Crane Solutions for Musical Instrument Manufacturing
Musical instrument manufacturing involves vastly different processes—piano cast-iron plates (200–500 kg each), violin maple stock (under 10 kg), brass sheet for wind instruments (200–500 kg per coil), and light-load SMT handling for electronic instruments. We recommend an LD single-girder crane (3–5 t) with a tilting spreader for pianos, a KBK 500 kg workstation with a pneumatic balancer, and an explosion-proof jib crane. Kelude's industry solutions for musical instruments are tailored to each product category.
Piano Assembly Crane Systems — Cast Iron Plate & Wooden Cabinet Handling
The core components of piano manufacturing include the cast iron plate (200–500 kg, requiring a 90° flip after sand casting for underside inspection), the wooden cabinet (solid wood/MDF, 80–200 kg after assembly), and the action mechanism (precision machinery, 30–50 kg). The cast iron plate must be rotated 90° for inspection, while cabinet assembly demands scratch protection. A fully assembled piano weighs between 200 and 500 kg.
Recommended Model: LD single-girder electric overhead crane with a 3–5 t capacity and 12–18 m span, paired with a rotating lifting beam (1 t capacity, manual ±180° rotation) for cast iron plate flipping. The cabinet is handled with a nylon sling (80 mm width) to protect the finished surface. Lifting speed is two-speed (8 m/min no-load + 1.5 m/min under load).
Price Reference: LD single-girder crane (3 t / 15 m) is approximately $4,500–$8,900 per unit; the rotating lifting beam is roughly $740–$1,480 per set. Kelude's piano assembly solution comes standard with nylon slings and silicone pads, plus a C-hook spreader designed to prevent cabinet tipping.
Violin Workshop Light Lifting — Maple Stock Prep & Body Assembly
Violin making is precision woodworking. Individual instruments are extremely light (violin < 500 g, cello < 10 kg), but raw lumber (maple/spruce boards) is considerably heavier — a single bundle of maple boards weighs 50–200 kg. Wood drying requires controlled temperature and humidity, and the workshop generates significant sawdust.
Recommended Model: KBK flexible combination suspension crane (250–500 kg) covering the stock preparation area (board loading/unloading, drying rack transfer) and the body assembly zone. A pneumatic balancer (50 kg capacity) enables zero-gravity handling of instrument bodies, while a small jib crane handles board loading/unloading at the CNC woodworking station.
Price Reference: KBK system (250 kg) is approximately $2,200–$4,500 per set; pneumatic balancer (50 kg) runs $1,180–$2,200 per unit. Kelude's violin workshop solution includes a stainless steel hoist and dust-proof sealing as standard, suited for sawdust-heavy environments.
Brass Instrument Copper Sheet Handling — Coil Feeding & Welding Support
Brass instruments (trumpet/trombone/saxophone) are manufactured from copper sheet through cutting, rolling, welding, and polishing. Each copper coil weighs 200–500 kg (brass/phosphor bronze, 0.3–0.8 mm thickness) and must be lifted onto the cutting machine. Welding stations require assistance moving and aligning copper tubes (10–50 mm diameter, 1–2 m length). Copper dust is highly conductive, requiring explosion-proof configurations.
Recommended Model: BZD jib crane (500 kg–1 t, 2–3 m slewing radius) covering coil feeding at the cutting area, plus a mobile gantry (500 kg capacity) for welding stations. The motor is explosion-proof (ExdⅡBT4), and the electrical cabinet has IP55 sealing to prevent copper dust short circuits.
Price Reference: BZD jib crane (500 kg) is approximately $1,480–$2,960 per unit; mobile gantry (500 kg) runs $1,180–$2,200 per unit. Kelude's brass instrument solution includes explosion-proof electrical components and copper dust protective covers as standard.
Electronic Musical Instrument Assembly — Cleanroom Lifting for SMT & Final Assembly
Electronic musical instruments (digital pianos/synthesizers/electronic drums) are assembled primarily through SMT placement and final assembly. Finished units weigh 5–30 kg, and packed shipping cases weigh 50–100 kg. The assembly line demands high cleanliness (anti-static), as components are sensitive to electrostatic discharge. Production follows workstation rhythm rather than heavy-load requirements.
Recommended Model: KBK flexible modular crane (250 kg) with an intelligent lifting device (iLift), offering adjustable speeds from 0–12 m/min for precise electronic module placement. The workshop features ESD anti-static flooring with stainless steel chain grounding resistance below 10 Ω. Finished units are conveyed via a telescopic belt conveyor at line end.
Price Reference: KBK system (250 kg) is approximately $2,200–$4,500 per set; intelligent lifting device runs $1,480–$2,960 per unit. Kelude's electronic instrument solution includes anti-static wrapping and stainless steel materials as standard, meeting ESD/SMT workshop requirements.

Frequently Asked Questions
Q: How do you handle flipping and hoisting cast-iron piano frames?
A: Cast-iron frames weigh between 200 and 500 kg and require a 90° rotation for casting quality inspection. We recommend a manual rotating lifting beam (1–1.5 m in length, 1 t load capacity) with two lifting points. The procedure: ① Attach the beam's two lifting points to opposite ends of the frame; ② Use an LD overhead crane to raise it 100 mm off the floor; ③ Manually pull the rotation handle to turn the beam and frame 90°; ④ After inspection, rotate back to the original position. Kelude solutions come standard with anti-fall safety ropes.
Q: What protection is required for lifting equipment in a violin woodworking workshop?
A: In a sawdust-heavy environment, standard electric hoists can overheat and shut down when wood dust clogs the motor's cooling vents. We recommend: ① Motors with a Protection Rating (IP) of at least IP54; ② Galvanizing on crane rails to resist acidic corrosion from wood dust; ③ Control boxes placed outside the dusty area or housed in positive-pressure explosion-proof enclosures. Kelude's instrument workshop solutions include dust covers and scheduled cleaning as part of our maintenance service.
Q: Why do copper powder environments require explosion-proof cranes?
A: Copper powder is a conductive dust. When its concentration reaches the lower explosive limit (LSB) of approximately 30 g/m³, a spark can trigger an explosion. In copper tube polishing and welding areas, copper powder concentrations can reach 50–80 g/m³. For this reason, the crane's motor, electrical cabinet, and control buttons must all meet explosion-proof requirements (ExdⅡBT4). Kelude's explosion-proof hoists are manufactured with non-sparking aluminum bronze components.
Q: How is ESD protection implemented in an electronic musical instrument SMT workshop?
A: SMT workshops are highly sensitive to electrostatic discharge. The following measures are required: ① The grounding resistance of the crane rail and chain must be ≤10 Ω; ② Lifting spreaders must use anti-static nylon with a surface resistance of 10⁶–10⁹ Ω; ③ Operators must wear anti-static wrist straps; ④ Workshop humidity must be maintained at 40–60% RH. Kelude Heavy Industry provides grounding inspection reports.
