A Bangladeshi warehousing and distribution facility needed to upgrade its material handling. With Bangladesh's industrial expansion, the customer began receiving large, heavy machinery parts and dense raw-material bundles instead of only light cargo. The warehouse operations were inefficient and consumed valuable floor space. The client's challenge was to improve throughput and lifting capability within the constraints of an existing building. The plant had a standard steel frame, meaning heavy equipment would overstress columns and supports. Additionally, the customer was very cost-sensitive but demanded high reliability and safety. In short, they needed a cost-effective crane solution that could handle up to 10 tons without requiring expensive building reinforcements.
Project Requirements
The client needed a reliable overhead crane system to handle heavy loads in a busy warehouse. This was not a simple lifting task. The crane had to move large bundles and machine parts weighing up to 10 tons. It also needed to cover a wide span of 17.35 meters so that the entire bay area could be served without dead zones. At the same time, the hook height had to reach 10.5 meters. This allowed the customer to make full use of the vertical space inside the building. When you plan a crane project, these dimensions matter a lot because they directly affect your daily workflow and storage capacity. After reviewing the site conditions, we found that the existing runway beams had strict load limits. They could not support excessive wheel pressure. This meant the crane had to be strong but lightweight. Budget was another key concern. The customer wanted a cost-effective solution with a low total investment, including equipment and installation, but without compromising performance or safety. The crane also needed to support continuous multi-shift operation under A4 duty. Stable performance, overload protection, and long-term reliability were essential. This mix of high lifting demand, building restrictions, and budget control ruled out many common options. Forklifts and mobile hoists would take up too much floor space and slow down material handling. A heavier European-style HD crane would increase wheel load and exceed both structural limits and budget expectations.
Crane We Provided: 10‑Ton LD Overhead Crane
To meet the customer's production needs in Bangladesh, we supplied a 10-ton LD double girder overhead crane equipped with a CD/MD electric wire rope hoist. This solution was designed to handle regular lifting tasks under multi-shift operation while maintaining stable performance and long service life. The crane runs on the existing runway rails and fully covers the workshop bay. With a 17.35 m span, it provides complete horizontal coverage. With a lifting height of 10.5 m, it maximizes vertical working space and ensures efficient material handling across the facility.
1. Structural Design and Technical Specifications
The crane is rated at 10 tons and built under duty class A4 (ISO M4), which makes it suitable for moderate to heavy service conditions. We adopted a double-girder box beam structure made from high-strength Q345B steel. This design improves rigidity while keeping the overall weight reasonable. Two parallel girders share the load evenly, which greatly reduces deflection under full capacity, especially across a 17-meter span. The double-girder configuration also allows the hook to travel higher between the beams, ensuring the full 10.5 m lifting height is available without interference from the bridge structure.
2. Hoisting and Motion Control System
The crane is equipped with an CD electric wire rope hoist with double lifting speed. This allows precise positioning during light-load handling and efficient lifting during full-load operation. We integrated variable-frequency drives for bridge and trolley travel. This ensures smooth acceleration and deceleration, reduces load swing, and improves operator control. The crane supports both remote radio control and pendant control, giving operators flexibility and safer working conditions.
3. Quality, Safety, and Compliance
We manufactured the crane according to ISO 9001 quality management standards and CE certification requirements, as well as Chinese GB standards. Every structural component was carefully welded and inspected to ensure long-term durability. The double-girder design improves overall stability and operational safety. It allows the crane to withstand heavier loads and maintain performance over years of service.
Benefits of LD Type Overhead Crane
The LD type overhead crane uses a traditional and well-tested design. Its production process is very mature, which helps control manufacturing costs and ensure stable quality. For you, this means you can choose a crane that has been widely used in the market for many years. Under the same working conditions, Yuantai's LD overhead cranes are often 30% or more cost-effective than many other types of overhead cranes. This makes them especially suitable when your project budget is limited but you still need reliable lifting performance. Even with a competitive price, the crane does not compromise on capacity. It can achieve a lifting capacity of up to 32 tons, a span of up to 35 meters, and a lifting height of up to 50 meters. This allows you to use it in different workshop layouts and lifting scenarios with confidence.
1. Cost-Effective Without Sacrificing Performance
While price is an important factor to consider when choosing a crane, the performance and long-term usability of the crane is more worthy of consideration. Although the structure is simple, its working performance remains stable and efficient. It can meet the needs of most light to medium-duty lifting tasks in factories, warehouses, and production lines. You do not need to pay extra for complicated designs if your application does not require them.
