Abstract
A highly flexible unloading device, adapted for use with a truck having a lift mechanism, lifts coils of wire from hard to approach positions. A stationary boom extends from the truck's lift mechanism to a junction member. The junction member, operably connected to the stationary boom, can be rotated in a vertical plane by a first motor means. A rotatable boom operably connected to the junction member can be rotated in a horizontal plane by a second motor means. Being operably connected to the vertically rotatable junction member, the rotatable boom also rotates in the vertical plane. The rotatable boom has a ram member extendable therefrom by a third motor means.
Claims3
An unloading apparatus for use with a truck, said apparatus including:
- a stationary member having two ends with one of said ends being spaced from the truck;
- means connecting the other of said ends to the truck;
- a junction member;
- a first connecting means operably connecting said spaced end of said stationary member to said junction member;
- a first rotating means forming a part of said first connecting means, whereby said junction member can be rotated relative to said stationary member;
- a rotatable member;
- a second connecting means operably connecting said rotatable member to said junction member and including a sleeve having two ends with one of said ends fixed to the junction member, a threaded portion on the other end of said sleeve, said threaded portion extending into said rotatable member, a nut screwed on said threaded portion, means on said rotatable member engaged by said nut whereby the sleeve is operably connected to said rotatable member;
- and
- a second rotating means forming a part of said second connecting means, whereby said rotatable member can be rotated relative to said junction member.
An unloading apparatus for use with a truck, said apparatus including:
- a stationary boom having two ends with one of said ends being spaced from the truck;
- coupling means connecting the other end of said stationary boom to the truck;
- a first rotating means operably connected with said stationary boom;
- a first connecting means including a first shaft, said first shaft being rotated by said first rotating means and having an end projecting from said spaced end of said stationary boom;
- a junction member connected to said projecting shaft end whereby rotational movement of the shaft is transmitted to said junction member;
- a second rotating means operably connected with said junction member;
- a second connecting means including a second shaft, said second shaft being rotated by said second rotating means and having an end projecting from said junction member;
- a rotatable member;
- a sleeve having two ends with one of said ends fixed to the junction member;
- a threaded portion at the other end of said sleeve, said threaded portion extending into said rotatable member;
- a nut screwed on said threaded portion of said sleeve;
- and
- means on said rotatable member engaged by said nut whereby said sleeve is operably connected to said rotatable member.
