KSSLS Three-Trolley New-Type Electric Hoist Bridge Crane

For paper mills and other plants where large components and maintenance tasks need several independent lifting points on one bridge.

The KSSLS three-trolley new-type electric-hoist bridge crane is mainly intended for large-workpiece handling and equipment maintenance in the paper industry. Three trolleys allow one crane to serve multiple lifting positions or support complex multi-point maintenance work.

The source emphasizes modular high-strength construction, large-diameter drums, dual-speed motors, VFD travel and low-headroom hoist geometry. Buyers should define how the three trolleys will be used: independently, sequentially or in coordinated multi-point lifts.

Product Overview

Mainly applied to large-workpiece handling and equipment maintenance in the paper industry.

Modular design and high-strength materials create a compact, lightweight structure.

Large-diameter drum and dual-speed motor support high-speed lifting and low-speed precision positioning.

For a new purchase, any capacity, span, speed, duty or positioning value that is not published on the source page should be confirmed from the actual project rather than assumed from a similar crane.

Why Choose KSSLS Three-Trolley Hoist Crane?

Three-Trolley Flexibility

Three lifting units can serve complex maintenance and multi-position handling tasks.

Paper-Industry Focus

The source specifically identifies paper-industry large-workpiece handling and equipment maintenance.

Dual-Speed Hoisting

High speed supports productivity while low speed supports precise positioning.

VFD Travel

Variable-frequency travel improves smoothness and load control.

Low-Headroom Modular Design

Compact hoist geometry improves building-space utilization.

Application Scenarios

How to Select the Right KSSLS Three-Trolley Hoist Crane

1. Define the Three-Trolley Work Sequence

Explain which trolleys operate separately and which may need to work together.

2. Provide Maximum Load per Trolley

Do not provide only total crane capacity; specify the expected load at each lifting point.

3. Define Load Geometry

Provide component length, center of gravity and pick-point positions.

4. Define Positioning Needs

State where low-speed precision positioning is required.

5. Confirm Building Headroom and Span

Use the workshop cross-section and runway data.

Safety & Control: What Buyers Should Confirm

• Rated-capacity and overload-protection requirements
• Upper/lower hoisting limits and travel limits
• Brake and emergency-stop requirements
• Electrical protection and site power conditions
• Operator control method and visibility
• Anti-collision, warning, synchronization or other project-specific functions where required
• Factory / site acceptance and load-test requirements

Installation & Maintenance

Before manufacture and installation, confirm runway span, rail or runway-beam condition, elevation, straightness, available headroom, electrical supply and erection access. Multi-trolley, suspended or cross-rail systems also require the relevant trolley spacing, support-point or transfer-interface data to be checked before production.

Maintenance should follow the final supplied crane manual and include the hoists, brakes, ropes, hooks / attachments, wheels, drives, fasteners, limits and electrical protection. Synchronized and multi-trolley systems should also include periodic verification of encoders, control logic and relative lifting position where applicable.
