  • Patent number: 9845646
    Abstract: A pipe handler trailer assists with the handling of very large and heavy pipes that are regularly raised to and lowered from an elevated surfaces. A height adjustment assembly sets the maximum height that a skidway will reach when a lift cylinder is fully extended and lift arms are thereby rotated. Located within lift arms are toothed racks. An adjustment block couples the skidway to lift arms through the racks and also supports locking blocks that have teeth complementary to the teeth on the racks. A lock will vary from firm contact with the inner wall of lift arms to having a gap there between. When the lock engages the inner wall of the lift arm this drives the complementary teeth into secure engagement with the rack teeth, which can then rigidly support heavy load without motion.
