The client is a large-scale paper manufacturing plant in Bangladesh, specializing in the production of tissue paper, paper towels, napkins, and other hygiene paper products. With increasing market demand, the company expanded its production capacity by constructing a new drying workshop dedicated to handling large-diameter paper rolls. In paper manufacturing, handling finished paper rolls requires high precision and stability, as any deformation, edge damage, or misalignment can directly affect product quality and increase waste. The client needed a reliable and efficient lifting solution to support continuous production while protecting delicate materials.
Customer's Material Handling Needs
Within the new drying workshop, operators needed a reliable lifting solution to move freshly formed paper scrolls from the production conveyor to storage racks and drying frames. Key requirements included:
- Lifting Capacity: The crane needed to handle heavy paper rolls—up to 10 tons each—during stacking and transfer. In certain areas, lifting beams had to carry combined loads of 15 tons when moving multiple rolls.
- Wide Span Coverage: The workshop measured approximately 25 meters in width. The crane span had to cover the full clearance from wall to wall to allow unobstructed movement of paper rolls.
- Precise Load Control: Gentle handling was crucial. Paper rolls deform easily under uneven pressure, so the crane's hoist had to provide smooth starts, stops, and controlled lowering to avoid tearing or crushing the paper.
- High Duty Cycle: Three shifts operated daily. The crane needed to withstand continuous use—lifting, traveling, and lowering cycles—over an 18-hour production window without breakdowns.
- Limited Hook Approach: Space between the overhead beams and drying racks was constrained. The crane's hook approach and headroom had to be minimized to slide under low frames while still lifting large-diameter rolls.
Challenges with Previous Equipment
Before upgrading their lifting system, the paper plant struggled to keep up with growing production demands. The existing setup relied on several small 5-ton hoists and manual gantries, which were no longer suitable for handling larger and heavier paper rolls.
1. Inadequate Lifting Capacity
The first major issue was inadequate lifting capacity. According to the customer, with the increase in capacity, their production volume has gradually expanded, sometimes requiring the lifting of heavier paper rolls. Sometimes, for various reasons, cranes work overloaded. This increased the risk of overloads and equipment failure. It also created unsafe working conditions for staff. When your crane is not designed for your actual load, every lift becomes a potential risk.
2. Frequent Downtime and Maintenance
The older hoists and gantry systems were not built for continuous, high-frequency operation. During busy shifts, key components like bearings and motors would overheat. This led to repeated breakdowns and unexpected stops in production. Over time, maintenance costs increased, and production efficiency dropped. If your equipment cannot run consistently, it directly affects your delivery schedule and overall costs.
3. Damage to Paper Rolls
Damage to paper rolls was also a common issue. Manual handling and unstable lifting caused the rolls to shift or tilt during movement. This often resulted in torn edges or crushed sections. As a result, the plant had to deal with more material waste and additional rework. For the customer, this leads to higher production costs and lower production quality. Very unfavorable for the customer.
4. Limited Operational Flexibility
The previous system required a lot of manual input from operators. Workers had to guide and adjust each load by hand, which slowed down the entire process. It also made it difficult to operate safely in tight spaces around drying equipment. Without precise control, handling large paper rolls became both inefficient and risky.

Yuantai recommended a 15/10T double girder overhead crane tailored to the paper plant's drying workshop layout. This solution combined two separate crane units sharing the same runway: one 10 ton hoist for routine paper roll handling and a 15 ton hoist for stacking multiple rolls or carrying maintenance equipment. Key design features included:
1. Custom Crane Configuration
This tailored crane setup combines dual-capacity hoists, extended spans, and precise control to meet the unique demands of a roll-drying workshop. Each element is designed for safe, smooth handling of paper rolls and maintenance equipment.
2. Dual-Capacity Hoists
The crane features two hoists to match different lifting tasks. A 10 t hoist handles single paper rolls and offers a low-speed, high-precision mode for delicate placement. When operators need to move two stacked 7.5 t rolls or heavy drying-rack assemblies, they switch to the 15 t hoist. This flexibility reduces changeover time and avoids overloading any single unit.
3. Span and Headroom
With a 25 m span, the crane covers the full width of the drying workshop. It travels from the loading docks to storage racks in one continuous reach. Engineers set the minimum hook approach at 300 mm below the girder to let the hoist clear low-hanging drying frames. This tight clearance ensures the crane can slide under racks without obstructing the drum or tipping the load.
4. Rigid Trolley Design
The double-girder end trucks deliver high lateral stiffness to keep long paper rolls from swaying. Precision-machined wheels and axles guarantee smooth, low-vibration travel across the 50 m runway. This stability is crucial during roll changes, when even slight sway could misalign the load and strain the hoist components.
5. Advanced Wire Rope Hoists
Each hoist uses a frequency-controlled drive that adjusts lifting speed from 0.2 m/min up to its maximum rate. The 15 t hoist runs on a 45 kW motor, while the 10 t hoist uses a 30 kW unit. Both use 8×19 high-strength steel rope with a 5:1 safety factor to resist fatigue under three-shift operations. This ensures consistent performance over tens of thousands of cycles.
6. Control System
Operators move loads safely using a wireless remote control. This lets them stand clear of the load path and maintain full visibility. If the wireless link fails, a pendant station provides backup control. Both systems feature start/stop buttons, speed selectors, and emergency-stop switches for reliable operation.
7. Safety Devices
An overload limiter prevents the hoists from lifting more than 102 % of their rated capacity. Upper and lower limit switches on each hoist stop travel before the hook hits the beam or floor. Emergency-stop buttons located on the trolley and control panels allow instant shutdown in case of any hazard. These measures protect both personnel and equipment during daily use.

Performance in Diverse and Challenging Tasks
After commissioning, the crane demonstrated its ability to adapt to several demanding tasks:
- Handling Large-Diameter Paper Rolls: 2.5-meter-diameter rolls were lifted smoothly at slow speed. The crane's hoist maintained tension in the wire rope, preventing sudden drops when nearing the limit switches.
- Stacked Roll Transfer: Combined two 7.5T rolls (15T total) during peak periods. The dual hoist synchronized lift ensured stability, avoiding roll shifting and ensuring safe transfer to high-level storage racks.
- Drying Rack Maintenance: Removed heavy steel frames (12T each) from the top tier of racks for routine cleaning. The 15T hoist handled these loads without requiring a secondary jib or gantry system.
- Motor and Gearbox Replacement: During a scheduled shutdown, the 15T hoist lifted a 9T gearbox assembly to the roof-mounted crane positioner for routine inspection, showcasing versatility beyond paper handling.
- Emergency Load Recovery: In a power surge incident, both hoists automatically braked when power dropped below 20%. This prevented inadvertent load descent and allowed operators to reestablish power without load damage.
