摘要： 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. Then the motor pulls the travelling wagon backwardly. In a rear position, the motor is reversed by a switch. Then, the lifting device provided with the lifting forks is drawn upwardly by the counterweights until it reaches a mechanical stop. The motor continues to be in operation and pulls the travelling wagon forwardly until it reaches a terminal position switch that stops the cycle of operations. The cycle of operations is repeated until the pallet has been loaded up to a desired level.
