of both links 5, 6 that constitute the lift device 8 from the longitudinal center of both links 5, 6. Although it is a simple device that is installed at appropriate distances and has no cost increase factor compared to a conventional lift device in which the centers of both links 5 and 6 are connected and supported by a shaft, it has the beneficial effects described above. be.
更に、上記の如く荷台９を操縦部４側へ移動さ
せて機体を安定させることができるものでありな
がら、該クロスリンク方式の特長である大きな昇
降量を同時に確保できるものである。 Furthermore, while the cargo platform 9 can be moved toward the control section 4 to stabilize the aircraft as described above, it is also possible to ensure the large amount of elevation that is a feature of the cross-link system.
