Cranes - Bridge and gantry cranes

This European standard specifies the safety requirements  for the bridge and gantry cranes. This standard is not applicable to runways and other supporting structures.
The standard deals with all significant hazards, hazardous situations and events relevant to bridge and gantry cranes, when used as intended and under conditions foreseen by the manufacturer (see clause 4).
The specific hazards due to potentially explosive atmospheres, underground work, ionizing radiation, and operation in electromagnetic fields beyond the range of EN 50082-2 are not covered by this standard. Also the additional loads due to mounting on a floating or tilting basement are not covered by this standard.
This standard includes requirements for the lifting of persons.
NOTE   The use of cranes for lifting of persons may be subject to specific national regulations.
This European Standard is applicable to bridge and gantry cranes which are manufactured after the date of approval by CEN of this standard.

Introduction
This document is a harmonized European Standard to provide one means for bridge and gantry
cranes to conform with the Essential Health and Safety Requirements of the Machinery Directive
98/37/EEC .
This European Standard is a type C standard as stated in EN 1070.
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 a B standard, 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.
Absolute safety of the crane cannot be ensured by design, as operation depends on the skills of the
operators, maintenance personnel and inspectors as well as on numerous technical parameters in the
crane or its environment which may have large scatter. Therefore selections provided by this standard
reflect only the state of the art at the time of writing.
As many hazards related to bridge and gantry cranes depend on the place and use of the crane, it is
assumed that the correct information has been exchanged between the manufacturer and user (as
suggested in the ISO 9374-1 and 5), e.g:
 Clearances
 Requirements concerning protection against hazardous environment
 Processed materials, such as potentially flammable or explosive material (e.g. coal, powder type
materials).

1 Scope
This European standard specifies the safety requirements for the bridge and gantry cranes. This
standard is not applicable to runways and other supporting structures.
The standard deals with all significant hazards, hazardous situations and events relevant to bridge
and gantry cranes, when used as intended and under conditions foreseen by the manufacturer (see
clause 4).
The specific hazards due to potentially explosive atmospheres, underground work, ionizing radiation,
and operation in electromagnetic fields beyond the range of EN 50082-2 are not covered by this
standard. Also the additional loads due to mounting on a floating or tilting basement are not covered
by this standard.
This standard includes requirements for the lifting of persons.
NOTE The use of cranes for lifting of persons may be subject to specific national regulations.
This European Standard is applicable to bridge and gantry cranes which are manufactured after the
date of approval by CEN of this standard.

Introduction
This European standard has been prepared to be a harmonised standard to provide one means for bridge and
gantry cranes to conform with the essential health and safety requirements of the Machinery Directive, as
mentioned in Annex ZA.

Absolute safety of cranes cannot be ensured by design alone, as their operation depends on the skill of
operators, maintenance personnel and inspectors as well as on the numerous technical parameters relating to
the crane and its operating environment, which may have large scatter.

As many of the hazards related to bridge and gantry cranes relate to their operating environment and use, it is
assumed in the preparation of this standard that all the relevant information relating to the use and operating
environment of the crane has been exchanged between the manufacturer and user (as recommended in ISO
9374, Parts 1 and 5), covering such issues as, for example:

 clearances;
 requirements concerning protection against hazardous environments;
 processed materials, such as potentially flammable or explosive material (e.g. coal, powder type
materials).

This standard is a type C standard as stated in EN ISO 12100-1

The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are
scope of this standard.

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.

prEN 15011:2007 (E)
1 Scope
This standard applies to bridge and gantry cranes mounted in a fixed position or free to travel either by way of
metallic wheels on rails or non-metallic wheels on flat runway or roadway surfaces. This standard is not
applicable to non-fixed load lifting attachments, erection and dismantling operations, runways and supporting
structures nor does it cover additional loads due to the mounting of cranes on a floating or tilting base.
This standard does not include requirements for the lifting of persons.
This standard gives requirements for all significant hazards, hazardous situations and events relevant to
bridge and gantry cranes when used as intended and under conditions foreseen by the manufacturer (see
clause 4).
The specific hazards due to potentially explosive atmospheres, ionising radiation and operation in
electromagnetic fields beyond the range of EN 61000-6-2 are not covered by this standard.
This standard is not applicable to bridge and gantry cranes manufactured before the date of it’s publication as
an EN.
