绞车提升和牵引设备发现我n industrial sectors such as metalworking and construction for lifting and moving heavy loads, in the maritime industry for lifting boats, in the automotive sector for towing vehicles on trailers, etc.
There are four main ways of powering a winch: electric motors, combustion engines, hydraulic drive and manual drive.电动绞车可分为两类：连接电机和电池供电的电机，例如连接到汽车或卡车。电动绞车适用于间歇性使用，因为它们变得非常热。我们建议您使用配备热熔丝的绞盘，以避免如果负载太重或者如果过于密集使用，则避免损坏它。此外，选择具有比需要更高的绞车，避免过热。
If you choose a winch that runs on battery power, make sure that the battery you use is sufficient to power it. With a 12-volt power supply, a winch can have a peak consumption of more than 400 amps.
由燃烧发动机提供动力的绞车are heavier and more expensive than electric winches. They generally have a duty ratio of 100% however, so they can be used continuously.
Hydraulic winchesare connected to a hydraulic circuit that drives the drum. Their duty ratio is also 100% and they generally have very high load capacities. The hydraulic system must be well adapted to this use however: a hydraulic winch can require a pressure of up to 160 bar and a flow rate of up to 60 liters per minute (l/min). These winches are used on ships or offshore platforms, for example.
手动绞车必须根据所需的牵引速度由一个或多个人操作。手动绞车可以有一个crank(to operate it, a continuous rotational movement is required) or alever（在这种情况下，您必须抽出它）。这些绞车通常设计用于通过缠绕牵引或提升装置手动操作。它们配备了脱离系统，使得牵引装置在负载的重量下展开。它们主要用于提升中等负荷。
Generally manual winches have a lifting capacitylimited to 2 tonnesfor the largest ones.
Selection criteria for choosing a manual winch

为了计算你的绞车的尺寸，你必须知道the loador maximum capacity it can pull, this load must be higher than the maximum weight you will need to lift or tow, in order to avoid any accidents. In general, it is necessary to provide a traction capacitytwice as much as the load to be towed。你至少必须考虑到一个safety margin50％。绞车容量通常以磅（LBS）或千克（KG）表示。您可以快速转换最大负载：一磅等于0.45千克。
