Frequently Asked Questions

Six inputs cover most projects: lifting capacity (t), span (m), lifting height (m), duty (lifts per hour, hours per day), power supply (voltage / frequency) and the working environment (indoor or outdoor, dust, temperature). Building drawings or photos help a lot.

Rule of thumb: a single girder crane is lighter and more economical and covers most workshop jobs at moderate capacity, span and duty. A double girder crane wins for heavier capacities, wider spans, harder duty cycles and when you need maximum hook height.

Duty class describes how hard the crane works — load spectrum times operating time — from light workshop duty up to continuous steel-mill duty. Getting it right protects both lifetime and price: over-specifying costs money, under-specifying costs the crane.

Full answer: Selection of ISO Standard for Crane Working Class →

Capacity = your heaviest regular load plus the weight of any below-the-hook device (magnet, grab, spreader) plus a sensible margin — don't size the whole crane for a once-a-year lift. Span = the distance between runway rail centers, normally your column spacing minus clearance. Lifting height = floor to highest hook position — watch the roof trusses.

Our engineers check all three free of charge; the wheel load calculator then gives your building designer the runway loads.

Yes — customization is our normal mode of work: non-standard spans, low-headroom designs, outdoor duty, magnets, grabs and other below-the-hook devices, and special cranes for steel mills, scrap yards, paper mills and shipyards.

The honest answer: it depends on five factors — capacity & span, duty class, component brands, certification requirements and trade terms. As a rough indication for standard configurations: a 5 t single girder overhead crane typically falls around US$6,000–15,000 FOB, a 10 t single girder around US$9,000–20,000, a 20 t double girder around US$25,000–60,000; heavy-duty and special cranes are quoted per project.

Your exact price arrives itemized within 24 hours — see what to include in your inquiry.

Four usual reasons: steel quantity (girder plate thickness varies enormously between designs), duty-class honesty (a crane quoted as A5 but built as A3 is cheaper — until it wears out), component brands (hoist, motors, electrics), and what's included (freight, certification, spares, support). Ask every supplier for an itemized quote and compare line by line — ours comes itemized by default. Be cautious with a price far below the pack: the steel alone has a market price.

A recommended configuration and budget price within 24 hours of receiving capacity, span and lifting height. Formal quotations stay valid for 30 days; steel prices and exchange rates move, so after that we reconfirm — usually the same day.

Most orders run T/T: a deposit with the order, balance before shipment — goods ship once the balance clears. Irrevocable L/C at sight is accepted, though we'll tell you honestly: L/C means higher bank fees and slower payment, and many buyers get the same security for less with T/T plus SGS pre-shipment inspection. Smaller orders can simply pay in full by T/T. A proforma invoice states the exact terms before you pay anything.

One crane is a normal order — no minimum; we even take spare-parts-only orders. We quote EXW, FOB, CIF or CFR routinely, and DAP / DDP for many destinations (recent DDP deliveries include Mexico and Malaysia) — availability confirmed per destination country. Send your port and we'll include freight so you compare true landed cost, not just factory price.

A manufacturer. Henan Kino Cranes has built overhead and gantry cranes for 18+ years on a production base of about 150,000 m², with 500+ production and testing machines, 500+ employees, a dedicated R&D center and an annual capacity of 3,000 cranes — 5,000+ projects delivered to 120+ countries. And you don't have to take our word for it: visit the factory, take a live video tour, or send an inspector.

See the production system: Quality & Certification →

Yes, and we encourage it. Book a visit 3–5 working days ahead; we assist with the invitation letter (allow about a week for issue) and arrange reception locally. Can't travel? A live video tour walks you through the production lines and your own order in progress — several recent orders, Indonesia among them, were verified entirely by video tour plus regular production updates.

Preview first: factory & product videos →

Yes — and we often recommend it: SGS, BV, TÜV or any inspector you appoint, for pre-shipment inspection or loading supervision. The fee (typically a few hundred US dollars) is borne by the buyer, and for many orders T/T plus SGS inspection replaces a costly L/C outright. Agree the agency, scope and timing with us before ordering so testing slots into the production schedule.

Very likely — 5,000+ projects across 120+ countries: the Middle East, Southeast Asia, South America, Africa and Europe. Tell us your country and application and we'll share reference cases like yours, with client details anonymized.

