Remote controlled overhead traveling crane, in particular for use

in hot cells

The invention relates to a remote-controlled overhead traveling crane to « Lifting and moving loads, especially for use in hot cells in old radioactive or dangerous atmospheres or in closed rooms, in which the crane requires a minimum of space have nut, with a crane bridge that moves on rails firmly connected to a fixed support component, and one on the crane bridge adjustable and liftable from this trolley, the drive elements for the hoist and owns the trolley.

Ls iöt already a remote-controlled overhead traveling crane of the kind mentioned at the beginning Ai t known who owns a detachable trolley. However, only the hoist and the trolley drive are on this arranged, so CaS can only be iaatandgeaetzt after lifting the trolley outside the hot cell. The crane drive is outside of the trolley movement path arranged on the crane bridge, which also means an increased Hatuubedarf results.

Ks is also known to be a traveling crane on its traveling catee in addition to the crane operator there is a damping force measuring device " which serves as a drive unit for all crane movements. This is for remote control in a cell or unsuitable for cramped liauae retention niases. The trolley is not removable.

Siesee Systea, however, would have suffered from Vaantell an over-assault the premonition of the gear, bsw. of the wave as a result of the Movement between the trolley and the crane bridge, while the two gear parts altelaaader are engaged. Is would result the risk of irregular transmission and the possibility of the rieamens. With these systems it would also be difficult to do without violent shocks when the trolley is set up again on the crane bridge or when you change them, bring about a perfect singing riff.

Crane travel drives are separate.

The lifting members consist of one between the walls 72 and 73 of the housing 71 arranged drum 75 * a main motor built into the drum and outside the walls of a KiTOiraotor 76 and a reduction gear 76a, whose drives through the walls 72 and 73 hinduroh by means of sealed connections take place. The frommt1, the rope guide and the roller piston are preferably made of stainless steel, which »I can easily disinfect by washing.

On the other side of the wall 74, the horizontal wall 77 which ends at approximately half the height of the housing, laterally to the Shaft 25 is extended towards, there is the drive unit with reduction gear for Kata and crane drive. Of the Trolley drive includes a Unterereetaung gear 73a, the Main motor 78b and an auxiliary motor 73c. The crane drive includes an auxiliary motor 79a, the main motor 79b, and a reduction gear 79c, at the end of which there is a Pig. 7 shown angle countershaft 30 is located. The sealing of the Geliaj.se 71 and the protection of the various drive organs extended outside the housing are provided by two lateral cages 81 and 82 and achieved by an upper plate 83. The trolley drive drives two rollers 13 of the trolley directly.

The determination of this position brought about using the auxiliary drives is carried out with the aid of indicator lamps attached to the control panel of the overhead crane, which light up when their circuit is closed by cams or control cams. This position is determined by the two mutually perpendicular directions corresponding to the Iran driving and cat driving movements. For example, the erection of the crane bridge 2 on the lifting axis is determined by a crouch carried by a bracket 98 firmly connected to the crane bridge and acting on a contact 99 attached to the support 11 (FIG. 1). Correspondingly, the position of the track 12 in relation to the cat travel movements is determined by another squat 100 firmly connected to the crane chassis gear (year 5).
