How Does an Electric Pallet Truck Work?

Press the Handle, the Load Rises – What Happens Behind the Scenes?

When you press the lift button on an electric pallet truck‘s handle and the forks smoothly raise a pallet off the ground, have you ever wondered: what actually happens behind this “effortless” action?

From battery discharge to motor rotation, from hydraulic oil being pressurized to the forks rising precisely, the working principle of an Electric Pallet Truck is a sophisticated electromechanical-hydraulic collaborative system. This article will break down this process and help you understand the core components and working logic of an electric pallet truck.

1.Power Source: How Does the Battery Power the Entire Vehicle?

The starting point of all actions is the battery.

Electric pallet trucks are typically equipped with lead-acid batteries or lithium batteries (Li-ion). When you turn on the power switch, the battery supplies power to the following systems:

The battery voltage determines the vehicle‘s power platform. Common voltages include 24V, 48V, 80V, etc. Higher voltages generally support greater load capacities and higher lifting heights.

Take Diding Lift‘s 2T Stand On Pallet Truck Off Road CBDE as an example. This model supports an optional lithium battery upgrade, offering 2-hour fast charging, opportunity charging, and a 2000-cycle lifespan. It also comes with a built-in charger, eliminating the need for a dedicated charging room with plug-and-play convenience.

2.Travel System: How Does the Motor Drive the Wheels?

When you rotate the accelerator on the control handle, the signal is transmitted to the drive motor controller. Based on the rotation angle, the controller outputs a corresponding amount of current to the drive motor.

Drive motor rotates → Gearbox amplifies torque → Drive wheel turns → Pallet truck begins moving.

Electric pallet trucks primarily use two types of drive motors:

AC motors have become the mainstream choice. They have no brush wear issues and offer higher energy recovery efficiency.

3.Steering System: How Is Precise Turning Achieved?

Electric pallet trucks use two steering methods:

3.1  Mechanical Link Steering

Turn the control handle → Linkage directly drives the drive wheel to pivot → Vehicle turns. Advantage: simple structure, direct response. Disadvantage: steering effort increases with load weight.

3.2 Electric Power Steering

Turn the control handle → Angle sensor detects steering intention → Steering motor actively assists in pivoting the drive wheel. Advantage: steering effort remains light regardless of load. Disadvantage: slightly higher cost.

Regardless of the method, electric pallet trucks have a much smaller turning radius than traditional forklifts. The 2T Stand On Pallet Truck Off Road CBDE has a turning radius of only approximately 1.5 meters, allowing flexible operation in aisles 2.0-2.5 meters wide.

4.Lifting System: How Do the Forks Raise the Load?

This is one of the most core functions of an electric pallet truck. The lifting system consists of the following components working together:

Lift motor (hydraulic pump motor) → Hydraulic oil pump → Hydraulic oil is pressurized into the lift cylinder → Cylinder piston rod extends → Forks rise

When you press the “lift” button, the lift motor drives the hydraulic oil pump to rotate at high speed, drawing hydraulic oil from the reservoir, pressurizing it, and sending it into the lift cylinder. The piston inside the cylinder moves upward under oil pressure, pushing the forks to rise.

When lowering: The system uses a solenoid valve to control the hydraulic oil as it slowly returns from the cylinder to the reservoir. The forks lower smoothly under gravity, with speed adjustable via valve opening to prevent slamming.

5.Control Handle: The Brain and Nervous System of the Vehicle

The control handle is the interface between the operator and the pallet truck. Modern electric pallet truck handles integrate the following functions:

Take the 2T Stand On Pallet Truck Off Road CBDE as an example. Its emergency reverse button automatically stops and reverses the equipment if an obstacle or person is detected while reversing, greatly reducing collision accidents. Additionally, the electromagnetic brake system ensures automatic braking when the handle is released on slopes, preventing rollback.

6.Braking System: How Does It Stop Safely?

Electric pallet trucks typically use an electromagnetic brake principle:

When you are driving normally, the electromagnetic brake is in a “released” state, allowing the drive wheel to rotate freely.

When you release the control handle or squeeze the brake lever, the controller cuts power to the drive motor, and a spring inside the electromagnetic brake presses friction pads against the brake disc, stopping the drive wheel.

The advantage of this design is: braking when power is cut. Even if the vehicle loses power unexpectedly, the brake automatically engages, preventing rollback.

7.Whole-Vehicle Coordination: A Complete Operating Cycle

Putting the above systems together, a complete handling cycle looks like this:

Start: Turn on power; battery supplies power to all systems

Travel: Rotate accelerator; drive motor turns; vehicle moves forward

Steer: Turn handle; drive wheel pivots; change direction

Position: Insert forks under the pallet

Lift: Press lift button; hydraulic system activates; forks raise pallet approximately 10-15cm off the ground

Transport: Drive to destination

Lower: Press lower button; forks lower smoothly to the ground

Exit: Reverse out from under the pallet; ready for next cycle

8.Core Components Summary

Why Is Understanding the Working Principle Important?

Understanding how an electric pallet truck works not only helps you operate it correctly and extend equipment life, but also allows you to quickly diagnose problems when failures occur. For example:

Poor battery life → Possible charging habit issue, or need to upgrade to lithium battery

Weak travel → Possible drive motor or controller failure

Slow lifting → Possible low hydraulic oil level or worn pump

Brake failure → Check the electromagnetic brake system
