J.C. RENFROE & SONS HAS BEEN A LEADER IN THE MANUFACTURING AND MARKETING OF LIFTING PRODUCTS FOR OVER 70 YEARS.

Renfroe products are manufactured in Jacksonville, Florida and Germany. A worldwide network of stocking distributors provides a readily available source of supply and service.


We have a distinguished heritage at J.C. Renfroe & Sons. When our country has called, we have responded. The historic Liberty Bell in Philadelphia, Pennsylvania, needed to be relocated with great care. Our lifting products
were used. After the space shuttle Challenger tragedy, we were called to design a special clamp to aid in the recovery of the debris. When they needed lifting capabilities for our nuclear submarines, we were there. History
has proven when our country needed the very best, Renfroe was called.


The Renfroe legacy began in 1940 with Joseph Renfroe and his four sons. The standard of excellence on which the company was founded exists today with J.C. Renfroe II, grandson of the founder, overseeing the final
inspections of Renfroe clamps.

 

Renfroe’s innovative technology and streamlined manufacturing produces the highest quality lifting products in the industry. Our close-knit employee family continues to work with the same dedication to excellence as our founders.

NOTICE OF EXCLUSION OF WARRANTY

RENFROE HAS HEREIN SET FORTH IN CONSPICUOUS LANGUAGE AN EXCLUSION OF ANY
WARRANTY EITHER EXPRESSED OR IMPLIED, WHICH IS NOT SPECIFICALLY AND PARTICULARLY
CONTAINED HEREIN. PLEASE REFER TO THAT STATEMENT FOR REPRESENTATIONS AND
WARRANTIES OF PRODUCTS MANUFACTURED BY J.C. RENFROE & SONS.

RENFROE  202110-81M.jpg

DEFINITIONS

VERTICAL LIFT: The lifting of a single plate or member in which the lifting force exerted by the rigging is directly above and in line with the lifting shackle as shown in the
illustration below.

DEFINITIONS

VERTICAL TURN/LIFT: A vertical turn/lift clamp is a vertical lifting clamp specifically intended to turn a single plate or member thru a ninety degree (90°) arc and back to vertical thru the same ninety degree (90°) arc or from horizontal to vertical to horizontal thru a one hundred and eighty degree (180°) arc. Refer to Application Section of specific Turn/Lift clamps for further detail.


During the turning operation the edge of the plate opposite the edge to which the clamp is attached should always be in contact with a supporting surface such as a factory floor and the load on the clamp should not exceed one half rated capacity of clamp — refer to illustrations shown below.

HORIZONTAL LIFT: Clamps (used in pairs or multiples) are attached to the side edges of a plate or bundle of plates positioned horizontally to the floor level. The rigging attached to clamps is generally multi-legged slings with the connecting point of the slings being approximately centered between the distance separating the clamps. Refer to illustrations shown below.

WARNING: The capacity of all horizontal clamps is based on a sling angle of sixty degrees (60°). See illustration below. Sling angles less than sixty degrees (60°) increase the load exerted on the clamps. Sling angles greater than 60° reduce gripping force, do not exceed 60°.

STEEL PLATES: Unless otherwise specified, lifting clamps are manufactured to handle hot-rolled steel plates whose Brinell Hardness does not exceed 300.


WARNING: Do not lift plates with coatings or mill scale that prevent the gripping surfaces of the clamp from making positive contact with the base metal.


For applications not covered by the above information, secure written recommendations from RENFROE.


FINISHED AND POLISHED PLATES: Steel plates in this category having other than hot-rolled surfaces such as stainless steel, etc., are generally handled using non-marring clamps incorporating smooth gripping surfaces.


WARNING: For applications using clamps with serrated gripping surfaces on finished or polished plates, secure written recommendations from RENFROE.

STRUCTURAL MEMBERS —FABRICATED SECTIONS: Unless otherwise specified, clamps described as capable of handling structural members and fabricated sections are limited to hot-rolled steel whose Brinell Hardness does not exceed 300.

WARNING: For applications not covered by the above information, secure written recommendations from RENFROE.


RATED CAPACITY: ALL RENFROE CLAMPS
ARE RATED INDIVIDUALLY.
The rated capacity of a RENFROE product is based on the product being in “new or as new” condition and represents the maximum load the product is to be subjected to when utilized in the manner described in this manual. Wear, misuse, abuse and other factors relating to usage may reduce the rated capacity. Shock loading and the factors listed must be taken into consideration when selecting a RENFROE product for a given application.

 

PLATE THICKNESS: The minimum and maximum plate thickness a clamp specified for handling plates is

capable of lifting.

Page 78
Page 79
RENFROE  202110-82 copy.jpg

DEFINITIONS

WARNING: Never use a clamp for lifting a plate where the plate thickness is less than or greater than the minimum and maximum stenciled on the clamp.


