
Normal Service – equipment in place - yearly
Heavy Service – equipment in place - yearly
Severe Service – equipment in place - quarterly
Hoist Maintenance
Procedures
Lubrication
Hose and Connections
Check
oil daily and maintain proper levels
Secure drain plugs and vent cap
Drain oil regularly and replace
Water will accumulate and cause blow-by
Use
Gear Lubrication
Mounting
be done every 60 – 90 days
Inspect gear end for sufficient signs of
lubrication
Add No. 1 grade gear grease to the grease
plug
Mount
Should
proper air hose connections and hose
safety clamp -1” crowfoot with safety clamp
Smaller hose and fittings will reduce
efficiency of the winch
For top performance operate winch at 90
psig (6.2 bar/620 kPa) air pressure
drum so that the axis of drum is
horizontal and vent cap is not more than 15
degrees off of top vertical
Check mounting bolts and base plate before
executing a lift

Review the troubleshooting guide on common winch
symptoms , probable causes and remedies
Check all air hoses connections and do a pre-start
inspection on the power source (air compressor)
Make sure air supply is clean and free from moisture
Check air hoist position and mounting to surface
before use
Conduct a detail inspection all components (brake
lining and handle) and moving parts on hoist before
using hoist.
Make sure at least 3 wraps of wire are on the drum
before use and never have less than three wraps at all
times
Inspect wire and verify wire rope diameter to match
load
Make sure PPE is worn during operations
CAUTION –
Never perform maintenance while the
hoist is under a load. Disconnect
all air lines and tag before
maintenance. Air exhaust from the
motor can cause debris to fly.

Never lift a load of unknown weight or weight
greater than winch capacity
Never use winch rope as a sling
Always stand clear of load and never carry
load over people
Insure clutch is fully engaged and do not
disengage clutch with load
Do not “side pull” or “yard” hoist
Do not operate with kinked, twisted, or
damaged wire
Make sure wire winds properly on drum
Standard Formula is 20 times winch diameter
for self winding
Ease slack out of wire when starting a lift. Do
not jerk or yank the load
Be sure no objects are in the way of load
Always test winch to MAX capacity with dead
pull to check rigging and winch mount tie
downs
Avoid shock loads
Any product will break if abused, misused,
overused, or not maintained properly

Do not use winch as a ground for welding or
attach a welding electrode to winch or sling
Do not leave load suspended for an extended
period of time-never unattended
Always check brake and lubrication before lift
Never - ever do anything you believe to be
unsafe
Do not swing a suspended load
If communication is lost with the operator
“All Stop”
If unsure of directions given, “ All Stop”
Operator can “STOP” lift at anytime if he feels
that it is unsafe
Attachments must have the same working

Wire Rope Spooling
Criteria
–
–
–
–
–
–
–
When reeling wire rope from one reel to another, it is preferable for
the rope to travel from top to top
Hoist should be spooled with the recommended wire rope size.
Ensure tension is applied to wire rope when spooling onto drum
(approximately 10% of working load is recommended.
Cutting and seizing wire rope – should be properly seized on both
sides of the cut, if not wire will unravel. Use proper PPE when
working with wire
Do not install wire that has been overloaded or stretched
Make sure wire is properly attached to the drum with the set screws.
Wire rope anchors are not intended to retain the full load. Ensure
three wraps of wire are always on the drum. Less than three wraps
will allow rope anchors to loosen.
Keep tension on the wire while spooling on drum and guide each
wire close to the preceding wrap
After installation, allow wire to run through a cycle of operation at low
speed
ANSI ASME B 30.9
Safety Code

