Frequently asked questions
Common questions about RENFROE from 3G Electric.
What is the working load limit range for RENFROE plate-lifting clamps available from 3G Electric?
RENFROE plate-lifting clamps supplied by 3G Electric have working load limits ranging from 1,000 lb to 16,000 lb. For example, the LHC-00.50-A horizontal clamp is rated at 1,000 lb, while the HDR-08.00-A horizontal clamp is rated at 16,000 lb. Vertical lift clamps like the FR-03.00-A have a 6,000 lb capacity. Always select a clamp with a working load limit that exceeds the weight of the load being lifted, and account for any dynamic factors in the lift.
What attachment types are available on RENFROE clamps from 3G Electric?
RENFROE clamps offered by 3G Electric come with several attachment types: load rings, load rings with chain, and pivoting shackles. For instance, the FR-03.00-A vertical clamp uses a load ring, the SCPA-03.00-A locking clamp uses a load ring with chain, and the LPA-01.00-A locking clamp uses a pivoting shackle. The attachment type affects how the clamp connects to the hoist or crane hook, so choose based on your rigging hardware.
Can RENFROE beam clamps be used on different flange widths?
Yes, RENFROE beam clamps such as the BC-01.50-A have adjustable jaw openings. The BC-01.50-A has a minimum jaw opening of 3 inches and a maximum of 7.5 inches, allowing it to fit a range of beam flange sizes. Always measure the flange thickness and width to ensure the clamp's jaw opening range accommodates the beam. These clamps are designed for bottom mounting on beams.
Are RENFROE locking and turning clamps suitable for flipping plates during lifting?
Yes, RENFROE locking and turning clamps, such as the SCPA-03.00-A and LA-01.00-A, are designed for vertical lifts with a 180° flip capability. These clamps allow the operator to rotate the plate from vertical to horizontal or vice versa during the lift, which is useful for positioning plates in fabrication or assembly. They are manually operated and require the operator to control the flip action.
What material are RENFROE clamps made from?
All RENFROE clamps supplied by 3G Electric are constructed from steel. This material provides the strength and durability needed for lifting heavy steel plates and beams in industrial environments. The steel construction also resists deformation under load, though clamps should be inspected regularly for wear or damage. No stainless steel or aluminum options are listed in the current inventory.
How do I select the correct RENFROE clamp for horizontal versus vertical lifting?
RENFROE clamps are specifically designed for either horizontal or vertical lifting. Horizontal clamps, like the DWS-01.50-A or HDR-08.00-A, are used when the plate is lifted with its flat face parallel to the ground. Vertical clamps, like the FR-03.00-A, are used when the plate is lifted on edge. Using a clamp in the wrong orientation can cause slippage or failure. Check the product specifications for 'Lifting Orientation' to match your application.
