6.0 Operation

Use of the web strap hoist

around energized lines may result in serious or fatal injury. It is the operator’s responsi bility to understand and compl y with OSHA re gulations and/or company work practices when operating hoist around electrical lines.

The web strap ratchet hoist will operate right side up, upside down, or at an angle. For maximum pulling power, rig the unit for double line (JWS-25A and JWS-4A only). For half the capacity but greater operating speed and pulling distance, use single line. See Figure 5-1.

Always position hoist so that it hangs freely and has free side-to-side movement.

Always inspect the hoist before each use. If any damage is found, do not use the hoist.

Do not attempt free-wheel

while hoist is under load.

If lever is set to UP position,

handle will rotate during free-wheel and may cause injury. Set lever to N (Neutral) position before free-wheeling.

Hoist frame, strap and hooks should be aligned in direction of loading to prevent side pull.

Make sure one full wrap of web strap remains on shaft before applying load.

Load should be properly seated in the saddle of the hook.

Use steady strokes of the handle. When beginning to lift or pull, move load a few

inches and check for proper load holding action before continuing.

6.1 General procedures

See Figure 6-1.

Figure 6-1: lever shown in neutral position

Pulling load – Push lever to UP arrow position and operate handle. The wing nut can also be rotated to pull in the strap when there is light or no load. (Handle will remain stationary when using wing nut for this.)

Releasing load – Push lever to DOWN arrow position, and operate handle.

Neutral – Push lever to N position. Handle is disengaged, but wing nut can still be rotated to pull load.

Free-wheel – Set lever to N, and release pawl by pressing upper end with your finger (you may have to move wing nut slightly to disengage pawl). Unreel strap by hand.

7.0 User-maintenance

Do not perform any

maintenance while hoist is under load.

7.1 Cleaning and lubrication

Clean metal parts and web strap with soap or detergent and water, as needed. Allow web strap to dry completely before using hoist.

Lubricate ratchet wheel sparingly with a general purpose machine oil. Wipe off excess. Do not get oil or grease on the web strap. Do not apply grease to the braking mechanism.

7.2 Web strap replacement

1. Place hoist in Neutral position and release pawl. Pull strap all the way out by hand.

2. Remove two screws and clamping block (#28,29, exploded view) with 5mm hex key. Remove old strap and pin (#30).

3. Insert pin (#30) into loop of new strap. Install strap, clamping block and screws. Securely tighten screws.

4. Push direction lever to UP position and wind strap onto drum.

7.3 Storage

The hoist should be stored away from direct sunlight, dirt, oil, water, high humidity or corrosive materials that can damage the web strap.

7.4 Additional servicing

Any other servicing should be performed by an authorized service representative.

8.0 Hook wear limits

Figure 8-1 shows normal hook measurements A, B and C. The hook must be replaced if any distortion causes a 10% or more change in these dimensions. Never heat-treat the hook or attach anything to the hook by welding.

NOTE: Excessive hook throat opening or twist indicates abuse or overloading of the hoist. If such deformation is discovered, inspect the hoist and all supporting members very carefully for additional indications of excessive hoist loading.

Hook Limits for JWS-series Web Strap Hoists Normal Replace

If = or > than A 29 mm (1.14 in.) 32 mm (1.25 in.) B 15.1 mm (0.59 in.) 16.6 mm (0.65 in.) C 15 mm (0.59 in.) 16.5 mm (0.65 in.)

Table 2 Figure 8-1

9.0 Inspection and maintenance

All repairs and adjustments are to be performed by qualified persons using procedures

that are approved for the hoist system being serviced. All safety-related d eficiencies discovered in the inspection are to be corrected before hoist is placed back into service.

Read and follow all relevant ANSI Inspection and Maintenance standards, particularly ANSI/ASME B30.21 Lever Hoists. Know the meaning of Frequent Inspection, Periodic Inspection, Normal Service, Heavy Service, and

Severe Service. It is the customer’s responsibility to understand and follow all ANSI and JET inspection and maintenance instructions.

The following definitions are based upon ANSI/ASME B30.21.

Normal Service: Operation with randomly distributed loads within the rated load limit or uniform loads less than 65% of rated load for not more than 25% of the time.

Heavy Service: Operation within rated load limit, which exceeds normal service. Severe Service: Normal or heavy service with abnormal operating conditions. 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 a recognized degree or certificate of professional standing, or who, by

extensive knowledge, training, and experience, has successfully dem onstrated the ability to solve or resolve problems relating to the subject matter and work.

10.0 Inspection schedules

The JWS-series Web Strap Hoist should be given an initial inspection upon installation and prior to use. Following that, it must be inspected by a designated person at the time interval noted below. Dated inspection and repair reports must be maintained. Copies of all reports must be available to service personnel.
