What is a Pallet Jack
The pallet jack, also named manual hydraulic pallet truck, is a compact, convenient, flexible, heavy-duty, and durable cargo handling tool. In addition to the function of consigning goods, the pallet jack contains a hydraulic device between the chassis and the wheels in order to facilitate the lifting and lowering of the goods.
The manual pallet jack can be easily pushed under the base of the cargo box, and then the chassis is lifted by hydraulic pressure. Thus can drag the cargo to move. After reaching the destination, the chassis will be lowered hydraulically. And then the cargo will land accordingly and the pallet jack can be easily drawn out. As a result, the hand pallet jack can help to omit the complicated process of manual handling.
How does Pallet Jack Work
The hydraulic principle of manual pallet jack:
The large oil cylinder (9) and the large piston (8) form a lifting hydraulic cylinder. A lever handle (1), a small cylinder (2), a small piston (3), two one-way valve (4) and (7) form a manual hydraulic pump.
When you lift the handle to move the small piston upward, the volume of the oil chamber at the lower end of the small piston will increase. Thus forms a partial vacuum. At this time, the one-way valve (4) is opened and the oil is sucked from the oil tank (12) through the suction pipe (5); Then press the handle downwards. The small piston moves down, and the pressure in the lower chamber of the small piston increases. As a result, the one-way valve (4) is closed, the other one (7) is opened, and the oil in the lower chamber is input into the lower chamber of the lifting cylinder (9) through the pipe (6). Thereupon, forcing the big piston (8) to move upwards to lift the heavy objects.
When the handle is lifted again to suck in the oil, the one-way valve (7) is automatically closed to prevent the oil from flowing back. Thereby ensuring that the heavy object will not fall by itself. By continuously pulling the handle back and forth, the oil can be continuously pumped into the lower cavity of the lifting cylinder to gradually raise the weight. If the shut-off valve (11) is opened, the oil in the lower cavity of the lifting cylinder flows back to the oil tank through the pipe (10) and the shut-off valve (11), and the heavy object moves downward.
How Much does a Pallet jack Weigh?
The weight of the pallet jack is generally 35-55kg.
You can choose the suitable model according to different your working conditions.
How Much Weight Can I Pull on a Pallet Jack?
The carrying capacity of the hand pallet jack is around 1.0 – 5.0 tons.
Generally speaking, the international standard has 4 kinds of deadweight: 2.0t-2.5t-3.0t-5.0t.
You can choose the suitable model according to different your working conditions.
How to Fix a Manual Pallet Jack?
The reasons why the forks of manual pallet jack cannot be lifted can be summarized as the following four common reasons:
1. No hydraulic oil;
2. The purity of the oil is not enough;
3. The adjusting bolt is too close or the adjusting screw is too tight so that the valve keeps on open status;
4.There is air in the hydraulic cylinder.
The methods to solve the above problems:
1. Add oil;
2. Change oil;
3. Vent air.
The above are some small problems often encountered in the use of manual pallet jacks.

Should You Push or Pull a Pallet Truck?
Generally, it is safer to push than pull. At the same time, the push is more effortless than pull. Because when pushing, you have two feet as a fulcrum.
However, you should pay attention to special situations, such as on slopes.
It is safer to pull than push, in order to avoid the pallet jack running out of control and hitting people due to the excessive speed caused by inertia.

Once you have determined that Yide Foundry is a manufacturer that meets your requirements. Then, the next step is to collect the informations of the product.
Custom metal casting is a complex process. The success depends on the communication and detailed control of the entire process.
You should consider the following information in your request for quotation.
Please provide the drawings and specifications of the casting, including (but not limited to):
- Dimensions and geometry
- Acceptable dimensional tolerances
- Stress / load requirements
- Machining requirements
- Non-destructive test requirements
Please send the information to [email protected]
You can list specific metal grades, preferred materials or required properties.
Due to the inherent cost of the metal/alloy and its castability, the cost is greatly affected by the material selected.
Actual or estimated weight
Used to calculate the cost of purchasing materials, processing and transportation. Actual weight is preferred because inaccurate estimates may cause discrepancies between estimated and actual costs.
If existing mould is available, casting costs can be reduced.
If not, the design of the mould will constitute the main cost. Paying higher fees for complex mould can reduce casting costs and improve casting quality.
Include current and future expected quantities. The quantity has a great influence on production methods, tool development and total cost.
Casting surface finish (smoothness) requirements, material performance test standards and casting robustness are all key considerations for quotation.
ASTM provides the tools necessary to establish inspection standards. Most mechanical tests are performed on representative test rods.
Additional non-standard inspection requirements increase the cost of casting.
It can be expedited, but it will also increase the cost
Yide Foundry can provide secondary processing operations:
- Heat treatment
We prepare and package all products to protect them during transportation and storage.
Special requirements will increase the cost of transportation and must be notified in advance.
Through communication with our professionals, we can best understand the functions and costs of castings. Our casting experts will work with you to outline product solutions and help you realize them in the most economical way.

How to Cast Pallet Jack Parts
Pallet Jack Parts are generally ductile iron parts.
Because the ductile cast iron has high strength feature, and with good plasticity and toughness, which can fully exert the performance of the substrate.
Ductile iron castings are solid metal objects that result from molten ductile iron being poured into voids in a mold.
The ductile iron subsequently cools and solidifies in the shape of the void it occupies.
How to Replace Pallet Jack Wheels
First of all, make sure that the replacement wheels is the same size as the original ones.
Then, knock off the cotter pin with steel nails and drive out the axle.
Next, take the old wheels off in order, and then install the new wheels in the exact reverse order.
If the wheel is rusty, you need to find a hard striker, punch out the hollow pin of the wheel and the axle, and then knock out the small axle, and replace the wheel together with the bearing.
How Do You Put Hydraulic Fluid in a Pallet Jack?
There is a threaded bulkhead near the upper end of the hydraulic cylinder of the pallet jack.
Unscrew the bulkhead, you can find the oil filling hole.
The hydraulic oil should be selected according to the grade specified in the “Instruction Manual”.
When a substitute oil is needed in special circumstances, the property should be the same as the original grade.
Different brands of hydraulic oil cannot be mixed to prevent chemical reactions and property changes of the hydraulic oil.
The hydraulic oil must be filtered before filling, and the refueling tools must be clean.
Do not remove the filter at the opening. Fueling personnel should use clean gloves and work clothes to prevent solid impurities and fiber impurities from falling into the oil.
