Propane forklifts can be refueled by a simple cylinder change or from a bulk fuel tank. Local propane marketers often provide cylinder exchange programs that deliver filled cylinders to the work site. One full 33-lb. propane tank will last approximately 8 hours, depending on use. Propane refueling stations with state-of-the-art safety features can also be conveniently installed onsite.
Compared to other forklift refueling options, propane can be refilled safely, quickly, and easily:
- Unlike CNG forklifts, which need to be refueled after 2-4 hours of operation, or electric forklifts, which require 8-10 hours of recharging time, propane forklifts can provide consistent power around the clock with as little as five minutes' refueling time.
- The sealed fuel system of propane forklifts enhances plant safety.
- Fuel cylinders and carburetion components meet or exceed strict national code specifications.
- Propane gas operates under an average pressure of 100-200 psi compared with CNG's much higher pressure of 3,000-3,600 psi.

Refueling Procedure |
Refueling Time |
| Propane |
• Requires moderately pressurized storage tanks which can be located outdoors
• Easy to service
• Propane is non toxic and does not contaminate water or soil
|
• Simple, safe, non-toxic liquid transfer
• Immediate operation
|
Less than 5 minutes
|
| Diesel |
• Toxic fuel - EPA storage regulations apply (40CFR280)
|
• Potential for toxic hazardous spillage during refueling
|
Less than 5 minutes
|
| CNG |
• Requires tanks at extremely high pressure (3,000 - 3,600 psi)
• EPA regulations do not apply to storage
• Tanks require recertification
|
• Time consuming, costly refueling procedure

|
Fast fill: 4-7 minutes
Slow fill: 8 hours
|
| Electricity |
• Battery and caustic acid storage

• Time consuming, costly recharging procedure (labor costs for changing batteries)
• Limited battery life
|
8-10 hours
|
| Gasoline |
• Complex storage
• Toxic fuel - EPA storage regulations apply (40CFR280)
|
• Potential for toxic hazardous spillage during refueling, low flash point
|
Less than 5 minutes
