Manual Balance Crane Fork CFA type

H-Lift Manual Balance Crane Fork CFA Type
Crane Forks: A device used in conjunction with a crane or other lifting machine to lift palletised loads of the type more normally associated with fork lift trucks.

• Manual balance crane fork needs the operator to adjust the hoist hook position on the forks to ensure the load is picked up correctly.
• Easily adjustable tines for all pallet sizes.
• Maintenance free.
• Highly visible safety colour.
• For transporting rings or coils, simply push fork tines together.
• Supplied with chain for securing the load.
• Safety Factor: 4:1.
• Standard: EN 13155, AS 4991, B 30.20

• Crane forks with manual weight balancer, adjustable height. These crane forks are equipped with adjustable tines and height adjustability. The balancing system engages when the shackle is manually hooked into the appropriate notch.
• Crane forks with automatic weight balancer, adjustable height. These crane forks are equipped with adjustable tines, height adjustability and an automatic balancing system.

PRINCIPLES FOR THE SELECTION OF CRANE FORKS
Applications
Crane forks are suitable for lifting palletised loads in many situations where a forklift truck cannot operate or would prove to be inadequate, e.g. where substantial heights of lift are required. They may be used for a specific application, i.e. where identical loads are lifted each time, or perhaps more typically may be used as general purpose lifting accessories to lift a variety of loads which may vary in size, shape and weight.
It is strongly recommended that the exact nature of the application is adequately discussed between the user and the supplier.

Consideration should be given to the following:
(1) Lifting capacity required.
(2) Adjustment required to facilitate varying loads, e.g. suspension eye and fork arms.
(3) Available headroom.
(4) The self-weight of the crane fork.
(5) Degree of portability required.
(6) Method of control and control features required, e.g. grab handles.
(7) Proximity of persons during operations.
(8) Other safety features required, e.g. secondary positive holding device.
(9) The documentation required by legislation. If this is not on record, refer the crane fork to a Competent Person for thorough examination.

SAFE USE OF CRANE FORKS
In addition to any specific instructions relating to safe use issued by the manufacturer, the following points
should be observed:
(1) Do not use to lift people.
(2) Do not lift loads over people who are in the danger zone unless the crane fork has the features needed to address this situation. These features usually include a secondary positive holding device. If the crane fork does not have such features, it will be necessary to exclude persons from the danger zone.
(3) Ensure that the fork arms of the crane fork are correctly adjusted for width.
(4) Use the grab handles to control the crane fork and ensure that it is presented to the load so that the fork arms pass right through the pallet at the appropriate positions.
(5) The condition of the load is of paramount importance. The load itself must be capable of being lifted safely and of withstanding the forces imposed upon it. Loads comprised of loosely stacked materials should not be lifted. Such loads require additional security such as strapping or netting to keep them in place.
(6) For crane forks fitted with manual adjustment, position the lifting eye so that the load will hang correctly when lifted.
(7) Make a trial lift to ensure that the load hangs correctly. When lifted, the fork arms should be tilted backwards by an angle equal to or slightly greater than 5º to prevent the load from sliding off the fork arms.
(8) Adjust as necessary before proceeding. For crane forks with a fixed suspension, this will require repositioning of the crane fork within the load.
(9) Be aware that a crane fork with an automatic mechanism to adjust the position of the lifting eye may not work at very low loads. Check the manufacturer’s instructions for any minimum load information.
(10) Be aware of the danger of unbalanced loads causing the crane fork to tilt sideways. The C of G of the load should be located centrally between the fork arms.
(11) Do not use for operations other than those specified.
(12) Do not attempt to hoist the load until you are satisfied that the crane fork is capable of doing so. Methods of ensuring this will vary from one manufacturer to another and it is essential that the manufacturers’ instructions relevant to the particular type of crane fork are consulted. Do not subject the crane forks to shock loads particularly once the load has been raised.
(13) Be aware of the pendulum effect of a load attached to a crane hook.
(14) Remember to include the self weight of the crane fork when calculating the total load on the lifting machine.
(15) When the load comprises a stack or bundle, e.g. blocks or sheets, care must be taken to ensure that the stack or bundle is held together during the lifting operation. This may necessitate the use of strap banding or netting. Alternatively the crane fork may have a built in securing mechanism or clamp.

A manual balance crane fork is a type of lifting device used for transporting and lifting heavy loads in a warehouse or industrial setting. It consists of a pair of long, slender arms or forks, which are mounted on a central pivot point and can be adjusted to maintain balance while carrying a load.

Manual balance crane forks are typically operated by a person who pushes or pulls the device into position, using the forks to lift and move heavy objects. The operator must use caution when maneuvering the device, as it can be unstable if the load is not evenly distributed between the forks.

To use a manual balance crane fork, the forks are positioned on either side of the load, and the operator slowly raises the load by pulling or pushing on the handle or lever. Once the load is lifted, the operator can then push or pull the device to move the load to its desired location.

Manual balance crane forks are typically used in environments where a large, heavy load needs to be transported short distances, such as in a warehouse or factory setting. They are typically designed for relatively light loads and are not suitable for lifting extremely heavy objects.

It is important to follow proper safety protocols when using a manual balance crane fork, such as wearing appropriate protective gear and ensuring that the load is properly secured before lifting. Additionally, the device should be inspected regularly to ensure that it is in good working condition and free from defects.
