Welcome to Advance Welding Service, Inc.

While working onsite in hoistways it was apparent there was a safety risk present regarding lifting devices used for the removal and/or installation of cylinder and/or piston assemblies. The majority of elevator companies across the country still use non-rated wooden clamps and metal wrenches for lifting which can fail without warning causing injury.

We have designed, rated and patented a unique line of clamps specifically for lifting, landing, loosening and tightening of cylinder/piston assemblies to make a safer workplace. In addition to lifting clamps we now offer the Omega Rail Lifting System, made exclusively for omega rails. Patented design and safety rated to safely suspend car and hoisting procedures. All products are exclusively manufactured in the USA by Advance Welding Service Inc.
