A dump trailer hydraulic telescopic cylinder is a special type of hydraulic cylinder designed for trailer dumping. It is usually three-stage, meaning it has a main barrel, middle barrel, and rod barrel. It works by connecting the hydraulic pump and the hydraulic pipe. When the hydraulic pump provides the oil, the oil will flow to the oil inlet of the cylinder through the hydraulic pipe. The oil will push the piston rod to extend out, and then the trailer dumping goods will extend up. The middle barrel will then follow, and finally, the third rod barrel will also follow to further increase the height of the dump trailer.
Since this type of hydraulic cylinder has a three-stage barrel system, it can lift very heavy weights, which means they are suitable for off-road trucks and other vehicles that have a heavy load capacity. It is also suitable for those that have a high load requirement because it can be installed on vehicles that are designed with a high foundation.
Some other common types of telescopic cylinders include the following:
Double Acting Telescopic Cylinder:
This cylinder features multiple stages or sections that slide within each other. They are distinguished by moving in two different directions, which is to extend and retract, and they are usually powered by hydraulic pressure.
Single Acting Telescopic Cylinder:
Joy Stick Controlled Telescopic Cylinder:
These types of telescopic cylinders are commonly found in vehicles that have a great level of sophistication, such as heavy-duty trucks and special vehicles. They usually utilize electronic control and can be operated through joystick control functions.
The specifications of a hydraulic dump trailer cylinder may vary depending on the individual or custom-made models. However, the following are some of the general specifications one may find when researching the product:
Sizes and capacities
The dump trailer cylinders usually have different sizes, which affect their capacities. The most common sizes available are 4-inch, 5-inch, and 6-inch bores with a stroke length of up to 60 inches. Customers usually choose certain sizes and capacities depending on the dump trailer's size and the material being transported.
Pressure ratings
Hydraulic Dump trailer cylinders usually have valves, seals, and pressure ratings that allow them to work under high pressures. The pressure rating is indicated in pounds per square inch (psi). A 5-ton dump trailer, for instance, might have a pressure rating of 2,000 psi, which is sufficient to handle the pressure from the hydraulic pump connected to the trailer's system.
Material
Manufacturers produce dump trailer hydraulic cylinders using various materials, such as plastic and metal. Most of the time, the cylinder body consists of robust alloys or steel materials designed to withstand punishing conditions and cope with high pressure without bending or breaking.
An improperly maintained hydraulic dump trailer cylinder can break down, leaving the owner to incur unnecessary costs. Sticking to a maintenance schedule is important, as it can increase the lifespan of the hydraulic cylinder and its functionality.
Frequent cleaning
Regular cleaning of the hydraulic cylinder helps to maintain its condition and appearance. Operators can clean the cylinder by washing off any foreign debris or materials in the garden hose or pressure washer. They should avoid using excessive pressure to prevent damage to the seals.
Keep it Lubricated
Dump trailer hydraulic cylinders usually have moving components, such as pins and bushings, that require lubrication to work efficiently. Lubricating them reduces friction between the moving parts, minimizing wear and tear. Doing this extends the lifespan of the hydraulic cylinder.
Routine Inspection
Operators can maintain the hydraulic cylinder's optimum performance and functionality by routinely inspecting it for damages. The inspection process should be thorough, and the operator should pay attention to visible linkage areas, seals, hoses, and valves.
Hydraulic Oil Change
The oil changes are crucial to keeping the dump trailer hydraulic cylinders in great condition. Hydraulic oil can get contaminated over time due to debris and dirt buildup, affecting the performance of the cylinder. Regular changing can prevent this and prolong the cylinders' lifespan.
Hydraulic cylinders are crucial components of many industries and applications because they convert hydraulic energy into mechanical power to move trains. Some of these industries include the construction, mining, and material handling industries, all of which utilize telescopic cylinders for the following:
Transporting Heavy Materials
Dump trailer hydraulic cylinders have the footing necessary to move bulk loads and weights of heavy materials like ores, gravel, sand, and stones. They also have great stability to last long while loading these materials faultlessly. Additionally, they are compatible with all kinds of transportation methods, either land or fluvial.'
Mining Industry
In the mining industry, telescopic cylinders are mainly used in dump trucks and excavators. These trucks are constructed with a special function to tilt the dumping trailer by using a telescopic hydraulic cylinder for an upward movement. The material is thus easily, quickly, and efficiently transported or loaded. Sand, gravel, ore, and other similar materials are handled easily and efficiently with telescopic cylinders with high flexibility and suitable pressure resistance. As a result, no damage is done to the material, and the equipment is not worn out.
