Mechanical car jack

Types of mechanical car jacks

A mechanical car jack, also known as a hand jack, is a jacking device operated by mechanical means, such as a crank, lever, or ratchet. It is used to lift loads vertically. There are various types of mechanical car jacks:

• Scissor jack

  Scissor jacks, also known as X-frame jacks, are among the most commonly used car jacks. They are compact and lightweight, making them easy to carry in vehicles. A scissor jack uses a screw mechanism to lift the vehicle. The screw is turned with a lever, which causes the two arms of the jack to move apart, raising the lift platform. The scissor jack's simple design and affordable price make it a popular choice for emergency tire changes.

• Floor jack

  Another type of mechanical car jack is the floor jack, also referred to as a trolley jack. A floor jack is commonly used in garages and workshops. It has a hydraulic mechanism that provides a higher lifting capacity with less effort. A floor jack has a large lifting range, allowing it to lift vehicles with low clearance. The design of the floor jack, which includes wheels, enables easy maneuverability under the vehicle.

• Hi-lift jack

  The high-lift jack, also known as the farm jack, is primarily used for off-road and farm vehicles. It is a mechanical jack with a vertical lifting mechanism that can lift vehicles to great heights. The high-lift jack can be used for a variety of applications, such as pulling, clamping, and lifting. Because of its multipurpose capabilities, the high-lift jack is commonly used in rural areas where the roads are unpaved.

• Bottle jack

  A bottle jack, also known as a cap jack, is a compact jack with a cylindrical body that resembles a bottle. This mechanical car jack uses a hydraulic system to lift vehicles. Bottle jacks are capable of lifting heavy loads to great heights. The lifting height of a bottle jack is higher than that of a scissor jack. On the downside, a bottle jack is heavier and more difficult to slide under a vehicle, especially one that is low to the ground.

Specifications and maintenance of mechanical car jack

These are some standard specifications to look for when buying a mechanical car jack:

• Weight capacity

  Weight capacity is the maximum weight the jack can lift. For a car jack, the weight is usually given in tons (e.g., 2-ton or 3-ton jacks). A 2-ton jack can lift vehicles weighing up to 2000 kg, while a 3-ton jack can lift vehicles weighing up to 3000 kg. People should always use a jack with a weight capacity greater than their vehicle's weight. Using a jack with lower capacity could cause the jack to fail.

• Lift height

  Lift height is the distance the jack can raise a vehicle. For a car jack, lift height is usually given in centimeters (e.g., 20 cm or 30 cm). A jack with a lift height of 20 cm can raise a vehicle 20 cm off the ground, while a jack with a lift height of 30 cm can raise a vehicle 30 cm off the ground. The required lift height depends on the type of repair being done. For example, tire changes require a higher lift height than oil changes.

• Jacking points

  Jacking points are specific locations on a vehicle where a jack should be placed to lift the vehicle safely. Each vehicle has designated jacking points, usually shown in the owner's manual. Using incorrect jacking points could damage the vehicle or cause the jack to be unstable.

• Safety features

  Mechanical car jacks include safety features to prevent accidents. These features include overload protection (to stop the jack if the weight exceeds its capacity), stability features (to keep the jack stable while lifting), and a locking mechanism (to keep the vehicle in the lifted position).

Here are some tips for taking care of mechanical car jacks:

• Follow the manufacturer's instructions

  Always use the mechanical car jack according to the manufacturer's instructions. Read the user manual to understand how to use the jack safely and correctly.

• Regular inspection

  The mechanical car jack should be inspected regularly for wear and damage. Check the jack for cracks, rust, or other damage before each use. If any damage is found, do not use the jack and repair or replace it.

• Keep clean

  Keep the mechanical car jack clean and free of dirt and debris. Dirt and debris can affect the jack's performance and cause wear or damage over time. Wipe the jack with a damp cloth and remove any dirt or debris.

• Lubrication

  The mechanical car jack should be lubricated regularly to keep it working smoothly. Use the lubricant recommended by the manufacturer and apply it to all moving parts of the jack.

• Correct storage

  The mechanical car jack should be stored in a dry place away from direct sunlight and heat sources. Do not store heavy objects on top of the jack, as this could cause damage.

• Training

  Only trained people should use the mechanical car jack. Ensure everyone using the jack has received training in its safe and correct use. Provide training on inspecting, maintaining, and using the jack safely.

How to Choose Mechanical Car Jack

Before sourcing an ideal mechanical car jack for sale, here are some important factors to consider:

• Weight Capacity

  When selecting a mechanical jack, always consider its weight capacity. It should surpass the vehicle's weight. Typically, the vehicle's weight is found in the owner's manual. For safety reasons, the jack should handle at least 1,500 pounds more than the vehicle's weight.

• Vehicle Compatibility

  Buyers should ensure the jack is compatible with their vehicles. This includes considering the jack's size and design. For instance, some vehicles with low clearance require a low-profile jack.

• Portability and Storage

  Business buyers should consider where the jack will be stored and if it will be transported. A smaller and lightweight jack is more convenient. Mechanical jacks like bottle jacks are more portable than scissor jacks.

• Stability and Safety

  To enhance stability, buyers should select jacks with a wide base. They should also consider safety features like overload valves that prevent the jack from lifting beyond its capacity.

• Ease of Use

  The mechanical car jack should be simple to operate. Jacks with handles that require minimal effort to lift the vehicle are ideal. Additionally, buyers should consider jacks with wheels that enable repositioning when lifting the vehicle.

• Construction Material

  Steel and aluminum are common materials used to construct mechanical car jacks. Steel jacks are durable, while aluminum jacks are lightweight. Buyers should consider the material based on their needs.

• Price

  Business buyers should have a budget when purchasing a mechanical car jack. However, they should avoid cheap jacks since they are of low quality. A good mechanical car jack has a reasonable price, depending on the type and features.

• Warranty

  Buyers should purchase mechanical car jacks that offer a good warranty period. The warranty shows the manufacturer's confidence in the product. Additionally, they should read the warranty terms to know what is covered.
