Abstract: A package (1) includes a bag (20) and a sheet laminate (10) packaged in the bag (20). The sheet laminate (10) includes a first fiber sheet (11) including a first fiber including a PET resin having a melting point higher than 230° C., and a second sheet (12) including a thermoplastic resin having a melting point of 230° C. or lower. The sheet laminate (10) includes a joined portion (30) in which the first fiber sheet (11) and the second sheet (12) are joined adjacently to each other. In the joined portion (30), constituent resin of the first fiber sheet (11) is embedded in the thermoplastic resin constituting the second sheet (12). The present invention also provides a production method of the package.

Abstract: A traveling operation device of a crawler-type aerial work platform including an operation of an enable switch by one hand is provided. An enable switch and a changeover switch are disposed on an operation rod main body at positions where the enable switch and the changeover switch are operable by fingers gripping the operation rod main body of an operation rod during traveling so that all of them are operable by one hand. When a controller receives a switching command signal in accordance with the operation of the changeover switch in a state of usual travel control according to tilt of the operation rod in front-rear and right-left directions, the controller stops the usual travel control to transition the usual travel control to spin turn control that rotates motors in mutually opposite directions and turns the platform on the spot.

Abstract: Provided is a travel operation device for a crawler aerial work vehicle equipped with an operation panel that can be operated with one hand and that provides stable operating conditions even when swayed from side to side. A travel operation device 10 comprises an operation panel 11 that is disposed on the deck 4 of a self-propelled crawler aerial work vehicle 1 and a controller 70 that controls the rotation of a left-side motor 60a, which drives a left-side endless track, and a right-side motor 60b, which drives a right-side endless track, according to the operation of an operating stick 20 that is disposed on the operation panel 11. The operating stick 20 of the operation panel 11 is composed of: an operating stick body 21 that can be tilted only in one axial direction back and forth from the neutral position; a left-swivel switch 24; a right-swivel switch 25; and an enable switch 22 that enables the operation of the switches.

Abstract: An operation panel for aerial work vehicles that can be operated by one hand and removable from a deck and used as a remote control. The operation panel body of an operation panel equipped with a driving operation device is detachably mounted on a deck, the driving operation device being provided with: a control stick capable of tilting back/forth and left/right from the neutral position, and that causes an aerial work vehicle to perform a traveling operation to move forward, backward, and stop as the control stick tilts back/forth and a steering operation to steer as the control stick tilts in the left/right directions; and an enable switch that is located in a position where the enable switch can be pressed by the same fingers as those gripping and tilting the control stick, and that enables the traveling operation and steering operation only when pressed.
