TELESCOPIC HYDRAULIC CYLINDER. THE ARTICLE IS INTENDED FOR SEVERAL USES AND CAN BE: - SIMPLY EFFECTIVE (AFTER THE HYDRAULICALLY OPERATED EXTENSION, THE RETURN IN COMPLETION OF ALL THE ELEMENTS IS ONLY, FOR EXAMPLE, THANKS TO THE WEIGHT OF THE BOX RAISED; IN THIS CASE, HYDRAULIC TELESCOPIC CYLINDER WITH A SIMPLE EFFECT CONSTITUTES AN ACTUATOR FOR THE TILTING OF THE TRUCK CHEST); - DOUBLE ACTING (THEY ARE OPERATED IDRAULICALLY BOTH THE EXTENSION AND THE CLOSURE). THE DUAL EFFECT TELESCOPIC HYDRAULIC CYLINDER CONTAINS LINEAR HYDRAULIC ACTUATOR TO MOVE, FOR EXAMPLE, THE INTERNAL BULKHEAD OF WASTE COLLECTION VEHICLES, FOR THE COMPACTION AND THE EXPULSION OF THE SAME. THE DISTINCTIVE ELEMENT OF THE DOUBLE EFFECT TELESCOPIC HYDRAULIC CYLINDERS COMPARED TO THE SIMPLE EFFECT TELESCOPIC HYDRAULIC CYLINDERS IS GIVEN BY AN ADDITIONAL GASKET PUT INSIDE THE CYLINDER IN THE STANTUFFO ZONE. THE CYLINDER CAN HAVE DIFFERENT DIMENSIONS, STILL HOLDING THE SAME AS TECHNICAL AND FUNCTIONAL FEATURES: DIAMETERS FROM 30 TO 400 MM. , CYLINDER LENGTH ALL CLOSED FROM 150 TO 3000 MM. , CYLINDER LENGTH ALL OPEN FROM 300 TO 15000 MM. FROM THEIR POSITION OF REST, THE COMPONENT CYLINDRICAL ELEMENTS SHOW AND EXTEND UNDER THE STRENGTH OF A HYDRAULIC PRESSURE (HYDRAULIC OIL). THE ARTICLE CONSISTS OF A STEEL STRUCTURE, WITH GASKETS AND SCRAPERS IN POLYURETHANE, RUBBER, PTFE LOADED BRONZE AND GUIDE RINGS IN POM (GLASS LOADED ACETAL RESIN). THE CYLINDER IN ACCORDANCE WITH THE CUSTOMS OPERATION DOES NOT INCLUDE OTHER TYPICAL ELEMENTS OF A HYDRAULIC SYSTEM (ENGINE, PUMP, ETC.).
