In 2026, Kinocranes supplied four 5 Ton European standard Double Girder Overhead Crane units to a steel processing plant in the United Arab Emirates. All four share the same 18.95 m span and 7 m lifting height, and all four were installed in the same workshop. The interesting number here is not the tonnage — it is the span, and the fact that there are four of them.
The client processes steel: plate and section are cut, fabricated and moved across a long workshop, and material spends most of its time in the air between workstations rather than sitting on the floor. That pattern is what drives the specification. Capacity is modest at 5 tonnes, because a single plate or bundle is not especially heavy; span is large, because the crane has to reach across the full working width of the bay; and there are four of them, because several workstations need coverage at the same time without cranes queuing behind each other.
The customer did not order one crane and then repeat it. Four machines to the same 18.95 m span were built, shipped and commissioned together, so the workshop runs one spare parts list, one maintenance procedure and one set of operator training — not four.
Kinocranes was asked to quote quickly against the customer’s own building layout, and the layout was still moving while the quotation was being prepared. Parameters were adjusted and the solution re-issued more than once before the drawings were frozen. The delivery programme was tight and had to be held against the construction schedule of the workshop itself.
The delivered 5 Ton European Double Girder Overhead Cranes feature the following key specifications. These parameters define the working envelope for steel handling across a wide bay and provide a clear basis for equipment inspection and operation:
| Model | KD ST-18.95m H7 M5 Double Girder Hoist |
| Crane Type | European Standard Double Girder Overhead Crane |
| Capacity | 5 T |
| Span | 18.95 m |
| Lifting Height | 7 m |
| Working Duty Class | M5 |
| Quantity | 4 sets |
| Hoisting Speed | 5 / 0.8 m/min (dual speed) |
| Trolley Travel Speed | 0–20 m/min (variable frequency) |
| Crane Travel Speed | 0–32 m/min (variable frequency) |
| Power Supply | 400V / 50Hz / 3 Phase |
| Control Voltage | 48 V |
| Motor Type | European standard motor |
| Control Method | Pendant control + push button remote control |
| Working Environment | Indoor, steel processing workshop |
A long span on a light load is the harder combination. Deflection, not strength, governs the girder, so the box sections were sized for stiffness across nearly nineteen metres rather than for the rated tonnage. This is where a European double girder design earns its cost over a heavier conventional build.
Every crane in the bay is dimensionally identical. Spares are interchangeable between them, a fault on one can be diagnosed against three working references, and the commissioning team proved one machine then repeated it three times instead of solving four separate problems.
The slow speed exists for one reason: setting a load down accurately. In steel processing the last few centimetres of a lift decide whether plate lands where the operator wants it, and 0.8 m/min is the difference between placing and dropping.
Trolley travel 0–20 m/min and crane travel 0–32 m/min, both under VFD control. Smooth acceleration matters more than top speed when the load is long steel section that will swing if it is started or stopped sharply.
Control circuits run at extra-low voltage rather than mains. It is a small cost at the build stage and the correct default for a workshop where operators handle pendant controls all day.
The cranes went in while the steel hall was still being finished, lifted onto their runways by mobile crane through the open structure. Once a building of this type is clad there is no way to introduce a nineteen-metre girder, so crane and building programmes had to be planned against each other.
The cranes were lifted onto their runways by mobile crane while the workshop steelwork was still open, then aligned and commissioned in sequence. Kinocranes provided technical support on runway and installation questions during this phase and sent experienced engineers to guide the work on site. Runway tolerance is the item that decides whether a long-span crane runs well or fights its rails for the rest of its life, so it is worth resolving before the first machine is landed rather than after.
Every Kinocranes crane is pre-assembled and load tested at the factory before shipment, so that fit and function are confirmed in our own workshop rather than on the customer’s site. For a repeat build this matters more than usual: the four machines were checked against the same agreed 5 T capacity, 18.95 m span, 7 m lifting height, M5 duty group, 400 V / 50 Hz / 3-phase supply with 48 V control circuit, and the same dual-speed hoisting and variable frequency travel arrangement, so that what arrived on site was genuinely four of the same crane.
Kinocranes supplies full-series crane products with professional engineering support, timely customer service and cost-effective prices. For this UAE project we completed fast quotation turnaround against a moving building layout, repeated parameter adjustment and re-issue of the solution, production of four identical machines to a compressed schedule, pre-assembly and load testing, shipment, and on-site installation guidance.
