1. Hydraulic Digger Derrick Truck, built in accordance with standard specifications and to include the following features: Minimum Features requirements: Unit A. Maximum Sheave Height: 46.4 ft B. Maximum Horizontal Reach: 37.3 ft C. Maximum Digging Radius: 26.7 ft D. Maximum Capacity (ANSI Rating Classification): 12,902 lb E. Articulation: 80 degrees above horizontal to 20 degrees below horizontal F. Winch: 15,000 pound bare drum capacity turntable winch with 8.625 inch diameter drum to comply with ANSI 10.31 Section 4.10.4 for synthetic rope or 15,000 pound bare drum capacity boom tip winch. High torque hydraulic motor drives a self-locking worm gear winch. Counterbalance valves on motor provide reliable load holding G. Insulated: 46 kV and below H. Hydraulic Overload Protection System: activates when unit is exposed to overload condition. System prevents actuation of all functions that could add to the overload condition including: -Boom Lower -Intermediate Boom Extend -Third Stage Boom Extend -Winch Raise -Auger Dig System automatically resets when overload condition is relieved. I. Load Indicator Gauge: located at the main control panel, displays the percentage of total allowable lifting capacity being utilized. By use of this gauge, the operator is aware of the hydraulic and structural design rating of the derrick and proximity to the limits during operation. J. Hydraulic Side Load Protection: relieves overload conditions by allowing rotation system to back drive. K. Continuous Rotation with high capacity worm gear drive gearbox L. Electronic CAN Controls: Intuitive electronic controls with superior metering. Includes a diagnostic port which by connecting a handheld service tool, provides troubleshooting code readouts and the ability to calibrate function speeds and control sensitivity. Electric controls eliminate the risk of high pressure hose leaks near the operator and leak points are minimized throughout the machine. N. Indicator Light Panel at Control Station(s): indicators for hot oil, change hydraulic oil filter, Rotafloat active (if equipped), and check system light with diagnostic capabilities
