Preface

Congratulations on your CRANE Lever Block purchase.

The CRANE Lever Block you have chosen, is a top quality & heavy

duty hoist, designed to retain its operational features under normal

operating conditions. In order to achieve years of satisfactory

service from your CRANE Lever Block regular maintenance and

lubrication should be applied.

Prior to operation, please read all the contents contained within this

manual. At all times only competent and experienced personnel

should operate, install or maintain this hoist. Failure to comply with

the instructions contained within this manual can result in both

physical and/or property damage.

In keeping with statutory requirements, and best use for your

CRANE Lever Block we recommended a periodic maintenance check

every 12 months.

Initial Set Up Check

Your CRANE Lever Block has been tested, and conforms to

Australian Standard AS1418.2 - 1997

On completion of installation, but prior to your CRANE Lever

Block being put into regular service, the following procedures

should be carried out:

1. Check that all joints and fasteners are tight and secure.

2. Check operation of hoist brake, under light load and full load

conditions.

3. Operate the hoist with both no load and full load, and check

that the operation is smooth at all times.

Order Information

Replacement parts is your require spare parts for your Lever Block

in the future. Simply provide the Model No., Serial No. and the part

you require to your local CRANE distributor.

Instructions

Principle and Operation of Free Chain Adjusting System -

Free Chain Adjusting Principle.

WARNING IMPROPER use of chain lever blocks could result

in death or serious injury. To avoid these hazards: please read &

follow the instructions in this owners manual.

WARNING NEVER operate the free chain adjusting device while

load is applied to chain lever block.

WARNING NEVER touch the free knob during lifting or lowering

of the load.

Note: The break is engaged automatically

during lowering or lifting of the load. Free

chain adjusting is achieved by releasing the

brake during no-load.

Step Action

1. Set the charge-over knob to “N”. The change-over knob is

located under the free knob on the hand lever.

2. Rotate the “Free” knob slightly in desired direction.

3. Pull the load chain to move the hook to the desired location.

4. By “setting” the change-over knob to “Up” or “Down” , this

will reset the break and allow the hoist to be operated with

the hand lever.

Method

Principle of Lifting and Lowering Operation - Lifting and

Lowering Principle

By setting the change-over knob to “UP” or “DOWN”, and operating

the lever, the female thread and the change-over pawl inside the

hoist engage and the female thread rotates in either the lifting

or lowering direction. The brake works instantly after the lever

operation stops and holds the load.

Lifting and Lowering

Select direction of movement and ratchet hand lever back and

forth, see below:

NOTE 1: If hand lever movement does not produce lifting, pull

down the load chain while ratcheting until slack is removed.

NOTE 2: PRE-LOAD is the minimum load that must be applied to

the lever block before the braking system activates. The PRE-LOAD

on the CRANE Lever block is set approximately 3% of the W.L.L.

(Working Load Limit) of the particular Lever Block. eg. (800Kg lever

hoist 24kg), (1600kg lever hoist 48kg), (3200kg lever hoist 96kg),

(6300kg lever hoist 189kg), (9000kg lever hoist 270kg).

Safety Procedures

The following Safety section should form part of the safety rules

for any plant where any hoist or other lifting equipment is being

used, serviced or repaired.

Any person(s) operating the hoist should read and observe

the following safety instructions and the instructions in the

Operating section, to avoid operating hazards.

Always Check for any cracks or wear signs on the unit before use

and ensure you are working in a safe environment before use.

1. DO NOT load beyond the rated capacity.

2. DO NOT heat treat and DO NOT weld any part of the

lever block, especially the load chain.

3. DO NOT leave a load on the lever block unattended.

4. DO NOT shock load lever block, chain or hook.

5. DO NOT operate the lever block unless it is rigged to

pull in a straight line from hook to hook, and the frame is

allowed to freely swivel on the upper hook.

6. DO NOT hold the load chain in a loaded state while

operating the lever block as serious injury may occur if

the brake did not operate properly.

7. DO NOT wrap the load chain around the load and hook

onto itself as a choker chain, or bring the load in contact

with the lever block.

8. DO NOT use this lever block for lifting or moving people,

or lifting loads over people.

9. DO NOT take up the load chain to the point where the

end ring or lower hook becomes jammed against the

frame.

10. DO NOT use an extension pipe or cheater bar to apply

more pressure to the lever handle.

11. DO NOT Repair unless you are fully qualified to do so.

12. Do Not allow your attention to being diverted whilst

lifting the load.

Care in Use

1. Always examine the hoist carefully before use - your life may

be at stake. Look for cracks or damage, particularly with hooks

and load chain.

2. Keep load chain clean and oiled to prevent undue damage or

wear. When in use, avoid dragging the load chain through dirt

or mud.

3. When the hoist is used outdoors or in a corrosive environment,

ensure that it is regularly and adequately lubricated.

4. Do not operate the hoist if you do not have a clear view of the

bottom hook and the load.

WARNING

If a load hook has been distorted, due to an overload on the

hoist, then the hoist lifting unit will also be damaged. A hoist

which has been overloaded must be withdrawn from service

immediately.