Meanwhile, telescopic cylinders in excavators are responsible for tasks like loading heavy materials such as ores and stones from the mining site into trucks or containers. In fact, they are capable of achieving high lifting heights, which is important for loading operations. Moreover, hydraulics offer high stability and pressure, making it safe and secure when moving and handling heavy materials.
Construction Industry
Dump trailers are mostly used during the transportation of heavy construction materials like cement, stones, gravel, sand, etc. Whether it is an excavator, backhoe, or loader used at a construction site, they all have a telescopic hydraulic cylinder, which enables them to easily and efficiently move and stack materials.
When selecting a hydraulic dumper trailer cylinder, one must focus on a few key factors to ensure a good performance match for the intended use.
Cylinder's Material and Finish
Trailer dumps operate in challenging environments. Therefore, the material of the telescopic hydraulic cylinder and its finish are critical. The commonly used materials for these cylinders are carbon steel and stainless steel. Carbon steel offers good strength but may be prone to rust. Choosing carbon steel with a protective anti-rust coating can enhance durability. On the other hand, stainless steel is naturally resistant to rust. It can survive in dump trailers exposed to damp or corrosive environments. The choice of material also impacts costs. Businesses should evaluate operating conditions and budget constraints to select an appropriate cylinder material.
Cylinder's Seal Design
Cylinder seals are barrier components that prevent oil leakage by forming a tight seal between the movable parts. They also prevent dirt ingress. Seal designs differ based on the application. Dump trailers operate under high loads and rough conditions. Therefore, choosing a seal that can withstand these demanding scenarios is vital. Seals made robustly for high-load applications will perform reliably. They will minimize oil spillages and prevent dirt ingress, ensuring the longevity of the cylinder.
Adjustable or Non-Adjustable Tolerance Ends
Trailer dump telescopic cylinders produce movements by sliding cylinder parts called tolerance ends. These tolerance ends experience wear over time and may need adjustments to revive their performance. Some cylinders have adjustable tolerance ends, while others are non-adjustable. Non-adjustable tolerance ends may require complete cylinder replacement after wear, resulting in higher maintenance costs. Although not adjustable, non-adjustable cylinders may perform adequately in some applications. Consider dump trailers that operate under excessive loads and rough conditions. For such demanding applications, selecting cylinders with adjustable tolerance ends may be more cost-effective in the long run.
Cost-Saving Through Rebuildable Cylinders
A typical maintenance procedure for a hydraulic cylinder involves replacing its seals and bladder. Most undergo this seal and bladder replacement process at hydraulic repair shops. However, some cylinders are designed to be rebuilt in-house, which may reduce repair costs significantly. These rebuildable cylinders can be serviced internally, eliminating costs associated with external repairs. Choosing rebuildable cylinders has the added advantage of reducing downtime. The cylinder replacement and repair process happens faster internally than externally. Businesses can save costs and improve operational efficiency by selecting rebuildable cylinders.
Q1: What are the types of dump trailer hydraulic cylinders?
A1: There are three main types of cylinders commonly used in dump trailers: single-stage cylinders, double-stage cylinders, and triple-stage cylinders. The single-stage cylinder can only extend and lift items to a certain height. While the second double-stage cylinders have two contained inner pipes, the triple-stage, or we could say the multi-stage cylinders work similarly to the double-stage cylinders, but they have more inner pipes.
Q2: What are the advantages of dump trailer hydraulic cylinders?
A2: Hydraulic dumps trailer cylinders are strong compression devices that use hydraulic pumps to push or pull their shafts. They are liftable and able to bear heavy weights, which makes them ideal for use in dumping trailers. They can be custom manufactured to suit any specific requirement. Their shafts are exchangeable.
Q3: What are the materials of dump trailer hydraulic cylinders?
A3: The cylinder head and base of a hydraulic cylinder are usually made of cast iron for strength and stability, as they need to hold the seals and bearings that support the piston. The piston rod is typically made of stainless steel, which offers good corrosion resistance and can be easily cleaned and polished.
>Q4: How does a dump trailer hydraulic cylinder work?
>A4: Hydraulic cylinders work on the principle of hydraulics, where fluid pressure is used to create motion. They consist of a cylinder, a piston, and connecting ports. The hydraulic pump delivers oil to the cylinder through hoses and fittings. The oil enters the cylinder and pushes the piston, which creates motion. The direction of motion is determined by the type of valve used in the system.
