2.7. LHV Load holding valves
All cylinders are equipped with load-holding valves as a
safety device. After a crane movement, they hold the crane
in position, also in the unlikely event of a burst hose.
If there is a leak or a component fractures, such as a
pipe, hose or coupling, the load-holding valves will stop
the booms from collapsing down, even when the hydraulic
system is switched off, and you operate a particular crane
lever.
To operate a hydraulic cylinder equipped with a load
holding valve, an opening pressure is required.
DANGER
It is not permitted to manipulate these devices because you can cause serious
accidents.
Only an authorised service workshop can do the servicing, replacement and/or
repair of these valves.
2.8. Description of the crane
The loader cranes EFFER 265-315-395-525 are compact, fully hydraulically operated goods
cranes and fulfil the European Machinery Directive requirements specified in the standard EN
12999.
Stress class HC1-S1-HD5 according to EN 12999.
Maximum lifting capacity:
• EFFER 265 = 24.74 tonne metres
• EFFER 315 = 28.96 tonne metres
• EFFER 395 = 35.20 tonne metres
• EFFER 525 = 47.17 tonne metres
The crane is supplied in many versions from:
• EFFER 265-2S (reach 8.07 metres) to EFFER 265-6S (reach 16.95 metres)
• EFFER 265-C2S (reach 7.35 metres) to EFFER 265-C4S (reach 11.65 metres)
• EFFER 315-3S (reach 10.43 metres) to EFFER 315-8S (reach 21.27 metres)
• EFFER 315-C3S (reach 9.93 metres) to EFFER 315-C4S (reach 12.19 metres)
• EFFER 395-3S (reach 10.33 metres) to EFFER 395-8S (reach 21.37 metres)

• EFFER 525-3S (reach 10.21 metres) to EFFER 525-8S (reach 21.59 metres)
The designation "C" means that it is the short version of the 2nd boom.
The control valve DANFOSS, the controller (STEADY or SCANRECO) and the Progress 2.0 safety
system are standard equipment on this model.
