The idea of using one forklift to lift, hold, or move another might seem like a practical solution in a pinch. However, from a safety, regulatory, and practical standpoint, this practice is extremely dangerous and almost always prohibited. Lifting a forklift with another forklift is not only unsafe but can also be a direct violation of OSHA standards.
The Core Problem: Why It's So Dangerous
There are several critical reasons why forklift-on-forklift lifting is considered a high-risk activity.
Disrupted Balance and Tipping
Forklifts are designed with a precise counterweight system to balance specific loads. Lifting another forklift, which is itself a complex, heavy machine, will unpredictably disrupt this balance, significantly increasing the risk of tipping. The dynamic nature of the load means its weight can shift during the lift, potentially causing a sudden and catastrophic loss of stability.
Structural Damage
The act of lifting another forklift can place extreme and uneven stress on the lifting forks, mast, and carriage of both machines. This can lead to structural damage that may render them unsafe for future operations. The lifting chains and the heels of the forks are particularly vulnerable points.
Unpredictable Weight Distribution
A forklift is not designed to be a lifted load. Its center of gravity and weight distribution are not uniform, making it a highly unpredictable object to lift. This unpredictability makes it nearly impossible to ensure a safe and stable lift.
The Regulatory Perspective: What OSHA Says
OSHA regulations are clear on this matter. A forklift is only rated to handle loads within its specified capacity. Lifting another forklift is generally considered a use inconsistent with the machine's design and purpose.
Furthermore, OSHA does not permit the use of two forklifts to split a load that exceeds the capacity of a single truck. The "load" is defined as the total weight of the object, not a portion of it. Using two forklifts to lift a single, overweight object would violate OSHA's rules.
Key Violations:
Using a forklift in a manner inconsistent with its design
Exceeding the forklift's rated capacity
Operating without proper safety protocols for suspended loads
Failing to provide a workplace free from recognized hazards
Potential Penalties: OSHA violations can lead to significant fines and legal liability. In the event of an accident, the employer would be held responsible for the unsafe work practice.
The One Exception: Towing a Disabled Forklift
The only scenario where using one forklift to move another is acceptable is towing a disabled forklift. However, this is an emergency procedure and must be performed following strict guidelines. This is not a lift but a low-speed, short-distance move on a level surface.
Safe Towing Practices:
Use the Tow Point: The towing forklift must connect to the disabled forklift's designated tow pin or coupling. Never attach a tow chain to the mast or other parts.
Equal or Larger Size: The towing forklift must be at least as large and heavy as the disabled unit to ensure it has enough weight and braking power.
Low Speed: Towing must be done at a very slow speed, typically no faster than 2 km/h (1.2 mph).
Secure the Disabled Forklift: Ensure the disabled forklift's parking brake is released, the key is off, and the transmission is in neutral.
Angle Limit: Keep the tow bar angle to a minimum, not exceeding 30 degrees from straight ahead.
Safe Alternatives for Moving Forklifts
If you need to move a forklift, there are safe and approved methods to use.
1. Professional Transport
For long-distance moves or relocations, the safest method is to use a professional heavy equipment transport company. They have the specialized trailers, equipment, and expertise to load, secure, and transport forklifts safely.
2. Specialized Lifting Equipment
Instead of using one forklift, use equipment designed for the task. A telehandler with a heavy-duty lifting frame, a crane, or a mobile gantry system can lift and move a forklift safely without the inherent risks.
3. Attachments for On-Site Movement
For moving a forklift a short distance within a facility, consider using a specialized attachment like a heavy-duty lifting frame or a jib boom designed for machinery transport. These attachments provide a more secure and stable lift than using standard forks.
The Bottom Line
Using one forklift to lift or hold another forklift is an extremely dangerous practice that violates safety regulations and poses a significant risk of tipping, structural damage, and serious injury. The only acceptable method for moving a forklift with another forklift is towing a disabled unit at very low speed, using the designated tow points and following strict safety protocols. For any other situation, always use specialized equipment or professional transport services to move forklifts safely and legally.
