  • Patent number: 11034562
    Abstract: A modular powered hoist design comprises: 1) a multifunctional baseplate, which forms a foundation of the powered hoist design and comprises part of a guide system for a lifting media, and 2) an integrated lift/guide assembly, securing a liftwheel therein, that is attachable to the baseplate through attachment features formed within the baseplate. Embodiments allow for different components of a powered hoist to be interchanged in the case of material incompatibility or to provide higher guide performance (such as accommodating different safety factors). Moreover, in manufacturing, embodiments allow for the use of overlapping product parts across different powered hoist product designs, thereby reducing overhead-related costs.

  • Patent number: 10765092
    Abstract: A rotary high lifter and controlled descender has a main housing enclosing a ratchet spool, controlled descender, and locking pawl. An adjustable crank turns the ratchet spool and takes up rope which raises an attached feeder, nestbox, etc. The locking pawl assures that as the rope is wound, the lifter/descender automatically locks in place so that an inadvertent crank release of the crank does not cause the feeder to fall. The rope exits the main housing via an inlet nipple which protects the housing from the elements, insects, etc. To lower the feeder, actuate a cam lock to release the locking pawl, and turn the crank in the opposite direction. Releasing the cam lock can actuate a controlled descender portion of the invention. These components apply a brake-pad-like action against the ratchet spool (can also use a tension knob) to control the speed of rotation and descent.

    Abstract: A cable drawworks for a drilling rig is provided having a three-phase AC electric motor controlled by a variable frequency drive control system. A primary drive transmission consisting of a chain and sprockets connects the motor to a drum shaft that passes through the hub of a cable drum such that the cable drum is rotatably mounted on the drum shaft. The drum shaft connects to a secondary drive transmission, attached to the frame via an oscillating plate assembly, that connects the drum shaft to the cable drum. Each end of the cable drum has a brake drum and a brake band wrapped around thereon. A brake actuating system is used to tighten the bands around each drum during braking conditions and includes an equalization linkage system between the brake bands resulting in equal braking forces being applied to each brake drum.

  • Publication number: 20110180770
    Abstract: A winch includes a rotatable drum. A cable is wound onto the drum in one rotative direction and off the drum in a second rotative direction. A sealed axial flux permanent magnet drive motor includes a drive shaft selectively rotated by the motor in either direction of rotation. A gear train interconnects the drive shaft and the drum for rotatably driving the drum at a reduced rotative speed relative to the motor shaft. The motor can apply regenerative braking. A spring-applied electric release brake is connected to the drive shaft to apply a braking force to prevent rotation of the drum. A connecting shaft connects the gear train to the rotatable drum. The connecting shaft includes axially spaced splines that reduce the disparity in the gear train and drum centerlines to thereby reduce gyration therebetween. The drum can be made partially from carbon fiber to reduce the weight thereof.

  • Patent number: 7984894
    Abstract: A clutch operable with equipment, including a winch of the type having a planetary gear reduction assembly for driving a cable drum. The planetary gear assembly includes a ring gear which, when allowed to rotate, effectively disconnects the drive motor from the cable drum. When the ring gear is fixed against rotation, the drive motor can drive the cable drum to wind or unwind the cable therefrom. A bistable solenoid is employed so that a plunger thereof is engageable with the ring gear to either allow rotation or prevent rotation, and thus engage or disengage the clutch. The bistable solenoid does not require electrical power when the plunger is in either stable position, thereby conserving electrical energy.

  • Patent number: 7891641
    Abstract: A clutch mechanism (75) for use with a machine to disengage the machine until normal operation thereof is commenced. The clutch mechanism (75) includes a clutch engaging member (130) movable into engagement with a notch (77) of the ring gear (76) of a planetary gear stage (70) to engage the clutch, and movable out of engagement with the ring gear (76) to disengage the clutch mechanism (75). The clutch engaging member (130) is spring biased to a position in which the clutch mechanism is engaged. A manually-operated handle (120) moves the clutch engaging member (130) via a link (128) and clutch actuator (122) from a clutch engaging position to a clutch disengaging position.

  • Patent number: 7823864
    Abstract: The present invention discloses a plane braking device for electric winches and electric winch which disposes a section of hollow gear shaft, a section of core shaft, a fixing ring, a wedge shape support, a stopping piece, a braking plate, an elastic element, a wedge shape piece B, a wedge shape piece A, a braking clutch base and so on in a gear box of an electric winch. When a motor works, the section of core shaft of the motor drives the braking clutch base and the wedge shape pieces A, B to rotate, until a gap is formed between the adjacent braking plate and stopping piece between the braking clutch base and the wedge shape piece B, so that the braking effect disappears. When the motor stops suddenly, a heavy load lifted by a tight wire drum provides a reverse pulling force so that the wedge shape piece B produces a reverse thrust force to push the friction planes of the braking plate and the stopping piece, so the plane braking effect is achieved quickly.

The planetary reduction gearbox of the winch assembly includes a primary sun gear, a first plurality of planet gears, a secondary sun gear, a second plurality of planet gears, and a ring gear. The primary sun gear is fitted with a drive head, which is configured for engagement by a handheld torquing device, such as an electric drill. The rotation of the primary sun gear results in the subsequent rotation of a cooperatively engaged gear-driven lifting assembly, to which a rope, cable, or strap may be attached for hoisting equipment. Optionally, a handle assembly may also be included, the handle being selectively disengageable from the lifting assembly, so that the handle may be remain stationary with respect to the rotation of the primary sun gear.
