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.

VERTICAL TURN/LIFT: A vertical turn/

lift clamp is a vertical lifting clamp specifi-

cally 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 turn-

ing operation the edge of the plate oppo-

site the edge to which the clamp is at-

tached should always be in contact with

a supporting surface such as a factory

floor and the load on the clamp not ex-

ceed 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 gener-

ally multi-legged slings with the con-

necting point of the slings being ap-

proximately centered between the dis-

tance 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, Never exceed the rated ca-

pacity of a single clamp.

STEEL PLATES: Unless otherwise

specified, lifting clamps are manufac-

tured to handle hot-rolled steel plates

whose Brinell Hardness does not ex-

ceed 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 rec-

ommendations from RENFROE.

FINISHED AND POLISHED PLATES:

Steel plates in this category have other

than hot-rolled surfaces such as

stainless steel, etc., are generally han-

dled using non-marring clamps incorpo-

rating smooth gripping surfaces.

WARNING: For applications using

clamps with serrated gripping sur-

faces on finished or polished plates,

secure written recommendations

from RENFROE.

STRUCTURAL MEMBERS—

FABRICATED SECTIONS: Unless

otherwise specified, clamps described

as capable of handling structural mem-

bers and fabricated sections are limited

to hot-rolled steel whose Brinell Hard-

ness does not exceed 300. WARNING:

For applications not covered by the

above information, secure written

recommendations from RENFROE.

RATED CAPACITY: The rated capacity

of a RENFROE product is based on the

product being in “new or as new” condi-

tion 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 re-

duce the rated capacity. Shock loading

and the factors listed must be taken into

consideration when selecting a

RENFROE product for a given applica-

tion.

PLATE THICKNESS: The minimum

and maximum plate thickness a clamp

specified for handling plates is capable

of lifting. WARNING: Never use a

clamp for lifting a plate where the

plate thickness is less than or

greater than the minimum and maxi-

mum stenciled on the clamp.

JAW OPENING: The minimum and

maximum thickness of a member of

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 clamp.

OPERATING TEMPERATURES:

Unless specified under the Application

Section of the individual model, the ap-

proved operating temperature of

RENFROE clamps is from zero degrees

Fahrenheit (-18 Celsius) to a maximum

of 200 degrees Fahrenheit (+93 de-

grees 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 de-

grees Fahrenheit (538 degrees Cel-

sius). The exact application and tem-

peratures 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 han-

dled.

“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 re-

laxed and the gripping cam may be re-

tracted by pushing the lifting shackle

into body of clamp. Refer to the Opera-

tion Section of specific models of “Lock

Closed” clamps for additional details.

Typical “Lock Closed” clamps are Mod-

els DG, FR and M.

“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 spe-

cific 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 install-

ing the clamp on a plate or member.

The Model FRD contains individual

“Lock Open” and “Lock Closed” mecha-

nisms that must be operated separately.

Refer to the Operation Section of spe-

cific 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

Model A1, B1, B2 and PB.

”Locking Screw” - “Lock 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, NM, PC, SCP and

SCPA.

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 Model AST, ASTL, BD, HR, HDR

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 oth-

ers where applicable against such dan-

ger. 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

manual.

DESIGNATED PERSON — A person se-

lected by the employer or the employer’s

representative as being competent to per-

form those specific duties.

QUALIFIED PERSON — A person who, by

possession of a recognized degree in an

applicable field or certificate of professional

standing, or who, by extensive knowledge,

training, and experience, has successfully

demonstrated the ability to solve problems

relating to the subject matter at hand.
