Claims20
A method associated with an idle managed and air conditioned truck-mounted aerial work platform, the method comprising the steps of:
- providing a first source of rotary power for driving a first shaft of an air conditioning compressor, where said first source of rotary power has a first connection with an engine of a vehicle;
- providing a second source of rotary power for driving the first shaft of the air conditioning compressor on the vehicle;
- driving a hydraulic pressure generator which has a first electrical connection to a source of stored electric energy;
- causing said second source of rotary power for driving the air conditioning compressor to drive said air conditioning compressor when said first source of rotary power for driving the air conditioning compressor is unavailable;
- and
- said second source of rotary power for driving said air conditioning compressor is configured to utilize said first source of rotary power for driving the air conditioning compressor, when said engine of the vehicle is running, to charge said source of stored electric energy.
A system associated with an idle managed and air conditioned vehicle-mounted, hydraulically manipulated and electrically insulated aerial work platform, the system comprising:
- a compressor drive system for providing an alternate source of rotary movement for driving a compressor on a vehicle where a primary source of rotary movement for driving the compressor has a first connection with a motor of the vehicle, wherein said first connection with a motor of the vehicle provides rotary movement through transmission of rotary movement;
- a compressor drive system controller configured to cause said compressor drive system to drive said compressor when said primary source of rotary movement is unavailable;
- an electric storage for providing electric energy to said compressor drive system;
- a primary hydraulic pressure generator with a primary source of driving the primary hydraulic pressure generator has a second connection to the of the vehicle;
- and
- an auxiliary hydraulic pressure generator with a primary source of driving the auxiliary hydraulic pressure generator has a first electrical connection to a source of stored electric energy.
A system associated with an idle managed and air conditioned vehicle-mounted, hydraulically manipulated and electrically insulated aerial work platform, the system comprising:
- a compressor system for providing an alternate source of power for a compressor on a vehicle where a primary source of rotary power for driving the compressor has a first connection with motor of the vehicle;
- a compressor system controller configured to cause said compressor system to drive said compressor when said primary source of rotary power is unavailable;
- an electric storage device for providing electric energy to said compressor drive system;
- a first pump with a primary source of driving the first pump having a second connection to the motor of the vehicle;
- and
- a second pump with a primary driving source having a first electrical connection to a source of stored electric energy.
A method associated with an idle managed and air conditioned truck-mounted, hydraulically manipulated and electrically insulated aerial work platform, the method comprising the steps of:
- providing an alternate source of power for driving a compressor on a vehicle where a primary source of power for driving the compressor has a first connection with motor of the vehicle;
- driving an auxiliary hydraulic pressure generator which has a first electrical connection to a source of stored electric energy;
- causing said alternate source of power for driving a compressor to drive said compressor when said primary source of power for driving the compressor is unavailable;
- and
- said alternate source of power for driving said compressor is configured to utilize said primary source of power for driving the compressor, when said motor of the vehicle is turning, to charge said source of stored electric energy.
