Safety Summary
WARNING
•Pullersaredesignedtoprovidea4to1safetyfactorandare
factory tested to 125% of the rated load. The supporting
structures and load-attaching devices used in conjunction with
this puller must provide adequate support to handle all puller
operations, plus the weight of the puller and attached
equipment. This is the customer’s responsibility. If in doubt,
consult a registered structural engineer.
Ingersoll-Rand pullers are manufactured in accordance with the
latest ASME B30.21 standards.
The National Safety Council, Accident Prevention Manual for
Industrial Operations, Eighth Edition and other recognized safety
sources make a common point: Employees who work near cranes
or assist in hooking on or arranging a load should be instructed to
keep out from under the load. From a safety standpoint, one factor
is paramount: conduct all lifting or pulling operations in such a
manner that if there were an equipment failure, no personnel
would be injured. This means keep out from under a raised load
and keep out of the line of force of any load.
The Occupational Safety and Health Act of 1970 generally places
the burden of compliance with the user, not the manufacturer.
Many OSHA requirements are not concerned or connected with
the manufactured product but are, rather, connected with the final
installation. It is the owner’s and user’s responsibility to determine
the suitability of a product for any particular use. It is
recommended that all applicable industry, trade association,
federal, state and local regulations be checked. Read all operating
instructions and warnings before operation.
Rigging: It is the responsibility of the operator to exercise caution,
use common sense and be familiar with proper rigging techniques.
Refer to ASME B30.9 for rigging information, American National
Standards Institute, 1430 Broadway, New York, NY 10018.

INSPECTION
There are two types of inspection, frequent inspection performed
by operator and more thorough periodic inspections performed by
personnel trained in operation and repair of this puller. Careful
inspection on a regular basis will reveal potentially dangerous
conditions while still in early stages, allowing corrective action to
be taken before condition becomes dangerous. Any deficiency
revealed through inspection must be corrected before resuming
operation of the puller. A determination must be made as to
whether a deficiency constitutes a safety hazard.
Frequent Inspection
The ratchet puller should be inspected prior to each use. Visual
observations should be conducted during regular operation for any
evidence of damage or malfunction.
1. OPERATION. Check for visual signs or abnormal noises
which could indicate a potential problem. Ensure handle
mechanism, driving dog and holding dog function properly.
Repair or replace if damaged.
2. HOOKS. Check for wear or damage, increase throat width,
bent shank or twisting of hook. Replace hooks which exceed
throat opening discard width specified in Table 2 (refer to
Dwg. MHP0040 on page 5) or exceed a 10° twist (refer to

Periodic Inspection
According to ASME B30.21, frequency of periodic inspection
depends on the severity of usage:
Disassembly may be required for HEAVY or SEVERE usage.
Keep accumulative records of periodic inspections to provide a
basis for continuing evaluation. Inspect all items in “Frequent
Inspection”. Also inspect the following:
1. FASTENERS. Check rivets, capscrews, nuts, cotter pins, and
other fasteners on hooks and puller frame. Replace if missing
and tighten or secure if loose.
2. ALL COMPONENTS. Inspect for wear, damage, distortion
and cleanliness. If external evidence indicates the need,
disassemble. Check teeth, frame, shafts, drum, sheaves,
guides, springs and covers. Replace worn or damaged parts.
Clean, lubricate and reassemble.
3. HOOKS. Inspect hooks for cracks. Use magnetic particle or
dye penetrant to check for cracks. Inspect hook retaining
parts. Tighten, repair or replace if necessary. Refer to latest
edition of ASME B30.10 (Hooks) for additional hook
inspection information.
4. DRUM AND SHEAVES. Check for excessive wear or
damage. Replace if necessary.
5. DOG MECHANISMS. Check dogs engage drum teeth.
Check holding dog pawl, driving dog pawl and drum teeth for
cracks, wear or damage. Check springs for distortion or
damage. Repair or replace parts as necessary.
6. LABELS. Check for presence and legibility. Replace if
necessary.
7. WIRE ROPE. Besides the items in a frequent inspection,
inspect for the following:
a. Build-up of dirt and corrosion. Clean if necessary.
b. Loose or damaged end connection. Replace if loose or
damaged.
c. Check wire rope anchor is secure.
d. Changes in size of the wire rope diameter. Periodically
measure diameter of wire rope from crown-to-crown
throughout life of wire rope. The actual diameter should
be recorded when wire rope is under equivalent loading
and in the same operating section. If actual diameter of
wire rope has decreased more than 1/64 in. (0.4 mm) a
thorough examination of wire rope should be conducted
by an experienced inspector to determine the suitability
of wire rope to remain in service. Refer to Dwg.

