Press Release Summary:
Split System/High Boy Kneeling Module consists of manifold with machined aluminum-anodized body that houses 4 pneumatic poppet valves which inflate/exhaust axle-mounted air bags. Upon actuation, module routes compressed air, in tandem with kneeling position requirements, to lower suspension for passenger loading and then returns vehicle to proper travel height. Solution provides seamless split-level, left/right/complete kneel, and high-boy functions for safe bus passenger access.
Original Press Release:
Parker Kneeling Bus Module Facilitates Seamless Passenger Access
RICHLAND, MICHIGAN, APRIL 10, 2007 - The Pneumatic Division of Parker Hannifin Corporation (NYSE:PH) introduces a new, easy-to-install, lightweight Split System/High Boy Kneeling Module designed to provide seamless split-level, left/right/complete kneel and high-boy functions for easy, safe bus passenger access. Working closely with bus/coach manufacturers, Parker has developed the pneumatic Kneeling Module designed to exhaust/refill air bags on demand with minimum delay.
A radical improvement over existing technologies which typically require manufacturers to assemble an array of pneumatic valves, connectors and other components into a complete system, the Parker Kneeling Module integrates pneumatic components to simplify installation and maintenance while providing a full range of kneeling capabilities for large passenger vehicles.
Pre-fit to customer specifications and factory pre-lubricated, the module is designed to go from box to bus with minimum installation hassles. The Kneeling Module is easy to install with all functions integrated into a lightweight machined aluminum anodized body for maximum durability.
Solid housing with integrated valves - combined with heavy-duty 22mm grommet style mobile solenoids for valve electrical actuation, along with exhaust protectors - maximizes system reliability for bus/coach applications.
The new module consists of a durable, lightweight manifold with machined aluminum-anodized body, which houses four pneumatic poppet valves that inflate/exhaust axle-mounted air bags. At the flick of a switch, the module routes compressed air, in tandem with kneeling position requirements, to quickly lower suspension for passenger loading and then returns vehicle to over-the-road travel height.
The combination of solid housing, poppet valves (1.4 Cv flow) and heavy-duty solenoids results in a durable unit with built-in dirt, water and salt resistance. Flapper-type exhaust protectors permit air flow to atmosphere, while keeping contaminants out to heighten its reliability factor. The system also features specially designed sealing made to withstand operating temperatures from -40° to 122°F and provide excellent resistance to aggressive fuels/oils. The module possesses operating pressures from 60 to 150 psi with standard coil voltages available in both 12VDC and 24VDC versions. Other voltages are available through special order.
With full tech backup/support from product managers and trained technical service experts, the Kneeling Module adheres to precise specifications that make the system robust enough to handle a wide variety of operating environments. All components are constructed for stability and volumetric efficiency while incorporating simple, low-maintenance technology that provides pneumatic solutions for transportation.
The Pneumatic Division designs and manufactures air control valves, vacuum products, air preparation components and specialty products for a myriad of industry segments.
With annual sales exceeding $9 billion, Parker Hannifin is the world's leading diversified manufacturer of motion and control technologies and systems, providing precision-engineered solutions for a wide variety of commercial, mobile, industrial and aerospace markets. The company employs more than 57,000 people in 43 countries around the world.
