Fabreeka pads, washers and bushings have long been used to eliminate objectionable structure-borne noise in buildings from the operation of passenger elevators. The installation of the pad, washer and bushing combination completely isolates the transmission path of structure-borne noise and vibration. Roller Guide Tires - Fabreeka pad material is used as roller guide tires attached to the side of the cab to bear against the stationary frame to cushion side impact. Excellent wearing characteristics combined with the vibration and shock absorbing capabilities of the Fabreeka pad, make it an ideal material for this application.Elevator Car Isolation - Fabreeka pads, washers and bushings are used to insulate the metal contacts between the car crosshead (hoisting cable attachment) and the car body. This prevents the transmission of vibration from the hoisting machinery through the cables to the car.Car and Counterweight Rail Brackets - Fabreeka pads, washers and bushings are placed between the rail brackets and building structure to provide structure-borne noise isolation.Motor Hydraulic Pump Unit - Fabreeka pads, washers and bushings are used to isolate the bolted connections to the supporting structure. In some instances, Fabcel pads can also be used under lighter loads and when disturbing frequencies are lower.It is important to remember that any metal-to-metal or metal-to-concrete point of contact can transmit structure-borne noise. Fabreeka pads, washers and bushings are recommended at all such points to prevent this vibration "short-circuit".Learn MORE »
Fabreeka Crane Rail pad material is used to reduce vibration, stresses and mechanical wear and tear associated with bridge, gantry and ore crane operation, thereby reducing maintenance costs.Fabreeka Crane Rail pads are designed to relieve girder stress, improve load distribution, eliminate mechanical wear of flange or cover plates, dampen vibration and reduce noise. The laminated thermoset plastic (LTP) surface of the crane rail pad improves wear resistance, restricts lateral movement and provides a low coefficient of friction support for the rail. Tests performed by independent sources have shown up to 40% reduction in runway beam web stress and noise levels reduced substantially when using Fabreeka Crane Rail pad.Learn MORE »
Fabreeka has designed a number of "soft support systems" (SSS) using standard and custom pneumatic isolators for ground vibration testing (GVT) of aircraft. To obtain accurate results during GVT, the modal testing of the aircraft requires simulation of a "free-free" condition. To achieve this condition, Fabreeka works with the structural and dynamics testing groups of aircraft manufacturers to design the required SSS for the GVT.The pneumatic isolators support and decouple the aircraft from the ground when the aircraft is undergoing dynamic testing and modal/flutter analysis. The role of the system is especially important in identifying structural resonances and validating flutter models. The SSS can also include a jacking system to lift the aircraft off of its landing gear.Learn MORE »
