More than 500,000 forklifts are
powered by propane in factories and warehouses. And it's no wonder.
Propane-powered forklifts provide operational options and economic
advantages that make them a clear choice for your material handling
needs.
The
reasons for choosing propane forklifts and for converting existing
gasoline forklifts to operate on propane are plentiful.
|
|
|
Environmentally Friendly: Propane is a
non-toxic,
clean-burning fuel that can be used to safely power forklifts both
indoors and outdoors. With propane, there is no spillage loss or
evaporation into the atmosphere.
|
|
Safe: Propane forklift tanks, fuel lines and carburetion
components meet or exceed strict specifications. Built-in safety
devices automatically shut off the flow of fuel in case of an
accident.
|
|
Versatile: Propane forklifts can be used in indoor and
outdoor applications. Propane is the most portable fuel �
cylinders can be stored and moved virtually anywhere within a work
site.
|
|
Strong: Propane forklifts maintain consistent, 100-percent
power throughout operation. They have the ability to push and pull
heavy loads at full capacity, up and down inclines, for a longer
amount of time, and with better ground speeds than electric
forklifts.
|
|
Easy Refueling: Propane forklifts require very little
refueling time compared to natural gas-powered and electric
forklifts.
|
|
Economical: From an investment
standpoint, propane
forklifts offer an economical way to meet material handling needs.
Propane forklifts have lower life-cycle costs than electric, diesel
or gasoline-powered forklifts.
|
|
Low Maintenance: Propane produces fewer engine deposits
than gasoline and diesel fuel, resulting in lower maintenance costs.
Propane engines can typically last up to twice as long as gasoline
engines.

Propane |
�
Indoor and outdoor use
� Capable of handling rugged, unpaved, outdoor terrain, and
steep grades
� Can operate in inclement weather
|
�
Lower initial investment costs than comparable electric, CNG or
diesel forklifts
� Lower maintenance costs than diesel and electric forklifts
� Inexpensive cylinder exchange or onsite fuel storage
� Pilfer-proof; reduced loss from spillage and evaporation
|
Diesel |
�
Predominantly outdoor use only |
�
Additional cost due to pilfering, spillage losses, evaporation |
CNG |
�
Similar to propane |
�
Recertification costs: CNG cylinders must be recertified every
three years
� Establishments with CNG forklift fleet may require major
capital investment of up to $40,000 in refueling station
� If the electric service goes down, the CNG compressor
station will not work resulting in a potentially significant
production loss
� CNG compressors are expensive to overhaul
|
Electricity |
�
Typically for indoor use
� Operate only on paved or hard surfaces
� Cannot handle steep inclines
|
Higher
initial investment due to:
� Extra equipment such as batteries, charger, and battery
hoist, battery charging and wash down rooms
� Additional indoor space for recharger and battery storage
� Labor costs for changing batteries for second and third
shifts
� Ventilated storage area is required for batteries
|
Gasoline |
Typically
for outdoor use |
�
Additional cost due to pilfering, spillage losses, evaporation
� High costs to upgrade on-site fuel storage

|
6-8
hours (�- 1 shift) |
�
Requires additional training
� Maintenance intervals depend on conditions
� Must operate in a controlled environment (e.g., not in the
rain)
� Second and third shifts requires labor for battery change
|

�
Speed (max): 9.5-10.5 mph
� Lift (loaded): 83-88 fpm
|
8
hours (1 shift) |
�
Requires more frequent oil changes than propane

There are seven classes of forklifts:
|
Class 1: Electric
motor, sit-down rider, counterbalanced trucks
(both solid and pneumatic tires) |
|
Class 2: Electric
motor, narrow aisle trucks (solid tires) |
|
Class 3: Electric motor hand trucks or hand/rider trucks (solid
tires) |
|
Class 4: Internal combustion engine trucks (solid tires) |
|
Class 5: Internal combustion engine trucks
(pneumatic tires) |
|
Class 6: Electric & internal combustion engine tractors (both
solid and pneumatic tires) |
|
Class 7: Rough terrain forklift trucks
(pneumatic tires) |
Propane forklifts are primarily Class 4 and Class 5 forklifts.
