Crane Selection Guide for Ropeway Manufacturing
Ropeway manufacturing involves four key components—tower sections (3–8 t per section), runway beams (1–2 t per beam), cabins (1–1.5 t), and drive units (2–5 t)—each with distinct weight and accuracy requirements. The recommended configuration is a QD double-girder crane (10–20 t) with a C-hook spreader, paired with an LD single-girder crane (3–5 t) and a KBK system (2 t). Kelude's industry solution covers all components.
Heavy Tower Column Lifting: Welding & Tack-Up of Steel Tube Truss Sections
Cableway tower columns use a steel tube truss structure, with individual sections measuring 6–12 m in length and weighing 3–8 t. The welding process involves: steel tube cutting, tack-up, girth welding, and flange machining. Flange alignment between sections demands high accuracy (diagonal error ≤ 2 mm). The workshop is typically a heavy-duty factory building (span 18–24 m, clear height 12–16 m).
Recommended Model: QD-type double-girder bridge crane, 10–20 t / span 18–24 m, fitted with a C-hook spreader or self-balancing spreader beam (4–6 lifting points). The C-hook spreader slides under the section to enable flipping and tack-up of long workpieces. The welding area is equipped with a CNC welding positioner (5 t capacity, ±360° rotation), while the crane handles loading and unloading of workpieces.
Price Reference: QD double-girder 10 t / 20 m approx. $18,000–$30,000 per unit; self-balancing spreader beam approx. $1,500–$4,500 per set. Kelude's tower column solution comes standard with remote control operation and anti-sway control, achieving section tack-up accuracy of ≤ 1 mm/m.
Precision Track Rail Lifting: End Machining & Installation
Cableway track rails are 8–12 m long and weigh 1–2 t each. The ends require milling to achieve a mating surface flatness of ≤ 0.2 mm. Rails are typically made of weathering steel and need anti-rust treatment after machining. Precision alignment is essential during installation, with end connection hole spacing tolerance of ≤ 0.5 mm.
Recommended Model: LD-type single-girder electric crane, 3–5 t / span 12–18 m, fitted with a multi-point lifting beam (4 lifting points, adjustable spacing 2–3 m). The machining area is supported by V-type support stands and a lifting magnet for quick rail flipping. Dedicated nylon slings prevent damage to machined surfaces.
Price Reference: LD single-girder 3 t / 15 m approx. $4,500–$9,000 per unit; multi-point lifting beam approx. $750–$1,500 per set. Kelude's track rail solution features an adjustable lifting point beam (lifting point spacing 1–4 m, lockable at any position) to accommodate rails of varying lengths.
Cabin Manufacturing & Assembly: Aluminum Frame & FRP Skin
Cableway cabins (6–8 or 15 seats) feature an aluminum alloy welded frame (300–800 kg) with a fiberglass reinforced plastic (FRP) skin (200–500 kg per set). Glass panels are tempered safety glass (50–100 kg per piece). Assembly requirements: frame welding accuracy ≤ 2 mm, and glass panels must be handled gently to prevent spontaneous breakage.
Recommended Model: KBK flexible modular crane, 2 t, covering the cabin assembly line (frame welding, skin installation, glass fitting, interior assembly, testing). A pneumatic balancer (50 kg) assists with precise positioning of fragile glass components. The end of the assembly line features an electric flat car for transfer to the paint shop.
Price Reference: KBK system 2 t approx. $6,000–$12,000 per set; pneumatic balancer approx. $1,500–$3,000 per unit. Kelude's cabin solution includes a vacuum lifter as standard at the glass installation station (200 kg suction per cup, dual-circuit protection).
Precision Drive Unit Assembly: Motor/Gearbox Shaft Alignment
Cableway drive units (main motor + gearbox + drive wheel) weigh 2–5 t per unit. Shaft alignment between the gearbox output shaft and drive wheel hub must be within ≤ 0.1 mm. The assembly process includes gear mesh inspection and bolted connections tightened to a specified torque (torque accuracy ±5%). The test bench conducts both no-load and loaded operation tests.
Recommended Model: QD-type double-girder bridge crane, 5–10 t, with variable-frequency speed control hoisting mechanism (creep speed ≤ 0.5 m/min) for millimeter-level positioning. The assembly area features a precision platform (T-slot floor rail, flatness ≤ 0.05 mm/m). Drive wheel installation uses a hydraulic torque wrench (max torque 5,000 Nm).
Price Reference: QD double-girder 5 t / 18 m approx. $12,000–$22,000 per unit; VFD adds approx. 15%. Kelude's drive solution includes a micro-motion button (each press lifts/lowers ≤ 1 mm) to meet precision gear alignment requirements.

Frequently Asked Questions
Q: How do tower section welding positioners coordinate with overhead cranes?
A: The welding sequence for tower sections (6–12 m long, 3–8 t) is: ① The QD overhead crane lifts the section onto the positioner's V-block; ② Tack welding secures it before the hook is released; ③ The positioner rotates 360° for circumferential seam welding; ④ The QD crane removes the finished piece. The key is ensuring the spreader doesn't interfere with positioner rotation—C-hook spreaders or special lifting beams are recommended. Kelude provides integrated positioner-plus-crane solutions.
Q: How do you prevent deformation when lifting runway beams with a high slenderness ratio (length/cross-section > 30)?
A: Runway beams have small cross-sections and long lengths (8–12 m), making single-point lifting prone to noticeable deflection. Solutions include: ① Using a multi-point (4–6 lifting points) spreader beam with suspension point spacing ≤ 2.5 m; ② Equipping each point with manually adjustable wire rope lengths to ensure even load distribution; ③ Keeping lifting speed ≤ 3 m/min to avoid impact loads. Kelude standardly provides adjustable lifting point cross beams.
Q: How can damage to fiberglass cabin skins be avoided during handling?
A: The FRP skin (weighing 200–500 kg) is prone to surface scratches and is highly brittle. Recommended approach: ① Use a vacuum lifter with 4–6 suction cups (80 mm diameter each) to distribute the holding force across different skin areas; ② Keep lifting and transport speed at ≤5 m/min; ③ Place foam spacers between stacked skins. Kelude Heavy Industry's vehicle body solution includes a vacuum suction lifter set with polyurethane protective pads.
Q: What is the inspection method for gear alignment in the drive unit?
A: Shaft alignment procedure for the gearbox and drive wheel: ① Rough alignment — use a steel straightedge to check the gap between the two shaft end faces and adjust to the design value ±1 mm; ② Fine alignment — use a laser alignment tool (accuracy 0.01 mm) to measure radial and axial deviation; ③ Adjust the shim thickness to bring the error to ≤0.1 mm. Kelude Heavy Industry's solution includes a laser alignment report.
