All About Ombra Jacks

In the hand tool market Ombra brand has established itself as a reliable, high-quality and high-tech manufacturer. All lines of tools are made in compliance with international standards, they fully comply with Russian requirements for this type of product. Today we will take a closer look at the jacks of the Taiwanese company Ombra.

The tools of this brand have many advantages and stand out from all brands of the middle price category.

The main feature of all equipment - the use of high-alloy chromium-vanadium steel with a special coating, which allows to increase the service life. Thanks to unique style of performance Ombra jacks much more ergonomic and more practical similar devices from other manufacturers.

Devices are classified by type of work. Let's list the main ones.

1. Mechanical... In principle of action - the applied physical force moving the screw.
2. Hydraulic... The basis of work is the pumping of a chemical fluid (mainly hydraulic oil, but some models use brake fluid) into the cavity. There are one-valve and two-valve models.
3. Pneumatic... The main action is to pump air into the working cavity of the lifting mechanism. A compressor is often needed additionally.
4. Electrohydraulic... It works on the principle of hydraulic equipment, but the force is not carried out mechanically, but with the help of an electric current.
5. Pneumohydraulic... Hydraulics, which is influenced by air from compressor equipment.

Structurally, jacks are divided into the following types.

• Rhombic... Otherwise, such a device is called a trapezoid or trapezoidal jack. It has a diamond shape, any sidewall of the structure is movably connected to each other. When the lever is rotated, the lateral corners converge, and the upper and lower, on the contrary, diverge.
• Pills... They look like small cylinders, which is why they were given such a name. Refers to hydraulic devices.
• Rack... The principle of operation - the lift moves along a toothed rack.
• Wedge... These jacks are triangular in shape and are driven mechanically or hydraulically.
• Bottle (or telescopic). Basically, the hydraulic drive raises the slave cylinder. They are divided into single-plunger and double-plunger lifts, but there are also three-plunger lifts.
• Lever... The design is presented in the form of a rack, the movement of which occurs due to the swinging drive of the lever.
• Screw... The lifting device moves due to the helical rotation of the lift mechanism.
• Trolley (otherwise they are called frogs or scissors). In the traditional version, this type of jack is a lifting arm, fixed on a base with a thrust heel. Powered primarily by hydraulics. By the length of the base, they are distinguished into short-wheelbase, medium-wheelbase and long-wheelbase versions.
• Selson's jack... Looks like a pillow in a reinforced rubber shell, which rises when air is supplied.

The company's economic policy is based on the principle - always take into account the wishes of their customers and improve equipment with their help. Several models of Ombra jacks are especially noted by Russian users.

• OHT202C. Excellent sliding hydraulic jack with a lifting capacity of 2 tons.The set includes a case for the tool. All users note reliability, simplicity and ease of use, reasonable cost. The disadvantages were attributed to the inadequate lifting height for some cars.

• OHT203... A rolling jack with a lifting capacity of 3 tons. Advantages: high quality construction, good lifting height, excellent price, ease of use. Of the shortcomings, some users noted a significant weight - 19 kg, as well as the lack of a rubber support in the kit.

• OHT225C in the case. Carrying capacity - 2.5 tons. Among the advantages are the quality of workmanship, the presence of a semi-automatic safety stop and the reliability of the structure as a whole. Of the shortcomings, a removable handle is noted.

• OHT225... Carrying capacity - 2.5 tons. All users note the build quality, simplicity and reliability in operation, the optimal price. Of the minuses - the severity of the structure.

Choosing a jack for equipment - the question is very important and you need to approach it responsibly. The main selection criteria are the following parameters.

1. Carrying capacity... When choosing, you need to be guided by the actual weight of the vehicle and the lifting weight of the jack. The carrying capacity of the latter must exceed the passport data on the mass of the vehicle. Many people mistakenly take the weight of the equipped car, not taking into account, for example, the fullness of the luggage compartment, but the situations are different, so it is better to take into account other possible factors.
2. Lifting height... A standard 30-50 cm is enough for repairing the brake system, changing wheels or servicing the car.
3. Pickup height. The vehicle's ground clearance determines the choice of jack, but you should not consider devices with minimum pickup values ​​at a sufficiently high ground clearance.
4. Drive option. The most reliable is mechanical, but it requires significant physical effort. If financial possibilities permit, then it is better to take an electro-hydraulic jack.
5. Manufacturer... The jack is not a device on which you need to save, but it is not worth buying a very expensive one either. Consider when buying such factors as the material from which the equipment is made, the compliance of the declared characteristics with the test parameters.
