Why Won't My Pallet Jack Go Up: A Comprehensive Guide


Pallet jacks are an essential tool for material handling in warehouses, factories, and other industrial settings. They help streamline operations by efficiently moving heavy loads. However, encountering issues with pallet jacks can be frustrating, especially when they refuse to go up. In this article, we will explore the common reasons behind this problem and offer practical solutions to get your pallet jack functioning smoothly again.

Understanding the Basics:

Before delving into the reasons why your pallet jack may not be lifting, it's important to understand its basic functioning. A pallet jack operates on a hydraulic lifting system. An operator uses a handle to pump hydraulic fluid into the jack, which in turn raises the forks to lift the load. This hydraulic system is powered by either manual pumping or an electric motor.

Subheading 1: Improper Fork Positioning

One common reason why a pallet jack won't go up is improper fork positioning. The forks need to be positioned at the correct angle and fully inserted under the load. This ensures that the weight is distributed evenly, allowing the hydraulic system to function optimally. If the forks are not correctly positioned, the jack may struggle or refuse to lift the load.

To resolve this issue, ensure that the forks are aligned correctly with the pallet. Double-check that the forks are fully inserted and evenly spaced. If the load is too heavy or imbalanced, you may need to redistribute the weight or use alternative lifting equipment.

Subheading 2: Low Hydraulic Fluid

Another common culprit behind a pallet jack's failure to go up is low hydraulic fluid. The hydraulic fluid is responsible for transferring pressure from the pump to the lifting mechanism. If the fluid level is inadequate, it can cause a loss of pressure and hinder the lifting process.

To address this problem, check the hydraulic fluid level in the pallet jack. If it's below the recommended level, refill it with the manufacturer's suggested fluid. Be cautious not to overfill, as it may lead to other operational issues. Regularly monitoring and maintaining the hydraulic fluid level will help ensure smooth operation.

Subheading 3: Damaged or Worn Out Seals

Worn-out or damaged seals within the hydraulic system can also cause a pallet jack to struggle while lifting. Seals prevent fluid leakage, maintain pressure, and keep the hydraulics functioning properly. Over time, seals may deteriorate due to wear and tear, leading to a loss of pressure, and consequently, the jack's inability to lift loads.

If you suspect that seal damage is causing the problem, it's advisable to consult a professional technician. They can inspect and replace the damaged seals to restore the pallet jack's lifting capabilities. Regular maintenance and seal replacements at recommended intervals can prevent these issues from occurring.

Subheading 4: Malfunctioning Pump or Motor

A malfunctioning pump or motor can significantly affect a pallet jack's lifting capacity. In electric pallet jacks, an issue with the motor may cause a lack of power, resulting in the jack's failure to lift. Similarly, in a manually operated pallet jack, a faulty pump can hinder the flow of hydraulic fluid, thereby preventing the lifting mechanism from functioning correctly.

In such cases, it is advisable to seek professional assistance. An experienced technician will be able to diagnose the problem and repair or replace the faulty pump or motor, restoring the jack's lifting capability.

Subheading 5: Overloaded Pallet Jack

Finally, overloading the pallet jack beyond its weight capacity is a common mistake that can lead to lifting issues. Each pallet jack comes with a specified maximum weight capacity that should never be exceeded. Overloading not only damages the jack itself but can also pose serious safety risks. Exceeding the weight limit puts excessive strain on the hydraulic system, making lifting difficult or impossible.

Ensure that you are aware of the weight limits specified by the manufacturer for your pallet jack model. If you consistently need to handle heavier loads, consider investing in a pallet jack with a higher weight capacity or explore alternative lifting options.


When faced with a pallet jack that refuses to go up, troubleshooting the problem can save time and money. By paying attention to proper fork positioning, hydraulic fluid levels, seal integrity, and the pump or motor condition, you can identify and resolve common issues that hinder the jack's lifting capability. Additionally, awareness of weight limits prevents overloading, ensuring the longevity and efficient operation of your pallet jack. Regular maintenance and prompt repairs will help keep your pallet jack functioning smoothly, optimizing material handling operations in your facility.