Section 9-2.1: Construction
9-2.1.1 Wire Rope Material
The wire rope slings covered by this Chapter shall be as specified in
Tables 4 through 11 based upon nominal wire rope strength as shown
in Federal Specification RR-W-410 and Military Specification MIL-W83420 (except for fatigue requirements which are not applicable to
sling usage). Grades, types, sizes, and constructions other than those
specified in Tables 4 through 11 may be used. When such slings are
used, the sling manufacturer shall be consulted for specific data.
9-2.1.2 Minimum Sling Length
(a) Slings made of rope with 6 x 19 and 6 x 37 classification, and cable
laid slings shall have a minimum clear length of rope 10 times the rope
diameter between splices, sleeves, or end fittings.
(b) Braided slings shall have a minimum clear length of rope 40 times
the component (individual) rope diameter between the loops or end
fittings.
(c) Grommets and endless slings shall have a minimum circumferential
length of 96 times the body diameter of the grommet or endless sling.
9-2.4.1 All swaged-socket and poured-socket assemblies shall be
proof tested to the wire rope or fitting manufacturers recommendations
but in no case greater than 50% of the component wire ropes' or
structural strands' nominal strength. All other assemblies shall be proof
tested when specified by the purchaser. The proof load for swagedsocket and poured-socket assemblies shall be a minimum of two times
the vertical hitch rated load but shall not exceed 2.5 times the vertical
hitch rated load.
9-2.4.2 The proof load for single leg hand tucked slings shall be a
minimum of the vertical hitch rated load and shall not exceed 1.25
times the vertical hitch rated load.
9-2.4.3 The proof load for mechanical splice single leg slings and
endless slings shall be two times the vertical hitch rated load.
9-2.4.4 The proof load for multiple leg bridle slings shall be applied to
the individual legs and shall be either 1.25, for hand tucked splice, or
2, for mechanical splice, times the vertical
hitch rated load of a single leg sling of the same size, grade, and
construction of rope. Any master link to which multiple leg slings are
connected shall be proof loaded to two times the force applied by the
combined legs.
ANSI ASME B 30.9 Safety
Code
Section 9-2.5: Sling Identification
9-2.5.1 Marking Requirements. Each sling shall be marked to show:
(a) name or trademark of manufacturer,
(b) rated load for the type of hitch(es), and the angle upon which it is based,
(c) diameter or size
9-2.5.2 Sling identification shall be done by the sling manufacturer.
9-2.5.3 Maintenance of Sling Identification.
Sling identification should be maintained by the user so as to be legible during the life of the sling.
Section 9-2.6: Effects of Environment
9-2.6.1 Fiber core wire rope slings of all grades shall not be exposed to temperatures in excess of 180 °F (82°C).
9-2.6.2 When wire rope slings of any grade are to be used at temperatures above 400°F (204°C) or below -60 °F ( -51°C),
the sling manufacturer should be consulted.
9-2.6.3 The strength of slings can be affected by chemically active environments as sling materials may be susceptible
to damage from caustic or acid substances or fumes; strongly oxidizing environments attack all common sling
materials. The sling manufacturer should therefore be consulted before slings are used in chemically active
environments.
Section 9-2.7: End Attachments
9-2.7.1 All load bearing components welded prior to or after assembly in the sling shall be proof tested.
9-2.7.2 Welding of handles or any other accessories to end attachments, except covers to thimbles, shall be performed
prior to the assembly of the sling.
9-2.7.3 Knots. Eyes in wire rope slings shall not be formed using knots.
9-2.7.4 Wire Rope Clips and Hooks
9-2.7.4.1 Wire rope clips shall not be used to fabricate wire rope slings except where the application of slings prevents
the use of prefabricated slings or where the specific application is designed by a qualified person.
9-2.7.4.2 Slings made with wire rope clips should not be used as a choker hitch.
9-2.7.4.3 Wire rope clips shall be drop-forged steel of the single saddle (U-bolt) or double saddle type clip. Malleable cast
iron clips shall not be used. For spacing, number of clips, and torque values, refer to the clip manufacturer's
recommendation.
Air Hose - Safe Practices



All hose assemblies should be viewed as potential hazards. This document is designed to inform and educate anyone who
manufactures, specifies, supplies, purchases, assembles, uses, maintains or tests any hose assemblies or its component parts. The
proper selection and maintenance of hose, couplings, attachment devices and accessories are imperative.
It is the end users responsibility to identify to the distributor the application and any special conditions that the hose assembly must
meet. It is the distributors responsibility to supply the proper assembly for the intended application. Accidents and down time may
occur if hose assemblies are not properly selected for the specific application.
The performance and safety of the assembly is affected by the quality of the individual components. The use of the acronym
S.T.A.M.P.E.D. (Size, Temperature, Application, Media, Pressure, Ends) will help in the proper selection of the hose assembly
components.
Failure to use these procedures can result in serious injury and destruction of property and
equipment.
When fabricating and specifying hose assemblies ask the following questions:






Size: What is the I.D. (Inside Diameter) of the hose? What is the O.D. (Outside Diameter) of both ends of the hose? What is the
overall length of the assembly required?
Temperature: What is the temperature range of the media (product) that is flowing through the hose assembly? What is the
temperature range of the environment that surrounds the outside of the hose assembly?
Application: How is the hose assembly actually being used? Is it a pressure application? Is it a vacuum (suction) application? Is it a
gravity flow application? Are there any special requirements that the hose assembly is expected to perform? Is the hose being used
in a horizontal or vertical position? Are there any pulsations or vibrations acting on the hose assembly?
Media: What is the media/material that is flowing through the hose assembly? Being specific is critical. Check for: Abrasive
materials, chemical compatibility, etc.
Pressure: What is the maximum pressure including surges (or, maximum vacuum) that this hose assembly will be subjected to?
Always rate the maximum working pressure of your hose assembly by the lowest rated component in the system.
Ends: What couplings have been requested by the user? Are they the proper fittings for the application and hose selected?
Hose assemblies must be inspected prior to each use. Worn out fittings, attachment devices, hose
and accessory items must be replaced. Retaining devices (safety devices) such as clips, cables or
chains must be used. Clamps must be checked regularly to the specified torque found in the Dixon
literature. Under no circumstance should any coupling be disconnected while under pressure unless
the coupling is specifically designed to do so. Disconnecting couplings under pressure could result
in serious injury or death, and destruction to property and equipment.
Air Hose
Safe Practices










Before attempting to disconnect the hose from the air line, the air should be cut off. Store hose
coils off the floor promptly after use. A safety-check valve installed in the air line at the
manifold will stop the air supply automatically if a line break occurs. A short chain fastened to
the hose and to the tool housing can keep the hose from thrashing about if a coupling breaks
Check to be sure the air hose is in good condition. Air hoses are designed to withstand
pressure, but they become weakened at points where they have been bent, where they are
attached to the shutoff valve and to the nozzle, and where they have been kinked. These
weak points may swell like a balloon and burst, throwing pieces of hose in every direction.
Always coiling the hose without kinks -- and hanging it over a broad support, not over a hook,
nail, or angle iron when it is not in use.
Air hoses
An air hose presents the same tripping or stumbling hazard as cords on electric tools. Persons
or materials accidentally hitting the hose may unbalance the operator or cause the tool to fall
from an overhead place;
Air hoses should be protected from trucks and pedestrians by runways or planks laid on either
side of the hose;
