Crane Solutions for Military Radar Manufacturing
Military-grade radar electronics manufacturing (radar antennas 1–8 t/unit, electronic shelters 1–3 t/unit, power supply cabinets 200–800 kg/unit, command vehicle superstructures 3–5 t) demands extreme precision and safety. Recommended configuration: QD double-girder 10 t VFD + LD single-girder 3–5 t synchronized tandem lifting + KBK + intelligent hoist. Kelude's military industry solutions are fully GJB9001 certified.
1. Radar Antenna Assembly — Precision Hoisting for Parabolic & Phased-Array Systems
Radar antennas (parabolic or phased-array) weigh 1–8 t per unit and feature an aluminum honeycomb or carbon-fiber skin over a metal frame. The surface coating (radar-absorbing material) is extremely fragile—any scratch can compromise electrical performance. Antenna assembly must be performed in a cleanroom (Class 10,000) with controlled temperature and humidity.
Recommended model: QD-type double-girder bridge crane, 10 t capacity with a 15–22 m span, equipped with Variable Frequency Speed Control for creep speeds of ≤1 m/min to support precision alignment. Use nylon woven lifting slings (100 mm wide, 10 t capacity, tensile strength ≥200 kN) with silicone protective sleeves, plus a specialized antenna spreader with multiple lifting points spaced ≤1 m apart to prevent deformation.
Price reference: QD double-girder 10 t / 18 m: approximately $18,000–$30,000 per unit; VFD adds roughly 15%. Kelude's radar antenna solution includes a force sensor on each lifting sling (accuracy ±2%), with an automatic alarm triggered when corner load deviation exceeds 10%.
Electronic Shelter Final Assembly—EMI-Shielded Enclosure Mating
Electronic shelters (1–3 t) are electromagnetic shielding enclosures (aluminum alloy or steel plate, shielding effectiveness ≥60 dB). Panel joints must maintain electromagnetic sealing integrity—conductive gaskets (beryllium-copper finger stock) are applied at seams with screw spacing ≤50 mm. The shelter mating process requires two cranes operating in synchronized tandem lifting to prevent housing deformation.
Recommended model: Two LD single-girder electric cranes, 3–5 t each, fitted with wireless synchronous control modules (master–slave mode, slave follows master with ≤200 ms latency). The mating area features four locating guide posts (Φ50 mm stainless steel) that guide the shelter during slow descent.
Price reference: Two LD 3 t cranes at approximately $3,000–$6,000 each, plus $1,500–$3,000 for the synchronization module set. Kelude's shelter solution includes a synchronous control system with automatic shutdown protection if synchronization is lost.
Power Equipment Handling—Precision Power Cabinets and UPS Transport
Military-grade power cabinets, UPS units, and similar equipment weigh 200–800 kg each and contain sensitive electronic components (IGBTs, transformers, capacitor banks). Handling requires shock-proofing (acceleration ≤3 g) and tilt prevention (inclination ≤10°). The assembly area must have anti-static (ESD) flooring.
Recommended model: KBK flexible modular crane system with an intelligent lifting device (iLift 500 kg) providing hoisting/lowering acceleration of ≤0.5 m/s² and automatic load-holding when suspended. The finished-goods area uses AGVs (1 t capacity, with shock-absorbing platforms) to interface with the KBK system for offloading.
Price reference: KBK system (500 kg): approximately $3,000–$6,000 per set; iLift: $2,200–$4,500 per unit. Kelude's power equipment solution includes acceleration testing reports and ESD grounding verification.
Command Vehicle Integration—Shelter and Antenna Installation
Command vehicle retrofitting involves mounting the shelter assembly onto the vehicle (3–5 t) and erecting communication antennas (50–200 kg each). Interior modification is completed first, then the vehicle is moved outside for antenna installation and testing. The workshop entrance requires a clear height of ≥5 m to accommodate vehicle access. The outdoor test area must have ground anchors for vehicle securing.
Recommended model: Indoors: double-girder bridge crane, 5–10 t, covering shelter hoisting onto the vehicle. Outdoors: mobile gantry crane (2–5 t) or fixed jib crane (1 t) for rapid antenna erection and testing. The test area floor is fitted with ground anchors (M24×300 mm, load capacity ≥50 kN) for vehicle restraint.
Price reference: Indoor QD 5 t: approximately $12,000–$22,000 per unit; outdoor jib crane: $1,500–$3,000 per unit. Kelude's command vehicle solution includes outdoor ground anchor design and vehicle securing methodology.

FAQ: Radar & Shelter Lifting
Q: How do you prevent coating damage when lifting radar antennas?
A: The radar-absorbent coating (0.5–2 mm thick) on antenna surfaces can alter the radar cross-section (RCS) if damaged. Our protection measures include: ① silicone pads lining the slings (thickness ≥5 mm, Shore hardness A30–40); ② evenly distributed lifting points (max. 1 point per m²); ③ lifting speed ≤2 m/min; ④ air cushion buffers placed beneath the load during transport. Kelude antenna spreaders come with silicone lining and tension distribution indicators.
Q: How is safety ensured during tandem lifting of electronic shelters with two cranes?
A: Tandem lifting safety measures: ① wireless synchronization module — the master crane's remote control operates both cranes, with the slave crane following within ≤200 ms of any master position change; ② sync-loss protection — both cranes stop immediately if the signal is interrupted or deviation exceeds 20 mm; ③ independent limit switches and overload protection on each crane; ④ tandem lifting test — no-load test run followed by a 50% load test before first use. Kelude's solution includes a full commissioning report.
Q: What are the security requirements for a military workshop?
A: Military workshops have strict confidentiality requirements: ① Electronic control system — a physically isolated control setup (wired remote control or pushbutton station) is recommended, with no external network connectivity; ② No radio remote control — to prevent signal interception or interference; ③ Positioning accuracy records — lifting and transport records for each batch must be retained for 15 years or more; ④ Weekly safety inspections — check bolt torque on all crane connection points (M20 bolts: 300 Nm). Kelude offers a non-networked control system for military applications.
Q: What door height is required for a command vehicle conversion workshop?
A: Command vehicles (chassis + shelter) typically have an overall height of 3.5–4.5 m. Add the crane hook clearance — the hook's lowest point must clear the shelter installation height plus a 500 mm safety distance. This means the workshop clear height should be at least 9 m, with a door height of 5.5 m or more. If the existing clear height is insufficient (below 7 m), a pit-style conversion (shelter lowered into a floor pit) is a viable alternative. Kelude provides solutions for facilities with limited headroom.
