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.



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
the time.

Heavy Service – that service which involves operation within the rated load limit which exceeds
normal service.

Severe Service

– that service which involves normal or heavy service with abnormal operating

conditions.

5.2 Inspection Classification

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:

– a person selected or assigned as being competent to perform the specific

 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.

16

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



Hoist Idle More Than 1 Year

5.6 Inspection Records

5.6.1 Dated inspection reports and records should be maintained at time intervals corresponding to those
that apply for the hoist’s PERIODIC interval per Section 5.2.4. These records should be stored where
they are available to personnel involved with the inspection, maintenance, or operation of the hoist.

5.6.2 A long range chain inspection program should be established and should include records of
examination of chains removed from service so a relationship can be established between visual
observation and actual condition of the chain.

5.7 Inspection Methods and Criteria

5.7.1 This section covers the inspection of specific items. The list of items in this section is based on those
listed in ANSI/ASME B30.16 for the Frequent and Periodic Inspection.

5.7.2 Frequent Inspection - Not intended to involve disassembly of the hoist. Disassembly for further
inspection would be required only if frequent inspection results so indicate. Disassembly and further
inspection should only be performed by a qualified person trained in the disassembly and re-assembly
of the hoist.

5.7.3 Periodic Inspection - Disassembly of the hoist is required. Disassambly should only be performed by a
qualified person trained in the disassembly and re-assembly of the hoist.

6.0 Maintenance and H andling

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.

If a defect is found in the hoist, stop using it immediately and check the cause of the defect.
Only Trained and competent personnel should inspect and repair the hoist.

Table 7-1 Troubleshooting Guide

Note on proper operation:

 When lifting, the hoist should make clicking sounds when moving the hand wheel.
 When lowering, the hoist should not make clicking sounds when moving the hand wheel.

Symptom Cause Remedy

Hoist will not lift –
Slight clicking

Hoist will not lift –
Not Clicking

Hoist will not lift –
Hand wheel will not

operate

Improper assembly of ratchet disc, disc
installed backwards, and making incorrect
contact with the pawl.

Reassemble the pawl and ratchet disc
properly. Ensure that clicking sounds are
heard before reuse.

Clean and lubricate pawl and pawl shaft.

Pawl not engaging ratchet disc:

 Dirt or corrosion between pawl and pawl

shaft.

Faulty pawl spring Replace pawl spring
Loose selector pawl spring Perform hoist maintenance.

Reassemble gears properly and ensure
smooth operation before reuse.

Ensure the ‘0’ & “V”
marks of gear #2 are aligned properly, as
shown.

Gear #2 improperly timed
