8 Components for Building a DIY Firewood Conveyor

Splitting ten cords of hardwood before winter is satisfying work, but manually tossing heavy green logs into high-sided trailers or elevated storage bins destroys backs and burns daylight. Building a custom firewood conveyor solves this bottleneck by letting hydraulic power do the heavy lifting from the splitter wedge straight to the pile. With a carefully chosen set of robust structural, mechanical, and hydraulic components, any small-acreage homestead can assemble a reliable, long-lasting elevator tailored to its exact property layout.

Key Planning Factors Before You Build a Conveyor

A practical firewood conveyor must balance overall reach with structural stability. A 16-to-24-foot conveyor usually hits the sweet spot for loading pickup beds, dump trailers, and elevated wood shed bays without tipping. Going longer creates excessive tongue weight and requires heavy bracing, while building shorter severely limits your stacking height.

Power source integration demands early decisions. You can tap into an existing log splitter’s hydraulic circuit using a power-beyond port, or mount a dedicated small gas engine with an independent pump. Matching fluid flow rates in gallons per minute (GPM) and working pressure ratings ensures smooth operation without overheating hydraulic fluid during long processing afternoons.

Mobility around an uneven barnyard requires a well-balanced undercarriage. Placing the axle slightly behind the center of gravity keeps positive tongue weight on your utility tractor or ATV hitch during transport. Keep structural weight manageable so moving the machine across soft ground does not turn into an afternoon struggle.

Hydraulic Motor – Eaton Char-Lynn 2000 Series

A conveyor motor must convert hydraulic fluid flow into steady, low-speed, high-torque rotary power to pull heavy, wet oak rounds up an incline without stalling. Electric motors struggle with outdoor moisture and cord limits, while standard high-speed hydraulic motors lack the low-end muscle needed to start a fully loaded belt.

The Eaton Char-Lynn 2000 Series geroler motor is an industry standard for agricultural drives because of its incredible low-speed displacement and smooth starting torque. Its heavy-duty disc valve design withstands continuous back-pressure and large thermal swings during all-day processing sessions in cold weather.

• Displacement options: 6.2 to 29.8 cu in/rev to match common tractor or log splitter hydraulic pumps
• Operating pressure: Rated up to 3,000 PSI continuous for high starting loads
• Output shaft: 1-1/4 inch keyed steel shaft that easily resists heavy radial side-loads from drive chains

This motor is the right choice for fabricators plumbing directly into an 8 to 15 GPM hydraulic system who need reliable 30 to 60 RPM belt drive speeds. It is oversized for micro-scale conveyors running on small 12-volt battery setups.

Control Valve – Prince RD5000 Hydraulic Valve

The directional control valve serves as the primary operator interface, regulating fluid flow to start, stop, and reverse the conveyor belt. Firewood occasionally wedges against the trough sides, making an instantaneous reverse function vital for clearing jams safely without shutting down the entire splitter rig.

The Prince RD5000 Series valve provides exceptional flow modulation inside a rugged, heavy cast-iron monoblock body designed for exposed agricultural environments. Its built-in adjustable relief valve protects your hydraulic motor and mechanical drive components from catastrophic overpressure if a log wedges hard in the conveyor frame.

• Flow capacity: Rated for up to 30 GPM to prevent fluid restriction and heat buildup
• Port sizing: Standard 3/4-inch NPT or SAE inlet and outlet ports for easy hose plumbing
• Spool configuration: 4-way, 3-position with a spring-center or friction detent option for hands-free continuous belt feeding

This valve fits builders creating an integrated two-machine setup where independent belt speed control and quick jam-clearing are essential. It is unnecessary if you power the conveyor via an electric motor controlled by an electronic switch.

Conveyor Belting – Apache Chevron Cleated Belt

The belt must haul wet, sap-covered, irregularly shaped logs up steep angles without allowing chunks to slide backward into the loading zone. Smooth belts fail the moment wood gets wet or icy, causing dangerous rollbacks and bottlenecking the splitter.

The Apache Chevron Cleated Belt solves rollback problems with continuous vulcanized V-shaped cleats molded directly into the rubber top cover. The aggressive chevron pattern cups split logs securely, allowing steep conveyor elevation angles without losing traction on smooth hardwood bark.

