To provide a remote control terminal that can prevent improper operation during remote control of a mobile crane and easily and simply make remote control of the mobile crane, and a work vehicle comprising a remote control terminal.SOLUTION: The work vehicle comprises: a terminal-side GNSS receiver that receives a distance measurement signal from a GNSS satellite and calculates a current position of a remote control terminal 32; a suspended load movement operation tool 35 that makes remote control of a crane on the basis of an operation directional reference Bo; and a terminal-side control device that is configured to be able to communicate with a control device of the crane and controls operation of the remote control terminal 32. The terminal-side control device acquires a current position of a tip of a boom from the control device of the crane, acquires a current position of the remote control terminal 32 from the terminal-side GNSS receiver of the remote control terminal 32, and sets the operation directional reference Bo on a line connecting the current position of the tip of the boom to the current position of the remote control terminal 32.SELECTED DRAWING: Figure 5
【課題】動式クレーンの遠隔操作時における誤操作を防止し、移動式クレーンの遠隔操作を容易かつ簡単に行うことができる遠隔操作端末および遠隔操作端末を備える作業車両を提供する。【解決手段】GNSS衛星からの測距信号を受信し遠隔操作端末32の現在位置を算出する端末側GNSS受信機と、操作方向基準Boに基づいてクレーンを遠隔操作する吊り荷移動操作具35と、クレーンの制御装置と通信可能に構成され、遠隔操作端末32の作動を制御する端末側制御装置と、を備え、端末側制御装置が、クレーンの制御装置からブームの先端の現在位置を取得し、遠隔操作端末32の端末側GNSS受信機から遠隔操作端末32の現在位置を取得し、ブームの先端の現在位置と遠隔操作端末32の現在位置とを結ぶ線上に操作方向基準Boを設定する。【選択図】図5
