Hand truck
Hand trucks having a powered lifting assembly are disclosed. In certain aspects, hand trucks having a motor assembly and a battery pack mount arranged to removably receive a battery pack arranged for a portable tool are disclosed. Hand trucks having a pivoting rearward support are also disclosed, with particular arrangements advantageously pivoting the rearward support upwardly as it is configured into the retracted configuration so as to lift wheels of the rearward support above other wheels of the hand truck.
1. A hand truck, comprising:
a frame having a first end and a second end;
a wheel assembly attached to the first end of the frame and including at least two wheels;
a lifting platform moveable along a length of the frame between the first end and the second end;
a motor assembly arranged to move the lifting platform along the frame; and
a battery pack mount arranged to removably receive a separate battery pack arranged for a portable tool and transfer power from the battery pack to the motor assembly;
wherein the battery pack mount is not a portion of a hand drill; and
wherein the motor assembly is coupled to the lifting platform and travels with the lifting platform when the lifting platform moves along the frame.
2. The hand truck of claim 1 , wherein:
the battery pack mount is arranged to receive a battery pack adapted for a portable drill.
3. The hand truck of claim 2 , and further comprising a battery pack adapted for a portable drill, wherein at least one of the battery pack and the battery pack mount has a latch arranged to engage the other of the battery pack and the battery pack mount, the latch configured to selectively lock the battery pack to the battery pack mount.
4. The hand truck of claim 3 , wherein:
the battery pack mount is positioned on the motor assembly.
5. A hand truck, comprising:
a frame having a first end and a second end;
a wheel assembly attached to the first end of the frame and including at least two wheels;
a lifting platform moveable along a length of the frame between the first end and the second end;
a motor assembly arranged to move the lifting platform along the frame;
a battery pack mount arranged to removably receive a separate battery pack arranged for a portable tool and transfer power from the battery pack to the motor assembly;
a battery pack adapted for a portable drill, wherein at least one of the battery pack and the battery pack mount has a latch arranged to engage the other of the battery pack and the battery pack mount, the latch configured to selectively lock the battery pack to the battery pack mount; and
an elongated gearing system extending at least partially between the first end of the frame and the second end of the frame;
wherein the battery pack mount is arranged to receive a battery pack adapted for a portable drill;
wherein the battery pack mount is positioned on the motor assembly;
wherein the motor assembly is coupled to the lifting platform and travels with the lifting platform when the lifting platform moves along the frame;
wherein the motor assembly engages to the elongated gearing system to move the lifting platform along the frame; and
wherein the motor assembly includes a wireless communication module.
6. The hand truck of claim 1 , and further comprising a battery pack,
wherein at least one of the battery pack and the battery pack mount has a latch arranged to engage the other of the battery pack and the battery pack mount, the latch configured to selectively lock the battery pack to the battery pack mount.
7. The hand truck of claim 1 , wherein:
the battery pack mount is positioned on the motor assembly.
8. The hand truck of claim 1 , wherein:
the motor assembly is coupled to the lifting platform and travels with the lifting platform when the lifting platform moves along the frame.
9. The hand truck of claim 8 , comprising:
an elongated gearing system extending at least partially between the first end of the frame and the second end of the frame;
wherein the motor assembly engages to the elongated gearing system to move the lifting platform along the frame.
10. The hand truck of claim 1 , wherein:
the motor assembly includes a wireless communication module.
11. The hand truck of claim 1 , further comprising:
a rearward support configurable between an extended configuration and a retracted configuration and having a downward extending support leg; and
an intermediate member extending from the frame to the rearward support member and having a first end pivotably coupled to the frame and a second end pivotably coupled to the rearward support.
12. The hand truck of claim 11 , wherein:
the downward extending support leg is nested within a portion of the frame in the retracted configuration.
13. A hand truck, comprising:
a frame having a first end, a second end, a left frame member, a right frame member, and defining a plane;
a wheel assembly attached to the first end of the frame;
a lifting platform;
a rearward support configurable between an extended configuration and a retracted configuration and having a downward extending support leg; and
an intermediate member extending from the frame to the rearward support and having a first end pivotably coupled to the frame and a second end pivotably coupled to the rearward support;
wherein an upper portion of the downward extending support leg is pivotably attached to the frame such that a lower portion of the downward extending support leg pivots towards or away from the first end of the frame when the downward extending support leg is pivoted relative to the frame; and
wherein the upper portion of the downward extending support leg is closer to the second end of the frame in the retracted configuration than in the extended configuration.
14. The hand truck of claim 13 , wherein:
the downward extending support leg is in-plane with the frame in the retracted configuration.
15. The hand truck of claim 13 , wherein:
the downward extending support leg is nested within a portion of the frame in the retracted configuration.
16. The hand truck of claim 13 , comprising:
a locking member arranged to slidably lock the rearward support relative to the frame.
17. The hand truck of claim 13 , comprising:
a motor assembly arranged to move the lifting platform along the frame; and
a battery pack mount arranged to removably receive a battery pack arranged for a portable tool and transfer power from the battery pack to the motor assembly.
18. The hand truck of claim 1 , wherein:
the motor assembly includes a housing containing a motor; and
wherein the housing provides counterforce to the motor during operation so that no mechanical force external of the hand truck acting on the motor assembly is required for the motor assembly to move the lifting platform.
