Abstract

A maintenance vehicle for performing operations along an aerial ropeway of a mechanical lift installation consists of a car suspended on the rope by connecting means which comprise a top part fixed to the rope, a bottom part fixed to the car, articulation means of the top part with respect to the bottom part, adjustment means of the angle between the bottom part and top part up to an inclined position of the car with respect to the vertical, and means for securing car in the inclined position.

1 . A maintenance vehicle for performing operations along an aerial ropeway of a mechanical lift installation comprising a car suspended on the rope by connecting means comprising:
 a top part fixed to the rope,   a bottom part fixed to the car,   and articulation means of the top part with respect to the bottom part allowing relative swiveling, in a vertical plane parallel to the rope, of the top and bottom parts forming a variable angle between them,   
       wherein the connecting means on the one hand comprise adjustment means for adjusting the angle between the bottom part and the top part, up to an inclined position of the car with respect to the vertical, and on the other hand comprise means for securing the car in the inclined position. 
     
     
         2 . The vehicle according to  claim 1 , wherein the adjustment means comprise a cog-wheel fixed on the top part in a plane parallel to said vertical plane and operating in conjunction with an endless screw mounted rotating on the bottom part. 
     
     
         3 . The vehicle according to  claim 2 , wherein the endless screw is fixed to one end of a transmission shaft equipped at its opposite end with a crank positioned inside said car. 
     
     
         4 . The vehicle according to  claim 1 , wherein disengagement means are inserted between the articulation means and the adjustment means. 
     
     
         5 . The vehicle according to  claim 1 , wherein the bottom part comprises an articulated operating arm. 
     
     
         6 . The vehicle according to  claim 1 , wherein the car comprises at least one platform able to be moved by moving means between a retracted position where the platform is housed inside said car and an extended position where the platform is outside the car. 
     
     
         7 . The vehicle according to  claim 6 , wherein the moving means comprise a hinge with an axis parallel to the floor of the car. 
     
     
         8 . The vehicle according to  claim 7 , wherein the car comprises means for adjusting the height of the hinge with respect to the floor of the car. 
     
     
         9 . The vehicle according to  claim 7 , wherein the car is equipped with means for adjusting the incline of the floor of the platform with respect to the floor of the car, in the extended position. 
     
     
         10 . The vehicle according to  claim 6 , wherein the moving means comprise a sliding link in a direction included in a plane perpendicular to the floor of the car. 
     
     
         11 . The vehicle according to  claim 1 , wherein the car comprises an electricity generating set and/or an electric power supply battery and/or a lubrication unit.