Resumen de Seguridad
WARNING
• Los elevadores-tensores están diseñados para proporcionar
unfactordeseguridadde4a1ysehanprobadoenlafábrica
al 125% de la carga nominal. Las estructuras de apoyo y los
dispositivos para agregar carga que se usan junto con estos
elevadores-tensores deben proporcionar un apoyo adecuado
para soportar todas las operaciones del elevador-tensor
además del peso del elevador-tensor y del equipo agregado.
Esto es responsabilidad del cliente. En caso de duda, consulte a
un ingeniero en estructuras profesional.
Los elevadores-tensores Ingersoll-Rand están hechos de acuerdo
con las normas ASME B30.21 más recientes.
En la octava edición del Manual de Prevención de Accidentes para
Operaciones Industriales del Consejo Nacional de Seguridad
(EE.UU.), y en otras fuentes de seguridad reconocidas, se
establece un punto común: se debe instruir a los empleados que
trabajan cerca de las grúas o que ayudan a enganchar o arreglar la
carga a que se mantengan alejados del área debajo de la carga.
Desde el punto de vista de la seguridad, hay un factor de suma
importancia: se debe llevar a cabo toda operación de elevación o
de tiro de manera que si ocurriera una falla en el equipo, ninguna
persona resultaría lesionada. Esto significa mantenerse alejado del
área debajo de toda carga elevada y de la línea de fuerza de toda
carga.
La Ley de Seguridad y Salud Laboral (OSHA) de 1970
generalmente coloca la responsabilidad por el cumplimiento de las
normas en el usuario, no en el fabricante. Muchos requisitos
OSHA no se refieren al producto fabricado sino, más bien, a la
instalación definitiva. Es responsabilidad del propietario y del
usuario determinar la adecuación de un producto a un uso en
particular. Se recomienda que se revisen todas las regulaciones
federales, estatales y locales, así como aquellas de la industria y de
las asociaciones comerciales. Lea todas las instrucciones y
advertencias operativas antes de su operación.
Montaje: Es responsabilidad del operador ejercer precaución,
usar el sentido común y familiarizarse con las debidas técnicas de
montaje. Refiérase a las normas ASME B30.9 para obtener
información con respecto al montaje, American National
Standards Institute, 1430 Broadway, New York, NY 10018.

INSPECCIÓN
Hay dos tipos de inspección, la inspección frecuente que lleva a
cabo un operador y las inspecciones más minuciosas que realiza el
personal capacitado en la operación y la reparación de este
elevador-tensor. La inspección cuidadosa realizada con
regularidad revelará las condiciones potencialmente peligrosas
durante la etapa inicial, permitiendo que se adopten acciones
correctivas antes de que la condición se vuelva peligrosa. Todas
las deficiencias reveladas mediante la inspección se deben corregir
antes de reanudar la operación del elevador-tensor. Se debe
determinar si la deficiencia constituye un riesgo de seguridad.
Inspección Frecuente
El elevador-tensor de trinquete debe ser inspeccionado antes de
cada uso. Deben llevarse a cabo inspecciones visuales durante la
operación regular para ver si hay daño alguno o evidencia de
desperfectos.
1. OPERACIÓN. Revise para ver si hay señales visuales o
ruidos fuera de lo normal que pudieran indicar un problema
potencial. Asegúrese de que el mecanismo de la manivela, la
garra de arrastre y la garra de retención funcionen
debidamente. Haga reparaciones o cambios si están dañados.
2. GANCHOS. Inspeccione para ver si hay desgaste o daños,
aumento en el ancho de garganta, el vástago está doblado o
hay una dobladura en el gancho. Reemplace los ganchos que
exceden la anchura de descarte especificada en la Tabla 2
(refiérase al Dibujo MHP0040E en la página E-5) o excedan
un torcimiento de 10° (refiérase al Dibujo MHP0111E en la
página E-5). Si al encajar el pestillo del gancho éste pasa de
la punta del gancho, el gancho está vencido y debe
cambiarse.

