How to Choose a Crane for Packaging Machinery
Packaging machinery manufacturing (filling, sealing, labeling, and palletizing machines) relies primarily on light-load, precision assembly. We recommend an LD-type overhead crane (3–5t) paired with a KBK flexible suspension system (0.25–1t). Kelude's packaging industry solution covers the full process for all four equipment types.
Filling Machine Assembly Cranes: Stainless Steel Hopper & Weighing System Lifting
Core components of filling machines (liquid, powder, and granule types) include the hopper (stainless steel 304/316L, 200–1,000 kg), the weighing system (load cells plus filling nozzles, 50–300 kg), the conveyor system, and protective covers. Since filling machine assembly shops require cleanroom conditions (food/pharmaceutical grade), cranes must feature stainless steel construction or surface anti-corrosion treatment.
Recommended model: LD-type overhead crane, 3–5t with a 12–18 m span. Lifting the hopper and weighing system calls for a specialized spreader (nylon sling with stainless steel protective corners) to prevent scratching the stainless steel surfaces. Two-speed lifting is recommended (8 m/min no-load + 1 m/min under load).
Price reference: LD overhead crane, 3t/15 m: approximately $4,500–$8,900 per unit. Kelude's filling machine assembly solution comes standard with stainless steel anti-corrosion coating and nylon slings.
Sealing Machine Assembly Cranes: Precision Positioning of Heat-Seal Modules & Drive Systems
Core components of sealing machines (heat seal, ultrasonic, and induction types) include the heat-seal module (heating plate, pneumatic cylinder, temperature controller; 100–500 kg), the drive system (motor, gearbox, and chain; 50–200 kg), and the machine frame (welded stainless steel square tube; 200–600 kg). The assembly sequence starts with positioning the frame, followed by installing the heat-seal module and then the drive system.
Recommended model: KBK flexible suspension (0.25–0.5t) plus a BZD jib crane (0.25–0.5t). The KBK system covers every station on the assembly line — frame assembly, heat-seal module installation, drive system mounting, electrical wiring, and commissioning — with an independent trolley at each station. The BZD jib crane handles precise positioning of the heavier heat-seal modules.
Price reference: KBK system, 0.25t: approximately $3,000–$5,900 per set. Kelude customizes the rail length and hoist quantity for sealing machine assembly areas based on station cycle times.
Labeling Machine Assembly Cranes: Micron-Level Alignment of Precision Labeling Heads
Core components of labeling machines (pressure-sensitive, cold-glue, and heat-shrink sleeve types) center on the labeling head — label feed system, labeling roller, and servo motor — weighing 30–150 kg. Although the labeling head is relatively light, installation accuracy requirements are extremely demanding: positional error between label and target surface must stay within 0.5 mm, and labeling roller parallelism within 0.1 mm. Assembly requires operators to perform precision alignment by hand.
Recommended model: BZD jib crane, 0.25–0.5t with a 2–3 m slewing radius. Mounted directly above the labeling machine assembly station, the jib crane lets operators manually push and pull the spreader to move the labeling head into its installation position. The manual operation characteristics of a jib crane make it better suited for precision alignment than an electric crane.
Price reference: BZD jib crane, 0.25t: approximately $1,200–$2,200 per unit. Kelude's labeling machine assembly solution adds a micro-motion button to the jib crane hoist (each press moves hoisting/lowering ≤1 mm), meeting the precision alignment requirements of labeling heads.
Palletizer Assembly Cranes: Large Frame & Guide Rail Installation
Core components of palletizers (robotic and mechanical types) include the frame (welded square tube or structural steel, 500–3,000 kg), X/Y/Z-axis guide rails (precision linear rails, 2–6 m long, 100–500 kg), and the gripping mechanism (suction cups, fixtures, or electromagnets, 50–300 kg). Frame welding and assembly require a larger-tonnage crane.
Recommended model: LD-type overhead crane, 5–10t with a 15–24 m span. The frame welding area needs a single lift to complete tack-up, positioning, and full welding of the frame assembly; the selected tonnage must cover 1.5 times the frame weight as a safety factor. Guide rail installation requires lifting each 6 m rail onto the frame for precise alignment.
