4. Functional description
4.1 Description
The spreaders have been designed in such a way that a hydraulically operated piston
activatesmechanicaljointssymmetricallytoopenorcloseasetoftwooppositespreader
arms.Thismovementcanbeusedtospreadopen,squeezeorpullopenobjects.
Foralldevices,themovementisactivatedbymeansofavalveintheformofastargrip.
Alldevicesguaranteethedeadman'sswitchandthefullload-supportingfunctionwhenthe
stargripisreleased.
HURSTeDRAULICdevicesdonotneedtobeconnectedtoanexternalhydraulicsource
(e.g.amotorpump).Generationoftherequiredhydraulicpressuretakesplacewithinthe
bodyofthedevice.
Eitherabatteryoranexternalpowersupplymustbeconnectedasanenergysource.
Youcanchoosewhichenergysourceyouwishtouse.Boththeaccumulatorbatteryand
themainspowerunitcanbeinsertedintotheopeningprovidedinthebodyofthetool.
Theyarethenautomaticallylockedintoposition.
YoucanextendtheoperatingtimeofyoureDRAULICdevicebyusingseveralbatteries.
Thebatteriescanberechargedafteruse,usingasuitableexternalcharger.
Ifyouaremakinguseofanexternalpowersupply,thedevicecanbeusedforanalmost
unlimitedtime.Thistimeisonlylimitedbytheexternalenergysourceandtheoverheating
switchofthepowersupply.
ToallowyoutoselectthebestpossibleenergysupplyforyoureDRAULICdevice,neither
thebatterynorthepowersupplyformpartofthedeliveryscope.Youwillndsuitablebat-
teriesandpowersuppliesintheHURSTaccessorieslist.
eDRAULICdevicescomewithstandardlightttingstofacilitateworkunderpoorlight
conditions.
Thelight-emittingdiodesattachedontheoperatingsidelightuptheworkarea.The
mainswitchhasalsobeenequippedwitharinglight,sothatyoucanimmediatelydetect
whetherthedeviceisswitchedonornot.Whenexchangingthebatteryorpowersupply,
theconnectionslotwilllightupforapproximately30seconds.
