Folding trailer with hydraulic lift system |
摘要 |
An improved folding trailer includes a base member supported by a pair of wheels with a top member movably connected to the base member. A plurality of extendable support units is mounted on the base member and can be hydraulically driven to extend the top member. The hydraulic system is connected to the extendable support units through pulleys and cables and includes a pressure-compensated flow control valve system for hydraulically limiting the retraction rate of these extendable support units.
