The client is a light industrial manufacturer in Bangladesh and needed an indoor lifting solution for their workshop floor. They requested 5-ton HD single-girder overhead cranes with integrated steel runway beams to support daily material handling. The site required a span of 5 meters and a lifting height of 4.1 meters, which fit well within the existing building structure. The customer preferred a hard-wired push-button pendant control for simple and reliable operation on the shop floor. For the lifting mechanism, they selected a Euro-style NR wire-rope hoist from the NR/ND series to ensure smooth lifting, precise control, and long service life. This configuration provides a compact, cost-effective, and efficient overhead crane system for light industrial indoor applications. They also wanted a steel runway integrated into the building structure so the crane could be used immediately without costly structural upgrades.
The Client's Core Lifting Need
The customer's core lifting need was a compact and reliable 5-ton overhead crane for an indoor facility with limited headroom. They required a system that fits a low-clearance building, integrates with a steel runway, and supports frequent small to medium lifts during daily production. Maximizing hook height while minimizing crane headroom and runway load was a key goal. The customer focused on uptime, stable performance, and predictable operating costs rather than advanced automation. They also wanted equipment that local technicians could maintain easily, with readily available spare parts and short service lead times. Based on these priorities, we selected a low-headroom wire-rope hoist, a single-girder bridge design, and standard electrical and mechanical components to deliver a practical, durable, and easy-to-maintain lifting solution.
Our lifting solution
1. Crane type and model
We delivered a Yuantai top-running single-girder HD overhead crane with a 5-ton rated capacity and an under-slung Euro NR trolley in a low/standard headroom configuration. This layout keeps the hook closer to the working level while minimizing the runway and building modifications you need. For a 5-metre span and 5-ton load, the single-girder approach reduces the crane's dead weight and the loads transferred to the runway. That makes installation faster and lowers civil costs. The girder and endcarriages were sized for the rated wheel loads and for routine inspection access. We also factored in common workshop needs like safe walking clearance, simple maintenance access, and a sensible service factor so the crane is reliable under frequent cycles.
2. Hoist selection — Euro NR wire-rope hoist
We paired the crane with a Euro NR electric wire-rope hoist sized for your 5-ton single-hook requirement and set the lift to the customer's 4.1-metre height. The NR family gives a compact footprint useful for low headroom spaces, while the drum and rope design offers a long service life under high cycle counts. We chose a two-speed lift arrangement so lifts can be both efficient and precise where needed. The hoist uses an electromagnetic disc brake with a fail-safe design and includes the usual protective features you expect on modern hoists, such as overload detection and thermal protection. The overall selection aims to give you a robust, easy-to-service hoist that runs smoothly in a workshop setting.
3. Control and operator interface
Primary control is a hard-wired pendant push-button station served by a festoon or cable droop system depending on the final layout. Pendants are straightforward and extremely reliable indoors, so you avoid radio battery issues and possible RF interference. The pendant gives the operator clear, repeatable control right at the load. If you need more mobility, we can fit a radio remote. For smoother starts, finer positioning, and energy savings, we can add VFDs for hoist and travel motors. Safety items such as upper and lower limit switches, emergency stop, and an electronic overload limiter were included or offered as options so you keep predictable, safe control over lifts.
4. Steel structure & runway
We supplied a matched steel runway system with rolled beams sized for the crane's static and dynamic wheel loads and for the live loads shown in the buyer's site data. The runway uses bolted splice connections and stiffener plates so on-site assembly is straightforward and fast. Anchor bolt layouts were prepared to suit the concrete capacity at the site, and the structural design was checked against local seismic and loading conditions. For export to Bangladesh we also recommended appropriate surface treatment and corrosion protection to suit humid coastal environments. The result is a runway and support structure built to work with the crane and to simplify installation, inspection, and future maintenance.
Design details & engineering decisions
We focused on practical choices that deliver safe, reliable performance while fitting customer's site constraints. Each decision balanced lift capability, long-term durability, and user needs. We documented assumptions so the customer can see why parts were sized the way they were.
1. Headroom optimization and lifting height
The site had tight vertical clearance, so we chose a Euro NR low-headroom trolley to get more hook travel inside the same building space. This hoist layout uses a compact trolley and a larger drum diameter so the hook sits higher when the rope is fully wound. That approach gives you the specified 4.1 m of usable hook travel without cutting into the building roof or changing structural members. We also checked drum layers, rope lead and reeving to ensure the full lift meets capacity and fatigue expectations over time.
2. Duty classification & safety factors
We picked a duty class in line with ISO 4301-1 to match the expected cycles and the load pattern at your plant. Choosing a mid-range class (for example A4/A5 for light industrial continuous use) drives how large we make bearings, gears, and ropes and sets the fatigue life targets. All choices were recorded and shared so the customer can trace why each component was specified. During commissioning we ran standard static proof and functional tests, and we built in the safety margins required by the applicable standards.
