Rotating Equipment Rotating Equipment

In the gas turbine power plant industry bolted joints are critical on expensive rotating equipment. Thermal cycling and vibration result in settlement of flanges which can lead to gasket leaks. In worst case conditions, the power plant maintenance staff must schedule outages to tighten loose joints.

Heico-Lock® washers help avoid loosening problems. The washers are also available in Inconel and other alloys for high temperature areas. Heico-Lock® washers are especially suited for gas and steam turbines, compressors, turbochargers, pumps, mixers, motors and gearboxes.
Oil & Gas Oil & Gas

Offshore oil platforms and land based drilling equipment are exposed to high duty cycles and harsh operating conditions and/or constant vibration. Equipment such as top head drives, mud pumps and Blowout Preventers can benefit from the use of Heico-Lock® washers
Power Generation Power Generation

Securing bolted joints on gas and steam turbines is critical from a safety and reliability standpoint.
Heico-Lock® washers are suitable for fuel nozzle components, combustors and frame assemblies as well as rotors and gears with wind turbines.

Chemical Chemical

When nuts and bolts loosen in chemical plants, maintenance personnel may be exposed to dangerous chemicals and other substances. Heico-Lock washers help workers avoid unsafe conditions. Typical applications include agitation systems, mixers, stirring systems, reactors, pumps and compressors.

Rail Rail

Considered a safety related component in the rail industry, wedge-lock washers are used to secure nuts and bolts in applications such as track switches, bogies, traction motor assemblies, frogs, light rail car components etc.

Material Handling Material Handling Equipment

Cranes, forklifts, construction equipment, crushing equipment and screening equipment are associated with constant vibration that causes fasteners to loosen. Heico-Lock® washers provide a high degree of reliability.

Automotive Automotive

Headers, engine & transmission mounts, drive line components, suspension components, superchargers and turbo chargers can all benefit from the use of Heico-Lock® washers. High vibration and heat can lead to premature failure when using conventional fasteners.

Medical Equip Medical & Pharmaceutical Equipment

High productivity requires a high equipment degree of equipment reliability. Pharmaceutical equipment lines and medical equipment need bolt security.
Aerospace Aerospace

Helicopters, satellites, UAV’s and prop driven aircraft all require a high degree of reliability. Heico-Lock® is suitable for applications such as exhaust systems, props and mechanical drive systems.

Agriculture Agriculture

Combines, tractors, tillers, ploughs, etc. contain many moving parts subject to vibration. Nuts and bolts can be secured effectively with Heico-Lock® washers.

Mining Mining

Heico-Lock® washers are a superior fastening method that can avoid downtime and serviceability issues on equipment in the mining and aggregate industry. Constant vibration and high duty cycles are normally present in long wall machines, high wall machines, prep plant equipment, dragline excavators, crushing and screening equipment etc.

Military

Military

High reliability and safety are requirements for military equipment. Heico-Lock® washers are particularly suitable for artillery equipment, UAVs, personnel carriers, mine clearers and other mobile platforms.

Pulp & Paper Pulp & Paper

Nuts and bolt can loosen on shredders, debarking machines, paper roll drives and overhead cranes. Heico-Lock® washers can eliminate down time on expensive process line equipment.

Steel Production Steel Production

High duty cycle, temperature cycling and high load dynamics can create an unsafe work environment when nuts and bolts loosen. Heico-Lock® washers are suitable for transfer cars, down coilers, overhead cranes, mill stands, slitters, manipulators and other production equipment.

Electrical Electrical Appliances

Battery terminals, ring terminals, bus connections etc. are subject to vibration and thermal cycling especially on mobile equipment. Electric vehicles (EV) and hybrid vehicle technology are demanding secure connections to eliminate resistance build-up and hot spots at battery terminal connections. Due to the tension based physics of the Heico-Lock® system, clamp load is retained, eliminating loosening and possible arcing that can lead to fires and equipment failure.