2. Simple Structure and Lower Maintenance
The structural design of the LD type overhead crane is straightforward. It has fewer complex components and fewer wear parts. This means daily inspection and maintenance are easier for your team. Over time, you will spend less on spare parts and maintenance labor. The simple structure also reduces the chance of unexpected breakdowns. For you, this means less downtime and more stable production. A crane that is easy to maintain can bring long-term savings and peace of mind.
3. Light Self-Weight and Easy Installation
The LD overhead crane has a light self-weight and small wheel pressure. This reduces the load on your plant beams and columns. In many cases, you do not need additional reinforcement of the workshop structure. You may also avoid large-scale plant renovation. This can shorten the installation period and lower your overall project cost. If your factory building has limited structural capacity, this feature becomes even more important. It allows you to install a reliable lifting system without making major structural changes.
Key Solution Features
When choosing a crane for your operations, it's important to understand how each component contributes to performance, safety, and efficiency. The 10-ton LD double-girder overhead crane we delivered to Bangladesh was designed to meet these priorities. Every detail, from the main girder fabrication to the hoist and control system, was carefully selected to provide reliable, long-lasting performance. This crane is ideal for buyers who need both heavy-lifting capacity and precise handling in industrial environments, allowing you to move large loads quickly without sacrificing control or safety.
1. Box-Girder Fabrication
The main girders of this crane were built from high-strength Q345B steel plates, welded into robust closed box sections. Each weld underwent ultrasonic inspection to ensure there were no internal flaws, providing a solid foundation for heavy lifting. Machined splice plates and durable end trucks were bolted on-site, making installation faster and simpler. The box-girder design also offers excellent stiffness, which reduces bending under load and ensures smooth crane travel, even when handling the full 10-ton capacity.
2. CD Wire Rope Hoist
We selected a CD electric wire rope hoist with a 10-ton capacity for this crane, offering dual lifting speeds for versatility. This dual-speed operation is ideal for handling heavy materials efficiently while giving you full control during delicate load placement. The hoist runs on standard DIN φ15 mm wire rope and features a powerful geared motor with an electromagnetic brake, ensuring smooth starts and stops. This CD hoist enhances both speed and precision, making it a practical choice for industrial buyers who need reliable, safe lifting.
3. Variable-Frequency Control (VFD)
The crane's bridge and trolley drives are equipped with variable-frequency drives (VFDs), which allow smooth starting and stopping and fine speed adjustments. VFD control not only reduces energy consumption, but also minimizes mechanical wear and stress on the crane components. Positioning accuracy is improved, keeping loads within a few centimeters of the intended spot.
4. Controls & Safety
Operation is simple and flexible, thanks to ground pendant control and optional wireless radio remote operation. Safety is built in: the crane includes an overload limiter on the hoist, upper and lower limit switches for the wire rope, and infrared anti-collision sensors on both ends of the crane. Emergency stop buttons are strategically placed for immediate access. All safety features comply with CE standards and local Bangladesh regulations. With these measures, the customer can operate confidently, knowing the crane protects both operators and equipment during heavy lifting tasks.
Implementation and Quality Assurance
Throughout the project, we applied strict project management and quality control to ensure the crane met every requirement. Our engineers conducted a pre-installation survey to check runway geometry and support capacity. Certified technicians handled installation, following ISO and CE safety standards. Before commissioning, we performed full load testing, including a static test at 125% of the rated load to verify structural integrity and a dynamic test at full 10 t capacity to check smooth motion. We trained the client's operators on safe crane use and established a routine inspection program. The crane successfully passed all inspections, meeting Chinese GB standards and local regulations, and received a certificate of safe use. Delivery was seamless: the fully factory-tested crane, including the CD hoist, bridge, trolley, controls, and wiring, was shipped in modular sections to Bangladesh and reassembled on-site. The project was completed on time and on budget, and we provided full documentation along with agreed spare parts support to ensure long-term operation.
FAQs
Q: Why use a double-girder crane instead of a single-girder crane?
A: Double-girder cranes use two main beams, giving greater stiffness and capacity. This reduces deflection under load and allows longer spans. In this lifting project, the 17.35 m span and 10 t load made a double-girder design ideal: it kept bending minimal and raised the hook height for maximum clearance.
Q: What does "LD type" mean for an overhead crane?
A: LD is a common designation (especially in Chinese crane standards) for a conventional bridge crane design – essentially a top-running bridge crane. LD cranes are often lighter-duty and simpler than the European HD cranes. They are widely used in factories and warehousing. In our solution, LD implies a standard box-girder bridge crane optimized for light weight and cost, as needed for the customer's plant constraints.
Q: What makes this solution reliable?
A: The crane was engineered and built to proven standards. We used certified components (ISO/CE hoist, industrial-grade drives), strict quality control, and a design vetted by similar past projects. We cited real-world data. Customer support (spare parts and maintenance) ensures the crane stays reliable year after year.
