次に、図６を参照して板Ｐを運搬するための作業手順を説明する。なお、以下の作業は、運搬車１に連結されているフォークリフト５に搭乗しているオペレータが、操作装置５３を操作することにより行われる。 Next, a work procedure for transporting the plate P will be described with reference to FIG. The following operations are performed by the operator on the forklift 5 connected to the carrier 1 operating the operating device 53.

運搬車１の爪１４Ｃ，１４Ｄが脚部８２の非接地面８２Ａよりも低い状態でフォークリフト５を前進させ、図６（Ａ）に示すように、爪１４Ｃ，１４Ｄを地面と非接地面８２Ａとの間に差し込み、全ての脚部８２の下に爪１４Ｃ，１４Ｄが位置したときフォークリフト５の走行を停止させる。次いで、図６（Ｂ）に示すように、支持機構１４を上昇させ、爪１４Ｃ，１４Ｄで架台８を持ち上げる。このとき、支持機構１４の上昇と同時にフォーク５１を上昇させることで、架台８が前後方向Ｘに傾かないようにする。次いで、図６（Ｂ）中の破線で示すように制震機構１５を動作させ、パッド１５Ａで架台８に対して板Ｐを押さえつける。そして、４つの制震機構１５のパッド１５Ａにより板Ｐが架台８に対して押さえつけられている状態で、フォークリフト５を後進させて、運搬車１を牽引する。こうして、フォークリフト５により牽引される運搬車１は、架台８および架台８に立てかけて載せられている板Ｐを運搬する。 The forklift 5 is advanced in a state where the claws 14C and 14D of the carrier 1 are lower than the non-contact patch 82A of the leg 82, and the claws 14C and 14D are connected to the ground and the non-contact patch 82A as shown in FIG. When the claws 14C and 14D are located under all the legs 82, the forklift 5 is stopped running. Next, as shown in FIG. 6B, the support mechanism 14 is raised, and the gantry 8 is lifted by the claws 14C and 14D. At this time, by raising the fork 51 at the same time as raising the support mechanism 14, the gantry 8 is prevented from tilting in the front-rear direction X. Next, the vibration control mechanism 15 is operated as shown by the broken line in FIG. 6B, and the plate P is pressed against the gantry 8 by the pad 15A. Then, with the plate P pressed against the gantry 8 by the pads 15A of the four vibration control mechanisms 15, the forklift 5 is moved backward to pull the carrier 1. In this way, the carrier 1 towed by the forklift 5 carries the gantry 8 and the plate P leaning against the gantry 8.

目的地まで板Ｐを運搬すると、フォークリフト５の走行を停止させ、制震機構１５を動作させ、図６（Ｂ）中の実線で示すように板Ｐが架台８に対して押さえつけられないように板Ｐからパッド１５Ａを離間させる。そして、図６（Ａ）に示すように、支持機構１４を下降させ、架台８を接地させる。このとき、支持機構１４の下降と同時にフォーク５１を下降させることで、架台８が前後方向Ｘに傾かないようにする。そして、地面と非接地面８２Ａとの間から爪１４Ｃ，１４Ｄを抜くように、フォークリフト５を後進させる。 When the plate P is transported to the destination, the running of the forklift 5 is stopped, the vibration control mechanism 15 is operated, and the plate P is not pressed against the gantry 8 as shown by the solid line in FIG. 6 (B). The pad 15A is separated from the plate P. Then, as shown in FIG. 6A, the support mechanism 14 is lowered to ground the gantry 8. At this time, by lowering the fork 51 at the same time as lowering the support mechanism 14, the gantry 8 is prevented from tilting in the front-rear direction X. Then, the forklift 5 is moved backward so as to pull out the claws 14C and 14D from between the ground and the non-contact patch 82A.

本実施形態では次の効果が得られる。
（１）運搬車１は、昇降用油圧アクチュエータ１６により支持機構１４を昇降させることで、板Ｐが立てかけて載せられている架台８を持ち上げることができ、架台８を持ち上げた状態でフォークリフト５により牽引されることにより、架台８を運搬することができる。このため、架台８に車輪を設けることなく板Ｐとともに架台８を運搬できる。 The following effects can be obtained in this embodiment.
(1) The carrier 1 can lift the gantry 8 on which the plate P stands upright by raising and lowering the support mechanism 14 by the lifting hydraulic actuator 16, and the forklift 5 can lift the gantry 8 while the gantry 8 is lifted. By being towed, the gantry 8 can be transported. Therefore, the gantry 8 can be transported together with the plate P without providing wheels on the gantry 8.

（２）運搬車１は、昇降用油圧アクチュエータ１６内の油圧の変動を抑制するアキュムレータ１８Ａ，１８Ｂを備えているため、運搬車１の走行に伴う支持機構１４の振動を抑制できる。このため、運搬車１がアキュムレータ１８Ａ，１８Ｂを備えていない構成に比べて、運搬時に板Ｐが割れることを抑制できる。 (2) Since the transport vehicle 1 includes accumulators 18A and 18B that suppress fluctuations in the hydraulic pressure in the lifting hydraulic actuator 16, vibration of the support mechanism 14 accompanying the traveling of the transport vehicle 1 can be suppressed. Therefore, as compared with the configuration in which the transport vehicle 1 does not include the accumulators 18A and 18B, it is possible to prevent the plate P from cracking during transportation.

（３）運搬車１は、制震用油圧アクチュエータ１７内の油圧の変動を抑制するアキュムレータ１９を備えているため、運搬車１の走行に伴う制震機構１５の振動を抑制できる。このため、運搬車１がアキュムレータ１９を備えていない構成に比べて、運搬時に板Ｐが割れることを抑制できる。 (3) Since the transport vehicle 1 is provided with an accumulator 19 that suppresses fluctuations in the hydraulic pressure in the vibration control hydraulic actuator 17, it is possible to suppress vibration of the vibration control mechanism 15 that accompanies the traveling of the transport vehicle 1. Therefore, as compared with the configuration in which the transport vehicle 1 does not include the accumulator 19, it is possible to prevent the plate P from cracking during transportation.

（４）運搬車１は、検知装置２３による検知結果を表示する表示装置２４を備えているため、オペレータは、表示装置２４を参照して、板Ｐが架台８に対して押さえつけられている状態であるか否かを確認することができる。 (4) Since the transport vehicle 1 includes a display device 24 that displays the detection result by the detection device 23, the operator refers to the display device 24 and is in a state where the plate P is pressed against the gantry 8. It is possible to confirm whether or not it is.
