Factory-inspected units stored at our 30+ acre Huai'an yard, packed for international rail freight via Khorgos/Alashankou with complete non-destructive test (NDT) reports.
Under the ambitious "Uzbekistan 2030" Strategy and unprecedented foreign direct investment (FDI), the Republic of Uzbekistan has transformed into Central Asia's fastest-growing construction epicenter.
Spanning over 20,000 hectares to accommodate 1.5 million citizens, the New Tashkent megaproject demands thousands of concurrent lifting units. Contractors face tight completion windows that brand-new OEM production lines cannot meet due to 6–9 month lead times.
Navoi Mining and Metallurgical Combinat (NMMC) and Almalyk Mining and Metallurgical Complex (AMMC) expansions require high-capacity 10-to-16 ton topkit and flat-top tower cranes for steel mills, leaching tanks, and chemical processing facilities.
Uzbek civil engineering contractors operate on disciplined capital payback cycles. Purchasing inspected late-model Chinese cranes (YOM 2018–2023) reduces equipment investment by 55% to 65% compared to new European imports, maintaining equivalent duty cycles.
Uzbekistan experiences arid continental weather extremes: blistering summer heat exceeding +48°C, freezing winter drops down to -25°C, high airborne sand particulate, and seismic activity classified between MSK-64 Zones 7 to 9. Standard equipment fails without dedicated metallurgical and mechanical adaptation.
Cold-brittle fractures represent a lethal risk when temperatures plummet in Syrdarya or Karakalpakstan. Our pre-export evaluation utilizes Charpy V-notch impact testing data and ultrasonic flaw detection on mast pin holes, chords, and jib joints to verify structural resilience at sub-zero operating regimes.
Tashkent and Samarkand lie in seismically active geological zones. We supply reinforced foundation anchoring stools, customized tie-in collars (wall anchor brackets), and calculate tailored tie-in intervals based on SNiP and KMK 2.01.03-96 construction standards to eliminate harmonic resonance during ground tremors.
Summer desert heat induces thermal degradation in standard hydraulic pumps and electrical contactors. We inspect and retrofit IP55/IP65 sealed control cabinets, install forced industrial dual-cooling systems in hoisting inverters, and verify synthetic ester gear oils rated for high operating viscosities.

Unlike digital brokers or middlemen trading unverified machinery off job sites, Huaian Zhongqiang International Trade Co., Ltd. physically owns, stores, inspects, and reconditions equipment inside our specialized 30-acre engineering staging base in Huai'an, Jiangsu.
Laser-guided coordinate measuring evaluates vertical plumb line deviation, counter-jib camber, and mast squareness to ensure structural straightness within ±1.5mm tolerance.
Critical chord joints, turntable weldments, and jacking climbing cages undergo magnetic particle (MPI) and ultrasonic testing (UT) to detect subsurface metallurgical fatigue.
Hoisting planetary gearboxes are disassembled, bearings swapped with SKF/NSK units, brake lining renewed, and hydraulic jacking pumps pressure-tested to 25 MPa continuous load.
Full surface restoration removes oxidation, followed by zinc-rich epoxy priming and a dual-layer aliphatic polyurethane marine-grade topcoat to protect against Central Asian salt-alkali soils.
Navigating Central Asian landlocked transport requires experienced heavy machinery rigging, precise flat-rack loading plans, customs-compliant documentation, and reliable rail schedules.
Disassembled cranes are loaded into high-cube containers and heavy flat-racks at our yard. Trains depart through Khorgos (Altynkol) or Alashankou (Dostyk), clearing the standard-to-broad gauge bogie transfer and arriving at Tashkent rail terminals (Chukursay Station, station code 720000; Sergeli Station, code 723507) within 12 to 16 calendar days.
We supply full export documentation packages matching Uzbekistan Customs Nomenclature (TN VED code 8426 20 000 0): bilingual Commercial Invoices, Packing Lists with precise section serial numbers, Certificates of Origin (Form A / CO), factory technical passports, and structural load manuals in Russian and English.
Upon train arrival in Uzbekistan, our dispatch team provides detailed 3D step-by-step assembly blueprints, electrical hookup wiring diagrams for 380V/50Hz local utility stability, and can deploy certified erectors to supervise crane climbing and commissioning with local Gosgortekhnadzor state safety inspectors.
Modern lifting operations in congested high-density urban areas like Tashkent City demand intelligent digital retrofits on proven structural airframes.
Where multiple tower cranes operate within overlapping working radii on urban masterplans, we integrate smart wireless anti-collision sensors, real-time slew-angle encoders, and automatic slow-down zone limiters that prevent hook or boom interference.
Keep track of fleet operating hours, motor amperage draws, load cycle counts, and overload trip alarms from a centralized contractor dashboard in Tashkent or overseas headquarters. Preventive maintenance warnings occur before downtime happens.
Modernized VFD frequency converters capture dynamic potential energy during heavy load lowering, feeding clean energy back into local site grids, reducing auxiliary generator diesel fuel burn on off-grid Uzbek industrial zones by up to 22%.
Everything you need to know about payments, railway customs clearance, condition testing, and spare parts supply.
We support Irrevocable Letters of Credit (L/C at sight) opened through reputable international banks, standard T/T bank wire transfers (30% deposit upon contract signing, balance upon container loading and bill of lading issuance), and RMB direct settlements via cross-border interbank payment channels.
Absolutely. Uzbek buyers are welcome to visit our 30+ acre facility in Huai'an, Jiangsu Province. We arrange airport pickup (from Shanghai or Huai'an), host your technical personnel at the yard for test-running hoisting mechanisms, and provide real-time ultra-HD live video inspection for remote auditing.
From our yard, domestic trucking to the international rail terminal takes 2–3 days. Rail transit through Khorgos (Khorgos Gateway / Altynkol) across Kazakhstan to Tashkent typically takes 12–16 calendar days. Total door-to-terminal turnaround is around 20–25 days from departure.
We supply an optional "First-Year Emergency Maintenance Kit" with every export: including contactors, encoders, limit switch assemblies, brake linings, hydraulic sealing gaskets, and mast pins. Moreover, our brands (Zoomlion, SANY, XCMG, Potain) have high component interchangeability across Central Asia.
Yes. We deliver comprehensive factory technical passports, stamped foundation reaction calculation sheets in Russian, original certificates of conformity, electrical schematics, and load test reports that simplify registration with Uzbekistan's state industrial safety authorities.
Our in-house heavy machinery lashing team applies anti-collision wooden blocks, high-tensile steel banding, and industrial waterproof shrink-wrap to sensitive slewing raceways, electric motors, and the operator's air-conditioned cab. Open-top containers and flat-racks follow strict international railway tie-down standards.
From 10-to-12 ton flat-top and hammerhead cranes to high-speed passenger/material hoists (SC200/200), all available directly from our export staging yard.
