How to Ship a Knuckleboom Loader or Grapple Truck: Complete Transport Guide

Types of Knuckleboom Loaders and Grapple Trucks

Knuckleboom loaders and grapple trucks come in several configurations with different transport requirements:

• Truck-Mounted Grapple Loaders: These are knuckleboom cranes mounted directly to a truck chassis (typically a Class 8 semi or heavy-duty straight truck). The truck and loader are transported together as a single unit. GVW typically ranges from 54,000–80,000 lbs depending on the chassis and loader configuration.
• Standalone Forestry Knuckleboom Loaders: These are self-propelled or trailer-mounted units used in logging operations. They fold into a transport configuration with typical dimensions of approximately 8.5 feet wide, 13–14 feet tall, and 50–55 feet long. Operating weight ranges from 40,000–80,000 lbs depending on the model.
• Scrap and Waste Grapple Trucks: Similar to forestry units but configured for scrap metal or waste handling. These are typically truck-mounted and transport as a complete unit.

Trailer Selection

The right trailer depends on the machine's configuration and dimensions:

• Flatbed Trailer: Suitable for truck-mounted grapple units that fit within legal dimensions when the boom is folded. The truck drives onto the trailer or is loaded with a ramp.
• Step-Deck (Drop-Deck) Trailer: Used for standalone forestry loaders that need a lower deck height to stay within legal height limits. Most forestry knuckleboom loaders in transport configuration (13–14 feet tall) require a step-deck to stay under the 13.5-foot legal height limit.
• RGN (Removable Gooseneck) Trailer: Required for heavier standalone loaders that exceed step-deck weight capacity, or for machines that cannot be driven onto a raised trailer.
• Lowboy: Used for the heaviest standalone loaders where weight distribution across multiple axles is required.

Permit Requirements

Truck-mounted grapple units often ship without permits if the truck and loader combination fits within legal dimensions. However, standalone forestry loaders frequently exceed the 8.5-foot width threshold or the 13.5-foot height threshold, triggering oversize permit requirements in every state traversed. Any load exceeding 80,000 lbs gross vehicle weight also requires an overweight permit. Permits must be obtained separately for each state and typically process in 2–5 business days.

Pre-Transport Preparation

Before loading, take the following steps:

• Fold the boom and grapple into the transport position and verify all locks are engaged.
• Measure the machine in transport configuration — length, width, and height — to confirm trailer selection and permit requirements. Do not rely on manufacturer specs alone; aftermarket attachments and modifications can change dimensions.
• Check for fluid leaks in hydraulic lines, cylinders, and the grapple mechanism. Address any active leaks before loading.
• Drain fuel to approximately 1/4 tank to reduce weight and fire risk.
• Photograph the machine from all angles before loading to document pre-existing condition.

Site Access Considerations

Knuckleboom loaders and grapple trucks are often located at logging yards, scrap facilities, and waste transfer stations — locations that may have limited access for transport vehicles. Before scheduling pickup, confirm that the site can accommodate a step-deck or RGN trailer with approximately 75–80 feet of straight approach. Soft ground, narrow gates, and low overhead obstacles can prevent loading. IronHaul's dispatch team will ask about site access conditions when booking your shipment.
