(2) Intended use: This hoist has been designed for vertically lifting and lowering load under normal atmospheric conditions of work place.

(3) Noise levels were measured at a distance of 1m horizontally from the hoists during normal operation.

2.2 Mechanical Classification (Grade) and Life

Safety and life for electric wire rope hoists are guaranteed only when the said equipment is operated in accordance with the prescribed grade.

Black Bear electric wire rope hoists have been designed according to FEM-2m regulations (FEM 9.511).

Details are provided in Table 2-2.

Average daily operating time and total operating time are determined by load distribution.

2.3 Safety Devices

(1) Motor brake

"AC Electro-Magnetic Brake" is of a unique design in its field. It features simultaneous motor braking upon removing power even under full load condition.

(2) Mechanical load brake

The mechanical load brake can hold a full capacity load independent of motor brake.

This brake assures that load does not accelerate while being lowered.

(3) Hook and hook latch

The hook is drop - forged from high tensile steel and heat treated for strength and toughness. The button hook is capable of 360°swivel and fitted with safety latch to ensure safe lifting.

(4) Limit Switches

Upper and optional lower limit switches are fitted for switching off power automatically in case of over lifting or over lowering.

(5) Emergency stop device (optional)

This button is used to stop the hoist in an emergency situation. It is a red, mushroom type button, located in the uppermost position on the pendant. When pressed, power to the equipment is switched off and the button locks automatically. Turning it to the right will release the lock and to enable re-starting. (Illust.1)

Illust.1

3. SAFETY RULES

(1) Only the trained personnel are allowed to operate the hoist.

(2)

(3) Prior to each lifting operation, it is essential to make sure that:

(a) the correct lifting sling is being used.

(b) the lifting sling is located in the hook as shown below (Illust.2) and that a safety latch has been fitted.

Illust.2

(c) the object to be hoisted is well secured for direct lifting (a proper lifting frame or apparatus is strongly recommended for direct lifting.)

The hoist herein is not designed for, and should not be used for, lifting, supporting, or transporting personnel.

Any modifications to upgrade , re-rate, or otherwise alter the hoist equipment must be authorized by either the original manufacturer or a qualified professional engineer.

Do not use the hoist in explosive atmosphere.

(4) Firm and steady button operation is required, avoid jogging.

(5) Avoid excessive inching operation.

(6) Always make sure the hoist motor completely stops before reversing.

(7) Always leave the pendant button switch cable and bottom hook vertically static after completion of operation, never leave them at any position, which may allow them swing or slip.

(8) Sling must be applied to load evenly and centrally to ensure correct balance. Never lift any object which is insecure or out of balance.

(9) Never Side load, back load, or tip load a hook. (Illust.3)

(10) Never wrap around and hook back the wire rope as a sling to lift a load. (Illust.4)

Illust.3 Illust.4

(11)

Do not use the Hoist’s wire rope as a welding electrode.

(12)

Illust.5

(13) Lifting must always be personally attended, never leave a raised load unattended.

(14) Over-capacity-load lifting is hazardous and should not be undertaken.

(15) Never lift a load when the wire rope is twisted.

(16) Regularly inspect and check the condition of wire rope. Do not operate with damaged wire rope.

Never stand under a raised load (Illust.5)

4. INSTALLATION

4.1 Unpacking Information

After removing the hoist from its packing box, carefully inspect the external condition of the electrical cables, contactor, gear box and motor casing for damage.

4.2 Voltage

4.3 Installation

If power supply deviates from standard by more than ± 10%, abnormal operation or damage to the motor may result. It is imperative to ensure correct voltage supply before commencing operation.

Connection to power supply before installation procedures having been completed is strictly prohibited.

(1) Prior to installation ,for the Top Running hoist, check dimension “C” & “K” to insure dimension is compatible to the rail size or the gauge between the rails;

for the monorail hoist-please insure trolley adjustment equal to beam’s width.

(Please refer to illustration 6)

Illust.6

(2) Connect power supply to hoist and operate the up push button switch. If the hoist goes down, release the button , go to power source and change (switch) any two wires. Do not modify or change any wires in the push button station.

Illust.7

Monorail Hoist Top Running Hoist

(3) Operation Test

(A) push switch button to lower bottom hook until the drum has only 3 wraps left on the drum.

(B) push switch button to check if the rope winds into the drum grooves.

(C) Check the emergency stop device function (if fitted):

While holding down either or button on the push button switch, push the emergency stop button. Check that the hook stops when the emergency stop button is pushed. Also, verify the hoist does not move in response to the push button switch.

Finally, check that the emergency stop device pops out when turned to the right and that operation can be resumed thereafter. If the equipment fails to pass either of the above checks, check the wiring and automatic locking function of the emergency stop device.

(D) Check to insure upper limit stop works properly by raising the lower block to a point just below engagement. Then carefully jog “UP” into engagement .

When engaged, the “UP” button should be inoperative.

5. OPERATION

After running test and checks have been completed, the hoist will be ready for normal operation.

(1) The operator must have a clear and unobstructed view of the entire working area before operating the hoist.

(2) The operator must check that the entire working area is safe and secure before operating the hoist.

(3) When using the hoist with a motorized trolley, the operator must take care to prevent excessive load swinging by careful use of the trolley controls.

Since dealing with heavy loads may involve unexpected danger, all of the "SAFETY RULES" (Ref 3.) must be followed and the operator must be aware of the following points while using the hoist.

6. MAINTENANCE AND INSPECTION

6.1 Maintenance

(1) Check the level of gearbox lubricant after first 500 hours of operation, thereafter every 3 months and lubricant accordingly.

Note: We recommend using lubricant oil equivalent to ISO VG460 as table of following annual inspection.

(2) Always keep the hoist unit dry and never misuse it in a manner likely to reduce its durability.

(3) When it is necessary to keep the unit outdoors, a protective covering should be fitted.

6.2 Inspection

(1) Daily inspection: Before starting daily operation, check the following,

(a) Correct power supply.

(b) "Up", "Down" and "Emergency stop" (where fitted) test runs under no load.

(c) Correct motor performance.

(d) No abnormal or excessive noise.

(e) No malfunction of the bottom hook safety latch.

(f) Proper function of moving/turning parts, limit switches and brake.

(g) The condition of wire rope and winding evenly over the drum.

(h) Wire rope in of the bottom block’s sheave.

Do not perform maintenance on the hoist while it is carrying a load except monthly checking for the brake or limit switch.

Before performing maintenance do not forget to affix tags to the power source and the push button switch reading: “DANGER”, “EQUIPMENT BEING REPAIRED”.

(2) Monthly inspection

(a) Wire rope:

a-1: Any single strain of wire breaking. Breaking of strains more than 10% should replace new wire rope.

a-2: Any distorted, deform , itching and rusty of wire rope.

a- 3: Wire rope fixing fasteners being deforming of loosing.
