Low Profile Hydraulic Cylinder: How It Works, Uses & Benefits
When it comes to handling heavy loads that need lifting but there’s no room for traditional hydraulic cylinders, you’re going to want one of our low-profile hydraulic cylinders on your side. Our hydraulics are designed for space constraints with their short stature but a substantial amount of lifting power.
This type of equipment goes by several names depending on the manufacturer – from low-height hydraulic cylinder to low-profile hydraulic ram. They’re widely used for operations requiring heavy lifting, such as positioning, aligning, or maintenance work. At BEMCO JACKS, we provide compact solutions designed to meet demands within even the most challenging settings found across industry sectors. We offer flat and ultra-low-height hydraulic jacks.
What Is a Low-Profile Hydraulic Cylinder?
The low-profile hydraulic cylinder is a specialized design of the hydraulic lifting devices. This particular kind of cylinder delivers high lifting capabilities with a small closed height. With its compact structure, this unit proves to be useful for situations where there’s limited space between the load and its supporting surface.
Unlike conventional hydraulic cylinders that need more clearance for their setup, low profile units can be situated underneath machinery, structural elements, as well as hefty weights where space is at a premium. In cases where an exceptionally compact form factor is needed, using a low-profile RAM will allow for precise raising of stuff within a rather short travel range whilst ensuring the necessary power output for various industrial purposes.
For instance, BEMCO JACKS has manufactured many different types of hydraulic jacks which have been engineered to work with heavy equipment lifting, alignment, and clamping in space-constrained applications. Flat Hydraulic Jacks From Bemco Jacks.
How Does a Low Profile Hydraulic Cylinder Work?
The Working principle of a low profile hydraulic cylinder operates by applying the hydraulic pressure as per Pascal’s law.
In simple words, this hydraulic system can apply hydraulic fluid under pressure to move the pistons or ram inside the cylinder.
The basic operating process involves:
- Generate hydraulic pressure: A hydraulic pump that’s part of the system will pressurize the hydraulic oil as long as there’s a connection between them.
- Oil enters the cylinder. Pressurized oil then goes into the chamber of the cylinder.
- Piston move– Finally, the oil exerts its force upon the piston surface, resulting in a linear motion.
- Load is Lifted – The generated force lifts the piston/ram upwards, causing the associated load to be raised.
- Ram Returns – Based on the design, this can happen due to spring, gravity, or other hydraulic actions.
- Amount of Lifting Force – The amount of force created can depend on many things, but it generally provides adequate force within a relatively small space.
The amount of lifting force depends on factors such as hydraulic pressure and piston area. This allows relatively compact equipment to generate significant lifting force.
Key Features of Low Profile Hydraulic Rams
The biggest advantage of low profile hydraulic rams is their ability to combine compact dimensions with high lifting capability. However, their usefulness extends beyond their small size.
Compact Construction
Their short, closed height makes them suitable for applications where conventional cylinders cannot be positioned easily.
High Lifting Capacity
A compact design does not necessarily mean low lifting performance. BEMCO JACKS’ flat hydraulic jack range, for example, covers capacities from 10 to 100 tons, with strokes ranging from 12 to 25 mm.
Controlled Lifting
Hydraulic operation allows operators to achieve controlled and precise lifting, which is important for alignment, positioning, and maintenance work.
Durable Construction
BEMCO JACKS manufactures its flat jacks from high-grade, hardened, and tempered alloy steel. Exposed surfaces are hard chrome plated and blackodized to provide corrosion protection.
Customizable Solutions
Different lifting applications have different space, capacity, and stroke requirements. Customized hydraulic solutions can therefore be developed for specialized industrial applications.
Low Profile Hydraulic Cylinder vs. Standard Hydraulic Cylinder
The primary difference is the available installation space.
A standard hydraulic cylinder is suitable when sufficient clearance exists beneath the load. A low height hydraulic cylinder, on the other hand, is designed specifically for restricted-clearance applications.
This makes low-profile models particularly useful for:
- Lifting machinery from a low starting point
- Positioning heavy equipment
- Structural alignment
- Maintenance and repair operations
- Clamping applications
- Industrial installation work
For extremely restricted spaces, BEMCO JACKS also offers ultra-low-height single-acting hydraulic jacks. Its plain-ram models have closed heights starting from 105 mm and are designed for applications such as segment or girder lifting and lowering.
What Is a Low Profile Hydraulic Jack?
A low profile pancake hydraulic jack is a particularly compact hydraulic lifting solution characterized by its short height and broad, relatively flat design.
These jacks are useful when the available clearance is extremely limited and a conventional hydraulic cylinder cannot be installed.
BEMCO JACKS’ flat hydraulic jacks are designed for heavy equipment lifting, alignment, and clamping. Depending on the model, the range offers capacities between 10 and 100 tons and maximum operating pressures of up to 700 kg/cm².
The pancake-style configuration can therefore be valuable when both high lifting force and minimal installation height are important.
Applications of Low Profile Hydraulic Cylinders
A low profile hydraulic cylinder can be used across industries where heavy loads must be lifted or positioned from a restricted starting height.
Heavy Equipment Lifting
Compact hydraulic cylinders can be positioned underneath machinery and equipment where ground clearance is limited.
Alignment and Positioning
Hydraulic force can help align heavy components during installation, maintenance, and assembly operations.
Structural Work
Low-profile and ultra-low-height hydraulic jacks are used for lifting and lowering structural components such as segments and girders.
Clamping
Flat hydraulic jacks can also be used for clamping applications where compact dimensions and controlled force are required.
Maintenance and Repair
During heavy equipment maintenance, a low starting height can make it easier to position the lifting device beneath the component requiring service.
Benefits of Using a Low Height Hydraulic Cylinder
Choosing a low height hydraulic cylinder can offer several practical benefits:
Works in restricted spaces: Its compact, closed height allows installation where conventional cylinders may not fit.
Efficient heavy lifting: Hydraulic pressure provides substantial lifting force without requiring a large mechanical structure.
Improved positioning: Controlled hydraulic movement supports accurate lifting and alignment.
Versatile applications: These cylinders and jacks can be used for lifting, alignment, clamping, maintenance, and structural work.
Built for demanding environments: High-grade alloy steel construction and protective surface treatments can improve durability in industrial conditions.
How to Choose the Right Low Profile Hydraulic Ram?
Before selecting a low profile hydraulic ram, consider the requirements of your application.
Load Capacity
Select a cylinder with sufficient rated capacity for the load. Never exceed the manufacturer’s specified safe working limits. BEMCO JACKS recommends operating its flat jacks at 80% of the rated capacity as a safe practice.
Closed Height
Measure the available clearance before selecting the cylinder. This is one of the most important factors when working in confined spaces.
Stroke Length
Determine how much lifting movement is required. Flat hydraulic jacks typically provide short strokes, making them suitable for applications where controlled, incremental lifting is needed.
Operating Pressure
Ensure the cylinder and hydraulic system are compatible with the required operating pressure.
Application Requirements
Consider whether you need the equipment for lifting, alignment, clamping, structural work, or another specialized task. The correct design will depend on the specific application.
