摘要:
According to one aspect of the invention there is provided a mobile lifting assembly comprising a body frame with one or more wheels for transporting a structural member, and four individually controllable lifting devices connected to the body frame for repositioning (such as raising, lowering, tilting or rolling) of the structural member. According to another aspect of the invention there is provided a mobile lifting assembly comprising a body frame being adapted to locate on a supporting surface, a lifting device connected to the body frame for raising or lowering a structural member, and a skid resting on the supporting surface underneath the body frame and being arranged to contact the body frame to distribute forces imparted by the structural member on the body frame across the supporting surface.
摘要:
A transportation and installation assist device (16) for at least one precast concrete tilt panel. The panel(s) (18) are generally rectangular and have a first shorter end (44) with at least one lifting anchor therein, a second opposed shorter end (48) and a longitudinal axis (50) therebetween. The device (16) includes at least one frame (20) adapted to releasably engage an associated one of the panel(s) (18) substantially adjacent the second end (48) and support the panel (18) in a loading/transport orientation with the face of the associated panel (18) substantially vertical and the axis(es) (50) substantially horizontal. The frame (20) is also adapted for pivotal mounting to a table bed (14) of a truck (10) or trailer (12). The frame (20) and associated panel (18) pivot together when the first panel end (44) is lifted above the second panel end (48) until the associated panel (18) is in a releasing orientation with the face of the panel (18) substantially vertical and the axis (50) substantially vertical. Further lifting of the first panel end (44) releases the panel (18) from the frame (20).