• Cleat profile: 1/2-inch to 1-inch raised molded chevrons for aggressive grip
• Carcass build: Multi-ply polyester-nylon fabric carcass that resists stretching and impact punctures
• Cover compound: Heavy-duty, abrasion-resistant rubber formulated to withstand weather, sun, and wood sap

This belting is essential for steep-incline conveyors loading high wood ricks or tall dump trailers in rain and snow. It is not designed for flat horizontal sorting tables where non-cleated PVC belts are adequate.

Drive Pulley – PPI Heavy Duty Crowned Drum Pulley

The head pulley mounts at the top discharge end, gripping the conveyor belt to pull the load upward while maintaining proper belt tracking under off-center loading. Firewood rarely lands dead-center on the belt, which creates uneven forces that cause flat pulleys to throw the belt off track.

The PPI Heavy Duty Crowned Drum Pulley features a precision-machined crown taper that naturally guides the belt toward the center of the conveyor frame. Adding vulcanized rubber lagging provides the friction needed to drive heavily loaded belts without slipping, even when sawdust and bark coat the underside of the belting.

• Crowned profile: Slight center taper provides continuous, self-centering belt tracking
• Hub style: Heavy-duty XT or QD bushed hubs for secure, non-slip locking on drive shafts
• Diameter sizing: 8-inch to 10-inch outer diameter prevents excessive bending fatigue on multi-ply rubber belts

This component is tailor-made for the top drive head of an outdoor elevator where dependable, slip-free pulling power is critical. It is overkill for lightweight canvas belts or flat grocery-style conveyors.

Idler Pulley – Dodge Heavy Duty Wing Tail Pulley

The tail pulley sits at the bottom infeed end, providing belt tension and redirecting the belt back up toward the discharge head. Because logs drop directly onto the belt above this area, bark, wood chips, and gravel constantly fall onto the pulley face.

The Dodge Heavy Duty Wing Tail Pulley utilizes open steel wings with spiral gussets that actively cast falling debris away from the belt. As the pulley turns, loose bark drops through the open vanes instead of being crushed between the belt and pulley face, preventing belt gouging and mistracking.

• Self-cleaning design: Open radial wings expel wood debris outward away from the pinch zone
• Bushing mount: Taper-Lock or HE bushed hubs allow easy alignment adjustments on threaded tensioners
• Structural strength: Heavy-gauge steel crossbars withstand direct impact from dropped logs

This tail pulley is indispensable at the infeed hopper directly beneath a log splitter discharge chute. Do not use a wing pulley at the top drive position, as it lacks sufficient surface contact to pull a loaded belt.

Pillow Block Bearings – Timken UC200 Series Unit

Pillow block bearings secure the drive and idler shafts to the main structural frame, carrying substantial mechanical loads while allowing smooth shaft rotation. Firewood equipment lives outdoors in dust, rain, and mud, where cheap bearings seize quickly and ruin drive shafts.

The Timken UC200 Series wide-inner-ring ball bearing units feature rigid cast-iron housings that handle severe radial loads without cracking. Their heavy-duty contact seals lock clean grease inside while blocking wood fibers, pulverized bark, and abrasive grit from reaching the precision ball tracks.

• Housing construction: High-strength cast iron with rigid dual-bolt base mounting slots
• Shaft attachment: Dual set-screw locking collar provides positive hold on standard turned shafts
• Serviceability: Integrated grease zerk fitting allows seasonal purging of old grease and contaminants

These units are the premier choice for mounting 1-inch to 1-1/2-inch drive and tail shafts to structural channel frames. They are not intended for unlubricated, throwaway builds or high-speed industrial machinery running continuous multi-shift operations.

Frame Channel – Metal Supermarkets C3 Steel Beam

The frame serves as the structural backbone of the conveyor, supporting the belt, drive components, undercarriage, and the dead weight of multiple green logs. Cyclic shock loading from dropped splits will quickly twist thin sheet metal or lightweight square tubing.

Standard structural C3 Steel Channel (3-inch structural steel) provides high beam strength with straightforward weldability and manageable total weight. The flat web and tapered flanges offer excellent mounting planes for pillow block bearings, cross-members, slide trays, and protective side flares.

