With safety as Priority #1, use of polymer springs eliminates a potential source of injury and safeguards workers during equipment assembly and installation. Polymer springs are much safer to install compared to steel coil springs because their lowered stored energy reduces the risk of injury and damage due to uncontrolled release.
Parker's experienced engineers utilize state of the art design tools including nonlinear Finite Element Analysis (FEA) to design and validate material and geometry combinations that produce optimal force deflection curves to meet application requirements.
In typical track tensioner spring configurations of light-weight mobile equipment such as skid loaders, steel coil springs provide tensioning for the track as it encounters major obstacles such as pot-holes and boulders. During installation of the spring tensioner assemblies the force required to compress the steel spring is significant. Should any error or difficulty cause an uncontrolled release of the steel coil’s stored energy, there is a high potential for severe damage to personnel and property.
With polymer springs, this danger is virtually eliminated. As polymer springs are installed, the compressive energy is stored within the polymer chains.
Parker’s extensive range of materials and knowledge of material properties give us a unique advantage in selecting the appropriate polymer for your application. Polymer springs are manufactured from a variety of thermoplastic elastomers including our proprietary Resilon® polyurethane (TPU), PolyMyte® (TPCE), and other custom engineered materials.
