REV: 04-29-25 LF OUTRIGGER/AERIAL INTERLOCK The aerial hydraulic system shall include an interlock feature that will prevent the accidental operation of the outriggers during aerial operation. This interlock shall also prevent accidental operation of the aerial device prior to the outriggers being properly deployed. In the event of electrical failure, the operator shall be able to override the hydraulic system to operate the aerial device or outriggers for continuous, uninterrupted operation. A 5,000 psi hydraulic oil pressure gauge shall be provided and installed at the override location to monitor the overall pressure of the hydraulic system. LIFT, EXTENSION AND ROTATION HYDRAULIC CONTROL VALVE A three-function hydraulic proportional valve bank shall control ladder functions. The valve shall be located at the turntable console area with access for maintenance as needed. OUTRIGGERS Two (2) independently controlled “out and down” H-Style outriggers shall be provided, forward of the body compartmentation, at the front of the trailer. The extension of the horizontal outrigger beams shall provide a 16’ outrigger stance. Five (5) slide pads shall be provided for each outrigger beam assembly to provide smooth operation and to extend the life of the outrigger. For ease of service, the vertical jack cylinders shall be designed so they can be removed from the top. Designs that require the removal of the horizontal beams or dropping the cylinder out the bottom shall not be acceptable. OUTRIGGER SYSTEM HYDRAULIC CONTROL VALVES A directional control valve that is designed for parallel hydraulic circuit operations shall control the outrigger cylinder system. This valve shall be modular in design so that individual sections can be replaced in the field, rather than complete valve assemblies, thus reducing maintenance costs. Each valve shall be equipped with a heavy-duty electric solenoid for electric control of the outrigger from the remote operator's station. OUTRIGGER CONTROL STATIONS Two (2) illuminated electronic outrigger control stations shall be provided, one (1) on each side of the trailer gooseneck forward of each outrigger. For safety, ease of deployment and operational speed, the outrigger controls shall be of the electric over hydraulic proportional type with manual overrides immediately accessible. The outrigger beam and jack actuator controllers shall be enclosed in a recessed compartment to protect each control from damage or accidental movement. The controls shall be located such that the operator can see the outrigger that is being operating. Body designs that block the view of the outriggers from the control station shall not be acceptable. The outrigger control functions shall be operated independently, so that the vehicle may be set up in restricted areas or on uneven terrain.
