Works trucks of this description include, for example : (A) FORK-LIFT AND OTHER ELEVATING OR STACKING TRUCKS (I) Mechanically propelled fork-lift trucks, which are sometimes of large size, carry the load on an elevating carriage sliding on a vertical mast. This lifting mechanism is normally situated in fkont of the driver's seat; it is designed to support the load during movement and to lift it for stacking or to place it on a vehicle. !in This grou also includes side-loading stacking trucks, which are desi ed to handle long loads (gir!?ers, lanks, pipes, containers, etc.) and are usually equippe with a platform to support the loa ! c during transport over short distances. The lifting device of the above trucks is normally powered by the motive power unit of the vehicle, and is usually designed to be fitted with various s ecial attachments (forks, jibs, buckets, grabs, etc.) according to the type of load to be han ed. dP (2) Other stacking machines, usually mounted on a truck, are equi ped with a platform or fork which can be raised and lowered in a vertical support, by and or power-operated winch or rack systems. They are used for stacking sacks, crates, casks, etc. f~ Some stacking machines which work on the same principle as elevators are classified in heading 84.28. (B) OTHER WORKS TRUCKS FITTED WITH LIFTING OR HANDLING EQUIPMENT This group includes : (I) Trucks with mechanically elevating platforms for the maintenance of electric cables, public lighting systems, etc. (See the introduction to Explanatory Note to heading 84.26 regarding elevating platforms of this type mounted on lorries.)

F X B The headin covers lifting or handling machines usually based on pulley, winch or jacking systems, an often including large proportions of static structural steelwork, etc. These static structural elements (e.g., pylons specialised for teleferics, etc.) are classified in this heading when they are presented as parts of a more or less complete handling machine. When presented s arately, they are classified in headin 84.31 provided they are fitted or designed to be fitte"gwith the mechanical features essential or the operation of the moving parts of the complete installation wheels, rollers, pulleys, running or guide rails, etc.). Otherwise these structural elements are c assified in headlng 73.08. \ F These more complex machines include : (I) INTERMITTENT ACTION MACHINES (A) L i are usually operated by winch and cable, or by rams worked by water, air or oil. They are used for raising or lowering a passenger cage or goods platform between vertical guide bars, and are general1 fitted with counter-balance wei@ts. The control, stoppb, safeq, etc., equi ment, whe er or not electrical, is also classified in this heading provlded it is presente!d with the lift itself, The heading also includes manually operated hfis. X Rack and pinion driven lifts or hoists also belong to this catego consist of a lift cage, fitted with a motor that drives a pinion, toothed rack. When the pinion is engaged with the toothed move along the mast, up or down, at a controlled speed. These lifts and hoists The group also includes so-called " ship-lifts ", i.e., very powefil hydraulic or jack operated mstallations for lifting a vessel and lock basin complete fiom one canal level to another, and thus replacing normal locks. (B) Skiq hoists are a type of lift in which bulk material containers are hoisted up a ram or vertical shaft. They are used for raising coal from mines, for hoisting ores, limestone, Rel, etc., into blast furnaces, lime kilns, etc. The heading also includes skips for such skip hoists, i-e., large ca acity metallic containers or bins often fitted with automatically openin bottoms.
