Pallet truck

Description

A pallet truck, also known as a pallet jack, pump truck, jigger, or stacker (though “stacker” can also refer to a powered device), is a basic tool designed to lift and move pallets. Here’s a breakdown of what it is and its key features:

What it is?

Manual Material Handling Equipment
It’s primarily a manual tool, meaning it’s operated by human power.
Lifts Pallets
Its main function is to raise a pallet a few inches off the ground.
Moves Pallets
Once lifted, it allows the operator to easily push or pull the pallet to a new location.

Key Components and How it Works:

Forks (or Tines)
These are the two horizontal arms that slide under the pallet. They are typically made of sturdy steel.

Handle/Pump Lever
This is what the operator uses to control the lifting and lowering mechanism.
- Pumping Action
  By repeatedly pumping the handle up and down, hydraulic fluid is forced into a cylinder, extending a piston and lifting the forks.
- Lowering Lever
  A separate lever on the handle controls the release of hydraulic pressure, allowing the forks to descend.
Wheels
- Steering Wheels
  Located at the rear of the truck, these allow the operator to steer the pallet truck.
- Fork Wheels (or Load Wheels)
  These are smaller wheels attached to the ends of the forks. They bear the weight of the pallet and its contents and roll along the ground.

Hydraulic System
This is the core of the lifting mechanism. It uses hydraulic fluid to convert the operator’s pumping effort into the force needed to lift the pallet.
