Gantry cranes ni ubwoko bw'ibikoresho biremereye bikoreshwa cyane ku byambu, inganda zikora ibyuma, ububiko, pariki z'ibicuruzwa na sitasiyo z'amashanyarazi, n'ibindi.

Ibisabwa birashobora gutandukana cyane bitewe nububiko bwibicuruzwa. Kurugero, ibyambu bisaba cranes za kontineri zifite uburebure bwa toni nyinshi, mu gihe inganda ntoya cyangwa ziciriritse zishobora gukenera gusa cranes zifite ubushobozi bwo munsi ya toni 10. Ibikorwa byo hanze bisaba kurinda umuyaga n'imvura, mu gihe amahugurwa yo mu nzu ashyira imbere gukoresha ikirere.

I. Define Requirements
1. Ni iki ukeneye kuzamura? Imiterere y'imizigo igena ibipimo by'ibanze. Tekereza ikintu kiremereye cyane cyo kuzamura inshuro imwe kandi wemerere ikinyuranyo cyumutekano kiri hagati ya 10-20%.
2. Izakoreshwa he? Ibidukikije bigira ingaruka ku gishushanyo mbonera cy'umujyi wa Kigali. Gupima uburebure, ubugari n'uburebure bw'aho ukorera, kugira ngo umenye uburebure n'uburebure bwa crane ya gantry.
3. Izakoreshwa ite? Uburemere bw'akazi bugena igihe cy'ubuzima bw'igikoresho.    - Imikorere ya buri munsi yamasaha ≤5 hamwe no kuzamura ibipimo bya ≤30: hitamo icyiciro cyakazi cya A3-A4.    - Amasaha 24 ahoraho: Hitamo icyiciro cyakazi cya A6-A8.
II. Ibipimo birambuye bya gantry crane
1. Span and cantilever length
Span directly affects operational coverage. Considerations during selection:
- Standard spans: 5 m, 10 m, 16 m, 20 m, 30 m (custom non-standard spans available).
- Uburebure bwa cantilever: Hitamo 0-10 m cantilevers imwe- cyangwa ebyiri ukurikije ibisabwa n'ahantu. Irinde uburebure bukabije bwa cantilever.
2. Uburebure bwo kuzamura: Intera kuva hasi kugera ku gipimo cyo hejuru cya hook igomba kurenga uburebure bw'ibikoresho + umupaka wa 1 m.
3. Guhitamo sisitemu ya drive:
- Rail-mounted gantry crane: Suitable for fixed routes. Stable operation above 50T. Requires track installation.
Ferwafa ya gantry crane: Itanga uburyo bworoshye bwo kugenda kandi ikwiriye ibikorwa by'ahantu henshi. Ideal for 10-50 tonnes.
Crawler-mounted gantry crane: Adaptable to muddy/rough terrain, but sslow speed and higher cost
IMVAHONSHYA - Nyamasheke: Abaturage barasabwa kubyaza umusaruro ubuziranenge bw'ibinyabiziga
III. Gantry crane selection solutions for different industries
1. Ports and terminals: Container gantry cranes
Core requirements: High tonnage, efficiency and wind resistance
Recommended models: 40-100-ton rail-mounted container gantry cranes (RTGs)
Key configurations: Dual-container spreader, anti-sway system, GPS positioning and wind-resistant anchoring devices
Henan Mine Case Study: A customized 60-tonne container gantry crane was provided to a Southeast Asian port, achieving a handling efficiency of 30 containers per hour with typhoon resistance up to Category 12.
2. Inganda z'imiterere y'ibyuma: Portal cranes
Core requirements: Precise positioning, frequent lifting and adaptability to workshop environment.
Icyitegererezo cyashyizweho: toni 10-50 z'amashanyarazi za gantry crane (ubwoko bwa MH).
Key features: - Variable frequency drive
- Auxiliary hook (for lifting small components)
- Limit switches
Advantages: Henan Mine's steel structure gantry cranes use high-strength Q355B steel, reducing self-weight by 15% and energy consumption by 10%.
3. Warehousing & Logistics: Compact gantry cranes: flexible mobility, space-saving and easy operation.
Icyitegererezo cyashyizweho: 1-10 toni z'amapine ya gantry crane
Filed Under: Featured, Mu Rwanda Tagged With: Ibikoresho by'agateganyo n'ibicuruzwa by'agateganyo
Features: - Foldable design saves 50% storage space when idle
- Ibikoresho byifashishwa mu gutunganya amashanyarazi mu bice by'icyaro bidafite amashanyarazi
4. Hydropower stations: Portal hoists: high reliability, moisture resistance and precise control.
Icyitegererezo cyashyizweho: 20-200-tonne fixed gantry crane
Igishushanyo cyihariye: Moteri idafite amazi (IP67), kuvura ingese hamwe na sisitemu yo kugenzura kure.
Application case: A custom 160-tonne portal hoist was installed at a domestic hydropower station, achieving gate lifting precision of ±2 mm.
IV. Common misconceptions in gantry crane selection
1. Kwibanda gusa ku giciro: Guhitamo icyitegererezo gisanzwe giciriritse cyane utabanje gutekereza ku byifuzo byihariye by'imikorere. Prioritise critical configurations before considering cost.
2. Overestimating site load capacity: Installing rail-mounted gantry cranes without first verifying the ground's load-bearing capacity.
3. Kwirengagiza uburyo bwo kubungabunga: Guhitamo imiterere ifite imiterere igoye n'ibice byihariye.
Nk'isosiyete itanga crane, ibicuruzwa bya Henan Mine bikubiyemo ubwoko bwose kuva kuri 5 t-1200 t. Hamwe n'ibigo bya serivisi 428 ku isi yose, dutanga ubufasha bwuzuye mu buzima bwose bw'ibicuruzwa, harimo igenzura ry'urubuga ku buntu, igishushanyo mbonera cy'igisubizo, gushyiraho no kubungabunga buri gihe, gutanga serivisi yuzuye.
