Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards

bodies (ISO member bodies). The work of preparing International Standards is normally carried out

through ISO technical committees. Each member body interested in a subject for which a technical

committee has been established has the right to be represented on that committee. International

organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of

electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are

described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of

any patent rights identified during the development of the document will be in the Introduction and/or

cranes and their supporting structures
1 Scope

This document specifies the inspections to be carried out on bridge and gantry cranes. It is intended to

be used in conjunction with ISO 9927-1.
It does not cover inspection prior to the first use of a bridge or gantry crane.

competent person

person who has the necessary practical and theoretical knowledge and the necessary experience of the

crane and equipment used in the lifting operation to carry out the function satisfactorily

Note 1 to entry: Some countries have legislation about the qualifications required for persons inspecting cranes.

4 General

In order to ensure safe operation of bridge and gantry cranes, their proper working and operational

condition shall be maintained. Therefore, all cranes need to undergo regular inspections. This ensures

that deviations from safe conditions are detected and can be rectified. The inspections shall be

arranged by the user.
The regular inspections are
— daily inspections,
— frequent inspections,

---------------------- Page: 5 ----------------------
ISO 9927-5:2017(E)
— periodic inspections, and
— exceptional inspections.

If the crane is to be used for lifting a person, an appropriate inspection and risk assessment should be

carried out before the lift is commenced.

The manufacturer’s instructions for inspection shall take precedence over the requirements of this

document.

Annex A gives an overview of the inspections (periodicity, content, persons in charge, results and

reports).
5 Daily inspections
5.1 General

Daily inspections shall be carried out at the start of each shift during which the crane is to be used. These

are to test the functionality of the crane and visually check for any defects (in general, no dismantling is

required). It is essential that these are carried out from a position of safety. Visual and auditory checks

are normally made from floor level unless a better permanent vantage point is available.

They shall be carried out by a competent person (e.g. the crane driver).
5.2 Content
The inspections shall include the following:
a) the functioning of emergency stop controls;
b) the functioning of all crane motion controls (generally without a load);
c) the functioning of electrical isolator switch;

d) the functioning of motion limiting devices, exercising caution while making checks in case of

malfunction;
e) the functioning of brakes (generally without a load);

f) the functioning of limiting and indicating devices and audible warning devices, where fitted;

g) a visual examination of the general condition of the crane structure and mechanisms, with

particular attention to the ropes, chains or belts, the sheaves, the hook and its latch;

h) any unusual noises or erratic movement during operation;

i) for cab-controlled cranes and cranes with access to the bridge, a visual examination to ensure

that the work areas on the crane are tidy and free from any item which might fall, that access and

egress from the cab is adequate and that the appropriate fire-fighting equipment is available and

serviceable;

j) a visual examination of the condition of the cab controls, the pendant and associated cables

or remote control station as appropriate; in particular, the condition of the casings and seals of

pendant and remote controls, as damage can lead to false commands;

k) where an intelligent self-diagnosis and fault-finding system is provided, checking any information

on the display;

l) a visual examination to ensure that there are no obstructions in the path of travel of the crane and

power feed system and that adequate precautions are in place to prevent collisions; in particular

for portal and semi-portal cranes, a check for any debris or other track obstructions;

m) a visual examination to ensure that the crane signage is present and legible including the rated

capacity, any individual hoist and hoist combination capacities and motion signage on crane/hoist

structures corresponding to the operator controls.

In respect of d) above, when it is impractical, due to speed or distance, to check long travel limiting

devices on every occasion, a check need only be made when the crane is to be used in their vicinity.

5.3 Results

Written records of all daily checks shall be kept and include at least the following information:

— identity of the crane;
— date of inspection;
— result of the check, i.e. whether or not the crane passed;
— name and signature of the person carrying out the check.

NOTE This can be kept to a minimum by, for example, completing a single line of a pro-forma record card

located near the crane.

Any defect found shall be reported to a person authorized and competent to decide on the action to take

(e.g. to leave the crane in use, repair it, make a more detailed inspection of a part of the crane or the

whole crane or, in the event that the crane is not safe to use, to isolate and lock-off the crane to prevent

further use until the problem has been resolved).

The crane record shall be updated with the result of the inspection and the action taken.

6 Frequent inspections
6.1 General

Frequent inspections shall comprise visual and auditory inspections as specified in 6.2, and the

functional tests according to 5.2.

NOTE In general, no dismantling is required, although it might be convenient to schedule the inspections

concurrently with planned preventive maintenance.

They shall be carried out by a competent person (e.g. an experienced technician; see ISO 9927-1).

6.2 Items to be inspected

In addition to any checks specified by the manufacturer, the following items, as summarized in Table 1,

shall be inspected:

a) all wire ropes for broken wires, flattening, basket distortion or other signs of damage, excessive

wear and surface corrosion in accordance with ISO 4309, other lifting media such as chain or

webbing belts for damage or excessive wear;

b) all rope, chain or belt terminations, pins and retaining devices, and inspection of all sheaves, for
