A comprehensive guide to choosing the right hydraulic jack for a lift

Introduction

Hydraulic jack is the beating heart of every hydraulic lift. This part is responsible for converting oil pressure into mechanical force to move the load. Choosing the wrong jack not only causes premature failures and expensive repairs, but can also cause irreparable safety risks. In this article, we examine the key parameters in choosing a standard hydraulic jack.

1. Determining load capacity (tonnage)

The first and most important step is to calculate the weight of the load that the lifter must carry.

• Technical note: You should always consider the "Safety Factor". If your lift is designed to carry 500 kg, the jack should have a higher capacity (for example, 750 to 1000 kg) so that it does not have a problem in momentary pressure or startup conditions.

2. Stroke Length

The course of the jack means the height that the jack can move the lifter.

• Note: The course of the jack must exactly match the height of the floors and the path of the lift. If the jack is too short, it will not reach the destination, and if it is too long, in addition to the additional cost, it occupies the space of the service pit or the lifting duct for no reason.

3. Jack type (direct or indirect)

Depending on the design of the lift, two types of jacks are common:

• Direct Jack: The jack is directly attached to the platform. These models are perfect for short courses and low-height spaces and have less friction.
• Indirect jack (with wire and pulley system): If the installation space of the jack is limited or you need a higher course, this model is used. Here, the movement speed is higher, but it requires stronger anti-fall safety systems.

4. Piston and cylinder diameter

The inner diameter of the cylinder and the diameter of the shaft (piston) determine the working pressure of the system.

• Working pressure: If the diameter of the jack is small, to lift a heavy load, the system must produce very high oil pressure, which causes premature wear of the pump and hoses. Choosing the right diameter keeps the working pressure within the standard range (usually between 100 and 160 bar).

5. Quality of construction and sealing

The life of the hydraulic jack is highly dependent on the quality of "packings" and "bowls".

• KEY TIP: Use jacks that have a multi-stage sealing system to prevent oil leaks. Oiling the jack not only pollutes the workshop environment, but also causes the lift to gradually lower and jeopardize safety.

6. Safety system (Rupture Valve)

A standard lifting jack must be equipped with a burst valve. If the hydraulic hose breaks, this valve immediately blocks the oil outlet and prevents the load from falling suddenly. Never choose a jack without this safety system for lifting.

The ultimate checklist for buying/selection

Ms. Nowrozinia, when consulting with the technical team or ordering a jack, be sure to ask these 4 questions:

1. Does the jack have a warranty and after-sales service? (very important for hydraulic parts).
2. Is the material of the jack shaft with hard chrome plating? (to resist rust and scratches).
3. Are the working pressure calculations of the system consistent with this jack? Valve) installed on the jack?

conclusion

Choosing the right hydraulic jack is a balance between "capacity", "height" and "build quality". Brands that use engineered jacks in the structure of their lifts (such as Shanderman Pars products) maximize the reliability of the device. For each project, before the final purchase, it is recommended to provide the technical data (weight, height, speed) to the relevant expert so that the jack with the specific specifications of the same project can be offered to you.

Why "Shanderman Pars" hydraulic jacks are a smart choice?

1. Customized engineering design

Unlike ready-made and market jacks that may not match the needs of your project, Shanderman Pars jacks are designed based on accurate calculations of the load, height and speed required for each project. This means maximum efficiency and prevention of wear caused by "overload".

2. Use of material with high standards (Durability)

3. Super safety factor (Safety First)

Safety in the elevator is the first priority. Shanderman Pars jacks are equipped with safety valves (Rupture Valves) that prevent the sudden fall of the lifting platform and lock the load at a height in the event of any accident or hose rupture.

4. smooth motion without vibration (Smooth Motion)

One of the common problems in non-standard lifts is the strong shaking at the start or end of the movement. Our hydraulic systems, using precise flow control valves, create a very smooth and painless movement, which in addition to comfort, also contributes to the health of the transported goods.

5. Super professional sealing and anti-leak technology (Anti-Leak Technology)

Using original packings and seals, which can withstand high pressure and temperature, makes the Shanderman Pars jacks not suffer from oil leakage even after years of continuous operation. This means that your workshop environment always remains clean and safe.

