GEDORE 1.04 HIGH POWER The power pack Reinforced cross-beam - the additional arching at the top of the crossbar produces an H-profile which in turn raises the load capacity as against the flexural torque. In the HP version the cross-beam is additionally hardened and tempered. This brings about practically a doubling of the loading limit The all-in steel legs are hot forged in one piece from 31CrV3 steel and hardened tempered. They provide a positive-locking connection to the cross-beam. The leg brake secures the hooks from unintentional motions. Pressing the release button unlatches the locking - the leg can be moved on the cross-beam. Releasing the button causes the leg to jam tight on the cross-beam with slipping ruled out. The permanently lasered scale makes it easier to symmetrically align the legs. This effectively stops any tilting when extracting caused by incorrectly positioned legs. A final marking specifies the maximum clamping spread. a Safety-relevant Forces amounting to several tons in weight act on the puller during the extracting operation Drop-forged components "announce" possible overloading by bending. This is due to the fibre course of the material during forging permitting a certain flexibility of the components ahead of fracturing - an extremely "healthy" property in fact Hydraulic spindles Hydraulic spindles simplify the work - less force and time needed for a pulling operation The hydraulic spindle principle is both straightforward and ingenious at the same time. The effect of screwing in the clamping bolt is to compress the grease inside the hydraulic piston - the extending piston acts on the part to be extracted with a force many times greater than that manually applied at the top. This controlled operation provides for working safely with the hydraulic spindle and is recommended in particular for high levels of force. In the 1.04 series a hydraulic spindle can be used upwards of puller size 2A. The pressure piece can be replaced by a tip and lengthened by 3585 or 135 mm. The small pressure spindle is secured with an unscrewing lock to stop any accidental withdrawal. 418
