1.0 Important Information and Warnings

1.1 Terms and Summary

This manual provides important information 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, Caution and Notice – 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.

WARNING

CAUTION

NOTICE

This manual chain hoist is designed and manufactured to lift and lower a load manually within a normal work environment. Movement in
the horizontal direction is also enabled by combining with a trolley. The operation of a hoist involves more than activating the hoist’s
controls. Per the ANSI/ASME B30 standards, the use of a hoist is subject to certain hazards that cannot be mitigated by engineered
features, but only by the exercise of intelligence, care, common sense, and experience in anticipating the effects and results of activating
the hoist’s controls. Use this guidance in conjunction with other warnings, cautions, and notices in this manual to govern the operation and
use of your hoist.

1.2 Shall’s and Shall Not’s for Operation

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.

Improper operation of a hoist can create a potentially hazardous situation which, if not
avoided, could result in death
avoid such a potentially hazardous situation THE OPERATOR SHALL:

• NOT use hoist before reading Owner's Manual.
lift more than rated load for the hoist.

• NOT

• NOT

operate a hoist which has been modified without the

manufacturer's approval or certification to be in conformity with
applicable OSHA regs.

• NOT

operate hoist when it is restricted from forming a straight

line from hook to hook in the direction of loading.

• NOT

use hoist with twisted, kinked, damaged, or worn chain.

• NOT

use damaged hoist or hoist that is not working properly.

• NOT

operate a malfunctioning or unusually performing hoist.

• NOT

use the hoist to lift, support, or transport people.

• NOT

lift loads over people.

• NOT

remove or obscure the warnings on the hoist.
use load chain as a sling or wrap load chain around load.

• NOT

• NOT

use in a way that causes either hook to be side loaded.

• NOT

apply the load to the tip of the hook or to the hook latch.

• NOT

use hoist if hook latch is missing or malfunctioning.

• NOT

apply load unless load chain is properly seated in the load

sheave.

• NOT

use the hoist in such a way that could result in shock or

impact loads being applied to the hoist.

• NOT

attempt to lengthen the load chain or repair damaged load

chain or hand chain.

• NOT

operate beyond the limits of the load chain travel.

Page 1 of 6

leave load supported by the hoist unattended unless

• NOT
specific precautions have been taken.

• NOT

allow the chain, or hook to be used as an electrical or

welding ground.

• NOT

allow the chain, or hook to be touched by a live welding

electrode.

• NOT

operate a hoist on which the safety placards or decals are

missing or illegible.

• Be familiar with operating controls, procedures, and warnings.

• Make sure the unit is securely attached to a suitable support
before applying load.

• Make sure load slings or other approved single attachments are
properly sized, rigged, and seated in the hook saddle.

• Take up slack carefully - make sure load is balanced and load­holding action is secure before continuing.

• Make sure all persons stay clear of the supported load.

• Protect the hoist’s load chain from weld splatter or other
damaging contaminants.

• Report Malfunctions or unusual performances (including unusual
noises) of the hoist and remove the hoist from service until the
malfunction or unusual performance is resolved.

• Warn personnel before lifting or moving a load.

• Warn personnel of an approaching load.

Improper operation of a hoist can create a potentially hazardous situation which, if not avoided, could result in minor

moderate

injury, or property damage. To avoid such a potentially hazardous situation THE OPERATOR SHALL:

• Maintain a firm footing or be otherwise secured when operating
the hoist.

• Check brake function by tensioning the hoist prior to each lift
operation.

• Use hook latches. Latches are to retain slings, chains, etc. under
slack conditions only.

• Make sure the hook latches are closed and not supporting any
parts of the load.

• Make sure the load is free to move and will clear all obstructions.

• Avoid swinging the load or hook.

• Make sure hook travel is in the same direction as shown on
controls.

Inspect the hoist regularly, replace damaged or worn parts, and

•

keep appropriate records of maintenance.

use. Inspect all load suspension members for damage prior to use and replace or repair all damaged parts.

3.3.2 Measure and record the “k” dimension of the top and bottom hook. See Table 5-4 under Section 5.0, “Inspection”.

3.3.3 Record the hoist's Code, Lot and Serial Number (from the name plate on the hoist; see Section 2.1.4) in the space provided on the
cover of this manual.

3.3.4 Ensure that the hoist is properly installed to a fixed point.

3.3.5 Ensure that all nuts and bolts are sufficiently fastened.

3.3.6 Confirm proper operation:

• Before operating read and become familiar with Section 4 - Operation.

• Before operating ensure that the hoist meets the Inspection, Testing and Maintenance requirements of ANSI/ASME B30.16.

• Before operating ensure that nothing will interfere with the full range of the hoist’s operation.

Prior to mounting the hoist ensure that the suspension and the supporting structure are adequate to support the hoist

Ensure that the fixed suspension point rests on the center of the hook’s saddle and that the hook’s latch is engaged.

Confirm the adequacy of the rated capacity for all slings, chains, wire ropes and all other lifting attachments before

5.0 Inspection

5.1 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 Inspection Classification – The inspection procedure herein is based on ANSI/ASME B30.16. Inspections for hoists in regular service

are divided into FREQUENT and PERIODIC groups based upon the intervals at which inspection should be performed. The intervals in
turn are dependent upon the degree of service and usage the hoists are subjected to. The two general classifications are herein
designated as FREQUENT and PERIODIC, with respective intervals between inspections as defined in Table 4-1.

5.3.1 Inspections should be made on a FREQUENT basis in accordance with Table 5-2, “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 the results of FREQUENT Inspections shall be made by a designated person such that
the hoist is maintained in safe working condition.

5.4 Periodic Inspection

5.4.1 Inspections should be made on a PERIODIC basis in accordance with Table 5-3, “Periodic Inspection.” Evaluation and resolution of

the results of PERIODIC Inspections shall be made by a designated person such that the hoist is maintained in safe working
condition.

5.4.2 For inspections where load suspension parts of the hoist are disassembled, a load test per ANSI/ASME B30.16 must be performed

on the hoist after it is re-assembled and prior to its return to service.

5.5 Inspection Methods and Criteria

5.5.1 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.

5.5.2 Frequent Inspection - Not intended to involve disassembly of the hoist. Disassembly for further inspection would be required if 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.

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