A Zambian warehouse operator needed a durable, budget-friendly lifting solution for on-both-sides overhead handling. We initially proposed a 10-ton Euro single girder overhead travelling crane, but due to the customer's budgetary constraints, we finally delivered a lower-cost, economical 10-ton LD single girder overhead travelling crane equipped with a CD-type electric wire rope hoist (working class M3). The LD + CD combination delivered safe, reliable lifting for daily material handling, reduced installation costs, and preserved long-term uptime with straightforward maintenance.well.

What the Customer Needed — Crane Requirements

The customer's operational needs were simple but important:

• Capacity and frequency: Repeated lifts up to 10 metric tons across the warehouse.
• Two-side installation: A crane on both sides of the building to create overlapping working zones and faster load handling.
• Durability and uptime: Equipment had to be rugged for daily industrial use and require minimal downtime.
• Budget sensitivity: The customer asked for a solution that cut capital outlay while retaining essential safety and performance.

The customer's priority was to streamline warehouse handling efficiency without overcomplicating the infrastructure. Their facility layout called for flexible material movement across two working zones, and any downtime in lifting operations would directly impact productivity. Safety was equally important—both for operators and for the integrity of the loads being transported—so the solution needed to combine reliable lifting performance with user-friendly controls. Moreover, since the warehouse operated on a tight budget cycle, the customer sought a cost-effective crane system that could deliver long-term value, reduce maintenance costs, and avoid expensive over-specification. In short, the challenge was to design a practical yet dependable overhead crane solution that balanced performance, safety, and affordability.

How the Overhead Crane We Provided Can Solve Various Tasks

The 10 Ton LD Single Girder Overhead Travelling Crane combined with a CD electric hoist proved to be the ideal combination of dependability, performance, and affordability when the customer needed an effective lifting solution for their busy warehouse. The LD model offers smaller dimensions, lower structural loads on the building, and simpler integration into existing facilities in contrast to bigger double girder systems. While controlling long-term operating and maintenance expenses, it successfully handled a variety of difficult duties, from repetitive heavy lifting to erratic load handling, despite its fairly straightforward design. I describe how the crane effectively addressed the particular operational issues raised by the customer below.

1. Handling Repeated Heavy Lifts and Cycle Demands

Moving big pallets, welded steel assemblies, and packed items from one workstation to another was necessary for the customer's everyday operations. With its smooth, controlled lifting and traversing that reduced load swing and increased safety while lowering the possibility of damaging delicate components, the 10-ton LD crane met the task. Its working class M3 CD hoist was well suited to the modest duty cycles required; it could start and stop frequently without overheating or wearing out too quickly. In order to balance operator safety and productivity, lifting and travel speeds were adjusted to the process. The LD crane reduced rework from improperly handled goods, streamlined operations, and guaranteed constant output in a high-demand production setting by offering reliable handling of large things.

2. Reduce Congestion on the Shop Floor

Congestion in the warehouse's workflow was one of the main issues for the customer. The facility acquired a material handling solution that functioned completely overhead without taking up valuable ground space by implementing bridge cranes mounted on steel structures along both sides of the building. By removing obstacles from the floor and enabling operators to transport large loads directly above work areas, this design avoided traffic jams and decreased the possibility of accidents brought on by clogged roads. The cranes provide smooth coverage for lifting and moving items between different areas of the warehouse, while the overhead system established orderly, unobstructed ground routes for workers and mobile equipment. Workflow improved as a result, becoming safer, more efficient, and able to sustain larger throughput without necessitating an expensive expansion of the building's footprint.

3. Rigidity Under Irregular Loads and Simple Maintenance Requirements

Unpredictable loading situations, such as shifting, asymmetrical, or off-center loads, are common in warehouses. Even in situations where the load location wasn't ideal, the LD single girder crane's torsional rigidity was designed to withstand such situations up to its 10-ton rated capacity, guaranteeing safe and predictable operations. With fewer moving parts in the trolley, hoist, and end carriages than more intricate systems, its straightforward design meant less wear and a decreased likelihood of unplanned malfunctions. Quick completion of maintenance procedures like brake adjustment, lubrication, and rope inspection would save downtime. In addition to offering durability, the structure's bolted girder connections and common steel grades made replacement or reconfiguration simple in the event that the customer's scheme altered later. Reliable long-term operation with low lifecycle costs was achieved by this combination of robustness and ease of maintenance.

1. Main components of the 10 Ton LD Single Girder Overhead Travelling Crane

We chose standard industrial materials so spare parts stay available. The layout keeps service points reachable. Controls and safety items are modular so you can add options later.

1.1 Main girder

The main girder is sized for your span and the 10-ton rated load. We use either high-strength I-section steel or a box girder when torsion or longer spans demand it. Connections between web and flange are bolted where transport or field assembly matters, and welded where a continuous section gives better stiffness. Materials follow common industrial grades (Q235B/Q345B equivalents). The girder is checked for deflection limits and fatigue life. We add local stiffeners and splice plates as needed, and we finish the steel with a corrosion-resistant coating for longer life in humid or industrial atmospheres.

1.2 End carriages and wheels

Wheels and carriages are matched to the runway and calculated wheel loads so the crane runs smoothly and wears evenly. The wheels are rolled steel with a standard profile for compatibility. Bearings come sealed to cut grease points and lower routine service. Axles and wheelsets are made for easy alignment, and wheels are replaceable in the field. We also provide provisions for wheel lubrication, runway adjustment, and inspection access so you can keep running without long stops.

1.3 Hoist
