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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent rights
in respect thereof. As of the date of publication of this document, ISO had not received notice of (a) patent(s)
which may be required to implement this document. However, implementers are cautioned that this may not
represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
Mobile crane operators frequently transfer from one crane to another of different model or manufacturer. This
document establishes a consistent arrangement and movement for the basic controls used during the crane-
operating cycle, to reduce operator confusion or incorrect control in an emergency. Some cranes may not be
equipped with all functions shown in the figures of this document.

Part 2:
Basic arrangement and requirements for mobile cranes
1 Scope
This document establishes the arrangement, requirements and direction of movement of the basic controls
for slewing, load lifting and lowering, and boom luffing and telescoping, on mobile cranes as defined in
ISO 4306--2. It deals with bi-directional controls and the basic arrangement and requirements for cross-shift
levers (multi-directional controls). It is intended to be used in conjunction with ISO 7752-1.

4 General requirements
The basic control arrangement of a mobile crane and the direction of movement of the controls shall not differ
from those specified in 5Clause 5 through 8Clause 8,, to avoid the operator's confusion and physical
interference when operating different cranes. Some cranes may not be equipped with all functions shown.
Other arrangements for control devices may be chosen due to the nature and work of the machine, provided
the same directions of movement of this document are followed.
a) a) The basic controls used during the crane operating cycle (see Figures 1Figures 1 to 77)) shall
be located within easy reach of the operator while he/she is at his station.
b) b) For controls with multiple functions assigned by a switch, an indicator is required to display
the selected function.
c) c) Means shall be provided to prevent the same function from being available on different levers
at the same time.
d) d) Hoisting 1 and hoisting 2 (see Figures 6Figures 6 and 77)) refer to primary and secondary
movements of the winches. The primary hoisting should always be on the right hand side, regardless of
the individual winch used.
e) e) Hand levers and foot pedals shall be provided with a means for holding the control in the
neutral position without the use of positive holding devices. They shall return to the neutral position
automatically upon release by the operator.
f) f) The required control operating forces shall be consistent with ISO 7752-1.
g) g) The required control operating distances shall be consistent with ISO 7752-1.
h) h) To minimize operator fatigue, ergonomic control design and positioning shall be consistent
with ISO 7752-1.
i) i) To ensure visibility of selections when operating in the dark, the selectors switches shall either
be illuminated, or cabin lighting shall be easily reachable to check settings.

5.2 Direction of movement
5.2.1 Slewing control — Hand lever 1
Push the lever forward to slew towards the boom:
— — slew left (operator's position on right side);
— — slew right (operator's position on left side or centre of crane).
Centre the lever to release the slewing power.
Pull back the lever to reverse direction.
5.2.2 Hoisting control — Hand lever 2 and foot pedal 6, hand lever 3 and foot pedal 7
Pull the lever back to lift the load.
Centre the lever to release the power and to hold the load (if equipped with an automatic brake) or to control
the load by depressing the brake pedal.
Push the lever forward to lower the load.
5.2.3 Boom luffing control — Hand lever 4
Pull the lever back to raise the boom.
Centre the lever to hold the boom in position.
Push the lever forward to lower the boom.
5.2.4 Fly jib luffing control — Hand lever 5
Pull the lever back to raise the fly jib.
Centre lever to hold the fly jib in position.
Push the lever forward to lower the fly jib.
5.3 Boom luffing control — Alternative arrangement (foot pedal operation)
The basic controls shall be arranged as shown in Figure 3Figure 3.
