Lifting and transport device
A device is operable to lift and transport a pipe at a worksite. The device includes a base, a mast coupled to the base, and a carriage coupled to the mast upon which the pipe is supportable. The device further includes a lifting assembly that is operable to move the mast and the carriage in a first direction to a desired elevation relative to the base and a positioning assembly that is operable to move the carriage relative to the mast in a second direction that is transverse to the first direction.
1. A device configured to lift and transport a pipe at a worksite, the device comprising:
a base;
a mast coupled to the base;
a carriage coupled to the mast upon which the pipe is supportable, the carriage including an arm defining a recess in which the pipe is receivable;
a lifting assembly configured to move the mast and the carriage in a first direction to a desired elevation relative to the base; and
a positioning assembly configured to move the carriage relative to the mast in a second direction that is transverse to the first direction, the positioning assembly including an actuator configured to adjust the arm between a first position, in which the recess is oriented downward, and a second position, in which the recess is oriented upward.
2. The device of claim 1 , wherein the actuator is further configured to adjust the arm to a third position, in which recess extends in a lateral direction.
3. The device of claim 1 , wherein the actuator is a rotary shaft configured to receive torque from the second electric motor, causing the rotary shaft to rotate the arm, in which the pipe is received, between the first and second positions.
4. The device of claim 3 , further comprising a winch driven by the second electric motor, wherein the winch includes the cable wound around the rotary shaft, and wherein the second electric motor is configured to alternately wind and unwind the cable to rotate the rotary shaft.
5. The device of claim 3 , wherein the arm is a first arm coupled to a first end of the rotary shaft, wherein the carriage further includes a second arm coupled to an opposite, second end of the rotary shaft, and wherein the second arm includes a recess that is rotationally aligned with the recess of the first arm to support the pipe therein.
6. The device of claim 5 , wherein the base includes parallel first and second frame rails, wherein the pipe is supportable upon the first and second frame rails prior to being received within the recesses of the first and second arms, respectively, wherein the cable wound around the spool is attachable to the pipe while supported upon the first and second frame rails, and wherein the spool is configured to retract the cable, thereby pulling the pipe along the first and second frame rails toward the recesses of the first and second arms, in response to activation of the second electric motor.
7. The device of claim 6 , wherein the base includes first and second ramps transitioning the first and second frame rails, respectively, to a surface of the worksite.
8. The device of claim 1 , wherein the carriage includes a first carriage portion coupled to the mast and a second carriage portion that is movable relative to the first portion in the second direction, wherein the actuator is a first actuator, and wherein the positioning assembly includes a second actuator configured to adjust the second carriage portion between a retracted position, in which the second carriage portion is proximate the mast, and an extended position, in which the second carriage portion is located farther from the mast.
9. The device of claim 8 , wherein the second actuator is a linear actuator having a first end mounted to the first carriage portion and a second end mounted to the second carriage portion.
10. The device of claim 8 , wherein the battery pack provides electrical power to the second actuator.
11. The device of claim 8 , further comprising a remote control including
a first user control configured to activate the first electric motor and move the mast and carriage in the first direction,
a second user control configured to activate the second electric motor and rotate the second actuator, thereby rotating the arm with the pipe received therein, between the first and second positions, and
a third user control configured to activate the second actuator and move the second carriage portion between the retracted position and the extended position.
