2.3.2 Optional Inspection Hooks
The Inspection Hook is designed to facilitate the inspection of the internal surfaces of the hook
yoke and shank portion of the hook itself. The Inspection Hook is suitable for applications where
inspection of the internal parts of the hook set is required. The inspection hook uses the standard
Harrington hook set and is assembled with high-strength locking fasteners instead of rivets.
Inspection hooks are available in top and bottom versions. Refer to Figure 2-7.
Disassembly and re-assembly involves removal and reinstallation of the yoke fasteners of the
Inspection Hook Set Assembly followed by testing of the hoist prior to returning it to service.
The Inspection Hook is available for CB005 through CB025 hoists.
See Section 9.4, Parts List for a complete Inspection Hook part listing.
Figure 2-7 Inspection Hooks
2.3.3 Optional Chain Containers
Chain containers are sized based on the capacity and lift of the hoist. The containers are
constructed from vinyl coated canvas with a steel frame on top. The containers are prepared
differently depending on the host model. See Harrington document EDOC0154 for sizing
information.

1) Face the hand chain wheel side of the hoist.
2) To raise the load, pull hand chain clockwise.
3) To lower the load, pull hand chain counterclockwise.
NOTE: The clicking sound of the pawl when a load is being raised indicates normal operation.
4.4 Principle and Operation of the Slip Clutch
: IMPROPER chain hoist use could result in death or serious injury. To avoid these hazards:
: NEVER disassemble or attempt to adjust the slip clutch assemby. Any attempt to do so will void
the warranty. Contact your closest Harrington Distributor if service is required.
The standard slip clutch device prevents the hoist from being used to lift damaging loads beyond the rated capacity of
the manual chain hoist. When an applied load exceeds the preset value, the hand chain wheel rotates idly. The
mechanism is a friction clutch system located between the hand chain wheel and the mechanical brake.

5.0 Inspection
5.1 General
5.1.1 The inspection procedure herein is based on ANSI/ASME B30.16. The following definitions are from
ANSI/ASME B30.16 and pertain to the inspection procedure below.
Designated Person
– a person selected or assigned as being competent to perform the specific
duties to which he/she is assigned.
Qualified Person
– a person who, by possession of a recognized degree or certificate of
professional standing, or who, by extensive knowledge, training, and experience, has successfully
demonstrated the ability to solve or resolve problems relating to the subject matter and work.
Normal Service
– that distributed service which involves operation with randomly distributed loads
within the rated load limit, or uniform loads less than 65% of rated load for not more than 15% of

– that service which involves operation within the rated load limit which exceeds
normal service.
Severe Service
5.2 Inspection Classification
– that service which involves normal or heavy service with abnormal operating
conditions.
5.2.1 Initial Inspection – prior to initial use, all new, altered, or modified hoists shall be inspected by a
designated person to ensure compliance with the applicable provisions of this manual.
5.2.2 Inspection Classification – the inspection procedure for hoists in regular service is divided into two
general classifications based upon the intervals at which inspection should be performed. The intervals
in turn are dependent upon the nature of the critical components of the hoist and the degree of their
exposure to wear, deterioration, or malfunction. The two general classifications are herein designated
as FREQUENT and PERIODIC, with respective intervals between inspections as defined below.
5.2.3 FREQUENT Inspection – visual examinations by the operator or other designated personnel with
intervals per the following criteria:
Normal service – monthly
Heavy service – weekly to monthly
Severe service – daily to weekly
Special or infrequent service – as recommended by a qualified person before and after each
occurrence.
5.2.4 PERIODIC Inspection – visual inspection by a designated person with intervals per the following
criteria:
Normal service – yearly
Heavy service – semiannually
Severe service – quarterly
Special or infrequent service – as recommended by a qualified person before the first such
occurrence and as directed by the qualified person for any subsequent occurrences.
17
5.3 Frequent Inspection
5.3.1 Inspections should be made on a FREQUENT basis in accordance with Table 5-1, “Frequent
Inspection.” Included in these FREQUENT Inspections are observations made during operation for
any defects or damage that might appear between Periodic Inspections. Evaluation and resolution of

6.0 Maintenance and Handling
6.1 Lubrication
6.1.1 Load Chain
For longer life, the load chain should be lubricated.
The load chain lubrication should be accomplished after cleaning the load chain with an acid free
cleaning solution.
Apply Harrington lubricating grease (Part No. ER1BS1951) or an equivalent to industrial general
lithium grease, NLGI No. 0, to the bearing surfaces of the load chain links as indicated by the
shaded areas in Figure 6-1. Also apply the grease to the areas of the load chain (shaded areas in
Figure 6-1) that contact the load sheave. Insure that the grease is applied to the contact areas in
the load sheave pockets.
Machine or gear oil (grade ISO VG 46 or 68 oil or equivalent) may be used as an alternative
lubricant but must be applied more frequently.
Figure 6-1 Chain Grease Application
The chain should be lubricated every 3 months (more frequently for heavier usage or severe
conditions).
For dusty environments, it is acceptable to substitute a dry lubricant.
6.1.2 Hooks and Suspension Components:
Hooks – Bearings should be cleaned and lubricated at least once per year for normal usage.
Clean and lubricate more frequently for heavier usage or severe conditions.
Hook Yokes and Latches – Lubricate the hook yokes and hook latches at least twice per year for
normal usage; more frequently for heavier usage or severe conditions.
Suspension Pins - Lubricate the chain pin and the top pin at least twice per year for normal usage;
more frequently for heavier usage or severe conditions.
6.1.3 Applying Grease to Gears:
Remove gear case as instructed in Section 6.3.
Remove old grease and replace the new grease (NLGI No. 3), at annual inspection.
Temperature range of standard grease is -20˚C (-4˚F) to + 60˚C (140˚F). If the hoist is used at
temperatures below -20˚C (-4˚F) or above 60˚C (140˚F), consult the manufacturer or dealer since
some parts should be changed.
