An egg conveyor for a poultry plant includes a chain of the closed-loop type with bars, for conveying eggs from one or more laying hen sheds to a collection location, assemblies for traction along the chain which are provided with a motor drive component, and a control unit for synchronization of the traction assemblies. The motor drive components each include at least one gearmotor provided at least with a corresponding servomotor. The method for synchronization of traction assemblies in the conveyor includes the following steps: detecting continuously and instantaneously the angular position and the number of bars at each traction assembly, and calculating continuously and instantaneously the average of all the torques at the traction assemblies and, if the number of bars is different from a set number, correcting the speed of each servomotor to obtain a constant torque on each traction assembly, which corresponds to the average.

A lifting and lowering transportation device is capable of transporting articles between different delivery positions using transportation units, each including a lifting and lowering platform, a linear motor, and a chain. The lifting and lowering platform can pass through the delivery positions by moving along the circumferential track that is common to the transportation units. The linear motor generates the driving force to move the lifting and lowering platform along the circumferential track. The chain is loop-shaped and can circulate along the circulation track corresponding to the circumference path, and the linear motor moves the lifting and lowering platform by circulating the chain by the driving force generated by the linear motor. The circulation of the chain in each transportation unit is controlled independently of the other transportation units.
