KSQX New-Type Double-Girder Suspension Overhead Crane
For workshops that need a double-girder underhung crane suspended from roof tracks, clear floor space and modern motion / monitoring functions.
Henan Mine Crane ksqx double-girder suspension crane showing the primary crane structure and lifting arrangement.
The KSQX new-type electric double-girder suspension crane uses two parallel main girders connected to end girders by high-strength bolts. The crane hangs directly from roof-mounted tracks, eliminating floor crane supports and preserving production space.
For procurement, the building structure is part of the crane system. Roof-truss capacity, suspension points, runway deflection, hook coverage and any optional side cantilever must be reviewed together with crane capacity and duty.

Product Overview
Two parallel main girders connected to end girders by high-strength bolts.
Crane includes travel mechanism, hoisting mechanism, electrical system and conductor system.
Directly suspended from roof tracks without ground support.
Where the source page does not publish a numerical capacity, span, speed, duty, positioning accuracy or other guaranteed performance value, the final value should be selected and agreed from the actual project rather than copied from a similar crane.
Why Choose KSQX Double-Girder Suspension Crane?
Clear Floor Space
Roof-suspended crane eliminates floor-mounted runway columns in the working area.
Double-Girder Suspended Capacity Platform
Provides a heavier underhung structure than a basic single-girder suspension crane.
Low Headroom / Hook Approach
Compact design improves usable building space.
VFD + Anti-Sway
Smooth motion supports higher-precision handling.
Optional Cantilever
Extends hook coverage beyond the nominal span when the building structure allows.
Remote Diagnostics
Supports monitoring and fault-diagnosis expansion.

Source-Confirmed Features & Buyer-Defined Options
Source-confirmed product facts:
- Two parallel main girders connected to end girders by high-strength bolts.
- Crane includes travel mechanism, hoisting mechanism, electrical system and conductor system.
- Directly suspended from roof tracks without ground support.
- Source lists VFD speed control, electronic anti-sway and high positioning accuracy.
- Overload protection, limit protection and emergency stop are source-listed.
- Optional side cantilever can extend working range beyond the span.
- Lightweight compact design reduces building load and construction cost according to source.
- Source highlights low headroom, small hook-to-wall distance, remote monitoring and fault diagnosis, plus intelligent-function expansion.
Buyer-defined items:
- Capacity and total suspended load

- Load geometry and lifting attachment
- Operating frequency and working duty
- Control and safety functions
- Positioning / synchronization / automation where applicable
- Installation, testing and commissioning scope
Application Scenarios
| Production Workshops |
Floor-free overhead lifting. |
| Assembly Areas |
Precise handling with anti-sway. |
| Buildings with Fixed Floor Layout |
Roof suspension avoids crane columns. |
| Extended Coverage Bays |
Optional cantilever beyond the normal span. |
How to Select the Right KSQX Double-Girder Suspension Crane
1. Verify Roof Structure
Provide roof-truss, support-beam and allowable-load data.
2. Define Suspension Points / Runway
Track layout and support spacing control building loads.
3. Define Hook Coverage
Include any required cantilever beyond the span.
4. Check Headroom
Provide roof, runway and highest hook elevations.
5. Define Positioning / Monitoring
State required anti-sway, positioning and remote-diagnostics scope.
Building Integration for a Suspension Crane
| Roof Loads |
Crane wheel/support loads must be coordinated with the building engineer. |
| Suspension Points |
Define exact support locations and structural steel. |
| Cantilever |
Optional coverage beyond the span changes support reactions and must be calculated. |
| Headroom |
Use the actual workshop cross-section to evaluate hook height. |
Safety & Control: What Buyers Should Confirm
• Rated capacity, overload protection and load-indication requirements
• Hoisting / travel limits, braking and emergency-stop requirements
• Attachment-specific safety such as magnet backup, grab interlocks, clamps or tandem synchronization where applicable
• Operator control method, visibility and safe access
• Anti-collision, anti-sway, positioning or automation requirements where required by the process
• Factory / site acceptance, load tests and project-specific functional tests
Installation & Maintenance
Before manufacture and installation, confirm runway span, rail / runway-beam condition, elevation, straightness, available headroom, power supply and erection access. Special attachments, multi-trolley systems, cantilevers, suspended runways and automated layouts should be coordinated with the workshop or yard drawing before production.
Maintenance should follow the supplied crane manual and actual duty. Inspection normally covers the hoisting mechanism, brakes, ropes, hooks / attachments, wheels, drives, fasteners, limits and electrical systems, with additional checks for magnets, grabs, clamps, sensors, encoders or automation hardware where fitted.

Frequently Asked Questions
How is the final crane capacity selected?
Use the total suspended load, including the load itself plus any beam, grab, magnet, clamp, spreader or rigging that remains below the hook.
Can the capacity, span and lifting height be customized?
Yes, these values are project-specific unless a source range is explicitly listed on this page. Provide the workshop / yard data for engineering selection.
What should I provide for a faster quotation?
Provide load drawings or dimensions, maximum suspended load, span, lifting height, runway length, operating cycle, environment and the specific process function that makes this product necessary.
Can control and automation be customized?
Where the source supports PLC, VFD, positioning, WMS/MES/DCS or remote functions, the final scope should be defined from the buyer's interface and acceptance requirements.
How should source-reported performance numbers be treated?
They describe the source product configuration. Any value that matters contractually for a new project should be written into the technical agreement and acceptance plan.
