Crane Solutions for LED Manufacturing: Chip, Packaging & Module
LED lighting manufacturing (chip epitaxy <5kg, die bonders 200–500kg, module assembly, luminaire final assembly 50–200kg) is light-load precision electronics manufacturing. Recommended setup: KBK 250kg with pneumatic balancer + LD single-girder electric crane 1–3t + AGV logistics. All Kelude LED solutions feature ESD-safe design throughout.
LED lighting manufacturing spans four key stages: chip epitaxy, die bonding, module SMT, and luminaire final assembly. The front end is high-cleanliness precision semiconductor processing, while the back end is light-load electronic product assembly. This article provides differentiated crane solutions tailored to each of the four process environments.
MOCVD Equipment Handling in Cleanrooms — Heavy Equipment Installation
LED chip epitaxy relies on MOCVD equipment (2–5t per unit) installed in Class 1,000/10,000 cleanrooms. The precision optical components are vibration-sensitive (allowable vibration ≤0.5μm/s). Installation must be completed inside the cleanroom, covering the full transfer path from the unloading dock to the cleanroom installation position.
Recommended model: LD single-girder electric overhead crane, 3–5t / span 8–12m, covering the cleanroom equipment handling zone. The crane features Stainless Steel construction, dust-free lubrication (food-grade white oil), and sealed motors (IP54 + sealing cover). Equipment installation is supported by an air-cushion transfer system (5t load capacity, film-type air casters reducing floor friction).
Price Reference: LD single-girder crane, 3t/10m span: approx. $3,000–$7,500 per unit. Stainless Steel and dust-free configurations add roughly 30%. Kelude's LED chip handling solution includes air-cushion transfer carts and a three-stage cleanroom buffer vestibule design.
Packaging & Die Bonding Equipment Handling – Precision Positioning
Die bonders (200–500 kg per unit) and wire bonders (300–600 kg per unit) in the packaging workshop are high-precision machines requiring installation levelness of ≤0.05 mm/m. Equipped with vibration-damping feet, these machines must be moved with acceleration kept below 2g. The workshop maintains a cleanliness rating of ISO Class 7.
Recommended Model: KBK flexible modular crane, 500 kg capacity, covering the equipment installation area and paired with an intelligent lifting device (iLift) for zero-gravity handling. An AGV (1t load capacity, ±10 mm navigation accuracy) manages in-workshop equipment transport.
Price Reference: KBK 500 kg system: approx. $3,000–$6,000 per set; iLift: approx. $1,500–$3,000 per unit. Kelude's packaging solution includes a Stainless Steel lifting spreader and anti-static (ESD) protective wrapping.
SMT Assembly Line – Placement Machine & Reflow Oven Installation
SMT placement machines (1–2t per unit) and reflow ovens (2–3t per unit) require equipment relocation and level calibration (accuracy ≤0.1 mm/m) during installation. SMT facilities are typically multi-story buildings (floor load capacity: 500–750 kg/m²), so heavy equipment must be positioned on the ground floor or in structurally reinforced zones.
Recommended Model: LD single-girder electric overhead crane, 3t capacity, 8–12m span, covering the SMT equipment entry area. Placement machines are moved using a dedicated transfer cart fitted with precision adjustment bolts, while the crane handles unloading from delivery trucks onto the cart.
Price Reference: LD single-girder crane, 3t/10m span: approx. $3,000–$7,500 per unit. Kelude's SMT solution includes a vibration-damping transfer cart and spirit level calibration service.
Final Assembly Line – Product Assembly & Packaging Logistics
On the LED luminaire (downlight/panel light/street light) final assembly line, individual finished products weigh 5–50 kg, with packing cases ranging from 50–200 kg. The line operates on station-based assembly with mass production throughput of 1,000–5,000 units per day. Finished goods are palletized for warehouse storage (pallet weight: 300–500 kg).
Recommended Model: KBK suspension rail system, 250 kg capacity, covering packing case offloading along the final assembly line. AGVs or electric flat cars (1–2t capacity) transport finished pallets to the automated warehouse. A telescoping belt conveyor at the outbound dock loads trucks directly.
Price Reference: KBK 250 kg system: approx. $2,200–$4,500 per set; AGV: approx. $7,500–$12,000 per unit. Kelude's lighting solution integrates KBK and AGV systems to cut manual handling by 80%.

FAQ
Q: What is the handling process for MOCVD equipment from unloading to the cleanroom?
A: The process is as follows: ① The truck arrives at the unloading dock — an overhead LD crane in the workshop lifts the equipment onto an air-cushion transfer platform; ② The platform passes through a buffer zone into the cleanroom (three-stage buffering, with a pressure differential of ≥5Pa at each stage); ③ Inside the cleanroom, the air-cushion handling system moves the equipment to its installation position; ④ After the leveling feet are locked, grouting is applied for fixing. The entire process takes 4–6 hours. Kelude Heavy Industry offers air-cushion handling system rental services.
Q: How is the levelness of die bonder installation ensured?
A: The die bonder (weighing 200–500 kg) requires an installation levelness of ≤0.05mm/m. The method: ① Place precision spirit levels (accuracy 0.02mm/m) at the four corners of the equipment base; ② Adjust the height of the vibration-damping leveling feet until the spirit level readings are ≤0.05mm/m; ③ Perform diagonal cross-checks (difference between points A and B ≤0.03mm); ④ Re-verify with a laser level. Kelude Heavy Industry provides precision spirit level rental and calibration services.
Q: How should heavy SMT equipment be handled when the workshop is on an upper floor?
A: When the SMT workshop is on an upper floor (floor load capacity 500 kg/m²) and the SMT placement machine/reflow oven weighs over 2 t: ① Preferred — place equipment on the ground floor and use a lift (3 t load capacity) to transport PCBs and materials to the production line upstairs; ② Alternative — reinforce the floor structure at the equipment location (support with H-Beam columns extending from the ground floor); ③ Not recommended — installing heavy equipment directly on a standard floor slab. Kelude offers equipment layout and structural reinforcement solutions.
Q: What navigation method is recommended for AGVs on an LED luminaire final assembly line?
A: Recommended AGV navigation for luminaire final assembly lines: ① Magnetic tape navigation — low cost (approx. $3,000 per unit), ideal for fixed routes, accuracy ±10 mm; ② Laser SLAM — flexible (approx. $12,000 per unit), suited for factories with frequent line adjustments, accuracy ±20 mm; ③ QR code navigation — high accuracy (±5 mm), ideal for high-density warehousing. For an annual output of 1 million luminaires, magnetic tape navigation is recommended (best cost-performance ratio). Kelude provides AGV selection and route planning services.
