Abstract
The safety of a load carrying device has been enhanced by providing interactive mechanisms to ascertain the operations in predetermined manner. The enhanced safety mechanisms interactively force the operator to ascertain safety while an object such as a battery is loaded onto or unloaded from a predetermined structure such an industrial vehicle. The carrying device is engaged with the industrial vehicle during the loading or unloading task. In addition, the object is locked during the transportation. These safety features are mechanically ascertained.
Claims64
A safety device for carrying a load to a predetermined structure, comprising:
- a load carrying unit for holding the load;
- an engagement control located on said load carrying unit for engaging said load carrying unit with the predetermined structure in an engaged state and for disengaging said load carrying unit from the predetermined structure in a disengaged state;
- and
- a load control located on said load carrying unit for locking the load on said load carrying unit in a load lock state, said load control unlocking the load on said load carrying unit in a load unlock state, said engagement control in the engaged state allowing said load control to transition into the load unlock state from the load lock state, said engagement control in the disengaged state prohibiting said load control from transitioning into the load unlock state from the load lock state.

A safety device for carrying a load to a predetermined structure, comprising:
- a load carrying unit for holding the load;
- an engagement control located on said load carrying unit for engaging said load carrying unit with the predetermined structure in an engaged state and for disengaging said load carrying unit from the predetermined structure in a disengaged state;
- and
- a load control located on said load carrying unit for locking the load on said load carrying unit in a load lock state, said load control unlocking the load on said load carrying unit in a load unlock state, said load control in the load lock state allowing said engagement control to transition into the disengaged state from the engaged state, said load control in the load unlock state prohibiting said engagement control from transitioning into the disengaged state from the engaged state.

A method of operating a safety device for carrying a load, comprising the steps of:
- a) engaging a load carrying unit with a predetermined structure so that an engagement control to be in an engaged state;
- b) placing a load control in a load unlock state while the engagement control is in the engaged state;
- c) performing a predetermined task with respect to the load;
- d) preventing the engagement control from transitioning to the disengaged state from the engaged state during said steps b) and c);
- e) placing the load control in a load lock state upon completing said step c) while the engagement control is still in the engaged state;
- and
- f) disengaging the load carrying unit from the predetermined structure so that the engagement control is in a disengaged state only after said step e).
