Forestry loader cranes (also called timber loader cranes or log loader cranes) are heavy-duty hydraulic cranes designed for fast, repetitive timber handling. Compared with general-purpose truck cranes, forestry models are typically configured with a log grapple + rotator, reinforced boom structure, and work-ready hydraulics for high-cycle loading in forests, log yards, and sawmills.
Below is a complete buyer-oriented guide based on your outline, covering pricing factors, specs, chassis choices, customization, and how to select a reliable China supplier.
A forestry loader crane is used to pick, rotate, sort, and load logs efficiently. Common mounting formats include:
Truck-mounted forestry loader crane: crane + timber body on a road-going truck (transport and loading in one unit).
Trailer-mounted forestry loader crane: crane on a forestry trailer (often paired with a tractor for off-road operations).
Fixed/yard-mounted loader crane: installed at log yards, sawmills, or biomass stations.
Typical working components:
Crane (knuckle boom or straight boom)
Grapple (log grapple or sorting grapple)
Rotator (often continuous 360°)
Hydraulic system (PTO-driven pump on trucks or separate hydraulic power pack)
Stabilizers/outriggers + subframe (critical for stability and chassis protection)
What buyers usually prioritize when sourcing from China:
Correct lifting capacity at required outreach (via load chart, not just “tonnage”)
Suitable grapple/rotator package for log size and workload
Stable mounting and compliant axle loads (for truck builds)
Quality control, spare parts availability, and after-sales support
Forestry loader crane pricing varies widely because configurations vary. Instead of comparing only the total price, compare the full configuration scope and the load chart.
Key price drivers:
Capacity class + outreach (longer reach and higher capacity require heavier structure)
Boom type (knuckle boom is commonly preferred for forestry; straight boom can be simpler)
Hydraulic performance (pump flow, valve type, oil cooler, filtration, continuous rotation)
Attachments (grapple size/type, rotator torque rating, extra hydraulic lines)
Control options (manual levers vs electro-hydraulic joysticks vs radio remote control)
Mounting package (subframe design, outriggers, PTO, hydraulic tank, hose routing)
Complete unit vs crane-only (a full truck with timber body, lighting, and compliance items costs more)
Export requirements (inspection, documentation, packing standard, destination compliance needs)
Tip for accurate comparison: ask suppliers to quote in the same structure:
Crane model + load chart
Grapple + rotator specs/brands
Mounting kit scope
Chassis brand/model (if included)
Warranty terms and spare parts list
Forestry loader cranes are commonly used for:
Logging operations: loading felled logs onto trucks/trailers at harvesting sites
Timber yard handling: stacking, sorting by grade/length, feeding processing lines
Sawmill and biomass facilities: continuous unloading and pile management
Forest road work: handling culverts, mats, barriers, and heavy materials (when properly configured)
Land clearing and cleanup: moving storm-damaged timber and debris (attachment-dependent)
Choosing the right crane setup depends heavily on your typical log diameter/length, loading radius, terrain, and daily cycle rate.
For forestry work, the most important specification is the load chart (capacity at each working radius), not the single “maximum lifting capacity” headline.
Key terms to confirm:
Max lifting moment (often used to classify cranes)
Max outreach (horizontal reach from crane center)
Rated capacity at specific radius (e.g., at 3 m, 6 m, 8 m)
Slewing range and rating conditions (front/side/rear, outriggers extended or not)
Buyer checklist (practical):
What is your real working radius during loading? (common error: buying based on short-radius ratings)
Will the crane lift over the rear or side mostly?
Are outriggers fully deployed on your sites?
Is the load mostly logs (dynamic swinging) or stable pallets? Logs often require extra safety margin.
Knuckle boom (articulated)
Pros: excellent positioning, fast sorting/stacking, works well in tight spaces and uneven piles
Cons: more joints/components; needs good maintenance and sealing quality
Straight boom (telescopic or fixed)
Pros: simpler structure, often straightforward for direct loading tasks
Cons: less flexible for close-in maneuvering and repetitive pile sorting
In many timber-loading scenarios, knuckle boom + rotator + grapple is the standard productivity setup.
Attachments determine real efficiency. Common options include:
Grapples
Log grapple: general log loading, round timber
Sorting grapple: better control for mixed piles, branches, uneven bundles
Biomass/brush grapple: for lighter, bulkier material
Key grapple parameters:
Opening width (max/min)
Grapple area/volume
Jaw shape and tooth design
Pin/bushing wear design and grease points
Working pressure/flow compatibility
Rotators
Continuous 360° hydraulic rotator (common for forestry)
Key specs: torque, speed, load rating, hose protection, seal quality
Ask the supplier to confirm compatibility between crane flow/pressure and the grapple/rotator package to avoid slow cycle times or overheating.
A forestry loader crane is a high-cycle hydraulic machine. Stable, cool-running hydraulics matter as much as raw lifting ratings.
Hydraulic options to consider:
Pump flow (higher flow = faster work cycles)
Working pressure (affects lifting and gripping force)
Valve type (proportional control improves smoothness and precision)
Oil cooler (recommended for hot climates and intensive yard work)
Filtration level (extends valve/cylinder life)
Hose routing/guards (prevents branch and abrasion damage)
Control options:
Manual lever controls (cost-effective, simple)
Joystick controls (better ergonomics)
Electro-hydraulic proportional control (smooth and efficient)
Radio remote control (improves visibility and safe positioning during loading)
Swing/rotation:
Check slewing torque, speed, and whether the crane can rotate smoothly under load.
Confirm limits and safety interlocks where required.
