PCT No. PCT/SE80/00109 Sec. 371 Date Dec. 20, 1980 Sec. 102(e) Date Nov. 20, 1980 PCT Filed Apr. 17, 1980 PCT Pub. No. WO80/02277 PCT Pub. Date Oct. 30, 1980.When building, particularly private houses, it is necessary to convey goods such as roof tiles up to the roof. Conveyors have been produced which are of fixed shape, heavy and inconvenient to transport. The present invention presents a conveyor which is light and takes up little space when being transported. The conveyor consists of a central unit (I) comprising a telescopic tube which can be collapsed during transportation and pulled out to its full length for operation. The central unit is provided at each end with two transverse units (3L, 1A) over which two parallel belts (1E) are placed, said belts being preferably of nylon and being provided with a number of pushers (3H) arranged one after the other. A synchronization means (3A-D FIG. 2) is provided to align the pushers on the two belts at the same transverse level. |