3. Positioning, motion control and optional VFDs
We recommended VFDs as an option because they smooth starts and stops and help you position loads more precisely. That reduces mechanical shock and can lower peak electrical demand during duty cycles that need fine control. For this project, pendant control with conventional starters met the reliability needs and the budget. If the customer later need finer positioning or softer handling, a VFD retrofit or factory-fitted drives are straightforward to add.
4. Electrical & mechanical components
We selected AC motors sized to the crane's duty and fitted thermal protection to guard against overheating. The hoist drum, gearbox and wire rope follow the NR hoist family standards so performance and spare-parts logic stay consistent. Cable festooning or drag-chain systems were sized to the span and travel to avoid premature wear. We included essential safety devices such as limit switches, anti-two-block, overload protection and accessible emergency stops to meet regulatory and operational expectations.
5. Corrosion, paint & local environment
Even though the crane is installed indoors, we specified a protective coating system matched to local humidity and seasonal conditions in Bangladesh. For sites with higher humidity or coastal influence we recommend stronger coatings and stainless or galvanized fasteners to reduce corrosion risk and maintenance needs. We noted these options in the project records so the customer can choose the level of protection that best fits your expected service life and maintenance plan.

Implementation & Project Management
This project required careful coordination to meet the customer's schedule and site conditions. We focused on clear communication, early risk checks, and parallel production to reduce delivery time. Our goal was to make the installation smooth and avoid delays that often happen in overseas crane projects. By managing design, fabrication, logistics, and site work as one integrated process, we ensured the 5-ton HD overhead crane system was delivered and installed with minimal disruption to the customer's operations.
1. Project Management
A dedicated project manager acted as customer's single point of contact throughout the project. This made communication simple and efficient, from design approvals to shipping updates and on-site coordination. Before fabrication, we conducted a pre-installation survey to confirm the building structure and concrete foundations could safely support the crane system. This step helped prevent costly changes later. At the same time, we prepared the hoist and trolley assemblies in parallel with runway fabrication. This approach shortened the overall project timeline and helped the customer start using the crane sooner.
2. On-Site Challenges & Solutions
The site had limited access for large crane components, so we delivered the bridge girder in modular sections with bolted connections. This reduced the need for heavy lifting equipment on site and made installation safer and faster. The customer also had concerns about unstable power quality, which can damage electrical components. We addressed this by adding input protection and soft-start features, and we specified line reactors and surge protection when VFDs were used. In addition, the building had tight roof height, but the customer still needed full hook travel. We solved this with a low-headroom NR trolley and optimized beam design, which provided the required lifting height without changing the building structure.
3. Safety Checks and Acceptance
During installation and commissioning, we carried out full functional tests to ensure every motion worked smoothly. We performed static load tests at 125% of the rated capacity and dynamic tests for hoist, trolley, and bridge travel. All safety devices, including limit switches, emergency stops, and overload protection, were checked carefully. We also provided operator training and complete handover documents so you can run the crane safely and efficiently. The customer's appointed engineer reviewed and signed off all test results, confirming the system met project and safety requirements.
Maintenance, spare parts & after-sales support
A reliable crane depends on proper care, timely parts replacement, and strong technical support. A clear maintenance plan helps you avoid unexpected breakdowns and costly downtime. Spare parts on hand keep the customer's operations running smoothly when something wears out. Strong after-sales service also gives the customer confidence that help is available when you need it. Below is a practical maintenance schedule, a recommended spare parts package, and clear warranty and service options.
1. Preventive Maintenance Plan
A preventive maintenance plan helps you extend the crane's service life and maintain safe operation. Daily checks should focus on visual inspection, wire-rope condition, and proper function of limit switches and the emergency stop system. Monthly tasks should include lubricating moving parts, checking brake performance, and inspecting the festoon system or power cables for damage. Quarterly inspections should cover gearbox oil levels, motor brushes or commutators if applicable, and the condition of wheels and bearings. An annual inspection by a certified technician is essential. This should include a full safety check, a review of rope replacement intervals, non-destructive testing of critical welds, and a load test if required by local regulations. This schedule helps the customer reduce risks and plan maintenance in advance.
2. Spare parts package
We recommend a basic spare parts kit to minimize downtime and keep the customer's crane running without long delays. This kit includes one spare brake assembly to address braking issues quickly. It also includes rope clips and a replacement wire rope with sufficient length for a 4.1 m lift plus drum allowances. A spare contactor set and overload relay are included to handle electrical failures. A set of wheel bearings is also provided to support fast replacement of wear parts. Keeping these parts on site helps the customer respond to issues immediately and avoid waiting for international shipments.
3. Service & warranty
The crane comes with a standard 12-month warranty from the commissioning date. This covers parts and labor according to the agreed terms. The customer can also choose extended service options, such as annual preventive maintenance contracts and remote troubleshooting support. These services help the customer keep the crane in good condition and reduce operational risks.