Stability and mounting quality are decisive for safe lifting and long service life.
Stabilizers/outriggers
H-type outriggers are common for truck-mounted loader cranes
Important specs: outrigger span, cylinder capacity, pad size, and structural reinforcement
For soft ground, larger pads and ground plates reduce sinking risk
Subframe
Transfers crane loads into the vehicle correctly
Reduces chassis twisting and fatigue cracking
Should be engineered for your chassis wheelbase, axle loads, and operating conditions
Mounting types
Truck-mounted: best for combined transport + loading
Trailer-mounted: often better for off-road forestry extraction and maneuverability
Request mounting drawings and, for truck builds, ask for axle load distribution estimates after installation.
If you’re buying a complete forestry crane truck from China, match the chassis to terrain and legal limits.
Common drive configurations:
4×2: lighter work, more road-focused
6×4: common for forestry transport, good traction and payload balance
8×4: higher payload potential in some markets (check local regulations)
Engine and drivetrain considerations:
Emission standard requirements for your destination
PTO compatibility for hydraulic pump drive
Gearbox and torque curve suited to off-road starts and heavy loads
Cooling capacity (important for slow-speed off-road driving)
Also confirm:
Wheelbase suitability for crane position + timber body length
Tire specification for mixed on-road/off-road use
Availability of service parts in your region (filters, belts, sensors)
Recommended safety and protection features for forestry operation:
Overload protection / load moment limiting (where applicable)
Hydraulic holding valves to reduce risk of sudden drop
Emergency stop
Anti-slip steps and platforms
Guards for hoses and cylinders (branches and debris protection)
Outrigger interlocks / status indication
Work lights and warning alarms (especially for road-going trucks)
Always align the final configuration with your local safety rules, operator training requirements, and site procedures.
Common custom options from China suppliers include:
Custom boom length/outreach packages
Heavy-duty forestry hose protection kits
Additional auxiliary hydraulic circuits (for different attachments)
Enhanced oil cooling for high-cycle yard operations
Toolboxes, chain racks, spare hose storage
Timber body options: stakes, bunks, twist locks, rear protection, tie-down points
Paint system upgrades (anti-corrosion), custom color and branding
For custom builds, confirm drawings and final dimensions before production (especially vehicle overall length/height and transport compliance).
“Best” depends on your target market, duty cycle, and service expectations. When evaluating manufacturers/factories, focus on measurable capabilities:
Forestry export experience (similar cranes delivered to your region)
Ability to provide load charts, drawings, and hydraulic schematics
Consistency of key components (cylinders, valves, slewing bearing, rotator/grapple)
Welding and structural fabrication capability for heavy-duty booms
Spare parts supply and lead time
If you need, you can shortlist suppliers by requesting the same data package from each and comparing it side-by-side.
Reliable suppliers typically offer:
Pre-sales selection support (capacity/outreach matching, stability and mounting guidance)
GA drawings and subframe design confirmation
Installation guidance (especially for crane-only purchases)
Commissioning checklist and operator manual
Remote troubleshooting via video call and hydraulic/electrical diagrams
Spare parts recommendation list for first-year operation
Ask in advance:
Response time SLA (e.g., 24–48 hours for technical replies)
Warranty coverage details (structure vs hydraulics vs wear parts)
How parts are shipped and typical dispatch time
Typical QC steps you can request evidence for:
Incoming inspection for steel and hydraulic components
Weld inspection and dimensional checks
Hydraulic pressure testing and leak inspection
Functional testing (boom, swing, outrigger, grapple/rotator operation)
Paint preparation and coating thickness checks
Final inspection report with serial number tracking
Certificates vary by factory and destination market. Common requests include:
ISO-quality management certification (if available)
Material certificates for key structural parts (if required)
Factory test reports
Support for third-party inspection (SGS/BV/TÜV or your appointed inspector)
A practical selection method:
Start with your working conditions: log size, working radius, terrain, daily cycle
Demand the load chart for the exact model/outreach
Confirm the full package scope (crane + grapple + rotator + hydraulics + mounting)
Review drawings: subframe, outrigger layout, hose routing, overall dimensions
Check component transparency: brands/models of pump/valves/rotator if specified
Ask for inspection support and previous export references
Evaluate after-sales plan: parts list, troubleshooting process, warranty clarity
Common red flags:
No load chart or vague “X tons” without radius
Unclear configuration list (missing rotator torque/spec, missing hydraulic cooling details)
“Universal fit” mounting claims without subframe engineering confirmation
Lead time depends on whether you buy crane-only or a complete truck, plus customization depth. A typical process:
Requirement confirmation → drawings approval → production → factory testing → packing → shipment
Shipping methods:
Ro-Ro: often used for complete trucks (route dependent)
Flat rack / breakbulk: common for oversized units
Container: common for crane-only or smaller assemblies
Before shipment, confirm:
Packing method (anti-rust treatment, seaworthy protection)
Included documents (packing list, invoice, manuals, certificates if applicable)
Spare parts package and tools
Warranty start point (shipment date vs arrival vs commissioning—must be written clearly)
After-sales channels and escalation process
To get a correct crane selection and avoid mismatched capacity, provide:
Logs: max diameter, typical length, max bundle weight
Required working radius (meters) and loading direction (side/rear)
Preferred boom type: knuckle or straight
Mounting: truck or trailer (and target chassis: 4×2 / 6×4 / 8×4)
Controls: manual / joystick / remote
Attachment needs: grapple type + continuous rotator required?
Environment: temperature range, high dust, high-duty cycle hours/day
