    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. 
    Above is a comprehensive introduction to the trolley jack. If you are searching for a good quality trolley jack at competitive prices, Omega Machinery can provide you with the best products to meet your needs.

What are the features or advantages of Trolley Jack?

Now, let's discuss various features and advantages that make trolley jacks so popular among car lovers and mechanics.

  1. Low-profile design

The trolley jack has a compact body accompanied by an ergonomic handle that contributes to its easy operability. It can smoothly slide beneath the car with low ground clearance effortlessly. Thus, it can lift lowered vehicles, sports cars, and other automobiles within tight spaces below the chassis.

  1. Hydraulic system

The hydraulic system helps in the easy operability of the trolley jack. This system helps to lift vehicles of different weights at the desired height with minimal effort. When the ergonomic-shaped handle of the jack is pumped, the hydraulic fluid gets compressed, thereby transferring the pressure to the lifting arm. This, in turn, helps the users to lift the cars with ease.

  1. High lifting capacity

Despite its compact frame, this trolley jack has impressive lifting capacity. Its saddle height can be adjusted to lift cars of different models with various sizes and weights. It can even lift heavy loads of up to 5 tonnes. Thus, it is an essential tool in almost all workshops and garages.

  1. Safety

With a sturdy construction, the trolley jack offers stability and minimizes risks of spillage or accidents during use. It is equipped with overload valves to prevent overextension, ensuring safe operation. Further, it has advanced safety features such as quick foot-pump lifting and quick-release handles that provide controlled accuracy while lifting the cars.

  1. Portability

The sturdy wheels, along with integrated handles, make the trolley jacks a portable device. Due to its lightweight, these jacks can efficiently be transported from one place to another across the remote worksite.

  1. Durability

Made of high-quality materials like steel or aluminium, trolley jacks are designed to endure the consequences of frequent use in different environments. Its compact yet strong frame ensures durability, provided its regular maintenance is taken care of.

How does a Trolley Jack work?

  Since a trolley jack helps to lift different vehicles easily, it becomes necessary to understand its functioning to operate it efficiently to avoid any accident. Here, the first step is to opt for an appropriate trolley jack, keeping in mind the weight of the vehicle. When the vehicle is parked, identify the jack points under the vehicle' s machinery. Finally, place the jack on ground level at the closest lifting point.
  The governing principle of working of a trolley jack is the hydraulic system. This system is surrounded by a sturdy steel frame, comprising various components which include a hydraulic pump, ergonomic handle, saddle, and lifting arm. When the mechanical force is put on the handle, the attached hydraulic pump transfers the force received on the stored fluid in the reservoir. As the intensity of the force rises, this fluid, usually known as hydraulic fluid, moves through a mesh of interconnected valves inside the chambers of the system. This transmitted power helps to lift the vehicles easily. Further, this hydraulic fluid moves throughout the system to reach the piston. The piston is present in the main cylinder of the system and is connected to the lifting arm. It helps to extend the jack vertically below the vehicle. The piston starts moving vertically within the cylinder when it receives the force from the fluid. As the piston rises, the lifting arm is elevated, further lifting the connected saddle. The saddle offers stability to the jack for lifting the vehicles as it establishes direct contact with the base of the vehicle. 
   Through this process, the vehicle is lifted and then maintenance or repair services can be performed. After the task is completed, the jack stand is carefully removed by moving the release valve slowly on the handle of the trolley jack.
