2. INTRODUCTION to WINCH APPLICATIONS
Congratulations on your purchase of a Best Safety Systems Pro-Series Man-Rated Winch as part of your
safety at heights equipment.
Pro-Series winches combine many advanced safety features, including multiple brake pawls, a secondary
inertia actuated brake, easy to read visual brake wear indicator, visual overload indicator integral to the
snap hook, and optional usage indicator.
Some versions of these winches feature a unique drive input hub design which allows the winch to be
easily switched from a manual crank to various power drive options to allow the winch to be driven with
different types of corded and cordless power hand drills (See Section 6 for further information on Power
Drive options).
The winch may be equipped with a variety of winch line options including, stainless or galvanized steel
cable in various diameters, and ropes in various diameters and constructions to meet your specific job
requirements.
This product has been specifically designed and carefully manufactured to provide reliable operation in
many different safety-at-heights applications. These include, but are not limited to:
2.1 WORK POSITIONING
The winch may be used for the suspension of a worker at a work position for the performance of a task.
When a worker is suspended in a work seat or harness, a secondary personal fall arrest system must be
used in addition to the suspension line. Personal fall arrest systems used with this winch must meet
applicable OSHA or other local requirements.
NOTE: OSHA 29 CFR 1926 Subpart L considers this application to be a single point suspension scaffold,
and requires treatment as such.
2.2 RESCUE
The winch may be used as part of a system to allow for the post-fall rescue of a worker protected by a
personal fall arrest system. This winch meets the requirements of ANSI/ASSE Z359.4 for use as a
rescue device.
2.3 CONFINED SPACE ENTRY / RETRIEVAL and RESCUE
The winch may be used as part of a system to facilitate access to and egress from a confined space as
well as non-entry rescue in the event of an emergency. This winch meets the requirements of OSHA
1910.146, and ANSI/ASSE Z117.1 for use as a confined space entry/retrieval and rescue device.

2.4 FALL PROTECTION WHILE CLIMBING
In situations where it is not practical to install and use a temporary or permanently installed personal fall
arrest system, the winch may be used to guard against falling while climbing a fixed ladder or other
structure. The winch line can be used as essentially a travelling anchorage connector that moves up and
down with the climber. An energy absorbing lanyard is installed between the winch line and the dorsal D-
ring on the climber’s full body harness. The winch must be operated so as to continuously eliminate any
slack in the winch line as the climber moves up and down. The winch operator must be specifically
instructed in such use of this winch. All installations must be designed, installed, and used under the
supervision of a qualified person.
2.5 MATERIAL HANDLING
The winch may be used for the raising and lowering of tools, equipment, and other material not exceeding
the rated Working Load Limit of the winch. Various jurisdictions may not allow the use of the same
equipment to move personnel and material. Be aware of and follow the regulations governing your
workplace.
3. APPLICATION RESTRICTIONS
There are restrictions and limitations that must be carefully considered in the selection, installation, and
operation of this winch. Serious injury or death may result from failure to consider these factors.
3.1 WORKING LOAD LIMIT
This winch is designed and rated to a working load limit of 1 person weighing a maximum of 310lbs
(including all clothing, tools, and equipment) when used in a 1 Part Single Reeved System, or 2 persons
weighing a maximum 620 lbs when used in a 2 Part Single Reeved System (see Figure 2).
Figure 2, 1 & 2 Part Single Reeved Systems
Please refer to the Operator’s Manual(s) for all other accessories in the system to determine which

All installations MUST BE used under the supervision of a Qualified Person.
4.2 COMPATABILITY OF CONNECTORS
Connectors used to connect components in the system must be compatible with each other to ensure
sufficient strength and eliminate the risk of accidental disengagement or rollout during use. Connectors
supplied with products designed, manufactured, and/or approved by Tuff Built Products Inc. will meet all
applicable requirements for connectors. Any connectors not supplied by Tuff Built Products Inc. MUST
BE selected and approved by a Qualified Person.
4.3 FULL BODY HARNESS
Use only a full body harness designed, tested, and approved for fall arrest when connecting a person to
this winch. Body belts or straps do not provide adequate support to the body to prevent serious injury or
death in the event of a fall.

October 18, 2011, Rev 05
5.2.3 RAISING OR LOWERING A WORKER
A worker attached to the winch line is lowered by cranking the winch handle counterclockwise, and raised
by cranking the winch handle clockwise. DO NOT use the winch if the rotation of the winch handle is
reversed, or if the winch does not make a regular clicking sound when cranking the winch handle in a
clockwise direction.
Crank the handle at a smooth and steady pace that you find comfortable to maintain.
Wear gloves if your hands will come in contact with the winch line.
Maintain sufficient tension on the winch line, either from the weight of the worker or manually, to ensure
that the line winds evenly onto the spool. Do not allow any slack line to accumulate between the winch
and the worker if there is any risk of a fall occurring. Serious injury or death may result if a worker falls
while connected to a slack winch line.
6. POWER DRIVE APPLICATIONS
In applications involving repeated positioning activities or long vertical entries, it is sometimes desirable to
have a powered winch rather than relying on manual cranking.
The Pro-Series of winches are designed with a unique input drive hub (see Figure 5) that allows for
convenient switching between manual crank and powered operation while maintaining a manual backup
in the event of power failure or mechanical problems.
Figure 5, Winch Input Drive Hub
Depending on the nature of the application, the regulations governing the use of powered winches to
raise and lower workers in various jurisdictions, and the type and specifications of power drills available,
there are several configurations of Power Drive accessories that may be appropriate (see Figure 6).
