Crane Selection for Pharmaceutical Equipment Manufacturing
Pharmaceutical equipment manufacturing (reactors 1–8 t/unit, dryers 500 kg–3 t, granulators ≤2 t, filling machines ≤3 t) requires GMP compliance and stainless steel material. Recommended configuration: QD double-girder 10–20 t with stainless steel soft lifting spreaders, plus LD single-girder 3–5 t and KBK 2 t. Kelude's pharmaceutical solutions feature GMP-compliant design throughout with Ra ≤0.4 μm surface finish.
Reactor Welding & Assembly — Shell Plate Rolling and Inner Wall Polishing
Pharmaceutical reactors (stainless steel 304/316L or glass-lined) typically weigh between 1 and 8 tons. After shell plate rolling and welding, the inner surface requires mirror-grade polishing to Ra≤0.4μm for pharmaceutical-grade applications. Glass-lined vessels undergo a separate process where a glass enamel layer is fused to the steel shell at 800–900°C. Any scratching during welding or polishing is strictly prohibited.
Recommended Equipment: QD-type double-girder bridge crane, 10–20t capacity with a 14–20m span, fitted with soft nylon slings (100mm wide, silicone-lined) and a rubber-coated C-hook spreader. Shell rotation is handled by a welding positioner (5t capacity). A dedicated jib crane in the polishing area assists with loading and unloading the polishing machine.
Price Reference: QD double-girder crane (10t/16m): approximately $15,000–$27,000 per unit. Soft lifting gear: roughly $750–$1,500 per set. Kelude's reactor solution comes standard with soft slings and stainless steel corner guards to protect the vessel surface.
Dryer Manufacturing — Fluid Bed/Vacuum Chamber Welding and Leak Testing
Dryers (fluid bed, vacuum, or spray type) range from 500kg to 3 tons. The stainless steel chambers demand high welding accuracy with weld seam roughness held to Ra≤1.6μm. Each chamber must pass a pneumatic leak test at 0.3–0.5MPa with pressure held for 24 hours and allowable pressure drop ≤5%. Chamber rotation for welding requires a 360° positioning fixture.
Recommended Equipment: LD-type single-girder electric crane, 3–5t capacity with a 12–18m span, paired with a welding positioner (3t capacity) for full 360° rotation during welding. A 500kg jib crane in the leak-test area assists with end-cover installation. A pneumatic pressure test pump (0–1MPa) is also specified.
Price Reference: LD single-girder crane (3t/15m): approximately $4,500–$9,000 per unit. Welding positioner: roughly $3,000–$6,000 per unit. Kelude's dryer solution includes stainless steel slings and gasket positioning fixtures.
Granulator Precision Assembly — Mill Blade and Screen Installation
Granulators (wet or dry granulation) weigh up to 2 tons. Core components include the mill blade (stainless steel, dynamically balanced to G2.5, operating speed 500–3,000 rpm) and the screen (stainless steel woven mesh, 0.5–3mm openings). Blade-to-screen clearance must be held within ≤0.1mm. The granulation chamber is mirror-polished to Ra≤0.6μm.
Recommended Equipment: KBK flexible modular crane (2t) with a precision lifting platform (height adjustment accuracy ±1mm) for granulation chamber assembly. Blade installation uses a manual hydraulic lift cart (100kg capacity, lifting height 0.5–1.2m) to prevent edge damage.
Price Reference: KBK system (2t): approximately $6,000–$12,000 per set. Precision lifting platform: roughly $1,200–$2,200 per unit. Kelude's granulator solution includes anti-collision soft blade holders.
Filling Machine Precision Assembly — Nozzle and Metering Pump Alignment
Filling machines (liquid or powder filling) weigh up to 3 tons. Filling accuracy must reach ±0.5% for liquids and ±1% for powders. Nozzle-to-pump installation alignment tolerance is ≤0.2mm. Assembly takes place in an ISO Class 7 cleanroom; all product-contact parts are 316L stainless steel with PTFE seals.
Recommended Equipment: LD-type single-girder bridge crane, 3–5t capacity with a 10–15m span, covering complete machine handling. Nozzle installation uses a pneumatic balancer (50kg) for fine positioning. Metering pump calibration is performed with a laser alignment tool (0.01mm accuracy). The ISO Class 7 cleanroom is limited to the nozzle assembly area.
Price Reference: LD single-girder crane (3t/12m): approximately $3,000–$7,500 per unit. Pneumatic balancer: roughly $1,200–$2,200 per unit. Kelude's filling machine solution includes 316L stainless steel spreaders and cross-cleanroom transfer handling.

Frequently Asked Questions
Q: How do you protect the glass-lined layer of reactors during hoisting?
A: The glass-lined layer (0.8–2mm thick) has high hardness but poor impact resistance and is highly brittle. Key hoisting protection measures: ① Never use wire rope — direct contact with the glass-lined surface causes chipping and cracking; ② Use nylon slings with silicone pads — sling width ≥80mm with a 5mm silicone pad lining; ③ Keep sling angle deviation ≤5 degrees to prevent local stress concentration from tilting; ④ Limit lifting speed to ≤3m/min for smooth starts and stops. Kelude Heavy Industry offers a dedicated glass-lined hoisting kit (including imported silicone pads) for reactor applications.
Q: What is the pressure-holding standard for dryer chamber leak testing?
A: For pharmaceutical dryer chamber leak testing: ① Test pressure — 1.25 times the design pressure (typically 0.3–0.5MPa); ② Pressure-holding duration — ≥24 hours; ③ Acceptance criteria — pressure drop ≤5% of test pressure (e.g., from 0.4MPa to ≥0.38MPa within 24 hours); ④ Test medium — dry compressed air or nitrogen (moisture content ≤10ppm). Kelude Heavy Industry provides quick-locking end cover mechanisms (8 bolts hand-tightened in ≤5 minutes).
Q: How is the blade-to-screen clearance (requirement ≤0.1mm) inspected and adjusted?
A: Test methods for blade-to-screen clearance (requirement ≤0.1mm): ① Feeler gauge method — use a 0.1mm feeler gauge at 4 points around the circumference; if the gauge passes through, the clearance fails inspection. ② Dial micrometer method — rotate the blade one full turn and record the minimum clearance reading. ③ Optical imaging method — use an industrial microscope to measure the distance between the blade edge and the screen. Adjustment method: add or remove shims (0.05mm each) at the bearing housing of the blade shaft. Kelude's granulator package includes a feeler gauge and dial micrometer inspection tool kit.
Q: Why does filling head assembly require an ISO Class 7 cleanroom?
A: The assembly environment for filling heads (which come into direct contact with liquid or powder pharmaceuticals) must meet the following requirements: ① ISO Class 7 cleanroom conditions to minimize microbial contamination risk — airborne particles ≥0.5μm must not exceed 352,000 particles/m³. ② Temperature and humidity control — 20–26°C / 40–60% RH to prevent thermal expansion or contraction of the filling head seals. ③ Positive pressure air supply (pressure differential ≥5Pa vs. adjacent areas) to keep contaminants from entering. In Kelude's filling machine design, the assembly area cleanroom is independently enclosed, and the crane operates only outside the cleanroom.
