Product catalog summary
Introduction
The document outlines technical specifications and guidelines for the UP Series screw jacks, emphasizing the importance of selecting the correct model and size based on application needs. It highlights that the manufacturer cannot predict usage conditions, and assistance is available for product selection.
Specifications
  • Housing: Sizes 2.5, 5, 10, and 25 use aluminum alloy, while sizes 50 and 100 use cast iron. Optional treatments include anodizing for specific industries.
  • Worm Gear - Worm Wheel Set: Made from case-hardened steel and bronze.
  • Bearings: High-quality bearings ensure performance, with different types used based on size.
  • Screw Spindle: Made of carbon steel with options for different threads and materials.
  • Nut: Made of bronze, with optional lubrication-free polymers.
  • Seals: Radial seals ensure hermetic sealing, with special options available.
Lubrication
  • Jack Gearbox: Filled with synthetic grease for lifetime lubrication, with an oil option available.
  • Screw Spindle: Requires regular inspection and lubrication by the user.
Load Definition
  • Static and Dynamic Loads: Defined based on the jack's state of motion.
  • Pull and Push Loads: Defined by direction relative to the jack housing.
Maximum Permissible Loads
The jacks are designed for nominal static loads, with guidelines provided for different mounting scenarios to avoid load limitations.
Backlash and Wear
  • Axial Backlash: Necessary for functioning, detectable during load transitions.
  • Nut Wear: Regular checks required, with a wear limit of 25% of the pitch.
Installation Guidelines
  • Ensure axial loads only, maintain system alignment, and follow maintenance manuals.
Calculation Section
  • Sizing a Single Jack: Evaluate loads and calculate necessary torque, power, and speed.
  • Sizing a Multi-Jack System: Sum individual torques and adjust for friction losses.
Buckling Load Check
Verify screw at buckling load using Euler diagrams based on constraints.
Assembly Diagrams
Illustrate various configurations with efficiency values.

UNSERE GESCHICHTE La storia inizia da molto lontano, nel 1946, quando Didimo Zanetti e il fratello Augusto iniziano un’attività artigianale nel settore meccanico. In quel tempo era appena finita la Seconda Guerra Mondiale, tutto era da ricostruire e nessuno si rendeva conto che le opportunità erano enormi. Infatti molti tecnici abili ed esperti, che vennero licenziati da aziende storiche come la Ducati di Bologna (che nel periodo bellico aveva grandi commesse che cessarono, appunto, con la fine del conflitto) si ritrovarono disoccupati e disperati. Tuttavia questa, fu in un certo senso, la loro...

MARTINETTI MECCANICI SERIE UP UP SERIES SCREW JACKS MECHANISCHE SPINDELHUBGETRIEBE DER SERIE UP Il martinetto meccanico permette di trasformare il movimento rotatorio fornito da un motore elettrico, pneumatico, idraulico o perfino manuale in un movimento lineare che consente di effettuare sollevamenti verticali in tiro, in spinta o posizionamenti orizzontali. The screw jack makes it possible to transform the rotary motion provided by an electric, pneumatic, or hydraulic motor or even a handwheel, into linear motion that allows push or pull vertical lifting and horizontal positioning. Ein mechanisches...

I carter della serie UP per le grandezze 2.5, 5, 10 e 25 sono realizzati in lega di alluminio e per le grandezze 50 e 100 in ghisa. Per quelli in lega d’alluminio è previsto un trattamento anti ossidante, mentre per quelli in ghisa una specifica verniciatura. For 2.5, 5, 10 and 25 sizes UP series housings are made of aluminium alloy; for the 50 and 100 sizes the housings are made of cast iron. The aluminium alloy housings receive an anti-oxidant treatment, while cast iron housings have a specific paint finish. Die Gehäuse der Serie UP bestehen bei den Baugrößen 2,5, 5, 10 und 25 aus einer Aluminiumlegierung...

CARICHI MASSIMI AMMESSI MAXIMUM PERMISSIBLE LOADS MAXIMAL ZULÄSSIGE BELASTUNGEN I martinetti sono progettati per sopportare sia in trazione che in compressione il carico nominale statico ammesso. Il carico ammesso dipende dal tipo di fissaggio del martinetto e dalla direzione del carico. The jacks are designed to withstand the nominal static load permitted in tension and compression. The permissible load depends on the type of jack mounting and the load direction. Die Spindelhubgetriebe sind so ausgelegt, dass sie sowohl bei Zug- als auch bei Druckbelastungen der zulässigen statischen Nennlast...

In fase di progettazione occorre fare attenzione alla corsa massima del martinetto rispettando gli extra-corsa di sicurezza. Non sono ammesse battute meccaniche che potrebbero danneggiare i componenti interni del martinetto. During the design stage, pay attention to the screw jack maximum stroke and comply with the safety overrun distances. Contact with mechanical limit stops that may damage internal components of the jack is not permitted. Bei der Planung muss besonders auf den maximalen Hub des Spindelhubgetriebes geachtet und der SicherheitsZusatzhub muss berücksichtigt werden. Mechanische...
