The side loader garbage truck is a remarkable piece of engineering, designed with efficiency and hygiene in mind. The truck's unique design, which includes a hydraulic cylinder, allows it to handle large volumes of trash with ease. The hydraulic cylinder in a side loader is made up of 2 main parts: the cylinder tube and the piston. The cylinder tube is a hollow metal cylinder that contains the hydraulic fluid. The piston is a CHINAMFG metal rod that slides within the cylinder tube.  The hydraulic cylinder is the driving force behind the side loader garbage truck's capabilities. It powers the lifting and tilting mechanisms that are essential for emptying trash containers into the truck's body. The cylinder uses pressurized hydraulic fluid to generate the force necessary to manipulate the trash container.

Hydraulic Cylinder used on Rear Loader
The rear loader garbage truck is a specialized vehicle designed to handle the collection and disposal of trash in an efficient and hygienic manner. It features a unique loading mechanism that allows trash to be emptied directly into the truck's body from the side, rather than from the rear or top.The hydraulic cylinder is what powers the trash container lifting mechanism. It uses pressurized hydraulic fluid to generate the force needed to tilt and empty the trash container into the truck's hopper. This design allows for quick and effortless emptying, reducing the time and effort needed for trash collection.The hydraulic cylinder in a rear loader must be able to withstand significant forces and pressures, as it is responsible for lifting heavy loads and repeatedly performing this task over time.

Hydraulic Cylinder Producing Process

Step1: Quality Control on Raw Material
We have our own lab in factory, inspect the raw material and do the test. For every batch of material we received, we will ask supplier provide their certificate, and then cut them to do the test again to see if the results match the certification. Also, every batch we received, we will cut them into pieces to check the air bubbles. Once they are all qualified, we will accept it, and all detail information will be recording in our ERP system. We will also pay lot of attention on the salt spray test for chrome rod. Every month, we will cut the material, put them into test machine to see if it reach the requirement. All the result will be recorded at our QC department. If customer need, we can provide it.

Step2: Quality Control on Machining

we start doing components machining from 1988 with 36 years experience now and insist doing 100% inspection. We spend lots of money, invest on auto robots and machines. Now half of the producing line is by robot so that we can ensure our quality be stable good. For every part of the cylinder, we do 3 times inspecting. Firstly, workers will do self inspection. Secondly, we have tour-hour inspection checking the products, 2 times in the morning and 2 times in the afternoon, make sure that every step is good. After the products are all completed, we will do 100% inspection. For thread, for the tolerance, everything, we need double check. Also, we have specific warehouse just for the measuring tools. Every inspector have their own measuring tool and we will check the measuring tools regularly to make sure they are all in good condition, so that the measuring results will be convincing.

Step3: Quality Control on Welding

We are qualified to AWS certification, which is very popular in North American market. First, for the visual test, we will make sure that every components are welded good, look beautiful. And the second, we need to check the penetration. We have more than 15 years experience, we do know what kind of designing angle can make the cylinder welding strong. Once we finish the first article, we will cut it and analyse the welding to see if it is fulfill the groove. And then do the radiographic testing to make sure there is no gap inside. What's more, we will do the ultrasonic test to check the program for the robot. Now 80% of welding is doing by robot. Once the program confirmed, no 1 can change it unless the welding manager, and they only have 5% right.

Step4: Quality Control on Assembling
For assembling, we have some difference with others. The brand we uses for seals are all those famous brand like Aston, Parker, Hallite. The cylinder we give to our customer has 2 years warranty. For our company, we engrave our part number and manufacturing date for the quality warranty. So no matter for seals or any others, as long as they are parts of cylinder, if it is under 2 years, we will take responsibility for them. And we will do the test for every cylinder like for pressure after we finish assembling.

Step5: Quality Control on Painting
We have our half auto painting line. Right now, we can paint about 1500 cylinders per day, which is about 1 container. Before we do the painting, we will do the wash first and for every cylinder, we will test for hardness, thickness and adhesion to make sure the painting are all good, which will be recorded into OQC report, print out and stick on the box, ship to you with your products.

Step6: Hydraulic Cylinder Packing
For every cylinder, we have the stick to show the detail information like bore size, stroke and working pressure. And we will use individual plastic bag packing. If customer need, we can also use individual carton box packing. We will fasten 1 floor after 1 floor with plat, so customer can only cut what they need and other layer will still be fasten. Moreover, there will be plywood pallet or plywood box for customer choosing. We will also send the loading picture to customer after we ship them to make sure everything is well loaded in China.
