Crane Selection Guide for Chemical Machinery Manufacturing
Cranes for chemical machinery manufacturing (reactors, heat exchangers, towers, storage tanks) must be configured based on equipment type. For reactor areas, QD/LH type cranes with corrosion-resistant coating (10–50 t); for heat exchanger areas, LD type cranes with stainless steel lifting spreaders (5–20 t); for tower fabrication, QD double-girder cranes for high-lift heavy loads (20–80 t) with explosion-proof Ex d IIB T4; and for storage tank areas, LH type cranes (10–30 t). The investment for a plant-wide solution ranges from $30,000 to $222,000.
Reactor Fabrication: Vessel Hoisting & Jacket Assembly
Reactors are the core equipment in chemical machinery manufacturing. We recommend QD-type double-girder or LH-type overhead cranes with capacities from 10 to 50 tons. Given the high weld quality and assembly accuracy required for reactor jackets, the crane must work in tandem with roller beds and welding positioners. Kelude's reactor-area cranes come standard with variable frequency hoisting (0.5–8 m/min), allowing slow-speed rotation (≤2 m/min) during shell flipping to prevent undue stress on the weld seam.
Jacket assembly (half-pipe or full jacket) involves lifting prefabricated jacket components into position around the vessel shell before welding. Kelude's QD-type cranes feature variable-frequency drive (VFD) on both the crane bridge and trolley, effectively minimizing load sway. For stainless steel reactors, lifting spreaders must be made of stainless steel or nylon-coated material. The investment for a reactor-area crane solution typically ranges from $30,000 to $119,000.
Heat Exchanger Manufacturing: Dedicated Crane Setup for Tube Bundle Assembly
Shell-and-tube heat exchanger tube bundles are assembled by threading hundreds of tubes through tube sheets and then expanding or welding them into place, with weights ranging from 5 to 20 tons. We recommend LD-type cranes with capacities of 5–20 tons. Kelude's heat exchanger crane solution includes a dedicated tube bundle lifting spreader (C-type or spreader beam design) with adjustable suspension point spacing along the bundle length. A separate 1–3 ton jib crane is recommended for the tube sheet machining area. The investment for a heat exchanger area crane typically ranges from $22,000 to $59,000.
Tower Fabrication: QD Double-Girder Solution for Heavy Loads & High Lifts
Towers range from 1 to 6 meters in diameter, with individual tower sections weighing between 10 and 80 tons. We recommend QD-type double-girder cranes with capacities of 20–80 tons and lifting heights of 18–24 meters. Kelude's QD-type tower cranes come standard with a twin trolley configuration (80 t + 10 t): the main trolley handles heavy loads, while the auxiliary trolley manages internals and tooling. The investment for a complete QD-type double-girder crane ranges from $44,000 to $222,000.
Storage Tank & Pressure Vessel: Plate Rolling and Welding Setup
Atmospheric storage tanks typically weigh between 10 and 30 tons. We recommend LH-type cranes with capacities of 10–30 tons. Kelude's storage tank area solution typically requires an investment of $30,000 to $89,000. The total investment for a complete chemical machinery plant crane solution ranges from $30,000 to $222,000.

Explosion-Proof Crane FAQ: Key Questions Answered
Q: Is an explosion-proof crane required for chemical machinery manufacturing?
A: It depends on whether flammable and explosive media are involved. Pure mechanical processing does not require one. We recommend reserving explosion-proof provisions during the workshop design phase.
Q: Should a tower fabricator choose a single-trolley or twin-trolley crane?
A: Twin trolleys are recommended for capacities above 20t, typically configured as an 80t main trolley plus a 10t auxiliary trolley. Kelude's QD-type twin-trolley cranes are already serving multiple tower fabrication plants.
Q: What are the lifting spreader requirements for heat exchanger tube bundles?
A: Adjustable suspension points and variable suspension point spacing are essential. Stainless steel tube bundles require nylon padding for protection. Kelude offers C-hook spreaders for tube bundles in the 5–20t range.
Q: How long does a full-plant solution design take?
A: The solution is delivered within 7–12 days. Manufacturing plus installation typically takes 50–120 days. Site surveys and design work are provided free of charge.
