2 Worldwide E ontrols, Inc. World Headquarters Farmington, Michigan U.S E Stossdampfer GMH Langenfeld, Germany E ontrols Japan Ltd. hiba Prefecture, Japan E ontrols International Merseyside, United Kingdom Founded over 35 years ago, E ontrols, Inc. is recognized as the world leader in the design and manufacture of deceleration devices for a wide variety of industries. Facilities are located in the United States, England, Germany and Japan together with extensive distribution throughout the world. E is able to provide an excellent and responsive sales and support network. The E ontrols product line includes gas springs, hydraulic dampers, industrial shock absorbers, stacker crane shocks as well as crane and heavy industrial shock absorbers, velocity controls, rotary dampers and TUUS elastomer bumpers. E s innovations include adjustable and selfcompensating shock absorbers as well as files and simulation software for shock absorber applications and product selection. E ontrols, Inc. is a certified ISO 91:2 manufacturer. The E line of gas springs is ideal for counterbalancing loads to provide assistance in both lifting and lowering covers, guards and panels, as well as limiting the rate at which heavy covers, etc. can be moved. E ontrols pplications epartment is one of the most advanced in the industry. Engineers are available to assist you by providing full technical support for your gas spring and hydraulic damper application requirements. The E ontrols pplications epartment can be reached at E ontrols, Inc. Phone: Fax: shocks@acecontrols.com

3 Function, onstruction and Operation, Gas Springs Function In every action involving a lifting or lowering motion, e.g. when opening a hatch lid, there are masses in movement which must be controlled. If this is ignored, then the kinetic energy caused by the mass in motion can result in considerable damage. There are several ways that E offers to control this motion. a) Shock absorbers - used when no return assistance is required and no restriction of the velocity is required, control being provided shortly before the mechanical components make contact. b) Velocity controls - used when no return assistance is required, and control of velocity throughout the motion is required. c) Rotary dampers - used in light load situations requiring no return assistance and controlled velocity throughout the motion. d) Gas springs - used when return assistance or load support (counterbalance) is required throughout the motion. The gas springs can be provided in a wide range of body sizes, stroke lengths and the force provided can be specified to suit the specific application. The extension and compression velocities can also be customized on request. Integral grease chamber for increased life Oil zone filling for end position damping and lubrication Precision steel tube powder coated for corrosion protection eram-pro coated steel piston rod onstruction and Operation Metering orifice for defined extension and compression velocities Filled with high pressure nitrogen gas Various mounting options available (adjustment valve available) E gas springs are maintenance free self-contained systems which are filled with high pressure nitrogen gas to a defined pressure. They also contain a small quantity of oil to provide end position damping. uring operation, the nitrogen gas flows through the metering orifice and allows the load to be lowered in a controlled manner. The force of the gas spring works against the weight and prevents it from accelerating and damaging mechanical components on closure. Upon reversal the nitrogen flows back through the piston orifice and the gas spring force assists the action, reducing the effort required to reset the mechanism. The opening and closing speeds can be varied by altering the size of the metering orifice. For cushioning on the extension stroke, mount with the rod down. For cushioning on the compression stroke, mount with the rod up. n integral grease chamber behind the rod seals ensures lasting lubrication which can increase the life of E gas springs by at least 1% compared to other products on the market. The eram-pro coated steel piston rod and powder coated precision steel body ensure excellent corrosion protection and provide a long maintenance free working life. The wide variety of available mounting accessories provide mounting versatility and options. 3 E ontrols, Inc. Phone: Fax: shocks@acecontrols.com

5 W alculations and Mounting Instructions, Gas Springs Use the following application parameters to calculate a suitable E gas spring: 1. Weight of the lid or flap 2. Position of the center of gravity 3. Sketch of the application layout Symbols used: W Force due to weight of the lid R W Radius of center of gravity L G istance to gas spring s enter of gravity Pivot point n Number of gas springs in parallel lbs (kg) lbs (kg) - L G R W F 1 W s Example W = 9 lbs (41 kg) R w = 3 in (762 mm) L G = 6 in (152.4 mm) n = 2 F 1 = F 1 = 225 lbs (1 N) asic formula for calculating required extension force: F 1 W L G.. R W n lbs (N) hosen force: F 1 = 225 lbs (1 N) hosen gas spring: GS The basic formula given enables an approximate calculation of the required gas spring force for one mounting position geometry. In order to save time we recommend that the calculation and selection of the most suitable gas spring be completed by E. With our sophisticated selection software we can quickly determine the resultant opening or closing forces throughout the complete movement and recommend the optimum mounting points, gas spring model and nominal force. Please fax us the completed pplication ata form on page 1. E gas springs are self contained, maintenance free devices and are supplied ready for installation. The following points should be noted to ensure the longest possible working life: Gas spring force F 1: Gas springs are filled with nitrogen at very high pressures and under no circumstances should they be opened or subjected to excessive tensile loads. F H F 1 hoose a standard available gas spring from the E range featured in this catalog before determining the mounting position coordinates, or preferably allow E to do the calculations and provide a printout suggesting the most suitable model and mounting positions. External force F : for H example manual (hand) force to close the flap. Where possible arrange the mounting positions so that the effective torque provided by the gas spring positively holds the flap in its closed position. Weight force W: due to mass acting at center of gravity. Protect the piston rod from impact damage, scratches, dirt or paint contamination. The gas spring barrel must not be deformed or damaged. Gas spring orientation as desired: With piston rod downwards => damping effective at end of extension stroke. With piston rod upwards => damping effective at end of compression stroke. The gas spring must not be exposed to bending forces or side loads. If using eyelet fittings support the eye on both sides and allow some float. We recommend using ball joints on most applications as these help to eliminate any misalignment. E ontrols, Inc. Phone: Fax: shocks@acecontrols.com 4

6 Gas Spring haracteristics Gas Spring - Push Gas Spring Force - haracteristics F 4 Spring force lbs (N) F 3 compression extension F R F 2.2 F 1.2 inch (mm) Progression* approximate % Friction F R approximate lbs (N) GS (2) GS-19 GS-22 GS (3) 38 7 (3) 52 9 (4) F 1 = Nominal Force at 68 F (2 ) (this figure is normally used when specifying gas springs) F 1 to F 2 = Force on extension stroke F 3 to F 4 = Force on compression stroke *The progression (slope of the force line in the characteristic diagram above) is due to the reduction of the internal gas volume as the piston rod moves from its initial position to its fully stroked position. The approximate progression values given above for standard springs can be altered upon request. Effect of temperature: The nominal F 1 force figure is given at 68 F (2 ). n increase in temperature of F or 1 will result in approximately a 3.4% increase in the force. General extension force tolerance for fixed force gas springs is +4N/-2N. General extension force tolerance for adjustable gas springs is plus or minus 5-7%. Note: Initial breakaway force may be higher if units are stored for a long period without use. dditional Gas Spring vailable Options 1. Lockable gas springs: GF & GS 22, 28 & 4 2.
