14. Safety when lifting and dumping
In compliance with standard EN 12525 + A2 2010, it can be disengaged for working when no one is near the load.
The movements can then be carried out, with no loss of power or speed of execution.
Uniquely, this equipment is compatible with the Shock Eliminator and the notched oating position.

14.1 Extract from the Front Loaders standard EN12525 + A2 2010:
"4.4.4 Protection against unintentional lowering
If the front loader is also designed for lifting operations requiring the presence of someone near the load when the loader
is in raised position, the hydraulic circuit of the lifting arm rams must, in compliance with Annex E, be tted with a safety
device to prevent accidental lowering of the lifting arm. This device must remain active in the event of a failure of the
control circuit's power supply.
If this safety device can be switched on/o󰀨 or activated/deactivated for operations that do not require the presence of
someone near the load, then the following additional specications apply:
— it must be possible to switch on/o󰀨 or activate/deactivate the safety device from the driving position;
— it must be possible to switch on or activate the safety device from the ground without being close to the load;
— the operating device to switch o󰀨 or deactivate the safety device must be designed and located so that the operator
cannot operate it unintentionally;
— the status (on/o󰀨 or activated/deactivated) of the safety device must be clearly indicated and clearly visible from the
driving position and from the loading area.
In compliance with 7.1.2, the correct operating method, along with appropriate warnings, must be explained in the
instruction manual.
The loader must be tted with a warning stating that for lifting operations requiring the presence of someone near the
load, the safety device must be switched on (activated) when the loader is in the raised position (see 7.2).
Information on the use of front loaders that are not designed for lifting operations requiring the presence of an operator
near the load when the loader is in raised position must comply with 7.1.4 and 7.2. “
” Annex E (normative)
Test method and acceptance criteria for means of avoiding unintentional lowering
E.1 Terms and denitions
E.1.1
discharge device
hydraulic valve(s) used to simulate a break in the loader's hydraulic lines.
E.1.2
test load
weight (50 ± 10)% of nominal lifting capacity specied by the manufacturer of the loader.
E.2 Test procedure
The test specied from E.2.1 to E.2.2 must be carried out according to each of the following conditions:
— position held after lowering the test load to a height of (1 ± 0.1) m (static test);
— position held after lifting the test load to a height of (1 ± 0.1) m (static test);
and at hydraulic system oil temperatures of between 40°C and 50°C.
E.2.1 The discharge device between the lifting rams and the control valve must be open
E.2.2 The total downward movement of the load must be measured at the implement's pivot point
E.3 Acceptance criterion
The total downward movement measured in E.2.2, during the rst 10 seconds, must not exceed:
— 100 mm, if the safety device is switched o󰀨 or manually deactivated;
— 300 mm, if the safety device is permanently activated.
After 5 min, additional downward movement must not exceed 100 mm. "
