The Renfroe 3 Ton Locking Screw Type Clamp is a manually secured lifting clamp designed for heavy-duty applications requiring a positive mechanical lock to maintain clamping force throughout the lifting, transport, or positioning operation. The locking screw mechanism allows the operator to set the jaw opening precisely to the material thickness, apply controlled clamping force, and secure the lock before the lift begins, providing a reliable and adjustable grip that is maintained independent of load direction or magnitude. This positive retention design makes the locking screw type clamp well suited for horizontal transport, tilting, and other non-vertical lifting orientations where a self-tightening cam-action clamp may not provide adequate security for the intended application.
Rated at 3 Ton working load limit, this clamp is designed for handling heavier flat steel plate and structural members in demanding industrial environments including steel mills, heavy fabrication shops, and plate processing facilities. At this capacity, the locking screw mechanism provides the positive jaw retention needed to handle heavier material safely across a range of lifting orientations and rigging configurations, including applications where the load direction may change during the operation or where the rigging may go slack at any point in the lift cycle. The adjustable jaw opening accommodates a range of plate thicknesses within the clamp's rated jaw opening range, providing versatility across varied material dimensions.
Renfroe locking screw type clamps are built to the quality and durability standards that define the Renfroe product line, with robust alloy steel construction designed to withstand the demands of repeated heavy industrial use. Proper clamp selection based on material thickness within the rated jaw opening range, surface condition, and total load weight, combined with thorough pre-use inspection of the locking screw, jaw, and body, is essential to safe and reliable performance in every application.
Material: Alloy steel
Uses: Lifting and positioning of heavier flat steel plate and structural material Horizontal transport and tilting applications Applications requiring positive mechanical lock independent of load direction Steel mill and heavy fabrication shop plate handling Situations where load orientation or rigging configuration requires a positively locked clamp at higher capacities
Key Features: 3 Ton working load limit Locking screw mechanism provides positive, adjustable clamping force Secure grip maintained independent of load direction or magnitude Suitable for non-vertical lifting orientations where cam-action clamps are not appropriate Adjustable jaw opening to accommodate varying material thicknesses Robust alloy steel construction for repeated heavy industrial use
Note: Always verify material thickness is within the clamp's rated jaw opening range before use. Do not exceed the 3 Ton working load limit. Inspect the locking screw, jaw, and body before each use. Use only in applications and orientations for which this clamp type is designed and rated.
