Abstract: A trailer system includes a first trailer module, having a plurality of wheels, a loading bed, and a primary loading bed connector for connecting to a loading bed of a further trailer module to form a combined rigid loading bed. The primary loading bed connector is arranged below an upper surface of the loading bed of the first trailer module. A first jack system includes a first jack cradle, which has a jack holder, and a jack accommodated in the jack holder. A primary cradle connector is connected to the primary loading bed connector of the first trailer module and therewith connects the first jack cradle to the first trailer module. The jack holder extends at least partly below the upper surface of the loading bed of the of the first trailer module.

Abstract: A system is used for lifting a heavy oversized structural element. At least two opposing lifts are placement adjacent opposing sides of the element. Each lift includes a base, a tower, an elevator, and an actuator. The tower extending vertically from the base, and the elevator is disposed on the tower. A support extends from the elevator outward from the tower to engage a point on the element. A guide of the elevator is configured to ride along a rail of the tower. The actuator is connected to the elevator and is configured to move with the elevator vertically along the tower. The actuator can include a strand jack disposed on the elevator. Hydraulic operation of the stand jack moves the jack and elevator along a strand extending along the tower. The arrangements of the lifts leave space below the raised element free for access to other operations.
