KSSLE New-Type Double-Trolley Electric Hoist Bridge Crane

For long or complex loads that need two independent trolleys, synchronized tandem lifting or controlled balanced turning.

The KSSLE new-type double-trolley electric-hoist bridge crane uses two independent new-type hoist trolleys on the same crane runway. The source states that they can work independently or in coordinated operation.

The main buyer value is process flexibility: each trolley can handle different loads independently, while synchronized control can be used for accurate tandem lifting of long materials and balanced turning. The crane also uses dual-speed hoisting and VFD travel.

Product Overview

Uses new-type electric hoists with dual-speed lifting and variable-frequency travel.

Two independent trolleys operate on the same rail.

Trolleys can operate independently or cooperatively.

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 KSSLE Double-Trolley Hoist Crane?

Independent or Coordinated Trolleys

Each trolley can handle separate loads or work with the other trolley.

Long-Load Tandem Lifting

Synchronized control supports accurate two-point lifting of long materials.

Balanced Load Turning

The source explicitly states balanced turning can be performed through synchronized control.

Dual-Speed Hoisting + VFD Travel

Combines productivity with controlled positioning.

Compact New-Type Hoists

C-shaped arrangement reduces headroom and end approach.

Application Scenarios

How to Select the Right KSSLE Double-Trolley Hoist Crane

1. Define Load Geometry and Turning Need

Provide length, weight, center of gravity and whether the load must be turned.

2. Define Lifting-Point Spacing

Trolley spacing and travel range depend on the actual pick points.

3. Define Synchronization / Tilt Tolerance

State acceptable hook-height difference and rotation-control requirements.

4. Define Independent Trolley Loads

Specify maximum load for each trolley when used separately.

5. Confirm Span, Height, Duty and Headroom

Complete the standard crane parameters and building interface.

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.

What Information Do We Need for a Quote?

Frequently Asked Questions

Can the two trolleys work independently?

Yes. The source explicitly states independent and coordinated operation.

Can this crane turn a load?

Yes. The source states synchronized control can support balanced turning of long materials.

What information is needed for load turning?

Provide load dimensions, center of gravity, lifting points, desired rotation and allowable tilt.

Does the source confirm dual-speed hoisting and VFD travel?

Yes. Both are explicitly stated for the new-type double-trolley crane.

Can IoT monitoring be added?

Yes. The source states remote monitoring and intelligent maintenance can be expanded.
