A Buyer’s Guide from DONGQI CRANE for Comparing Proposals and Avoiding Costly Oversights
You have requested quotations for an overhead crane. Three suppliers have responded. The prices vary by 40%, and the technical descriptions look similar—but are they? One proposal is three pages of dense specifications. Another is a single paragraph with a price. How do you know what you are actually buying?
Reading a crane quotation is not like comparing prices on a standard commodity. A crane is an engineered system. Two “10-ton overhead cranes” can differ in ways that affect performance, safety, maintenance costs, and total service life. The quotation document is your only window into what the supplier intends to build and deliver. Missing a critical detail at this stage can lock in a decade of operational headaches.
At DONGQI CRANE, a Sino-New Zealand joint venture with over 40 years of manufacturing experience and products operating in 96 countries, we have seen buyers accept quotes that looked complete but concealed costly omissions. This guide identifies the 10 configuration details you must verify before comparing prices or signing a contract. Use it as a checklist when reviewing any crane quotation.
Crane suppliers structure quotations differently. Some provide a single lump-sum price. Others break out equipment, freight, installation, and certification as separate line items. Some list every component by brand and model number. Others use generic descriptions like “quality gearmotor” or “standard electrical panel.”
The most common tactics that create misleading price comparisons:
The solution: Do not compare prices until you have verified that the configurations are identical. The following 10-point checklist ensures you are comparing apples to apples.
Why this matters more than any other specification:
Work duty classification determines how hard and how often the crane can work without premature failure. It is the single most important variable affecting both price and lifespan. An A3 crane costs 30–46% less than an A7 crane of the same capacity—but will fail within months if operated in a continuous production environment.
What to look for in the quotation:
Red flags:
How DONGQI CRANE addresses this: Every DONGQI CRANE quotation includes an explicit FEM/ISO work duty classification based on our engineering analysis of your application. We document the load spectrum, daily operating hours, and design life assumptions so you understand exactly what you are purchasing.
Why this matters:
A discrepancy of even 100mm in span measurement can cause wheel flange wear, derailment risk, or the crane simply not fitting on the runway. Lift height miscalculations can mean the hook cannot reach the floor—or cannot achieve the clearance required for your tallest loads.
What to look for in the quotation:
Red flags:
How DONGQI CRANE addresses this: Our quotation process requires confirmed span and lift height measurements. If you cannot provide them, we will guide you through measuring correctly. For complex installations, we review building drawings and provide a clearance verification drawing before finalizing the proposal.
Why this matters:
The electric hoist generates the lifting force. Its quality determines reliability, maintenance frequency, and spare parts availability. A quotation that says only “wire rope hoist” without specifying brand and model conceals one of the largest cost and quality variables in the entire system.
What to look for in the quotation:
Red flags:
How DONGQI CRANE addresses this: Every DONGQI CRANE quotation specifies the exact hoist model, motor brand, lifting speeds, and work duty classification. We offer CD type (single-speed), MD type (dual-speed), and European-style hoists with premium SEW/NORD components. You know exactly what you are paying for.
Why this matters:
The electrical panel is the brain of the crane. The quality of contactors, relays, VFDs, and circuit protection determines operational reliability and safety. Generic electrical components fail more frequently, are harder to troubleshoot, and may not meet local electrical code requirements.
What to look for in the quotation:
Red flags:
How DONGQI CRANE addresses this: Our quotations list the brand and model of major electrical components. We partner with Schneider Electric, Siemens, and ABB to ensure global availability of replacement parts and consistent quality. Every quote includes enclosure protection ratings appropriate for your operating environment.
Why this matters:
The crane’s steel structure must withstand years of cyclic loading without fatigue failure. The quality of steel plate, welding procedures, and surface treatment directly affects structural integrity and corrosion resistance—especially in coastal, high-humidity, or chemical environments.
What to look for in the quotation:
Red flags:
How DONGQI CRANE addresses this: Our quotations specify steel grades, welding procedure qualifications, and surface treatment standards. We offer standard industrial paint systems and optional C5-M marine-grade coatings for demanding environments. Material test certificates and weld documentation are included in every shipment.
Why this matters:
Safety features are not optional extras—they are essential systems that protect operators, equipment, and your facility. Some suppliers quote bare-minimum configurations and treat safety devices as “add-ons” that increase the final price after you are committed.
What to look for in the quotation:
Red flags:
How DONGQI CRANE addresses this: Every DONGQI CRANE quotation includes a complete safety system as standard: overload protection, limit switches on all motions, emergency stop, and audible/visual warnings. We do not treat safety as an optional upgrade.
Why this matters:
A crane sitting on your factory floor in parts is not an operational asset. Installation, commissioning, and load testing represent 25–50% of the total project cost. Some quotations exclude these items entirely, creating an artificially low equipment price while leaving you responsible for a complex, safety-critical installation.
What to look for in the quotation:
Red flags:
How DONGQI CRANE addresses this: We provide clear options for installation support. DONGQI CRANE dispatches experienced engineers directly from our China headquarters to your facility anywhere in the world. Our engineers supervise installation, oversee commissioning, and conduct certified load testing. You receive support from the engineers who designed and built your crane—not third-party contractors.
Why this matters:
Freight costs for heavy, oversized crane components can equal 5–20% of the equipment price. Delivery timelines affect your project schedule. A quotation that omits freight costs or provides unrealistic delivery promises creates budget and schedule risk.
What to look for in the quotation:
Red flags:
How DONGQI CRANE addresses this: Every quotation specifies the Incoterm, estimated production lead time, and shipping transit expectations. For CIF or DAP quotations, freight and insurance are included. Our export logistics team manages documentation and coordinates with freight forwarders to ensure smooth customs clearance.
Why this matters:
Warranty terms define your recourse if the crane fails prematurely. After-sales support determines how quickly you can recover from downtime. Vague warranty language and unclear support processes are red flags that can leave you stranded when problems arise.
What to look for in the quotation:
Red flags:
How DONGQI CRANE addresses this: Our quotations include clear warranty terms and a defined claims process. DONGQI CRANE does not maintain local agencies or spare parts warehouses in destination countries. Instead, we provide direct-from-factory support: spare parts ship within 24–48 hours via international express courier, reaching most global destinations within 3–7 business days. Remote technical support is available via WeChat, WhatsApp, or Zoom. For complex issues, we dispatch engineers directly from our China headquarters.
Why this matters:
A crane cannot be legally operated without proper certification. Customs clearance, local regulatory approval, and insurance coverage all depend on complete, accurate documentation. A quotation that does not address certification requirements may leave you with a crane you cannot use.
