1.0 Important Information and Warnings
1.1 Terms and Summary
This manual provides impor tant infor mation for personnel involved with the installation, operation and maintenance
of this product. Although you may be familiar with this or similar equipment, it is strongly recommended that you read
this manual before installing, operating or maintaining the product.
Danger, Warning, Cauti on and Notic e
Throughout this manual there are steps and procedures that can present hazardous situations. The following signal
words are used to identify the degree or level of hazard seriousness.
Danger indicates an imminently hazardous situation which, if not avoided, will result in death or
serious injury, and property damage.
Warning indicates an imminently hazardous situation which, if not avoided, could result in death or
serious injury, and property damage.
Caution indicates a potentially hazardous situation which, if not avoided, may result minor or
moderate injury or property damage.
Notice is used to notify people of installation, operation, or maintenance information which is
important but not directly hazard-related.
These general instructions deal with the normal installation, operation, and maintenance situations encountered with
the equipment described herein. The instructions should not be interpreted to anticipate every possible contingency
or to anticipate the final system, crane, or configuration that uses this equipment. For systems using the equipment
covered by this manual, the supplier and owner of the system are responsible for the system’s compliance with all
applicable industry standards, and with all applicable federal, state and local regulations/codes.
This manual includes instructions and parts information for a variety of hoist types. Therefore, all instructions and
parts information may not apply to any one type or size of specific hoist. Disregard those portions of the instructions
that do not apply.
Record your hoist’s Code, Lot and Serial Number (see Section 9) on the front cover of this manual for identification
and future reference to avoid referring to the wrong manual for information or instructions on installation, operation,
inspection, maintenance, or parts.
Use only Harrington authorized replacement parts in the service and maintenance of this hoist.

Equipment described herein is not designed for and MUST NOT be used for lifting, supporting, or transporting
people, or for lifting or supporting loads over people.
Equipment described herein should not be used in conjunction with other equipment unless necessary and/or
required safety devices applicable to the system, crane, or application are installed by the system designer, system
manufacturer, crane manufacturer, installer, or user.
Modifications to upgrade, rerate, or otherwise alter this equipment shall be authorized only by the original equipment
manufacturer.
Equipment described herein may be used in the design and manufacture of cranes or monorails. Additional
equipment or devices may be required for the crane and monorail to comply with applicable crane design and
safety standards. The crane designer, crane manufacturer, or user is responsible to furnish these additional items
for compliance. Refer to ANSI/ASME B30.17, “Safety Standard for Top-Running Single Girder Cranes”;
ANSI/ASME B30.2 “Safety Standard for Top-Running Double-Girder Cranes”; and ANSI/ASME B30.11 “Safety
Standard for Underhung Cranes and Monorails”.
If a below-the-hook lifting device or sling is used with a hoist, refer to ANSI/ASME B30.9, “Safety Standard for
Slings” or ANSI/ASME B30.20, “Safety Standard for Below-the-Hook Lifting Devices”.
Hoists and cranes, used to handle hot molten material may require additional equipment or devices. Refer to ANSI
Z241.2, “Safety Requirements for Melting and Pouring of Metals in the Metalcasting Industry”.
Electrical equipment described herein is designed and built in compliance with Harrington's interpretation of
ANSI/NFPA 70, “National Electrical Code”. The system designer, system manufacturer, crane designer, crane
manufacturer, installer, or user is responsible to assure that the installation and associated wiring of these electrical
components is in compliance with ANSI/NFPA 70, and all applicable Federal, State and Local Codes.
Failure to read and comply with any one of the limitations noted herein can result in serious bodily injury or death,
and/or property damage.

HAZARDOUS VOLTAGES ARE PRESENT IN THE CONTROL BOX, OTHER ELECTRICAL COMPONENTS,
AND CONNECTIONS BETWEEN THESE COMPONENTS.
Before performing ANY mechanical or electrical maintenance on the equipment, de-energize (disconnect) the main
switch supplying power to the equipment; and lock and tag the main switch in the de-energized position. Refer to
ANSI Z244.1, “Personnel Protection – Lockout/Tagout of Energy Sources”.
Only trained and competent personnel should inspect and repair this equipment.
It is the responsibility of the owner/user to install, inspect, test, maintain, and operate a hoist in accordance with
ANSI/ASME B30.16, “Safety Standard for Overhead Hoists”, OSHA Regulations and ANSI/NFPA 70, National
Electric Code. If the hoist is installed as part of a total lifting system, such as an overhead crane or monorail, it is
also the responsibility of the owner/user to comply with the applicable ANSI/ASME B30 volume that addresses that
type of equipment.
It is the responsibility of the owner/user to have all personnel that will install, inspect, test, maintain, and operate a
hoist read the contents of this manual and applicable portions of ANSI/ASME B30.16, “Safety Standard for
Overhead Hoists”, OSHA Regulations and ANSI/NFPA 70, “National Electric Code”. If the hoist is installed as part
of a total lifting system, such as an overhead crane, the applicable ANSI/ASME B30 volume that addresses that
type of equipment must also be read by all personnel.
If the hoist owner/user requires additional information, or if any information in the manual is not clear, contact
Harrington or the distributor of the hoist. Do not install, inspect, test, maintain, or operate this hoist unless this
information is fully understood.

buttons – one for raising and one for lowering.
Pendant Cord
The Pendant Cord is hard wired to the hoist. Make this connection as follows:
