Overhead Crane for Auto Plants: Stamping, Welding & Assembly

In brief: Kelude Heavy Industry provides crane configuration solutions for traditional automotive OEMs, covering all four process workshops—stamping, welding, painting, and final assembly. With lifting capacities from 2 to 50 t and spans from 12 to 36 m, the complete-plant hoisting investment typically ranges from approximately $74,000 to $740,000. The stamping shop is equipped with double-girder bridge cranes (20–50 t) for die changes, the welding shop uses underslung spot welders paired with KBK systems (1–3 t), the painting shop employs explosion-proof cleanroom cranes (2–5 t), and the final assembly shop uses light-duty underslung cranes and KBK flexible systems (0.5–3 t)—all engineered to meet the high-takt, high-precision, multi-station hoisting demands of automotive production lines.

A: Our cranes are designed to meet or exceed international safety standards, including ISO 12480 for crane safety and IEC 60204-32 for electrical installations. We also offer configurations that comply with specific regional or industry requirements.

Q: Can you provide cranes for hazardous environments?
A: Yes, we manufacture explosion-proof cranes and hoists designed for use in hazardous areas. These are built with specialized components and sealing methods to ensure safe operation in potentially explosive atmospheres.

Q: What is the typical lead time for a custom crane?
A: Lead times vary depending on the complexity and specifications of the crane. A standard crane can typically be delivered within 8-12 weeks, while custom-engineered solutions may require a longer timeline. Please contact our sales team for a specific quotation.

Q: Do you offer installation and commissioning services?
A: Absolutely. Our team of experienced technicians can handle the complete installation and commissioning process. We also provide operator training and comprehensive maintenance packages to ensure safe and efficient operation.

Q: What is your warranty policy?
A: We offer a standard warranty on all our crane components and workmanship. The specific terms and duration of the warranty can be detailed in the sales contract. We also offer extended warranty options for additional peace of mind.

Q: How do I request a quote for a crane system?
A: You can request a quote by contacting our sales department through the website or by email. Please provide details such as capacity, span, lifting height, and application, and our team will respond with a tailored solution and pricing.

Stamping and Body Shop Crane Solutions

A: In traditional automotive stamping plants, die changes center on large dies, with LH-type 10 t–20 t electric hoist bridge cranes covering the press lines. In the body shop, LD/LH-type 3 t–10 t cranes provide full coverage across all welding stations.

Paint Shop and Final Assembly Crane Solutions

The paint shop requires Ex tb explosion-proof protection, just as in EV manufacturing. In final assembly, QD-type 10 t–32 t double-girder bridge cranes equipped with anti-sway control handle the hoisting of engines (200–500 kg) and gearboxes (100–200 kg).

Kelude Heavy Industry — Service Advantages

Kelude Heavy Industry has spent years specializing in overhead crane systems for automotive manufacturing plants. We deliver complete lifting solutions covering all four production shops—stamping, body shop, paint shop, and final assembly—for traditional internal combustion engine (ICE) vehicle factories. Our equipment is engineered to meet the demanding JPH takt rate requirements of automotive production, and we have served more than 20 automotive manufacturers across China.

Stamping Press Die Change Solutions
Rapid die changes (individual dies weighing 5–25 t) are critical to stamping line productivity. Kelude configures 20–50 t double-girder bridge cranes with hydraulic quick-action die clamps and automatic die shuttle cars, cutting die change time from the traditional 15–20 minutes down to 3–5 minutes and boosting stamping line utilization by 8%–12%.
Multi-Model Body Shop Line Solutions
When 2–4 vehicle models share a single body shop line, Kelude deploys KBK flexible suspension systems integrated with robotic welding stations, with KBK rails running the full length of the welding line. Doors and closures are handled by KBK cranes fitted with vacuum suction lifters—switching models only requires changing the suction cup fixtures, with no need to stop the entire line.
Explosion-Proof Paint Shop Solutions
Paint booths are classified as explosive dusty environments (Ex Zone 22) and also demand strict cleanliness. Kelude uses stainless steel explosion-proof electric hoists (Ex tb IIIC T120°C) paired with stainless steel rails and dust-proof sealed motors—all with smooth, easy-to-clean surfaces and no paint accumulation dead spots. KBK systems are installed along the paint conveyor line for the erection and dismantling of spray hangers.

Frequently Asked Questions (FAQ)

Q: How is the maximum lifting capacity determined for die changes in a stamping workshop?
A: The die weight is calculated based on the heaviest die (typically the side-panel die) multiplied by a 1.25 safety factor. For a B-class sedan, for example, the heaviest die is the side-outer-panel die (18–25 t), which requires a 25/5t or 32/5t double-girder bridge crane. Kelude recommends full crane rail coverage between the die storage area and the presses to minimize floor space occupied by die transfer trolleys.
Q: Why is the suspension point spacing shorter for KBK systems in welding workshops than in logistics warehouses?
A: KBK systems in welding workshops must support welding gun cables (weighing 5–8 kg per meter) and balancers (5–15 kg each), resulting in uneven load distribution. Kelude shortens the suspension point spacing from the standard 3 m to 2–2.5 m in welding workshops to ensure smooth, jam-free cable drag chain movement. Sliding cable trolleys are also configured to automatically pay out and retract the cable as the welding gun moves.
Q: How are explosion protection grades classified for workshop cranes in a painting facility?
A: Spray-painting booths (where combustible paint mist is present) are classified as Explosive Zone 22 (combustible dust/fiber atmosphere), requiring cranes to meet Ex tb IIIC T120°C explosion-proof grade. Paint-mixing rooms (where organic solvent vapors are present) fall under Zone 1 or Zone 2, requiring Ex d IIB T3~T4 explosion-proof grade. Kelude precisely configures the explosion protection class based on the workshop zone classification drawings, preventing over-specification that would drive up costs.
Q: What's the difference between a KBK system on a final assembly line and a standard electric hoist?
A: A KBK system on a final assembly line is a lightweight solution combining manual pushing with electric lifting (lifting capacity 125–500 kg), whereas a standard electric hoist is fully electric. The KBK advantages: ① Flexible operation—workers can manually push the lifting spreader along the crane rail to any workstation; ② Compact footprint—the KBK rail height is only 100–120 mm, ideal for low-headroom workshops; ③ Enhanced safety—no cable festoon system required, eliminating the risk of strand break or short circuit from moving cables.
