

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 10) 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 Metal Casting 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; as well as lock and tag the main switch in the de-energized position.

Refer to ANSI Z244.1, “Personnel Protection – Lockout/Tagout of Energy Sources”.

Dual speed units incorporate a VFD as well as a Capacitor. Therefore, DO NOT perform ANY mechanical or

electrical maintenance within 5 minutes of powering down to allow time for the capacitor inside the VFD to

discharge. DO NOT perform any voltage or insulation resistance tests with a meg ohmmeter when the VFD

is connected to the electrical circuit.

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.

A regular schedule of inspection of the hoist in accordance with the requirements of ANSI/ASME B30.16 should be

established and records maintained.

1.2 Warning Tags and Labels

The warning tag illustrated below in Figure 1-1 is supplied with each hoist shipped from the factory. If the tag is

not attached to your hoist’s pendant cord, order a tag from your dealer and install it. Read and obey all

warnings attached to this hoist. Tag is not shown actual size.
