Abstract
A crane apparatus includes an upstanding mainframe and a boom unit that is supported for rotation on the mainframe through a range of movement of about 500.degree.. The crane is provided with a plurality of fluid transmission lines having first ends fixed relative to the mainframe and second ends fixed relative to the boom unit. An elongated guide tube supports the lines relative to the boom unit and presents a lower end that is spaced radially from the axis of rotation of the boom unit for sweeping the lines along an arcuate path around the axis as the boom unit is rotated, coiling the lines beneath the guide element to inhibit kinking. This management of the lines reduces the amount of twisting per unit length of line and prevents kinking within the range of allowed movement of the boom unit.
