<h2 id="requirements">Requirements </h2>

Functional requirements

Crank effort: in respect of the ergonomic operation, the crank effort shall not exceed 225 N.
Corrosion protection: the standard specifies the resistance to corrosion requirements of the surface treatment requested by the client.

Safety requirements

Mechanism: the rest position of the crank must not generate mechanical risks.

Overtravel: the mechanical assembly must withstand, at end of travel, an excess load on the crank equal to 150% of the maximum crank effort experienced at the rated dynamic load capacity.

Vertical static load capacity: the vertical static load capacity, as declared by the Manufacturer, cannot exceed 50% of the vertical static mechanical strength of the jack, measured experimentally.

Static side load capacity: the static side load capacity, as declared by the manufacturer, shall not exceed 50% of the static mechanical lateral strenght of the jack, measured experimentally by applying the load from any lateral direction.

Ground pressure: with the exception of jacks equipped with wheel or other base configurations intended for specific use on special surfaces, the average ground contact pressure must be lower than 760 kPa.

Prevention of accidental ground contact: l'the jack must be installed in such a way that, when not in use, accidental contact or sticking into the ground are not possible.

Security in operating position: in the case of mobile jack installation, there must be security systems for locking operating position and permitting operation.

Hydraulically operated jack safety: the safety requirements for compliance with ISO 4413 must be fulfilled. In particular, a load maintenance system (e.g. block valve) must be installed.


Reliability requirements

Vertical dynamic load capacity and service life: the vertical dynamic load capacity, as declared by the Manufacturer, cannot exceed the value declared for the vertical static load capacity, and must be verified experimentally by passing the dynamic reliability test (performance of at least 250 dynamic cycles, observing the maximum effort at the handle indicated by the standards and applying the envisaged load).



<h2 id="mark">Marking</h2>

The standard lists the information needed for marking the jack:

  • Manufacturer identification;
  • Product code (jack type) and production batch identification;
  • Vertical static load capacity;
  • Vertical dynamic load capacity;
  • Hydraulic fluid type (in the case of hydraulically operated jack);
  • Static side torsional resistance class (in the case that the fitting point is specified).
