Narrow Pallet System:



Problem: One Solution:
Carrying heavy boxes by hand is strenuous
and awkward.
Roll a stack of boxes with a hand pallet truck.
hand carrying heavy loads can cause back strain
Carrying loads up to 75+ pounds is tiring. Carry loads of 500+ pounds with less effort.
Can only move four boxes at once. Can move up to 16 boxes at once.
Awkward carrying positions. Allows loads to be rolled.
Must stoop, bend, and lift often. Less stooping, bending, and lifting.
Poor handles on boxes. Better carrying grip, lower weight at
handles.



Narrow Pallet System

What Is a Pallet Truck?

Pallet trucks are similar to regular hand trucks (dollies) with the exception of having pivoting forks instead of a plate metal shoe. If you stack your load on a small pallet (14"x24"), you can position the forks underneath and roll away as many as 16 5/9 bushel boxes. A pallet truck can be tilted (by releasing the forks) for loading and unloading and locked into an upright position to tip back and roll the load.

Why Not Use a Regular Hand Truck?

With a hand truck, you need to push a stack of boxes forward in order to squeeze the shoe under the stack. This can make the stack unstable. A pallet system keeps the load upright and stable until the truck is locked into position for moving. The shoe of a regular hand truck is fixed, which limits its use in tight quarters. Standard stackable containers tend to slide around on a regular hand truck when full because the bottom of the container has a smaller footprint than the top. But using a pallet underneath the standard containers, you eliminate the sliding.

Why Not Use a Regular Pallet?

Many small-scale growers store and pack produce in converted barns, older buildings, and coolers with tight spaces and narrow doorways. A full-size pallet and pallet jack require a very flat, smooth, hard surface to roll easily. Pallet trucks, with their narrow size and pneumatic wheels, roll easily through doorways and on rough surfaces.

How Much Time and Energy Will It Save?

There are several ways a pallet truck can increase your efficiency compared to moving boxes by hand.

  1. The number of times you lift or lower a box can be cut in half.
  2. If you would normally carry 3 or 4 boxes at a time, you can cut your total number of trips by 75%-82%.
  3. By using a pallet truck you can cut the time you spend carrying boxes by 60%.

Cost Analysis

A new custom-made pallet truck with pallets costs $750. At $7.00/hr., you'd need to save yourself 143 hours for the system to pay for itself. Ten hours saved per month (30 minutes per weekday) means the system pays for itself in a little over 14 months of use. If you commonly visit a chiropractor or massage therapist to relieve back pain, the pallet truck system can pay for itself in less than 12 visits (at $50/visit).

Where Can I Find a Pallet Truck?

Pallet trucks are commonly used for feed and seed sacks. Look in feed mills and co-ops for used pallet trucks which you can retrofit with a larger back frame to support two stacks of boxes. Valley Craft makes pallet trucks with the wider frame; these trucks are distributed by several dealers. Look under "materials handling" in your phone book or contact the following companies.
