Промышленный кран Глоссарий

Кран Types

Мостовой кран (Bridge Crane)

A crane with a horizontal bridge spanning two parallel runways, used for lifting and moving heavy loads inside a workshop. Емкость обычно 0.5T-150T (some up to 500T). Single-girder or double-girder configurations. Chinese model designations: LD (single-girder), LH (double-girder hoist trolley), QD (double-girder universal), YZ (metallurgical).

Козловой кран

A crane structure supported on legs that run on rails at ground level, used outdoors at ports, shipyards, precast concrete plants, or wherever no overhead runway exists. Models: MH (electric hoist single-girder), MG (double-girder), MGH (double-trolley), RTG (rubber-tyred for container terminals), RMG (rail-mounted for container terminals).

Jib Кран

A slewing crane with a horizontal jib (arm) supported from a vertical column, wall, or pillar. Used for localized lifting (e.g. machine-tool loading, welding workstations). Slewing range: 180° (wall-mounted) or 360° (pillar / floor-mounted). Емкость обычно 0.25T-10T.

Electric Hoist

A self-contained lifting единица with motor, gearbox, drum, brake and pendant or radio control, used as the lifting element on cranes or stand-alone on a monorail. CD1 / MD1 (Chinese GB/T 6067 standard wire-rope hoists, 0.5T-30T), DHP / DHK (electric chain hoists, 0.25T-5T).

KBK Кран (Light Rail Crane)

A modular light-duty crane system with cold-rolled steel sections, suspended from the ceiling. Used for repetitive light-load lifting in assembly lines. Емкость 0.125T-2T. Originally developed by Demag — Chinese KBK-equivalents are widely produced in Hefei.

Smart Mechanical Parking System

An automated multi-storey car parking structure using motor-driven lifts and shuttles to stack vehicles. Категории defined by GB/T 17907: PSH (puzzle-stack lift-slide), PCS (chain-circulation), PCX (rotary tower), PPYL (vertical-lift), PJS (plane-mobile). Chunhua supplies PSH 2-5 levels and PCX towers up to 25 levels.

Manipulator (Industrial)

A balanced articulating-arm lifting device for high-frequency, precision-placement tasks (auto assembly, glass handling, drum tipping). Typically pneumatic-balanced or electric-servo. Емкость 50kg-300kg. Replaces hand-lift operations where load is repetitive.

Components & Электрический

Wheel Block

A pre-engineered crane wheel-and-housing assembly combining wheel, bearings, end-stop and motor mount. Demag, ABUS, SWF and Chinese equivalents (KEY, Henan-style) standard sizes 125/160/200/250/315/400mm. Eliminates field machining.

VFD (Variable Frequency Drive)

An inverter that controls motor speed by varying supply frequency. Standard on modern cranes for smooth start-stop, anti-sway operation, and energy savings. Common brands: Schneider Altivar (ATV320/340), Siemens Sinamics G120, Yaskawa A1000, Chint NVF600. Specify VFD on order to avoid contactor-control retrofit.

FEM Duty Class

European crane classification per FEM 1.001 / ISO 4301-1 based on load spectrum and number of working cycles. Common classes: M3 (light/intermittent), M5 (medium), M6 (heavy), M7 (very heavy continuous), M8 (continuous severe — used for steel mill ladle cranes). Higher class = heavier-spec gearbox, brakes, bearings, structural steel.

GB/T 3811

Chinese national crane design code — equivalent to ISO 8686 / FEM 1.001 framework. Defines duty groups A1-A8 (similar to FEM M1-M8), load combinations, stress factors. Chinese cranes are baseline-designed to GB/T 3811; FEM/DIN/CMAA verification is an upgrade at quote stage.

Q345B / Q235B Steel

Chinese structural steel grades per GB/T 700 / GB/T 1591. Q235B ≈ EN S235JR (yield 235 MPa). Q345B ≈ EN S355JR (yield 345 MPa). Кран main girders обычно Q345B for capacity ≥10T; Q235B for end carriages and walkways. Chemistry meets EN 10025-2 for CE-marked exports.

Slewing Bearing

A large-diameter rolling bearing supporting the rotating column of a jib/tower crane or RMG. Typical types: ball single-row four-point contact, ball double-row, or roller three-row. Manufacturer spec: external/internal gear, raceway hardness ≥55 HRC.

Trolley

The movable cross-runway carriage that carries the lifting hoist on a bridge or gantry crane. Open winch trolley (separate motor + drum, on double-girder) or compact electric-hoist trolley (single-girder LH/MH).

Отгрузка & Incoterms

FOB (Free On Board)

Incoterm: seller delivers goods on board the vessel at named port of shipment. Buyer takes risk and cost from that point. FOB Shanghai / Ningbo / Tianjin is our default quote basis. Buyer arranges sea freight, marine insurance, destination customs.

CFR (Cost and Freight)

Incoterm: seller pays cost and sea freight to named destination port. Risk transfers when goods are on board at origin. Most popular Incoterm for African / Ближний Восток crane buyers — seller handles ocean booking; buyer handles insurance and destination clearance.

CIF (Cost, Insurance and Freight)

CFR + minimum-value marine insurance arranged by seller. Chunhua Кран Export upgrades to 110% CIF value cover with All Risks + War Risk clause via PICC Китай. Standard for European, Русский (when port-deliverable), and tender shipments.

DDP (Delivered Duty Paid)

Incoterm: seller delivers to named place at destination country with all import duties, taxes and customs cleared. Used for US / EU buyers under 40ft container — eliminates buyer customs hassle but adds 8-15% to project cost. Not commonly offered to LatAm (customs complexity).

Out-of-Gauge (OOG) Cargo

Cargo exceeding standard 40ft container dimensions (length 12.03m / width 2.35m / height 2.39m). Large gantry crane main beams (>12m span) ship as OOG навалочный on flat racks. Sea freight cost ~20-40% higher than container.

L/C at Sight

Letter of Credit payable upon presentation of compliant shipping documents. Buyer's bank guarantees payment; reduces seller risk on first-time buyers. Chunhua Кран Export accepts L/C ≥ USD 50,000 advised by major banks (Bank of Китай / ICBC / HSBC / Standard Chartered).