Price reference: LD overhead crane, 5t/18 m: approximately $7,400–$14,800 per unit. Kelude's palletizer assembly solution includes a multi-point lifting beam with 4–6 adjustable lifting points to accommodate frames and rails of varying lengths.

Key Parameters for Packaging Machinery
Kelude Service Advantages for Packaging Machinery
① Light-load precision solutions: Kelude's packaging machinery solutions are built around the KBK flexible system. Each workstation features an independent trolley with manual positioning accuracy of ≤0.5 mm, covering the full assembly process from filling and sealing to labeling and palletizing.
② Stainless steel surface protection: Protecting stainless steel surfaces on packaging machinery is a well-known industry challenge. Kelude addresses this with a standard triple-protection approach: nylon slings, silicone protective sleeves, and vacuum lifters — eliminating surface damage during assembly.
③ Full production line layout services: Kelude provides complete layout planning for packaging machinery manufacturing workshops — including crane type, capacity, rail routing, and workstation density for each station from filling to palletizing — ensuring zero interference between cranes and maximum workflow efficiency.
Frequently Asked Questions (FAQ)
Q: Why is a KBK system recommended over an LD overhead crane for packaging machinery assembly?
A: Core packaging workstations (sealing machines, labeling machines) are characterized by dense workstation layouts, high-frequency lifting (multiple small lifts per assembly cycle), light loads, and strict accuracy requirements. An LD overhead crane takes 20–40 seconds per start-stop cycle, making it unsuitable for workstation-level high-frequency lifting. With a KBK system, each workstation has its own independent trolley that can be manually positioned in 1–2 seconds. Kelude's recommendation: use LD overhead cranes (3–5 t) for workshop-level heavy transfers, and KBK systems (0.25–0.5 t) for workstation-level light lifting.
Q: How do you protect the stainless steel surface of a filling machine hopper?
A: Filling machine hoppers are typically made of 304/316L stainless steel with a surface roughness of Ra ≤0.8 μm (Ra ≤0.4 μm on food/pharma contact surfaces). Direct contact with wire rope during lifting leaves scratches that are unacceptable in food-grade equipment. The correct approach: ① Nylon sling under the hopper — sling width ≥50 mm, thickness ≥5 mm, with a silicone protective pad at the contact surface; ② Vacuum lifter — suitable for flat stainless steel plate hoppers (suction cup diameter 60–80 mm, holding force 100–200 kg per cup); ③ Dedicated support frame — the hopper is transported on a frame with polyurethane contact surfaces. Kelude's packaging industry solution includes nylon slings and silicone protective sleeves as standard.
Q: What is the payback period for cranes in the packaging machinery industry?
A: Using a plant producing 200 filling machines and 100 palletizers per year as an example: ① Filling machine assembly area — 1 LD 3 t crane (approx. $7,400); ② Sealing machine assembly area — 1 KBK system + 2 BZD hoists (approx. $8,900); ③ Labeling machine assembly area — 2 BZD hoists (approx. $3,000); ④ Palletizer assembly area — 1 LD 5 t crane (approx. $11,900). Total investment: approximately $31,200. Returns: hopper lifting time reduced by 50% (nylon sling vs. wire rope rigging); sealing machine assembly efficiency improved by 40% (no waiting with KBK); labeling head damage rate reduced by 80%. Payback period: approximately 10–14 months.
Q: How do I select the right crane capacity for palletizer frame welding?
A: Palletizer frames typically weigh 500–3,000 kg, but several factors must be considered when selecting crane capacity: ① Safety factor — ISO 4301 requires the crane's rated load to be at least 1.25 times the maximum lifted weight; we recommend using 1.5 times in practice; ② Lifting spreader weight — a multi-point lifting beam typically weighs 100–300 kg; ③ Future expansion — the palletizer product line may move toward heavier models. Therefore, we recommend a 5 t crane (covering current needs) with a 20% capacity reserve. If the frame weight approaches 3 t without spreader allowance, a 10 t crane is the better choice. Kelude offers precise capacity calculation services.
