A car enthusiast or mechanic may be aware of various tools used in garages and workshops. Among these essential tools is a trolley jack, a piece of equipment that can easily lift different-sized vehicles. In the following article, we bring to you the basics of a trolley jack, its features, and advantages, followed by its operating mechanism. 
    In garages, repair shops, or even manufacturing setups, it is necessary to lift vehicles for repairs, tire replacements, or regular maintenance. In this situation, a trolley jack comes into play. It is a hydraulic device that is used for lifting heavy vehicles with minimal effort, irrespective of their size and weight, to a desired height.  Owing to the four wheels attached to its durable and compact metal frame, the trolley jack allows easy movement within a garage or flat-surface shops. It is important to opt for a jack of the appropriate capacity to lift the vehicle of different weights. The jack has lifting capacities ranging between 2 to 5 tonnes.
   While lifting vehicles of different weights, the trolley jacks should be operated effectively to ensure vehicle safety and avoid any accidents. Trolley jacks have a lower center of gravity and wider base which ensures stability, specifically while lifting heavy vehicles. Most trolley jacks have different locking mechanisms and safety valves to secure the jack at the desired height, usually between 100mm to 500mm, or even higher level. They have swivel casters that help accurate positioning below the lifting jack points while some include foot pedals or double-piston pump that help to easily operate the jacks effortlessly. Further, to prevent overextension or overloading, modern trolley jacks are equipped with built-in features like overload protection.  Despite being highly durable and accompanied by advanced features, these trolley jacks may have wear and tear with constant use. This can be avoided by regular maintenance of these jacks. Thus, the level of hydraulic fluid inside the jack should be maintained while lubricating its moving parts at a regular time interval.
   Trolley jacks are very reliable when it comes to lifting mechanism, provided the jack being used is of the right size, shape, and weight. They help in performing various tasks such as changing tires, regular service, or working on brake assemblies. At the same time, its regular maintenance and servicing are important to keep it functioning smoothly.
