Maintenance shuttle for an electric overhead conveyor

Abstract

A maintenance shuttle of modular design for an electric overhead conveyor with a rail system, with a running gear module as well as a maintenance basket module, wherein the running gear module and the maintenance basket module are designed in such a way that the running gear module can be mounted into the rail system of the electric overhead conveyor, the maintenance basket module can be coupled to and decoupled from the running gear module and, in the coupled state, provides protection against falling for an operator, and that the running gear module and the maintenance basket module can be assembled and disassembled at the operating site by an operator by means of manually lockable and releasable bolts.

What is claimed is: 
     
         1 . A maintenance shuttle of modular design for an electric overhead conveyor with a rail system, comprising:
 a) a running gear module as well as a maintenance basket module, wherein the running gear module and the maintenance basket module are designed in such a way that   b) the running gear module can be mounted into the rail system of the electric overhead conveyor,   c) the maintenance basket module can be coupled to and decoupled from the running gear module, and in the coupled state provides protection against falling for an operator, and that   d) the running gear module and the maintenance basket module can be assembled and disassembled at the operating site by an operator by means of manually lockable and releasable bolts.   
     
     
         2 . The maintenance shuttle according to patent  claim 1 , wherein the running gear module comprises at least two rollers and two guide rollers for each roller, wherein, for the installation of the maintenance shuttle on the rail system, one of the guide rollers each is designed in such a manner that it can be unlocked and swiveled out and/or swiveled in and locked. 
     
     
         3 . The maintenance shuttle according to  claim 1 , wherein the maintenance basket module can be coupled to the running gear module in such a way that a mounting height, which is depending on the size of the operator, can be achieved. 
     
     
         4 . The maintenance shuttle according to  claim 1 , further comprising a locking pin/cotter pin combination for coupling points between the running gear module and the maintenance basket module. 
     
     
         5 . The maintenance shuttle according to  claim 2 , wherein one of the at least two rollers can be driven manually by means of a crankshaft drive mechanism. 
     
     
         6 . The maintenance shuttle according to patent  claim 5 , wherein the manual crankshaft drive mechanism can be replaced or assisted by a battery-operated electric screwdriver.
