General Clamp Industries, Inc. is one of a group of companies active in the lifting industry since 1965. We have over 40 years of successful service in the lifting and material handling industry. Beginning in 1965 as an inspection contractor, we quickly grew until today, where we are one of three related companies, all active in the lifting field.

General Clamp Industries, Inc. manufactures SuperClamp™ beam and girder clamps and trolleys. This unique line of patented under-hook lifting accessories is designed around safety and ease of use. SuperClamp™ incorporates a left- and right-hand threaded adjustment bar for fast installation and removal. The design ensures that each clamp need be hand-tightened only — no tools required. General Clamp Industries also manufactures the only American-made, fully-adjustable, one piece beam trolley. The SuperClamp™ A, B, and BA series of trolleys requires no tools or spacers to be safely installed on the beam flange. Many of our standard clamp and trolley models are approved for personnel use as Personal Fall Arrest System (PFAS) anchorage points.

General Clamp Industries, Inc. is conscious of its responsibility to industry and workers, and we ensure that all engineering, design and manufacture is carried out to exacting quality standards and in strict accordance with all regulations. SuperClamp™ products are certified to meet or exceed all existing state and federal codes, and each unit is load-tested prior to shipping. Our sister companies, United States Crane, Inc. and United States Crane Certification Bureau, Inc. are also directly involved in the lifting and hoisting industry.

United States Crane, Inc. manufactures a line of Personnel Lifting Platforms under the trade name SuperCage™.  SuperCage™ is available in four basic configurations: as a Suspended Platform; as a Direct Fixed Attachment Platform; as a ForkLift Platform; and as a Non-Personnel Platform.  United States Crane, Inc. also specializes in the design, manufacture and rebuilding of mobile and tower cranes and derrick booms.  With over 40 years of experience in this field and a corporate mission for quailty and safety, United States Crane is the leader in this field.
