1.High strength: Forged alloy steel resists fatigue and impact.
2.Efficient lifting: Precision crane hook block sheaves improve hoisting speed.
3.Custom adaptability: Sizes and crane hook block parts adjustable to suit different cranes.
The applications of crane hook blocks cover overhead crane hook block for workshops, tower crane hook block for construction lifting, crawler crane hook block for mining and metallurgy, and mobile crane hook block for ports and logistics.
1.Hook design: Streamlined to reduce stress concentration, flaw detection ensures no cracks.
2.Pulley system: Durable sheaves with smooth grooves minimize wire rope wear; sealed bearings extend service life.
3.Connection structure: High-strength bolts with preload prevent loosening; lightweight design reduces crane load.
Hanko Heavy Industry produces certified crane hook blocks with ISO and CE standards. All blocks pass NDT, ultrasonic tests, and overload inspections.

We are manufacturers of crane hook block, offering both standard and custom solutions for global customers.
Die Kraan-katrolstelsel gebruik verskeie katrols om vragte te versprei en die rigting van die tou te verander.
'n Gesmede kraanhaak is 'n sleutelligkomponent wat operasionele en vragveiligheid verseker.
Die veranderlike frekwensiemotor is 'n hoë-prestasie dryfoplossing vir hyskrane.
Die kraan se draadtafel is 'n noodsaaklike hysonderdeel in kraanstelsels. Dit draai die staalkabel op en af om vragte veilig en doeltreffend op te lig of te laat sak.
Die klipvinger-grypbak is 'n algemene hyserkomstuk wat gebruik word vir die hantering van los materiaal soos sand, gruis, steenkool, graan en erts.
Hanko-produkte word vervaardig met hoë-sterkte materiale en ondergaan streng kwaliteitsinspeksies om duursaamheid en bedryfsveiligheid te verseker.
Ons bied pasgemaakte vervaardigingsdienste vir nie-standaardonderdele gebaseer op klante se tekeninge of spesifieke vereistes.
Ons produkte voldoen aan internasionale standaarde en word wêreldwyd uitgevoer, wat die vertroue van kliënte oor Asië, die Midde-Ooste, Europa en verder verdien.
