<p>A continuous rotary link (10) to be mounted between an articulated boom (14) of a vehicle and a multifunction head (18) is described herein. The continuous rotary link (10) includes a fixed assembly (12) mounted to the articulated boom (14) and a rotatable assembly (16) rotatably mounted to the fixed assembly (12) and to which the multifunction head (18) may be mounted. Fluid transmission circumferential channels (64, 66, 68) are provided between the fixed and rotatable assemblies (12, 16) to allow hydraulic fluid to be transferred between these two assemblies even during the relative rotation of the rotatable assembly (16) with respect to the fixed assembly (12). The continuous rotary link also includes electrical connectors (94, 96, 98, 100) so mounted to the fixed and rotatable assemblies (126, 128, 130, 132) as to remain in electrical contact during the rotation of the rotatable assembly (16). Electrical signals may therefore be exchanged between the fixed and rotatable assemblies (12, 16) during the continuous rotation of the rotatable assembly (16).</p> |