Typical production time: 4–6 weeks for standard single girder cranes, 8–10 weeks for double girder; complex custom cranes are scheduled per project — large metallurgical systems can run several months. Add sea freight for door-to-door planning. The schedule is written into the contract and tracked with progress updates.

As standard, you receive test photos and videos before packing — proof of your crane running, on record before it ships. For major orders we provide regular progress updates through production, and a live video call at any point is fine. You don't need to fly here to know exactly where your crane is.

Every crane passes our five-gate QC and a final test sequence: no-load running of every motion and powered function tests of all mechanisms and limit switches — with photos and videos sent to you before packing. Need a witnessed load test? It can be arranged — in person, by your third-party inspector or on video; scope and cost are agreed before production starts.

The full system: 5-Step Quality Control →

Three ways: come and witness the load test in person, appoint a third-party inspector, or join by live video — we run the full test on camera and send you the recording either way.

High-strength steel wire rope matched to the hoist capacity and duty class by the design standard — the exact construction and diameter are stated on your crane's GA drawing and spare-parts list.

Full answer: What Type of Wire Rope is Used on Crane? →

Three standard options, freely combinable: pendant pushbutton (economical), radio remote (most popular — the operator moves freely), and cabin control for heavy or continuous duty. Variable-frequency drives give smooth acceleration in all cases.

Full answer: How Many Control Methods Does Bridge Crane Have? →

We build to your grid: 380V/415V at 50Hz, 440–460V at 60Hz and other national standards, with control circuits at safe low voltage (36/48V). State voltage and frequency in your inquiry — it affects motors, panels and certification.

Rail gauge, straightness and level tolerances decide how smoothly the crane runs — and how fast wheels wear. Rail clamps must be installed to procedure before the crane goes up.

Three working modes: your team installs with our documentation plus live video guidance — free of charge, with mechanical and electrical engineers on the call (most common); we dispatch an engineer on a per-day basis with travel, lodging and visa borne by the buyer (rates quoted per project); or we coordinate with a local rigging company you hire. We recommend the right mode with your quotation.

Typical port-to-port times from China: Southeast Asia 7–15 days, Middle East 15–25, Europe 28–40, Africa 20–45, South America 35–50 — season and routing move these. For CIF/DAP orders we book the vessel and share the schedule as soon as space is confirmed.

5,000+ projects delivered to 120+ countries — the Middle East, Southeast Asia, South America, Africa and Europe. Send your destination port and we quote FOB, CIF or DAP as you prefer.

Girders beyond 40' container length ship on open-top or flat-rack containers, or as break-bulk cargo on conventional vessels — carried on engineered transport saddles with a lashing plan. Routine for us: spans over 30 m travel this way.

Count cases against the packing list before signing, photograph any external damage, and open-check within 7 days with written feedback against the packing list. If anything is missing or damaged, send photos — the container photos taken before closing establish responsibility fast, and replacements ship immediately (urgent missing items go by air; it's an established process, not a favor).

Same three modes as installation support: your team with our documents + live video guidance, our engineer on site, or a local rigging company we coordinate with. The most efficient pattern, proven across projects: your team completes mechanical installation, wiring and foundations, then our engineer arrives for commissioning — days on site instead of weeks.

The standard sequence: no-load runs of every motion, then a rated-load test, checking deflection, speeds, brakes and limit switches against the acceptance sheet supplied with the crane. Where your local regulations require a witnessed overload test, we support it — agree the scope with us and your inspector in advance. Pass, sign, lift.

Standard warranty is 12 months from commissioning completion, capped at 18 months from the B/L date — stated in your contract, covering manufacturing defects in structure and components. During warranty we resolve issues by remote diagnosis, replacement parts or, where needed, an engineer visit — and wear parts stay available long after.

Send the crane number from the nameplate plus a photo of the part — common wear parts (contactors, brake pads, wheels, ropes) dispatch within 3–7 days from stock or production, and urgent warranty parts go by air. A recommended spares kit can ship with the crane.

Daily operator checks (hooks, ropes, brakes, limit switches) plus scheduled periodic inspections — and whatever statutory intervals your local regulations impose. Our checklist is a solid baseline.

Full answer: Overhead Crane Inspection Checklist →

Send the crane number from the nameplate plus photos or a video of the fault — our engineers respond within 24 hours, remote diagnosis first, and most issues are identified the same day. The usual fix is a part from stock with video-guided replacement; anything bigger, we arrange an engineer visit.
