Cranes for Wood-Based Panel Production
Wood-based panel and MDF manufacturing (raw wood chips/particles at 50–200 kg/m³, hot presses at 50–300 t each, sanding machines at 5–15 t each, finished board stacks at 3–8 t per stack) is a continuous, heavy-load assembly line operation. Recommended setup: MH-type gantry crane (10–20 t) with grab, plus LD single-girder crane (5–10 t) and electric flat car. Kelude Heavy Industry's wood-based panel solution covers the full heavy-load continuous material handling chain.
The core processes in wood-based panel, MDF, and particleboard manufacturing are raw material preparation, hot pressing, sanding and thickness calibration, and finished product stacking. This is a continuous production line (running 24 hours a day), with material transferred between stations via roller conveyors and electric flat cars. This article provides a crane selection scheme for each of the four stages.
Raw Material Handling: Chip & Particle Yard and Silo Feeding
Raw materials (wood chips, particles, fibers) are stored in open yards plus enclosed silos, with yard areas typically ranging from 5,000 to 20,000 m². Material is moved by grab cranes to silo belt conveyors, then through drying drums, resin blending, and forming stations. Grab operation is high-frequency (one grab every 2–5 minutes), with each grab cycle handling 1–3 m³.
Recommended model: MH-type gantry crane, 10 t capacity with a 20–30 m span, fitted with a grab bucket (1.5–3 m³ volume, grabbing ratio 1:1.5). The grab uses either dual-rope or hydraulic open-close drive. A grizzly (200 mm spacing) is installed at the silo inlet to prevent blockages from oversized lumps. Dust collection hoods are fitted at belt conveyor transfer points.
Price reference: An MH gantry crane (10 t / 25 m span) costs approximately $15,000–$27,000 per unit, with the grab bucket at about $3,000–$6,000 per set. Kelude Heavy Industry's raw material solution includes the grab, silo grizzly, and integrated dust collection system.
Key Data: MH gantry crane grab handling in the raw material yard achieves approximately 80–120 t/h per unit, covering a yard width of 20–30 m, with a grab cycle time of about 3 minutes.
Hot Pressing: Equipment Installation for Hot Presses & Continuous Presses
Installing and maintaining hot presses (multi-layer hot presses: 50–300 t per unit; continuous presses: 100–500 t total weight) requires large-tonnage crane support. Hot platens (each weighing 1–3 t, stacked 10–30 layers) have a replacement interval of roughly 3–5 years. The hot pressing workshop operates at 40–60°C with steam and free formaldehyde present, demanding corrosion-resistant design.
Recommended model: QD Type double-girder bridge crane, 20 t capacity with an 18–24 m span, heat-resistant and anti-corrosion configuration (Class F motor insulation + epoxy coating). Hot platen replacement uses a dedicated lifting spreader with multiple lifting points to prevent platen deformation.
Price reference: QD double-girder 20 t / 20 m span: approximately $27,000–$45,000 per unit; heat-resistant and anti-corrosion options add roughly 15%. Kelude's hot pressing solution includes a dedicated hot platen lifting spreader and a formaldehyde-sealed control box.
Sanding & Thicknessing: Support for Sanding Machines & Cut-to-Size Saws
Sanding machines (5–15 t per unit) calibrate the thickness of pressed panels (thickness tolerance ≤ ±0.1 mm). Sanding rolls (200–800 kg each) require periodic replacement (every 200–500 hours of grinding once wear limits are reached). Cut-to-size saws (3–8 t per unit) divide large panels into standard specification boards. High wood dust concentrations in the workshop necessitate explosion-proof design.
Recommended model: LD Type single-girder electric overhead crane, 3–5 t capacity with a 12–18 m span, fitted with an explosion-proof electric hoist (ExdⅡBT4). Sanding roll changes are assisted by a 500 kg jib crane. The cut-to-size saw area is served by a roller conveyor line.
Price reference: LD single-girder 3 t / 15 m span: approximately $4,500–$9,000 per unit; explosion-proof configuration adds about 30%. Kelude's sanding solution includes an explosion-proof hoist and a dust-rated explosion-proof electrical cabinet.
Finished Panel Stacking: Strapping & Outbound Logistics
Finished panels (standard or large-format boards) are stacked into units (3–8 t per stack), then strapped with steel bands and edge protectors before warehousing or direct truck loading. The finished goods warehouse is expansive (5,000–15,000 m²), with stacks piled 3–5 layers high (3–5 m). Outbound loading must be fast and efficient (truck loading completed in ≤ 30 minutes).
Recommended model: Electric flat cars (10 t capacity, 30–80 m rail length) run along the loading line. Finished stacks are strapped using a semi-automatic strapping machine with a roller conveyor line. Loading is assisted by a 1 t jib crane for large panel handling.
Price reference: Electric flat car, 10 t: approximately $6,000–$12,000 per unit. Kelude's finished goods solution customizes the number of electric flat cars and strapping line configuration based on daily output.

Frequently Asked Questions
Q: How do I determine the span for a grab gantry crane in a wood-based panel raw material yard?
A: The yard span is determined by the material stacking width plus the transport aisle. Typical calculation: stacking width of 20–30 m + transport aisle of 3–4 m = span of 23–34 m. For every 2 m increase in grab gantry crane span, the main structure cost rises by approximately 8–12%. Kelude Heavy Industry calculates the optimal span based on actual yard dimensions and stacking height.
Q: What lifting spreader is recommended for hot press platens?
A: Hot press platens (each weighing 1–3 t, sized 1.3 × 2.7 m to 2 × 5.6 m) require: ① A 4-point lifting spreader beam — prevents bending deformation from the platen's own weight (flatness ≤ 0.1 mm/m); ② A hook with rotation ring — allows angular adjustment after horizontal lifting for precise positioning; ③ Lifting slings rated for temperatures above 150°C. Kelude Heavy Industry's hot press platen spreaders come with load test certificates.
Q: What are the explosion-proof requirements for wood dust in sanding workshops?
A: The lower explosion limit for wood dust in sanding workshops is approximately 40 g/m³, classifying these areas as dust explosion hazard zones (Zone 22). Explosion-proof requirements include: ① Electric hoists rated ExdⅡBT4 or Ex tD A21 IP6X (dust explosion-proof); ② Motors with IP6X protection (fully dust-tight); ③ Rail earthing resistance ≤ 4 Ω (to prevent static accumulation); ④ Control boxes located outside the hazardous area or housed in pressurized enclosures; ⑤ Daily cleaning of dust accumulation on rail surfaces (wood dust buildup exceeding 1 mm must be removed). Kelude Heavy Industry's sanding workshop solutions include Explosion Proof Certificates and integrated dust concentration monitoring.
Q: How does formaldehyde exposure in hot press workshops affect overhead cranes?
A: Hot pressing with urea-formaldehyde (UF/MUF) adhesives at 180–220°C releases free formaldehyde at concentrations of 5–20 ppm. The effects on cranes include: ① Steel structure corrosion — formaldehyde reacts with moisture on steel surfaces to form formic acid (pH ≈ 3.5), causing corrosion rates of 0.1–0.3 mm per year; ② Oxidation of electrical contact points — leading to poor connectivity. Protection measures: acid-resistant epoxy coating on steel structures + IP54-sealed motor control boxes + stainless steel fasteners. Kelude Heavy Industry's hot press workshop solutions include formaldehyde-resistant epoxy coatings and sealed control enclosures.
