overview
What this equipment is designed to do.
A single-girder overhead crane combines one main girder, end carriages and a lifting mechanism. Vertical hoisting and horizontal travel serve material transfer within an industrial building.
The supplied description identifies a welded-steel main girder and an electric hoist. It discusses frequent starts and stops, variable loads and the need to plan inspection and maintenance around actual workshop use.
The intended purchasing contexts include plant operation, fabrication, equipment distribution and workshop renovation. Small and medium warehouses, machining workshops and assembly or repair areas are described as application contexts; they are not presented as completed customer projects.
Capacity, span, lifting height, control arrangement and workshop interfaces need to be selected together. Source ranges below describe a family, not a confirmed bill of materials or a lifting approval for an existing building.
structure
Structure & installation interfaces.
Hoist and cross travel
An electric hoist provides vertical lifting and transverse movement; the source table names CD1 / MD1 lifting mechanisms.
Building interface
Runway support, clearances and available lifting height must be checked against the actual workshop. No dimensional or runway-reaction drawing was 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.
specifications
Capacity, geometry & control data.
Supplied technical table, transcribed without selecting a model. Ranges and options must not be combined into an assumed build.

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.
- Working-duty designation A3–A5 is listed, but no load spectrum, cycles-per-hour or test report is supplied.
- Runway reactions, wheel loads, hook approaches and installation dimensions are missing.
- Noise, positioning accuracy, safe working limits and load-test evidence are not quantified by supplied test records.
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.
Machining workshops
Intermittent movement of castings, machined parts and small moulds within compact production bays. Building structure and duty remain selection inputs.
Indoor storage
Pallet and semi-finished goods turnover inside enclosed warehouses, with overhead movement considered in the storage layout.
Auxiliary production
Material handling in hardware, food-machinery and small-equipment production; the source describes normal-frequency, light-to-medium duty contexts.
Assembly and repair
Occasional equipment overhaul, component fitting, disassembly and maintenance. Confirm the real load spectrum and required positioning.
These are application descriptions, not verified customer projects or delivered equipment references.
features
Configuration & selection considerations.
Structure and maintenance
The source describes a welded main girder, modular connections and access for daily inspection. Connection details and inspection access need a project drawing.
Clearance planning
Low-headroom arrangements are mentioned as options. Available hook approach and clearances remain unverified without dimensions.
Motion and controls
Cabin, pendant or wireless control and optional variable-frequency control are listed. The selected control scheme is not fixed.
Protection configuration
Overload limiting, travel limits, emergency stop, braking and buffers are named in source copy. Presence and safety ratings require model evidence.
Custom geometry
The source discusses alternative span and lifting-height arrangements. Final design calculations and building checks are pending.
Special environments
Anti-corrosion and explosion-protected versions are mentioned. Do not select them for a hazardous area without the relevant model-specific approval.
compatibility
Check the interfaces before selection.
Use the actual load, geometry, support structure, duty cycle, power supply, control scheme and environment to review suitability. No universal fit or suitability is assumed.
The source headline describes a 3–5 ton configuration, while its table gives a 1–20 ton family range. No individual model has been selected.
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.
Document availability, OEM / ODM scope, inspection, delivery, installation, warranty, acceptance and after-sales obligations must be agreed for the selected product. No fixed lead time, price, stock or performance promise is added.
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.
