to be carried out. Controls are mounted on / in the platform / cage.
Gantry / Chain Blocks / Pillar Cranes
Normally mounted on runway tracks or manual cranes, powered hoist blocks are widely used in all industry sectors.
Normally electrically or pneumatically powered, these units hoist loads via a load hook and integral steel chain or wire rope. Lifting capacity can be as much as 10 tonnes.
Winches are of similar design and can be used for a variety of duties ranging from hauling loads horizontally to lifting or lowering loads in a vertical plane.
Pillar cranes are widely used throughout the retread industry for stacking tyres/casings also attached to the mould presses for loading and unloading.
Point to note:-
If you have any sort of mechanical handling equipment that supports and moves a load in a vertical or horizontal plain, then it will require inspection at regular intervals, the equipment may also require recertification testing for safe work load (SWL) on completion of any repair and maintenance, if unsure about inspection and testing requirements you should contact you insurance inspection service provider.
Common occurrences:-
A ‘serious’ (but often overlooked by the operator) defect on lift trucks is wear in excess of 10% at the fork heels. The engineer will have to report this defect, and you will have to rectify worn fork heels. The engineer (in the UK) is bound by the guidance issued by the HSE and information within BS ISO 5057. Guidance is provided on inspection of fork arms, surface cracks, straightness of blade, fork angle, difference in height of fork tip and of set of fork arms etc.
BS ISO 5057 rejects fork arms that are worn at the heel more than 10% of the original thickness of the metal.
It is recommended that repairs are only carried out by the fork arm manufacturer. If welding is carried out, the welding method will need to include welding preparation, pre-heating, stress relieving and re- heat treatment within the manufacturer’s specification.
Use of mild steel materials and ordinar y jobbing welding methods are likely to result in an unsatisfactory and unsafe repair. Most manufacturers do not even recommend welding at the heels of the forks to replace metal removed by wear as this only replaces the thickness and not the strength. Welding may in fact do further harm by mismatching of metals, localised heating and lack of heat treatment.
To counteract the expensive repairs or replacement, regular refresher training of forklift truck operators to raise forks whenever possible to
prevent damage is advised.
Thorough Examination Frequency?
How often do you have to ensure a ‘thorough examination’ conducted on lifting plant?
Under LOLER a ‘thorough examination’ is typically required every 12 months. Lifting attachments, accessories and machines for lifting persons need examination every six months.
Common practice!! Lifting a person on your lift truck?
The only acceptable use of a lift truck lifting persons in exceptional circumstances is using a
specifically designed and tested carrier or working platform: Purpose built units are normally available from the manufacturer of the truck.
A more appropriate method of working at heights should be employed such as permanent/temporary scaffold or a mobile elevating work platform.
A person should never be lifted on the forks, pallet or bucket on the front of a lift truck under any circumstances.
The recognised minimum examination frequency of a lift truck used to lift a person is six months.