JAW OPENING: The minimum and maximum thickness of a member of a clamp specified as having a JAW OPENING is capable of handling.


WARNING: Never use a clamp on a member whose thickness is less than or greater than the range of jaw opening stenciled on the clamp.


OPERATING TEMPERATURES: Unless specified under the Applications Section of the individual model, the approved operating temperature of RENFROE clamps is from zero degrees Fahrenheit (-18 Celsius) to a maximum of 200 degrees Fahrenheit (+93 degrees Celsius). The minimum and maximum temperatures apply to both ambient and the material being handled by the clamp.


WARNING: Secure written authorization from RENFROE before using clamps in temperatures other than shown.


“HOT LIFTS”: The Model R and S clamps are available in modifications that are capable of making lifts where the temperatures of the member being lifted exceeds 200 degrees Fahrenheit (+93 degrees Celsius). Depending on
conditions, a lift may exceed 1000 degrees Fahrenheit (538 degrees Celsius). The exact application and temperatures of the plates to be handled are critical in selecting the proper model.

 

WARNING: Secure written instructions from RENFROE for all hot lift applications.


LOCKING CLAMPS: Locking clamps are divided into the categories listed below. With the exception of the “Locking Wedge” and “Locking Screw” type the purpose of the locks are to facilitate the attaching and removing of the clamp from the member being handled.

 

“Lock Closed” — an over center spring loaded. mechanism in which the spring exerts a force on the gripping cam when the lock handle is moved to the “Lock Closed” position. When the handle is moved to unlocked position, the force exerted by the spring is relaxed and the gripping cam may be retracted by pushing the lifting shackle into the body of clamp. Refer to the Operation Section of specific models of “Lock Closed” clamps for additional details. Typical “Lock Closed” clamps are Models DG, FR, M and HRS.

 

“Lock Open Only” — normally used on “Hot Lift” clamps and consists of a manually operated “Lock Stop Pin” that is inserted when gripping cam of clamp is retracted and removed when clamp is positioned on the plate. Tag line may be used to permit operator to remove pin from a greater distance from clamp. Refer to the Operation  section of specific model of “Lock Open Only” clamps for additional details. Typical “Lock Open Only” clamp is the Model RO.

“Lock Open-Lock Closed” — an over-center spring loaded mechanism in which the spring exerts a force on the gripping cam when the lock handle is moved to the “Lock Closed” position. When the handle is moved to the “Lock Open” the gripping cam is maintained in the retracted position for ease in installing the clamp on a plate or member. The Model FRD contains individual “Lock Open” and “Lock Closed” mechanisms that must be operated separately. Refer to the Operation section of specific models of the “Lock Open-Lock Closed” clamps for additional details. Typical “Lock Open-Lock Closed”
clamps are Models FRD, R, S, SD, SEA, SX, TL, TLA and the J-Series.


“Locking Wedge” — is a fluted steel wedge that is driven in place with a hammer. The body of the wedge is positioned in a slot in the clamp body with the fluted edges contacting the member to which the clamp is being attached. Refer to Operation Section of specific models of the “Locking Wedge” clamps for additional details. Typical “Locking Wedge” clamps are Models A1, B1, B2
and PB.


“Locking Screw” — “Locking Screw” clamps depend on manually adjusting a screw to hold the gripping surface in place for lifting and removing the clamp from member being lifted. Refer to Operation Section of a specific model of “Locking Screw” clamps for additional details. Typical “Locking Screw” clamps are Models AC, ACP, BC, NM, PC, SCP, SCPA and RSC.


NON-LOCKING: “Non-Locking” clamps have no mechanisms to aid in attaching or removing clamp from member being lifted. It is necessary to have position of clamp maintained on the member being lifted until a properly applied force is exerted to the lifting shackle. Refer to Operation Section of specific models of the “Non-Locking” clamps for additional details. Typical “Non-Locking” clamps are Models AST, ASTL, BD, HR, HDR , HRS and WHSR.


WARNING: A POINTING OUT AND NOTICE OF DANGER. THE PURPOSE OF A “WARNING” IS TO APPRISE THE OPERATOR AND ALL OTHER AFFECTED PERSONS OF THE EXISTENCE OF DANGER OF WHICH HE SHOULD BE, BUT MAY NOT BE AWARE; AND TO ENABLE THE OPERATOR TO PROTECT HIMSELF AND OTHERS, WHERE APPLICABLE, AGAINST SUCH DANGER. AN ATTEMPT IS MADE HEREIN TO WARN AGAINST REASONABLE AND REASONABLY FORESEEABLE DANGER IN THE PROPER USE AND POSSIBLE REASONABLE MISUSE OF RENFROE PRODUCTS DESCRIBED IN THIS CATALOG.