3. PESTILLOS DE LOS GANCHOS. Revise el funcionamiento
del pestillo del gancho. Cámbielo si está roto o instálelo si no
está presente.
4. CABLE METÁLICO. Lubríquelo si es necesario. Cámbielo
si está dañado o excesivamente desgastado. Consulte la
información de inspección del fabricante del cable metálico o
de una fuente de seguridad de reconocido prestigio, tal como
la más reciente edición del Manual de Prevención de
Accidentes para Operaciones Industriales del Consejo
Nacional de Seguridad (EE.UU.), o las normas ASME
B30.21. La siguiente lista es una guía para el usuario acerca
de las normas aceptadas en función de las cuales se debe
juzgar el cable metálico, y las cuales no se presentan con la
intención de substituir a un inspector experimentado.
a. Daños tales como el abombamiento del cable, los
retorcimientos, las protuberancias del alma, el
aplastamiento, los daños térmicos y el desplazamiento
del cabo principal.
b. Corrosión y melladuras.
c. Desgaste de los alambres en los extremos del diámetro
exterior. Reemplácelo si el desgaste es de 1/3 del
diámetro original de un alambre en el extremo del
diámetro exterior.
d. Alambres o cabos rotos, en especial en las conexiones.
Es necesario reemplazarlo si hay un alambre roto en una
conexión; doce alambres rotos en un paso; o cuatro
alambres rotos en un cabo en un paso.
5. CORREA SINTÉTICA. La correa debe estar limpia y seca.
Quite todo lubricante o suciedad. Reemplace la correa si está
deshilachada o cortada.
6. LABOREO DEL CABLE METÁLICO O DE LA CORREA.
Revise el laboreo y asegúrese de que el cable metálico o la
correa estén debidamente asegurados en el tambor. Consulte

otros daños. Reemplácela si es necesario.
Inspección Periódica
Según las normas ASME B30.21, la frecuencia de la inspección
periódica depende de la exigencia del uso:
Es posible que sea necesario desarmar la unidad para los usos
PESADO o EXIGENTE. Mantenga un registro acumulativo de las
inspecciones periódicas para proporcionar una base de evaluación
continua. Inspeccione todos los elementos que se indican en la
sección “Inspección frecuente”. Inspeccione también lo siguiente:
1. ELEMENTOS DE SUJECIÓN. Revise los remaches, los
tornillos de cabeza, las tuercas, los pasadores y los otros
elementos de sujeción en los ganchos y en el bastidor del
elevador-tensor. Instálelos si faltan y apriételos o afiáncelos si
están flojos.
2. TODOS LOS COMPONENTES. Inspeccione para ver si hay
desgaste, daños o deformación y para ver si están limpios.
Desarme la unidad si la apariencia exterior así lo indica.
Revise los bastidores, los ejes, el tambor, las roldanas, las
guías, los resortes y las tapas. Reemplace las piezas
desgastadas o dañadas. Limpie, lubrique y vuelva a armar la
unidad.
3. GANCHOS. Inspeccione los ganchos para ver si hay fisuras.
Use un penetrante colorante o de partículas magnéticas para
revisar si hay fisuras. Inspeccione las piezas de retención del
gancho. Apriételas, repárelas o cámbielas si es necesario.
Refiérase a la más reciente edición de las normas ASME
B30.10 (Ganchos) para obtener información adicional acerca
de la inspección de los ganchos.
4. TAMBOR Y ROLDANAS. Revise para ver si hay desgaste o
daño excesivo. Reemplácelos si es necesario.
5. MECANISMOS DE LAS GARRAS. Revise que las garras se
acoplen con los dientes del tambor. Revise la uña de la garra
de retención, la uña de la garra de arrastre y los dientes del
tambor para ver si hay fisuras, desgaste o daño. Revise los
resortes para ver si hay distorsión o daño. Repare o reemplace
las piezas según sea necesario.
6. RÓTULOS. Revise que estén presentes y sean legibles.
Reemplácelos si es necesario.
7. CABLE METÁLICO. Además de los elementos indicados en
una inspección frecuente, inspeccione lo siguiente:
a. Acumulación de suciedad y corrosión. Limpie si es
necesario.
b. Conexiones flojas o dañadas en los extremos.
Reemplácelas si están flojas o dañadas.
c. Revise que el anclaje del cable metálico esté firme.
d. Cambios en el tamaño del diámetro del cable metálico.
Mida periódicamente el diámetro máximo del cable
metálico durante su vida útil. El diámetro real debe
registrarse cuando el cable metálico esté bajo cargas
equivalentes y en la misma sección de operación. Si el
diámetro real del cable metálico se ha reducido más de
1/64 de pulg. (0.4 mm), un inspector experimentado
