A remote controller includes a shell having an upper shell and a lower shell, and further includes a light emitting module and a fixing plate for fixing the light emitting module. The fixing plate is fixedly connected to an inner side of the lower shell. The light emitting module is fixedly connected to one side, far away from the lower shell, of the fixing plate. The fixing plate is provided with a first light-transmitting hole for displaying the light emitting module; and the lower shell is provided with a second light-transmitting hole for displaying the fixing plate.

Methods and systems are provided for a winch including a motor and a contactor assembly coupled around the motor. In one example, the contactor assembly is coupled around and in face-sharing contact with a portion of an outer surface of the motor. Additionally, the contactor assembly may include two or more coils spaced apart from one another within the contactor assembly.

A damping mechanism may comprise a housing, a shaft, a spring arm assembly including a first spring arm, wherein the spring arm assembly is coupled to the shaft and configured to rotate in response to a rotation of the shaft, wherein the first spring arm extends relatively radially outward of the spring arm assembly toward the housing in response to the rotation of the shaft, and wherein the rotation of the shaft is damped in response to extending the first spring arm.

Methods include deploying a downhole tool into a wellbore with a conveyance apparatus by mounting a tool to a distal end of a spooled conveyance apparatus, routing the conveyance apparatus around a powered sheave assembly, which includes a plurality of grooves disposed on the outer surface of the sheave to accommodate the conveyance apparatus, and providing a power source for applying torque to the powered sheave. The powered sheave assembly then deploys the conveyance apparatus into the wellbore. In some cases a traction device may be disposed between the powered sheave and the wellbore to provide axial force in both directions. The conveyance apparatus is moved through a sealing apparatus, a blowout preventer, and a wellhead, with the powered sheave, after the routing the conveyance apparatus around a powered sheave.

A baler includes a body, and a wrap system that is attached to the body. The wrap system is operable to support a roll of wrap material in an installed position. A cover is attached to the body, and is moveable between an open position and a closed position. When in open position, the cover provides access to the wrap system from an exterior location. When in the closed position, the cover encloses the wrap system from the exterior location. The baler includes a lift system attached to one of the body and the cover. The lift system is concealed between the body and the cover when the cover is disposed in the closed position. The lift system is positioned below the cover when the cover is disposed in the open position. The lift system raises the roll of wrap material into the installed position.

An overload protection mechanism for a winch that includes an input transmission shaft, an output transmission shaft, and a clutch mechanism. The input transmission shaft has a first transmission end, the output transmission shaft has a second transmission end. The clutch mechanism has a first clutch member disposed on the first transmission end and a second clutch member disposed on the second transmission end such that the first and second clutch members are correspondingly rotatable with the input transmission shaft and the output transmission shaft. The first and second clutch members are detachably engageable with each other. When the output transmission shaft is overloaded, the first and second clutch members are disengaged for preventing the overloaded power transmission between input transmission shaft and output transmission shaft.

An adjustable length winch apparatus is disclosed. The adjustable length winch apparatus comprises a first motor, a first drum, a second drum, and a shaft. The first motor is configured to rotate the first drum and the shaft on an axis. The second drum is adapted to be rotated by the shaft on the axis. The shaft and the second drum are configured to adjust the distance between the first and second drum.
