  • Patent number: 4459076
    Abstract: A machine for vertical transportation of goods from a packing line onto a pallet. The machine includes a vertically movable lifting device provided on a horizontally travelling wagon, the device being provided with lifting forks for receiving and lowering the pieces of packages. Counterweights are provided on the travelling wagon, the counterweights being connected to the lifting device by wires. The counterweights are heavier than the lifting device but the weight thereof is less than the total weight of the lifting device and the thereon loaded pieces of packages. The transmission comprises an endless loop, which is fixedly mounted to the lifting device, which is driven by a motor. During a cycle of operations the pieces of packages are fed from a packing line out onto the lifting forks of the machine until they abut a start impulse switch that starts the motor. Due to the weight of goods, the lifting forks are lowered until they are stopped by the pallet.
