The logic functions provide a secured and controlled flow of goods on the conveyor line by starting and stopping at defined segments with in a conveyorline. The logic functions control the accumulation roller convenyor with precise insertion and removal of goods during distribution

The continuous cycle storage system (dynamic warehouse) consists of gravity roller tables positioned on the ground or incorporated in shelving. The contiguous placement of multiple flow lines and the appropriate exploitation of the height of the storage area by multiple-shelf structures, give these systems great compactness, allowing optimal use of available space.

LATERAL BRACKETS TO BE WELDED Straight brackets made of cold-formed sheet steel, fitted with housing for supporting the roller shaft. ADJUSTABLE LATERAL BRACKETS TO BE WELDED Cold-formed steel sheet brackets, comprising a straight bracket fitted with housing for supporting the roller shaft and a plate, connected to it by means of screw and threaded nut, for fastening to the structure by welding.The slots of the junction housings enable precise adjustment of the roller assembly.The choice and dimensions of the brackets to be adopted depend on the diameter of the roller to be supported, the series to which it belongs and the type of installation to be achieved.

Drums are used in belt conveyors for the handling of bulk materials, with predominant functions of activating (control drums) and tensioning (idler drums) the rubber matting. In the most challenging handling systems such as large mining or port complexes, etc., where hourly flow rates and speeds are high and the distances or differences in altitude to be reached or gained are considerable, they are further distinguished depending on the specific application: contrast drums; deviator drums; tensioning drums.

Garland roller sets are used in belt conveyors that have to handle blunt, bulky, heavy materials. The increased containment capacity of the roller basin facilitates higher speed of transport than those of traditional stations. For upper stations in current use installations, garland sets with 3 and 5 rubberised impact rollers are mounted; for lower stations, garland sets with 2 rollers with scraping rubber rings are mounted.

Due to the structural characteristics of the materials of which they are made, these rollers are used in belt conveyors in handling systems for bulk, humid or sticky materials, in normal, aggressive environments; operating temperature also low. As lower rollers (return) because they prevent the accumulation of material carried by the band, the field of application is specifically on the steel tubes; they thus favour linear and jolt-free running of the rubber matting. They consist of clamped or monobloc base rollers with steel tube and special anti-abrasive rubber rings pressure-aligned on the jacket.

Due to the structural characteristics of the materials of which they are made, these rollers are used in belt conveyors in handling systems of bulk materials, including sharp and abrasive, mixed size, large and heavy materials, in normal, dusty and aggressive environments. As upper rollers, their field of application is specifically in the loading areas of conveyors to protect the rubber matting from the dynamic action of falling materials. They consist of monobloc base rollers with steel tube and special anti-abrasive rubber rings pressure-aligned on the jacket.

Due to the characteristics of the materials of which they are made, these rollers are used in conveyors operating in highly corrosive environmental conditions.With a state-of-the-art manufacture, they possess the requisites of the specifications for steel rollers on page 4. Operating temperature: 10 ÷ +50 [°C].

Steel clamped or monobloc rollers mounted on pre-lubricated and protected radial ball bearings.The externally threaded shaft protrudes from only one end of the tube.In belt conveyors, they are vertically mounted in pairs at the edges of the rubber matting, with the function of restricting any lateral slipping. They are installed on self-centring stations with the same function.The technical characteristics of Series 6 rollers are those of the relative base rollers.Other finishes, see page 30.

They consist of two steel clamped or monobloc rollers mounted on a single “V”-folded shaft. They have the upper bearing mounting heads with hermetic closure and the lower ones, with protruding shaft, with labyrinth dust protection. The shaft is locked in the housing of the central bracket.The latter, with a base plate fitted with mounting holes, is made of cold-formed steel sheet.They are used in concave belt conveyors that operate, even in bad environmental conditions, at medium-high speed, with medium loads and sizes.

Garland roller sets are used in belt conveyors that have to handle blunt, bulky, heavy materials. The increased containment capacity of the roller basin facilitates higher speed of transport than those of traditional stations. For upper stations in current use installations, garland sets with 3 and 5 steel or rubberised impact rollers are mounted; for lower stations, garland sets with 2 steel rollers or with scraping rubber rings are mounted. The flexibility of garland sets enables their adaptation to the material to be transported, facilitates transportation, reduces impacts on the rollers, and limits any lateral slipping of the rubber matting. The diagrams and Table 90 show the shapes of mountings of garland sets envisaged in TECNORULLI’s production programme. Other shapes may be considered on request.

Steel rollers with jacket consisting of tube and bearing mounting head rigidly coupled by welding. They are mounted on pre-lubricated angular or radial ball bearings and protected with double labyrinth, triple labyrinth dust seals with additional watertight protection. Monobloc steel rollers are used in belt conveyors with medium, heavy or very heavy loads. The diagrams and tables on page 42 show the dimensional characteristics and maximum loads.Operating temperature:-10 ÷ +90 [°C].

Steel rollers with jacket consisting of tube and bearing mounting head rigidly coupled by pressure. They are mounted on pre-lubricated angular or radial ball bearings protected with double-labyrinth dust seals. Clamped steel rollers are used in belt conveyors with limited or medium-heavy loads. The diagrams and tables on page 34 show the dimensional characteristics and maximum loads. Operating temperature:-10 ÷ +90 [°C].

The slewing bearing, also known as slew(ing) ring, is a type of bearing for low-speed and high axial load applications. The slewing bearing is a mechanical component that is used in major industrial sectors. Harbor and deck cranes are one of the ideal applications for using slewing bearings – for example, for container handling. Additionally, for wind turbine blades, the use of slewing bearings ensures the highest level of reliability and efficiency, as required by this sector.

Thrust ball bearings are separable axial bearings. Features of thrust ball bearings: ideal for reduced and medium speeds they bear relatively high axial loads separable and easy to assemble Single direction thrust ball bearings can accomodate axial loads in one direction and thus locate a shaft axially in one direction. Double direction thrust ball bearings can accomodate axial loads acting in both directions and thus serve to axially locate a shaft in both directions. These bearings, in both versions, have been designed to withstand only axial loads and must not be subjected to radial loads of any kind.
