Crane Configurations for Fire Equipment Manufacturing
Fire equipment manufacturing spans an enormous range of load capacities—from 1–3 t water tank assemblies on fire trucks handled by double-girder cranes, to fire extinguisher cylinders weighing ≤20 kg moved on KBK chain conveyor lines, light-load alarm devices on AGVs, and 200–600 kg bundles of sprinkler pipe fittings lifted by jib cranes. Kelude’s fire protection solutions are tailored by product category, covering everything from heavy vehicles to electronic modules.
Fire Truck Refurbishment: Water & Foam Tank Hoisting and Body Assembly
The core process in fire truck refurbishment involves positioning the chassis, hoisting the water/foam tank (carbon steel or stainless steel, 1–3 t), lifting the pump set (200–500 kg), installing piping, and completing the electrical integration. The tank positioning accuracy requirement is ≤5 mm for alignment with the chassis mounting holes. The workshop typically has a span of 16–22 m and a clear height of 8–12 m.
Recommended Model: QD Type double-girder bridge crane with a lifting capacity of 5–10 t and a span of 16–22 m. Variable Frequency Speed Control (slow speed ≤2 m/min) ensures precise positioning of the tank and pump set. A C-hook spreader (3 t capacity, 500 mm opening height) is used to lift the tank from underneath. A pit of 0.8–1.2 m deep in the refurbishment area facilitates access beneath the chassis.
Price Reference: Approximately $12,000–$22,000 per unit for a QD double-girder crane (5 t, 18 m span). Kelude Heavy Industry's fire truck solution includes a specialized tank spreader (rubber-lined C-hook with anti-rotation chain).
Fire Extinguisher Cylinder Line: Cutting, Rolling, Welding, and Hydrostatic Testing
Fire extinguisher cylinders (carbon steel, 1.5–3 mm wall thickness, 3–20 kg each) are produced on a high-speed assembly line with a cycle time of ≤30 seconds per cylinder. The line includes steel plate cutting, rolling, longitudinal seam welding, necking, hydrostatic testing, and painting. Mold changes (200–500 kg per set) require lifting assistance.
Recommended Model: A KBK Flexible Crane System (500 kg) covers the mold storage area and changing stations. The production line is equipped with a chain conveyor (600 mm width, 5–15 m/min adjustable speed) for cylinder transfer. The hydrostatic testing area uses a 250 kg electric hoist to handle test fixtures.
Price Reference: Approximately $3,000–$6,000 per KBK system (500 kg), and $700–$1,500 per electric hoist (250 kg). Kelude Heavy Industry's fire extinguisher line solution includes a quick-change mold cart (mold change in ≤15 minutes).
Alarm Device Electronics Plant: SMT and Control Cabinet Assembly
Alarm devices (smoke detectors, heat detectors, alarm control panels) primarily involve SMT electronic assembly and sheet metal fabrication. The control cabinets (50–100 kg each) house the main control board, power supply, and communication modules. The SMT area is highly automated (SMT placement machines, reflow ovens, automated optical inspection), with materials delivered by AGVs.
Recommended Model: A light-duty KBK suspension rail (250 kg) covers the control cabinet assembly line and aging test area. The aging racks (multi-tier, 50 kg per shelf, total load ≤300 kg) use a 250 kg electric chain hoist to lift multiple trays. No crane is required for the SMT line.
Price Reference: Approximately $2,200–$4,500 per KBK system (250 kg), and $400–$900 per chain hoist (250 kg). Kelude Heavy Industry's alarm device solution includes an anti-static lift platform integrated with the aging racks.
Sprinkler System Pipe Fittings: Sawing, Threading, and Assembly
Sprinkler steel pipes (galvanized, DN20–DN150, 3–6 m per piece) go through sawing, threading, assembly, and pressure testing. Each bundle of pipes weighs 200–600 kg (10–20 pipes per bundle). Finished pipe fittings are batch-packed for shipment.
Recommended Model: A BZD jib crane (500 kg, 2.5–3 m slewing radius) covers the pipe loading area, lifting entire bundles onto a V-rack (15° inclination) for automatic feeding into the machining station. A mobile gantry (500 kg capacity) handles finished pipes in the assembly area. A small jib crane assists with bundling in the packing area.
Price Reference: Approximately $1,500–$3,000 per jib crane (500 kg), and $1,200–$2,200 per mobile gantry (500 kg). Kelude Heavy Industry's sprinkler solution includes a V-rack automatic feeding system.

FAQ
Q: What are the accuracy requirements for hoisting fire truck water tanks?
A: Fire truck water tanks have mounting holes on the bottom (hole spacing tolerance ±2mm) that align with mounting bolts on the chassis frame. Hoisting accuracy requirements: ① When the tank is lowered to 100mm above the chassis, use a pry bar to fine-align the mounting holes; ② Once aligned, lower slowly and stop for inspection after the bolts enter the holes; ③ After all bolts are inserted, tighten in a diagonal sequence (M16 bolt torque: 180~220Nm). Kelude's solution includes guide cones on the tank (30° taper) to assist with automatic centering.
Q: How does crane support work for hydrostatic testing of fire extinguisher cylinders?
A: Hydrostatic testing of fire extinguisher cylinders (test pressure 2.5~3.5MPa, hold time ≥1 minute) requires crane support in three areas: ① Test fixture handling—fixtures weigh approximately 30~50kg, and each test batch processes 8~12 cylinders, requiring an Electric Hoist; ② Non-Conforming Product handling—cylinders that fail testing must be moved to a quarantine area; ③ Mold change—upper and lower test dies require a KBK or jib crane. Kelude provides quick-clamping tooling to reduce hoisting frequency.
Q: What lifting spreader is used for handling complete alarm control panels?
A: For alarm control panels (50–100 kg each, 600×600×1800 mm), we recommend the following handling methods: ① KBK system with a Balancer and hook — manually pushed to move between the assembly line and the aging area; ② Retrofitting heavy-duty casters on the cabinet base (200 kg capacity per caster) for manual movement over short distances; ③ An electric roller conveyor line for finished units coming off the production line. Note: The electronic modules inside the panel must not experience acceleration exceeding 5g during handling. Kelude offers an anti-vibration spreader as part of the solution.
Q: What is the optimal inclination angle for a spray pipe loading rack?
A: The inclination angle of a V-type loading rack directly affects how smoothly and safely pipes roll off automatically: ① Below 10° — pipes will not roll off on their own and require manual pushing; ② Between 10° and 20° — pipes roll off automatically with slight vibration (15° is recommended); ③ Above 20° — pipes roll too fast and may overshoot the work position, creating a safety hazard. The rack length should be designed to accommodate the longest pipe specification (6 m plus 500 mm allowance). Kelude offers racks with an adjustable inclination angle (lockable anywhere from 5° to 25°).
