Abstract
A dolly device for loading and unloading a container which comprises a control frame that pivots among a plurality of operational positions such that the control frame facilitates the loading or unloading of the container and supports the container while being transported from location to location.
Claims17
A dolly device for loading and unloading a container, comprising:
- a. a base having a lower portion supported by a plurality of roller devices;
- b. a support surface operably mounted relative to the base and having a plurality of friction reducing members configured to reduce the amount of friction between the support surface and a container moving on the support surface;
- c. a control frame mounted above the base and the support surface for pivoting between a plurality of operational positions for selectively limiting the movement of a container supported on the support surface;
- and
- d. a locking mechanism having a plurality of locking positions configured to selectively hold the control frame in a plurality of stop positions.
