A removably attachable rear loader attachment mechanism for attaching to a standard stock rear end refuse collection vehicle body, the removably attachable rear loader attachment including a pair of latch assemblies removably attachable to flanges associated with the rear end portion of the vehicle body, a hopper extension member removably attachable to the rear end portion of the vehicle body, a roller bar assembly having a pair of roller bar frame members each removably attachable to the respective removably attachable latch assemblies, and a hydraulic source attachable to the latch assemblies and to the roller bar assembly for moving such members for capturing and dumping a commercial container into the storage compartment of the refuse collection vehicle. A removably attachable winch mechanism is also removably attachable to the top portion of a standard stock rear end refuse collection vehicle body for aiding in the dumping of a commercial container.

A system for controlling operation of a winch assembly having an electric motor, a drum, and a cable. A controller is configured to access a winch load threshold, with the winch load threshold defining a hold zone and a reel zone, and one of the hold zone and the reel zone including loads greater than the winch load threshold and another of the hold zone and the reel zone including loads less than the winch load threshold. The controller is further configured to determine whether the drum is rotating, determine whether the winch assembly is operating within the hold zone or the reel zone, generate a hold current while the winch assembly is operating within the hold zone preventing rotation of the electric motor, and generate a reel current while the drum is operating within the reel zone permitting rotation of the electric motor.

Described herein are methods and systems for detecting and correcting errors when picking up and lowering a payload coupled to a tether of a winch system arranged on an unmanned aerial vehicle (UAV). For example, the winch system may include a motor for winding and unwinding the tether from a spool, and the UAV's control system may control the motor to lower the tether and monitor an electric current supplied to the motor to determine whether a payload has detached from the tether. This process of lowering the tether and monitoring the motor current may be repeated up to a predetermined number of times, at which point the control system may operate the motor to detach the tether from the spool, leaving both the tether and the payload behind.

Methods and systems are provided for a winch including a motor and a contactor assembly positioned within a same housing. In one example, the contactor assembly is coupled to the motor and includes two or more coils spaced apart from one another within a contactor housing of the contactor assembly and a brush assembly including a plurality of brushes surrounding a rotational axis of the motor and arranged axially to the motor armature.

The present disclosure discloses a winch for a vehicle including a base, a winding drum fixed on the base for winding a traction rope, a support fixed on the base, a transmission component, and a reciprocating component for driving the traction rope to reciprocate along an axial direction of the winding drum when the traction rope is wound onto or released from the winding drum. The disclosed winch enables an orderly arrangement of the traction rope when the traction rope is wound on or released from the winding drum.

A winch assembly including a winch housing body, an attachment structure, and one or more releasable clamps. The winch housing body may comprise a front wall, a rear wall, and at least one connecting wall that extends between the front wall and the rear wall. The front wall, rear wall, and connecting wall define a winch-receiving volume sized to house a winch device therein. The winch device may include a motor, a drum that is operatively connected to the motor, and a cable that is operatively connected to the drum. The attachment structure may be attached to the distal end of the cable. The one or more releasable clamps may be mounted to the rear wall. The one or more releasable clamps may be configured to clamp onto support rails of differing widths.

A method for operating a towing winch and an electric drive for a towing winch, the towing winch including a rotatable winch drum for spooling a spoolable medium, and an electric motor operably coupled to the winch drum to rotate the winch drum, wherein the electric drive is configured to be operably coupled to the electric motor, and configured to control, during a towing of at least one object connected to the spoolable medium, a tension of the spoolable medium between the winch drum and the at least one object to be towed to be equal to or lower than a tension limit value; and monitor, during the towing, a roll angle of the tug, and in response to the monitored roll angle of the tug being outside of a predetermined range, lower the tension limit value providing roll compensation.

A method for operating a winch and a winch comprising a winch drum for spooling a spoolable medium for mooring a vessel, and a winch drive configured to drive the winch drum, wherein, during the driving of the winch drum, at least when a monitored tension of the spoolable medium is between a second upper tension threshold and a second lower tension threshold, an absolute value of the driving speed of the winch drum is configured to have a value that is proportional to an absolute value of a difference between the monitored tension of the spoolable medium and a predetermined tension set point.

The present invention provides an automated removable frame system for transporting vehicles in a container. The frame system is be assembled in the container, the vehicles are loaded on the frame system, the container is shipped to the location, the vehicles are unloaded from the frame system, and the frame system is disassembled and returned to the manufacture or stored for later use.

The present disclosure discloses a double-speed electric winch and an operating method of the winch. The winch comprises two groups of planetary gears with different transmission ratios in a gearbox. The two groups of planetary gears have corresponding outer ring gears. The gearbox has a rotatable handle which has a locking head inserted in the gearbox. As the handle rotates, the locking head engages with the outer ring gears in different manners to provide a first rotating speed mode, a second rotating speed mode, and a disengaged mode.
