Equipment to transfer load between a sliding receptor and a supporting structure comprising a withdrawable upper chassis comprising: - means for load lifting and lateral moving, the load being a container, the load lifting means consisting in a lifting system comprising front side connectors and rear side connectors, both comprising connection pins intended for connection with the corners of a container; - the lateral moving means consisting in a transfer system; and - a laser system for position identification of the withdrawable upper chassis; wherein: - the transfer system comprises: - a rigid frame steel structure comprising vertical sliding frames; - groups of hydraulic jacks placed within the rigid frame steel structure configured to lift the lifting system; and - wheels used as sliding means to slide the transfer system to the sliding receptor in a direction transversal to the direction of the container; - the lifting system: - is a steel frame mounted on the sliding frame and is configured to travel vertically along the sliding frame by means of the groups of hydraulic jacks; - the rear side connectors are mounted with a vertical shaft on a hinge plate and comprise a rotational plate configured to rotate up to 90° horizontally relative to the hinge plate, thereby enabling connection of the rear side connectors to the container via the connection pins; and - the front side connectors comprise a fork-shaped metal plate which has two articulated connections at each end connected to the lifting system and is configured to rotate from an inclined outward position to a vertical position by means of the connection jacks, thereby enabling connection to the container via the connection pins. - means for load lifting and lateral moving, the load being a container, the load lifting means consisting in a lifting system comprising front side connectors and rear side connectors, both comprising connection pins intended for connection with the corners of a container; - the lateral moving means consisting in a transfer system; and - a laser system for position identification of the withdrawable upper chassis; - the transfer system comprises: - a rigid frame steel structure comprising vertical sliding frames; - groups of hydraulic jacks placed within the rigid frame steel structure configured to lift the lifting system; and - wheels used as sliding means to slide the transfer system to the sliding receptor in a direction transversal to the direction of the container; - a rigid frame steel structure comprising vertical sliding frames; - groups of hydraulic jacks placed within the rigid frame steel structure configured to lift the lifting system; and - wheels used as sliding means to slide the transfer system to the sliding receptor in a direction transversal to the direction of the container; - the lifting system: - is a steel frame mounted on the sliding frame and is configured to travel vertically along the sliding frame by means of the groups of hydraulic jacks; - is a steel frame mounted on the sliding frame and is configured to travel vertically along the sliding frame by means of the groups of hydraulic jacks; - the rear side connectors are mounted with a vertical shaft on a hinge plate and comprise a rotational plate configured to rotate up to 90° horizontally relative to the hinge plate, thereby enabling connection of the rear side connectors to the container via the connection pins; and - the front side connectors comprise a fork-shaped metal plate which has two articulated connections at each end connected to the lifting system and is configured to rotate from an inclined outward position to a vertical position by means of the connection jacks, thereby enabling connection to the container via the connection pins.
