Coil spring compressors, spring coil compressors or just spring compressors are tools that are used to install and remove vehicle coil springs.

Coil springs are part of the shock-absorbing system of a vehicle. They absorb road impact, support the weight of your car, keep the wheels on the road surface and keep the vehicle at the correct height.

Coil springs store energy

Coil springs store energy when they are compressed by the weight of a vehicle and its load. The energy is released once the weight is lifted and the spring expands to its original dimensions.

Because coil springs store energy, they are effective in carrying heavy loads and “smooth” the movement of a vehicle on bumpy roads.

Coil springs are made from carbon, silicon, manganese, and chromium, which makes them firm, flexible and “springy”.

Because they need to carry heavy loads on bumpy roads, spring coils are compressed to shorten the spring and store energy for release when required.

Coil spring compressors compress springs

Coil spring compressors should be distinguished from other workshop presses.

A coil spring compressor compresses an extended coil spring and stores the energy needed when a vehicle is loaded or travels over bumps.

Intense force is needed to compress the coil spring, which is what the spring coil compressor is used for.

All workshops that provide services related to car suspensions need a coil spring compressor in the workshop.

Coil springs need to be compressed to a force that human power cannot do, so a tool is needed for that.

The coil spring compressor does just that.

Trolley jacks

The purpose of trolley jacks, like all other auto workshop tools, is to make auto repair work more productive.

There are three main types of jacks namely
screw jacks,
trolley jacks, and
bottle jacks.

Risks for auto mechanics

Research shows that there are three main areas of risk for auto mechanics:

• overstraining of organs (muscles and ligaments),
• the impact from objects and moving items,
• being crushed by heavy objects.

Trolley jacks are usually used to lift a motor vehicle to access its interior component or extract certain parts such as gearboxes for repair and maintenance.

How trolley jacks work

Trolley jacks are hydraulically powered to create maximum output with minimum effort.

The operator needs to apply a small amount of force (energy) to get a large amount of power. The size of the piston and the strength of the wheels determine the power of the trolley jack and the load it can lift.

A quality trolley jack like the Snapon has a pump that allows the pivot arm to go from lowered position (100mm) to meet the load in the least number of pumps. The length of the handle contributes to the ease with which the trolley jack can be used.

Hydraulic jacks function on Pascal’s law, which states that the intensity of pressure at any point in a fluid at rest is same in all directions.

If two cylinders (a large and a small one) are connected and force is applied to one cylinder, equal pressure is generated in both cylinders. However, because one cylinder has a larger area, the force produced by the larger cylinder will be higher. The pressure in the two cylinders will remain the same.

Hydraulic jacks operate on this law. The two-cylinder hydraulic jack operates by applying force to the smaller cylinder which results in the same amount of pressure in the larger cylinder. Since the larger cylinder has more area, the resulting force will be greater, and that allows the operator to lift a car that would be impossible to lift manually.

Quality trolley jacks

Looking at the design of trolley jacks and the physics that it is based on, it is clear that inferior trolley jacks can be dangerous in an auto shop.

Hydraulic systems that are made from too weak or sub-standard materials can lead to serious accidents and loads of trouble for auto shop owners.

That is why GTS Equipment only stocks brand names that have proved themselves and have stood the test of time and intense use in workshops all over the world.

Price should be low on the list when buying trolley jacks for auto shop or home garage use.

GTS stocks trolley jacks that are much cheaper than a hospital account.

Anyone can start a tyre changing shop in their town or suburb.

What is a tyre shop?

Tyre changing services is one of the basic automotive services in the country with a broad scope because of the quality of our roads and the number of vehicles that travel each day.

Once you have premises and meet the legal and financial requirements, you can start sourcing the machinery needed for a successful tyre shop.

What services does a tyre changing shop offer?

A tyre shop usually offers a range of tyre services, such as puncture repairs, tyre damage inspections, new tyre sales, wheel balancing, wheel alignment and wheel rim services and sales. In short, any need there may be related to tyres can be a possible service or product opportunity for the enthusiastic entrepreneur.

Some tyre shops offer additional services such as windscreen repairs.

What do you need to start a tyre shop?

When you decide to start a tyre shop and you have done all the groundwork, it is time to equip your shop.

A tyre shop needs a range of equipment, but the good news is that you don’t have to buy it all at once.

You can start a shop with basic equipment and expand it as your business grows.

A tyre shop will have these tools and machines:

• Tyre-changing equipment for cars. If you are in a rural area you may benefit from a tractor tyre changing machine.
• An air compressor because most tyre shop tools work on air compression.
• A lift to lift the vehicle when changing tyres.
• Wheel alignment equipment.
• A wheel bay toolset.
• A well-supplied toolbox.
• A truck and car wheel balancer.
• A range of wheel balancing accessories.

It can have many additional tools and equipment, depending on the size of the business and how busy it is.

What else do I need to have a fully equipped tyre shop?

You could add these tyre tools and equipment:

• Workshop equipment
• Alignment lifts and racks
• Auto workshop lifts
• Battery Equipment
• Passenger wheel alignment equipment
• Passenger tyre changers
• Truck tyre changing equipment
• Tyre repair equipment
• Brake equipment
• Diagnostics equipment
• Passenger wheel balancers
• Truck alignment and balancing equipment
• Balancing accessories
• Workshop tool sets
• Alignment tools and accessories

Conclusion

If you are unsure whether there is space for a small independent tyre shop in your area, keep in mind that all major businesses started as small businesses.

It depends mostly on whether you stand out in a part of the business that is important to potential customers. It may be the speed with which you deliver your services or whether you do something better than the competition.

You may also decide to go the easier route of getting a franchise.

That makes it much easier to start your tyre shop and avoid much of the pain and potential errors of doing it on your own.
