RENFROE

RENFROE is a manufacturer of lifting and material handling equipment, with a product line that includes plate lifting clamps, beam clamps, and locking clamps. The company's history in the lifting industry dates back to the mid-20th century, and its products are used in industrial settings where secure load attachment and controlled movement are required. The clamps are typically constructed from steel and are designed for manual operation, with working load limits that range from 1,000 lb to 12,000 lb in the plate clamp family alone. Attachment types include pivoting shackles, load rings, and load rings with chain, allowing adaptation to different rigging configurations. Many models support vertical lift with a 180-degree flip, enabling the operator to rotate a plate from horizontal to vertical or vice versa without repositioning the clamp. This function is useful in fabrication, welding, and assembly operations where plate steel must be turned for access to both sides or for alignment with other components. The clamps are intended for use with overhead lifting equipment such as hoists and cranes, and they incorporate locking mechanisms to maintain grip on the load. 3G Electric supplies RENFROE lifting clamps as part of its industrial equipment catalog, serving plant engineers, maintenance managers, and procurement specialists who need to specify or replace lifting hardware. The product range available through 3G Electric includes multiple plate clamp models with different working load limits and attachment options, allowing selection based on the weight and dimensions of the material being handled. Because these are safety-critical components, buyers should verify that the working load limit and attachment type match the intended lift, and that the clamp is compatible with the rigging and lifting device in use. 3G Electric provides product specifications, manufacturer part numbers, and logistics support for global delivery, but does not provide engineering certification or load testing services. For application-specific guidance, consult the manufacturer's documentation or a qualified engineer. The RENFROE line is one of several lifting and rigging product families offered by 3G Electric, which also includes industrial burners, pumps, and gas controls. This breadth allows procurement to consolidate orders for multiple equipment categories, though technical requirements for each product family should be evaluated separately. When ordering RENFROE clamps, confirm the model number, working load limit, and attachment type against the lift plan. Spare parts and replacement units are available through 3G Electric's catalog, subject to manufacturer availability. The information provided here is based on publicly available product data and is intended for technical reference only.

Frequently asked questions

Common questions about RENFROE from 3G Electric.

What is the working load limit range for RENFROE plate lifting clamps?

RENFROE plate lifting clamps available through 3G Electric have working load limits from 1,000 lb to 12,000 lb. Specific models include the JPA-00.50-A at 1,000 lb, JPA-01.00-A at 2,000 lb, JPA-02.00-A at 4,000 lb, LPA-03.00-A at 6,000 lb, and TLA-06.00-A at 12,000 lb. The working load limit is marked on the clamp and must not be exceeded. When selecting a clamp, consider the weight of the plate, the number of clamps used, and the lift angle, as these factors affect the effective load on each clamp. Always follow the manufacturer's instructions for safe operation.

What is the difference between a pivoting shackle and a load ring attachment on RENFROE clamps?

The attachment type determines how the clamp connects to the lifting device. A pivoting shackle attachment allows the shackle to rotate, which can accommodate some misalignment between the clamp and the lifting hook or sling. A load ring attachment provides a fixed ring for connecting hooks or shackles. Some RENFROE models, such as the SCPA-03.00-A, feature a load ring with chain, which may offer additional flexibility in rigging. The choice depends on the rigging configuration and the need for articulation. Both types are used in vertical lift applications with 180-degree flip capability. Verify compatibility with your existing hooks and slings before ordering.

Can RENFROE plate clamps be used to flip a steel plate 180 degrees?

Yes, many RENFROE plate lifting clamps are designed for vertical lift with a 180-degree flip. This allows the operator to lift a plate and rotate it from horizontal to vertical or vice versa. The flip is manually controlled, and the clamp must be locked onto the plate before lifting. This feature is useful in fabrication and welding when both sides of a plate need to be accessed. However, the flip operation should only be performed when the load is stable and the area is clear. Always follow the manufacturer's operating instructions and ensure the clamp is rated for the load and the specific motion.

What materials are RENFROE lifting clamps made from?

RENFROE lifting clamps in the 3G Electric catalog are constructed from steel. Steel is used for its strength and durability in industrial lifting applications. The clamps may have components such as shackles, load rings, and chains that are also steel or alloy steel. The specific grade of steel is not listed in the product data, but the working load limits indicate the capacity of the clamp. Regular inspection for wear, deformation, or corrosion is recommended, and any clamp showing signs of damage should be removed from service. Consult the manufacturer's literature for material specifications and inspection criteria.

How do I select the correct RENFROE plate clamp for my application?

Selection depends on the plate weight, thickness, and the lift method. Determine the total load to be lifted, then choose a clamp with a working load limit that exceeds that load, accounting for the number of clamps and the lift angle. Consider the attachment type: pivoting shackle for some articulation, load ring for a fixed connection, or load ring with chain for additional rigging options. Verify the clamp's jaw opening matches the plate thickness. The 180-degree flip capability is useful if you need to rotate the plate. Always follow the manufacturer's application guidelines and ensure the clamp is compatible with your lifting equipment. When in doubt, consult a qualified engineer.
