SECTION 5 - MECHANICAL SYSTEMS
Mechanical components (including impact) with
and systems shall be designed appropriate durability and safety
to withstand service loads
readily accessible for repair, maintenance, and inspection. Replacement seals shall be readily obtainable. Major components shall have lifting lugs.
The following mechanical requirements/features. The
systems descriptions Manufacturer is invited
are intended to be minimum to highlight the capabilities and
features of the Forklift truck system(s) proposed.
Diesel Engine System
The Forklift trucks shall be powered by a USA EPA Tier III compliant electronic fuel controlled diesel engine, manufactured by Cummins or ASPA approved equal, capable of supplying adequate power for all Forklift truck operations (simultaneous hoist (or lower) and travel operation with rated load) without limiting design accelerations and speeds. The diesel engine and related equipment shall be of high quality and shall be the latest product of manufacturers specializing and regularly engaged in the design and manufacture of such equipment.
The engine shall also provide adequate power for the hydraulic (or ASPA approved equal) magnet system generator – however, the magnet system shall only require power when all other Forklift truck motions are stopped.
The engine shall run smoothly and quietly at all operating speeds, with a clear exhaust, up to and including full load, without overheating.
Gages and alarms/alerts shall be provided in the operator's cab to indicate: (Minimum Requirements)
Engine coolant temperatures
Fuel level gage
Low oil pressure/hot engine alarm
Power Transmission System
5.3.1. A durable heavy duty power transmission system with torque converter, transmission, drive shafts, and drive axles shall be provided. The system shall allow for automatic power shift operation in forward and reverse directions and shall be capable of "inching". The transmission system shall permit full speed forward and reverse operation of the Forklift trucks with rated load.
