Patent number: 9817396Abstract: An unmanned aerial vehicle (UAV) is disclosed that may allow for supervisory control interaction by a remote operator to assist with navigation to a target location. The UAV may navigate to a target area and capture and send an image of the target area to the remote operator. The remote operator can then provide a user input that indicates a target location within the target area. Upon receiving an indication of the target area, the UAV can then autonomously navigate to the target location. In some examples, after reaching the target location, the UAV may initiate delivery of a payload at the target location using a retractable delivery system while the UAV hovers above.Type: GrantFiled: December 31, 2014Date of Patent: November 14, 2017Assignee: X Development LLCInventors: Leila Takayama, Brandon Alexander, Roger William Graves, Justin Sadowski, Abraham Bachrach

Publication number: 20120261372Abstract: A material dumping system is suspendable by a single hoist line. A first hoist line pulley is attached to a forward attachment element on a dumping container so that the line can be wrapped under the first pulley to support the container. The hoist line extends from under the first pulley to a second pulley attachable to the hoist's support structure where it is wrapped over the second pulley to extend therefrom to a rearward attachment element on the dumping container. A selectively actuated hoist line brake permits rotation of both pulleys during normal raising and lowering of the dumping container with the container in a horizontal attitude. However, when it is desired to dump the contents of the container, the hoist line brake is actuated to prevent rotation of the second pulley while permitting rotation of the first pulley. The hoist line is then extended to tilt the container forward for dumping purposes.Type: ApplicationFiled: April 13, 2011Publication date: October 18, 2012Applicant: ALLIED POWER PRODUCTS, INC.Inventor: Robert L.

Patent number: 6517131Abstract: A unit (10) having a boom (12) and rotary device (14). The rotary device includes a first bracket (22), a second bracket (24) movably mounted to the first bracket and a third bracket (54) connected to the second bracket by a driven shaft (34). A motor (40) is mounted on a motor bracket (38) mounted to the second bracket. A drive gear (46) is mounted on the motor and engages a driven gear (48) mounted on the driven shaft. A friction plate (56) is located on the driven shaft adjacent the third bracket. When a load (102) is connected to the third bracket, the weight of the load pulls the third bracket downward into contact with the friction plate. The frictional contact between the third bracket and the friction plate causes the third bracket and the load to rotate when the drive shaft is rotated.Type: GrantFiled: August 17, 2001Date of Patent: February 11, 2003Inventor: Thomas Haataja

Patent number: 5100278Abstract: An improved locomotive crane boom generally indicated at 10 has of a first member 11, second member 12, and third member 13 each pivotally connected at various pivot points to one another and to locomotive crane 14. A series of pistons and cylinders, 19, 20 and 21, powered by hydraulic pump 23 and fluid source 34, may be selectively extracted or retracted thereby permitting the improved boom to be positioned at any point along the length of a typical gondola car 17 to be unloaded. In operation, locomotive crane 14 with the included improved boom 10 does not need to be uncoupled from gondola car 17 for unloading since the improved boom may be articulated such that unloading magnet 24 or any other appended appliance may be positioned across the entire length of car 17 through the selected extraction and retraction of the pistons and cylinders and pivoting of the boom members 11, 12 and 13.Type: GrantFiled: December 20, 1990Date of Patent: March 31, 1992Assignee: Eastern Railway Supplies, Inc.Inventor: James Westlake

Patent number: 4684031Abstract: A material hoisting gin has a support beam which pivots atop a mounting bracket which may be releasably attached to an upright pole. A bar for supportably engaging a load is suspended from the beam in a manner which enables the bar to be raised so that it is closely proximate to the base of the beam. This arrangement enables the gin to be mounted with the beam very close to the top of the load (which is to be raised or lowered with respect to the pole). The gin can thus be used in situations where there is minimal operating clearance above the load. In particular, the gin can frequently be used to raise or lower distribution transformers on utility poles without encroaching upon the limits of approach to the overhead power lines.Type: GrantFiled: July 15, 1985Date of Patent: August 4, 1987Assignee: Frederick Sigurdur BergmanInventors: Frederick S. Bergman, Reginald P. Radelet

Patent number: 4659276Abstract: A load handling apparatus for a vehicle has a mounting frame with a mast movable between a lowered travelling position and a raised working position. A boom carrier on the mast pivotally supports an articulated boom, which has a winch at its distal end. The winch cable is attached to a load carrying cradle which has handle bars to be gripped by the operator and the switch controls for the winch. The mast is counter-balanced by a spring and turnbuckles connect the boom carrier to the mounting frame and the mast to tilt the boom carrier in two directions if the vehicle is on uneven ground.Type: GrantFiled: September 12, 1985Date of Patent: April 21, 1987Inventor: Trevor G.

Patent number: 4505397Abstract: An apparatus for hoisting materials and placing concrete, having a non-rotating mast and a boom which is swingable horizontally and vertically, and consists of boom segments pin-jointed together in line so as to be foldable only downwardly. A line of concrete transport piping extends from the base end of the boom to the free end thereof, and a line of hoisting sling extends from the base end of the boom to the free end, hangs down to hold a load handling block, rises up and extends back to the base end, each such line being supported alongside of the boom. In service for hoisting materials, the boom is stretched and fixed at each pin-jointed connection for reinforcement by releasable pin-fastening members, whereas in service for concrete placing, the hoisting sling is raised up and seized in place to avoid interference. The apparatus is remotely controllable.Type: GrantFiled: March 30, 1983Date of Patent: March 19, 1985Assignee: Takenaka Komuten Co., Ltd.Inventors: Sakichi Isogai, Teruo Mizuhata, Masaaki Takahashi, Takayoshi Imai, Kazuyoshi Nakanishi, Takefumi Ito, Atsuo Koshihara

Patent number: 4418791Abstract: The free end portion of the boom of a crane carries a separable pivot bearing defining a horizontal pivot axis for a second bearing which reciprocably guides an upright column for one or more galleries. When the cable which is used to lift or hold the column breaks and the column begins to rapidly descend, such movement of the column activates a composite brake mounted on a frame surrounding the column at a level above the second bearing. The brake holds the column against downward movement with reference to the frame whereby the frame tends to descend toward the second bearing against the opposition of several shock absorbers which reduce the likelihood of damage to and/or excessive swaying of the boom and/or injury to the occupant or occupants of the gallery. The speed of downward movement of the column is monitored by a detector which activates the brake as soon as the speed exceeds a preselected value.Type: GrantFiled: March 26, 1981Date of Patent: December 6, 1983Inventor: Paul Frey-Wigger

Patent number: 4232792Abstract: A remotely controlled rotatable crane for loading logs on a live deck. The crane includes a carriage having a horizontal bed rotatable on a circular track about a verticle axis, the bed carrying a truss assembly extending upwardly and radially outwardly from the bed. The distal end of the truss assembly carries a vertically movable and rotatable grapple. A winch and cable raises and lowers the grapple. A counterweight is disposed on the carriage to counter balance the truss assembly. Electrohydraulic controls operate the winch for raising and lowering the grapple, controls the rotation of the grapple about a vertical axis and its opening and closing and controls the movement of the carriage about its vertical axis. Hydraulic motors also drive wheels on the track for rotating the carriage about a vertical axis.Type: GrantFiled: February 21, 1978Date of Patent: November 11, 1980Assignee: Kockums Industries, Inc.Inventor: Dean W.
