The first of these systems used mechanical clutches between luffing and hoist drums, giving simplicity and a "near level" result. [ 5 ] Later systems have used modern electronic controls and quickly reversible motors with good slow-speed control to the hoist winch motors, so as to give a positioning accuracy of inches.
[4] [5] Hydraulic "active boost" winches control the oil flow from the pump(s) to the winch so that the target position is reached. Hydraulic winch systems can use accumulators and passive heave compensation to form a semi-active system with both an active and a passive component. In such systems the active part will take over when the passive ...
Network 1: A wireless base station acting as a simple (non-WDS) wireless router. The packet leaves the game console, goes over-the-air to the router, which then transmits it across the WAN. One packet comes back, through the router, which transmits it wirelessly to the game console. Total packets sent over-the-air: 2.
Breeze-Eastern is the world's only dedicated helicopter hoist and winch provider and the world's second-largest cargo hook systems manufacturer. The company focuses on engineered equipment for specialty aerospace/defense applications. It also manufactures weapons handling systems and tie-down equipment for military and civilian agencies. [2]
The winch is either controlled with a detachable cable, a button inside the car or wireless remote. Older vehicles may have a PTO winch, controlled via the car's transmission, a secondary clutch maybe used so the vehicle does not need to be moving while winching. Some winches are powered by the pressure generated in the hydraulic steering system.
A drum hoist (steel wire rope visible) and motor. In underground mining a hoist or winder [1] is used to raise and lower conveyances within the mine shaft.Modern hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solid-state converters (), although modern large hoists use alternating current drives that ...
Constant tension is intentionally maintained on the cable via an automatically-adjusting hydraulic system connected with multiple high-sensitivity tension sensors, and a shock absorption system. [1] Fail-safes are incorporated into the device as well. When the LSO determines that a relatively quiet moment is approaching, they instruct the pilot ...
Other examples are fly-by-wire systems in aircraft which use servos to actuate the aircraft's control surfaces, and radio-controlled models which use RC servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the lens. A hard disk drive has a magnetic servo system with sub-micrometer positioning accuracy ...