• Dimensions: 3-inch web height with thick structural flanges for superior torsional rigidity
• Material standard: ASTM A36 hot-rolled steel offering easy cutting, drilling, and MIG or stick welding
• Deflection resistance: Maintains straight alignment over 16-to-20-foot spans when paired with basic truss bracing

This structural steel channel is designed for fabricators building a rigid, durable conveyor truss using standard home-shop welding equipment. It is too heavy for small, hand-portable garden elevators, which require extruded aluminum rails.

Brake Winch – Dutton-Lainson Heavy Duty Hand Winch

An adjustable conveyor requires a dependable lift mechanism to raise and lower the discharge height for different truck beds and wood shed doorways. Using a standard boat trailer ratchet winch is dangerous because releasing the ratchet pawl under load can cause the crank handle to spin violently out of control.

The Dutton-Lainson Heavy Duty Brake Winch (B-Series) uses an internal automatic friction brake that locks the boom instantly whenever the operator lets go of the handle. This allows precise, controlled adjustments up or down without the risk of the conveyor crashing to the ground.

• Lifting rating: 1,200 to 2,500 lbs capacity options to handle fully rigged conveyor booms
• Braking mechanism: Automatic self-activating mechanical friction brake holds loads continuously
• Corrosion resistance: Heavy-gauge TUFFPLATE or zinc finish withstands year-round outdoor storage

This winch is a critical safety item for any adjustable A-frame conveyor undercarriage. It is not suitable for motorized hoisting applications or horizontal pull-only vehicle recovery.

Essential Safety Rules for Firewood Conveyors

Conveyors present severe mechanical pinch points, particularly at the bottom infeed where the belt meets the tail pulley. Always fabricate solid steel or expanded metal guards around the lower wing pulley and encase all drive chains, sprockets, and motor couplings in sturdy metal enclosures.

Position your hydraulic control lever within arm’s reach of the log splitter operator so the belt can be halted instantly if an issue arises. Ensure the hydraulic circuit includes an operational pressure relief valve set to stall the motor safely before excessive pressure snaps the drive chain or tears the belt during a jam.

Always operate the conveyor on firm, level ground with wheel chocks firmly planted in front of and behind the tires. Before winching the boom upward, visually check the overhead area for utility lines, tree branches, and building eaves to avoid dangerous electrical or structural contact.

Setting the Ideal Angle and Conveyor Belt Speed

The most efficient incline angle for a cleated firewood conveyor sits between 25 and 32 degrees. Setting the boom steeper than 35 degrees causes round, unsplit logs to roll backward over the cleats, creating an impact hazard for anyone working near the loading trough.

Aim for a belt speed of roughly 60 to 90 feet per minute (FPM). Operating faster throws wood erratically off the top pulley, scattering the wood pile and stressing bearings, while running too slowly causes logs to back up and jam in the splitter chute.

Use the flow control on your hydraulic valve to dial in the speed until it matches your natural splitting rhythm. A balanced pace keeps the infeed clear, gives the operator time to inspect logs, and allows small debris to drop freely out of the wing pulley.

Routine Conveyor Maintenance for Year-Round Use

Grease all pillow block bearings every 25 to 50 hours of operation using a high-tack lithium complex grease to purge out water, sap, and dust. Inspect belt tension weekly by checking for sag on the return run; the belt must remain taut enough to prevent drive drum slippage without over-stretching the internal carcass.

Examine all hydraulic hoses, fittings, and quick-disconnect couplers for abrasion and leaks before starting seasonal wood processing. Replace return-line filters annually on your power unit to prevent dirt and wood dust from contaminating the hydraulic reservoir and scoring the motor gears.

When parking the conveyor for the off-season, lower the boom completely to relieve structural stress on the lift cable, pulleys, and winch. Coat bare steel channel, pivot pins, and drive sprockets with a heavy corrosion-inhibiting oil to prevent rust buildup during wet winter months.

Building your own firewood conveyor turns one of the most punishing farm chores into a smooth, one-person processing line. By assembling quality structural steel, purpose-built agricultural pulleys, and reliable hydraulic components, you create a workhorse that serves your homestead for decades. Source the right parts, take your time with frame alignment, and enjoy effortless wood handling every burning season.
