This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 147.

This draft amendment A2, if approved, will modify the European Standard EN 12999:2011+A1:2012. If this draft becomes an amendment,
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of this
amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other language made
by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC Management Centre has

Add to read: "a power driven attachment for a chassis" and delete "powered crane"

Add into same sentence after "…to the top of the column," "designed to be" and delete "usually"

Add to NOTE 1, after "….installed on" : " another type of vehicle or on a"

Amend new para 3.1.21 to read :

and then renumber all the definitions (3.1.22 – 3.1.45):
3.1.22
load holding valve
valve which is normally closed and is opened by an external force to enable flow of fluid out of a
h ydraulic actuator
to
3.1.45
total lifting moment
sum of net lifting moment and the moment produced by dead loads

Add new sentence to read: "For load combinations A2 and B2, the value of φ shall be 0.95."
5.2.2.2   Hoisting and gravity effects of the gross load
Add following figure:
Add figure title: "Figure 2: Dynamic effect when hoisting a load

Change in Table 2a to read:

Change in Table 2b after "Type of " : insert "control system" and delete "hoist drive"
Change in description of HD1, HD4 and HD5 to read as follows:
HD1 is when the lifting movement can only be operated at a fixed speed, e.g. simple on- off
control;
HD4 is when the start of the lifting movement is performed with continuously increasing speed,
e.g. proportional spool valve by electrical or manual control;

HD5 is when the step-less control automatically ensures that the dynamic factor ϕ does not
exceed ϕ e.g. electronically controlled proportional pressure compensated spool

Add to first paragraph first sentence after ".for hoses shall" : "in general"
Add to first paragraph a new sentence:
" For HD5 drives, burst pressure for hoses shall be minimum 3.5 times the maximum working

Change second paragraph c) : delete "or" and change to "and"

5.6.1  General
5.6.1.8
Add after first sentence a second sentence:

"In this case it is essential that the rated capacity limiter reacts quickly enough in all working boom
positions, in particular at high boom angles, where the lifting radius could increase very rapidly."

Add new subclause:
"5.6.5.3  Inclination limiter for timber handling cranes"
"Timber handling cranes may be equipped with a device, measuring increased inclination of the
crane base due to load moment and stopping all crane movements, which need pump pressure,
when the inclination reaches the predetermined maximum

Note: this device should not be confused with an inclination sensing device which may be
incorporated into the rated capacity limiter of a loader crane not being a timber handling crane."