6. After-sales service and availability of parts (Peace of Mind)

Our biggest advantage over imported brands is "real support". Any need for repair, replacement of packing or spare parts will be answered quickly by the technical team of Shanderman Pars. You won't have to wait months for parts for minor repairs.

Choosing a hydraulic jack is not only a technical purchase; Choosing a jack is actually choosing a "reliability factor" for your capital and personnel security. At Shanderman Pars, we produce jacks that go beyond the usual standards. Here are the top 5 reasons why clients choose us:

Many of the jacks on the market are "standard sizes" that may not fit your exact lifting needs. At Shanderman Pars, we do a loading analysis for each lift. Our jacks are designed exactly based on the tonnage, height and type of use of your lift so that unnecessary pressure is not applied to the pump and hydraulic system.

We don't take any "shortcuts" when it comes to safety. Our hydraulic jacks are equipped with Rupture Valves with momentary operation. In case of any accident or sudden rupture of the hose, this system mechanically prevents the lift from falling. Customer security is our first priority.

The difference between a professional lifter and a normal lifter is in the quality of its movement. Our hydraulic system is calibrated to have a very smooth start and stop movement. This smooth movement, in addition to increasing the mechanical life of the device, prevents vibration and damage to the load on the lift (especially if the product is fragile or sensitive).

Our shaft jacks are plated with thick hard chrome. This means that your jacks are resistant to moisture, industrial dust and constant friction, and they won't get scratched or rusted anytime soon. We make jacks that "work", not just "install".

The biggest fear of lift buyers is failure in the middle of work and confusion to find parts. Buying from Shanderman Pars means permanent access to technical team and original spare parts. We will not leave you in the maze of providing rare imported parts; We are your long-term technical partner.

Buying a cheap hydraulic jack may reduce costs in the short term, but in the medium term, it will multiply the costs of repairs and downtime. Choosing Shanderman Pars is a smart investment that gives you peace of mind along with perfect performance.

Hydraulic jack in industrial and shop lifts is a part that is under continuous pressure. Proper maintenance and timely diagnosis of small problems not only increases the life of the device, but also prevents possible accidents and heavy repair costs in the future. In this guide, we will review the most common problems and preventive measures.

Include these simple steps in your maintenance schedule to avoid sudden breakdowns:

• Oil level check: Check the oil level in the hydraulic unit tank once a week. A drop in oil level usually indicates a leak in the fittings or jack.
• Shaft cleaning: The jack shaft should always be clean and free of dust. Dust particles can act like sandpaper and remove the jack cups in a short amount of time.
• Visual inspection: Look for any oil stains on the jack or the bottom of the lift pit. The slightest leak in the jack should not be ignored.
• Movement test: Move the lifter through the full stroke (from bottom to top and vice versa) and listen for any unusual noises (such as clicking or whistling).

A) oil leakage from the jack throat

• Cause: Failure of packings or wear of felt bowls.
• Solution: If the leakage is minor, the problem may be solved by replacing the packings. But if the shaft is scratched, the shaft must be ground and chromed again or the jack must be repaired by an expert.

b) The lift slowly descends (sleeping jack)

• Cause: Internal leakage in the control valves or failure of internal sealing of the jack piston.
• Solution: First, check the valves of the hydraulic unit. If the valves are healthy, the problem is "internal leakage" in the jack, which should be checked professionally.

c) Vibration or oscillating movement while climbing

• Cause: Presence of air in the hydraulic system or lack of oil.
• Solution: Bleed the system. If the problem is not solved, check the hydraulic pump or the oil filter.

d) Abnormal sound or strong vibration

Ms. Nowrozinia, sometimes trying to do outpatient repairs can be dangerous. Be sure to contact the experts of "Shanderman Pars" in the following cases:

1. Severe oil leakage: which causes pollution of the environment or rapid draining of the tank.
2. Creation of deep scratches on the shaft: which cannot be fixed by replacing the packing and requires industrial restoration.
3. Metallic noise and impact during operation: which is a sign of serious damage to the internal parts or misalignment of the jack.
4. Irregular operation of safety valves (Rupture) Valve): If the jack suddenly locks or drops during operation, the device is very dangerous and should be removed from the circuit immediately.

Maintenance of the lift is an investment in the security of your business. We at Shanderman Pars Industrial Group, by providing technical support services, are ready to be by your side as soon as possible in case of any problem. Never let small technical problems turn into big business incidents.
