EN 12312-19:2005 (E)

Introduction
This document specifies health and safety requirements, as well as some functional and performance requirements
for aircraft jacks, axle jacks and hydraulic tail stanchions intended to be used for servicing and handling of all
aircraft types commonly in service in civil air transport.
The minimum essential criteria are considered to be of primary importance in providing safe, serviceable, economical,
and practical aircraft jacks, axle jacks and tail stanchions. Deviations from the recommended criteria should occur
only after careful consideration, extensive testing, risk assessment and in service evaluation have shown alternative
methods or conditions to be satisfactory.
This document is a Type C standard as stated in EN ISO 12100:2003.
The machinery concerned and the extent to which hazards, hazardous situations and events are covered are
indicated in the scope of this document.
When provisions of this Type C standard are different from those which are stated in Type A or B standards, the
provisions of this Type C standard take precedence over the provisions of the other standards, for machines that
have been designed and built according to the provisions of this Type C standard.

1 Scope
This document specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise
during the commissioning, operation and maintenance of aircraft jacks, axle jacks and hydraulic tail stanchions
when carried out in accordance with the specifications given by the manufacturer or his authorised representative.
It also takes into account some performance requirements recognised as essential by authorities, aircraft and
ground support equipment (GSE) manufacturers as well as airlines and handling agencies.
This document applies to:
 all types of aircraft jacks;
 axle jacks and hydraulic tail stanchions designed to be used at specific jacking points on the aircraft (examples
see Annex A).
NOTE A tail stanchion type is intended to be used with one type of aircraft.
This document does not apply to aircraft recovery equipment.
This document does not establish requirements for noise and vibration.
Noise and vibration are dealt with respectively in EN 1915-4 and EN 1915-3.
This Part of EN 12312 is not applicable to aircraft jacks, axle jacks and hydraulic tail stanchions which are
manufactured before the date of publication of this document by CEN.

4 List of hazards
The list of risks and hazards (see Annex B) is based on EN 1050 and contains the hazards and hazardous situa-
tions, as far as they are dealt with in this document, identified by risk assessment as significant for aircraft jacks,
axle jacks and hydraulic tail stanchions and which require action to eliminate or reduce risks.
5 Safety requirements and/or measures
5.1 General requirements
5.1.1 Aircraft jacks, axle jacks and hydraulic tail stanchions shall conform to the relevant requirements of
EN 1915-1, unless otherwise specified in this document. They shall also conform to the specific requirements of
this document.
5.1.2 Stability and strength calculations shall be carried out in accordance with EN 1915-2.
5.1.3 Where a pressure relief valve is used for overload protection, it shall not be positioned between the ram
and its control device. The pressure relief valve shall be adjusted to the lowest possible value but not exceeding
125 % of the rated load.
5.1.4 On jacks it shall be possible for the operator to control the lowering speed or stop the lowering at any load
up to the rated load, e.g. on manually operated jacks, by a finely controllable valve.
5.1.5 Maximum admissible forces for manual operation and translation of jacks and stanchions and the methods
to measure it are given in Annex C.
