These requirements highlight the need for a hoist that adapts to varied work environments—indoors with limited headroom, outdoors on high-rise scaffolding, and in maintenance areas with restricted clearances.
Existing Problems Before Using Yuantai's Products
1. Oversized Hoist Dimensions
Initially, the customer considered a traditional low headroom wire rope hoist. This model met the lifting capacity and lifting height. However, its overall height reached almost 4 meters. In the client's workshop, ceiling beams and service pipes left only 3.5 meters of space. The 4 meter hoist could not be installed without modifying the structure. Modifications would delay the project and increase costs.
2. Inadequate Precision and Safety
The hoist previously in use lacked dual-speed functionality. Operators had to use a single-speed mode, which caused load sway during slow positioning. On narrow platforms, this led to damaged components and safety hazards. The existing control system offered only pendent control. In congested job sites, operators needed remote control to stay clear of moving loads and avoid risk of collision.
3. Long Lead Times and High Costs
The customer investigated a European style low headroom wire rope hoist. This model had a shorter overall height—about 3 meters. It met the headroom and lifting requirements. However, its lead time was 70 days. The project required immediate installation to meet contractual deadlines. Additionally, the European model carried a higher price point, straining the client's budget.
Solution 1: Traditional Low Headroom Wire Rope Hoist
Yuantai first proposed a 15 ton 40 m electric wire rope hoist with a low headroom design. Key features included:
- Low Headroom Structure: Reduces hook-to-girder distance. Designed to fit under limited ceiling clearance.
- Single-Speed Hoisting: Simplified lifting mechanism for rapid load movement.
- Standard Control: Pendent button controls for hoisting and trolley travel.
- Affordability: Lower initial cost compared to specialized European models.
- Shorter Lead Time: Quicker production and delivery compared to European alternatives.
Despite its cost-effectiveness and faster production, the customer found the overall hoist height—nearly 4 meters—unsuitable for their workshop. They needed a unit narrower than 3.5 meters. Therefore, this solution was not chosen.
Solution 2: European Style Low Headroom Wire Rope Hoist
To address the headroom constraint, Yuantai designed a European style 15 ton 40 m electric wire rope hoist with reduced dimensions. This model featured:
- Compact Hook-to-Girder Distance: Approximately 2.8 meters total height. Fits in limited headroom spaces.
- Dual Hoisting Speeds: 0–3 m/min for precise positioning and 0–10 m/min for fast lifting.
- Dual Travel Speeds: 0–5 m/min and 0–20 m/min for trolley and crane travel.
- Dual Control Modes: Wireless remote and pendent pendants for flexibility. Operators can stand clear of the load path.
- Dual Braking Systems: Mechanical and electric brakes. Ensures load holding during power failure.
Although this European style hoist met the dimensional and operational requirements, its 70-day lead time exceeded the client's project timeline. Its higher cost also conflicted with the client's budget constraints. Consequently, the customer sought an alternative that balanced compact size, advanced features, and prompt delivery.
Solution 3: 15 Ton 40 m Electric Chain Hoist
Yuantai proposed a 15 ton 40 m electric chain hoist with Schneider motor configuration and FEC load chain. This option overcame previous challenges:
- Low Headroom Design: The chain hoist's overall height is only 3.2 meters. It fits easily under the 3.5 meter clearance without structural modification.
- Compact Size: The hoist's narrow width and rounded body allow installation on existing I-beams with a 10 meter span.
- Dual Hoisting Speeds: Offers 0–2.5 m/min for fine positioning and 0–7 m/min for rapid lifting. This ensures gentle load placement and efficient vertical travel.
- Dual Trolley Speeds: Allows 0–3 m/min and 0–12 m/min trolley travel speeds. Operators can quickly move loads across the workshop or slow down near obstructions for safety.
- Dual Control Options: Includes both pendant control and wireless remote. Operators can choose the safest, most convenient method depending on the site conditions.
- Dual Braking Systems: Incorporates mechanical load brakes and friction disc brakes. Load remains secure even in case of power loss.
- High-Quality Components: Schneider electric motors, FEC load chain, and sealed gearboxes ensure long-term reliability and reduced maintenance.
- Shorter Lead Time: Manufactured in 45 days, meeting the client's urgent project schedule.
- Moderate Cost: More affordable than the European style low headroom hoist while offering advanced features.
This 15 ton electric chain hoist fully satisfied the client's requirements. Its low headroom profile and compact construction allowed easy installation under the existing runway.
