overview
What this equipment is designed to do.
Double-girder equipment with a European-style trolley and configurable frequency-drive controls.
Two main girders support a European-style hoist trolley. The source mentions a compact trolley envelope and optional auxiliary hook.
Integrated three-in-one drives and VFD controls are described for crane motions. Anti-sway and positioning performance remain untested.
Bolted connections, access components and optional monitoring appear in the source. No wheel-reaction table or structural calculation is supplied.
The table below preserves every supplied parameter row. Exact model association, drawings and test evidence remain open; source family maxima must not be combined into an assumed build.
structure
Structure & installation interfaces.
European-style hoist trolley
Integrated three-in-one drives and VFD controls are described for crane motions. Anti-sway and positioning performance remain untested.
Modular beam and end-carriage interfaces
Bolted connections, access components and optional monitoring appear in the source. No wheel-reaction table or structural calculation is supplied.
Engineering drawings pending
No approved dimensions, interface drawing, load reaction, wiring diagram or downloadable engineering file was supplied. Request the selected model and site-specific drawing before installation.

performance
Operating conditions & unverified limits.
The supplied material describes configuration options but does not include measured performance curves, a test method or an independently documented operating envelope.
- The listed duty, load and geometry ranges require a selected configuration and load spectrum; no load-test or engineering calculation was supplied.
- Source references to certification, full testing, reliability, price, export delivery and special-environment protection are not verified credentials or contractual commitments.
Test and performance evidence pending
No fabricated load curve, motor-power chart, noise result or safety rating has been drawn for this preview. Provide model-specific test conditions and reports.
applications
Source-described application contexts.
Steel billets, plates and profiles
Steel billets, plates and profiles are identified as cyclic handling loads; the actual spectrum must determine duty.
Heavy-machinery assembly
The source discusses machine tools, power equipment and pressure vessels during heavy assembly.
Foundry castings and forgings
Castings and forgings are described in foundry contexts; temperature limits need purpose-specific evidence.
Large mould storage and retrieval
Large mould placement requires selected speed, hook geometry and control data; precision is not guaranteed.
These are application descriptions, not verified customer projects or delivered equipment references.
features
Configuration & selection considerations.
Main / auxiliary hook options
The supplied copy lists main / auxiliary hook options. Two main girders support a European-style hoist trolley. The source mentions a compact trolley envelope and optional auxiliary hook.
Integrated VFD drive
The supplied copy lists integrated vfd drive. Integrated three-in-one drives and VFD controls are described for crane motions. Anti-sway and positioning performance remain untested.
Remote monitoring options
The supplied copy lists remote monitoring options. Bolted connections, access components and optional monitoring appear in the source. No wheel-reaction table or structural calculation is supplied.

proof
Certificates, drawings & project evidence.
Proof, downloads and video pending
No model certificate, test file, genuine delivery case, authorised customer reference, engineering download or product video was supplied. Source marketing mentions of certification or full testing are not displayed as verified credentials.
service
Technical support & order boundaries.
The supplied service description covers equipment selection discussions, customised drawing requirements, installation / operation documentation, procurement assistance and remote troubleshooting.

faq
Before requesting a quotation.
Which data should accompany an enquiry?
Provide load, span or outreach, lifting height, power supply, duty, environment and destination. Replacement parts also require the existing model and interfaces.
Are source ranges certified for every image?
No. Source values describe families and options. Exact model association, calculations, tests and certificates remain pending.
What are the lead time and warranty?
No confirmed terms have been supplied. Agree timing, price, warranty and service responsibilities for the selected configuration.
Is installation included?
Installation documents and remote technical support are described in source material. On-site work, commissioning and acceptance responsibilities remain to be agreed.
