Chain Hoist Nitchi H-50A

Learn More

Like the HE-50A series of chain block the H-50A is also compact and lightweight. The H-50A also features Nitchi's legendary durability and toughness. Double cover protection, load chain, load brake, reduction gear, hooks and load sheave characteristics are also consistent with the HE-50A series.

Two Independent Pawls

Failure of a pawl is very rare, but if one pawl should fail, the H-50A has a second backup pawl that will hold a load securely and prevent the dangerous free falling of the load.

Handwheel Cover

The newly designed handwheel cover not only effectively guides the hand chain into the pockets of the handwheel but also strengthens the handwheel cover for better protection.

Bearing 

The latest technology in bearing efficiency for chain blocks has led The Nich Co to the combined use of high-grade precision needle bearings, long wearing special hardened steel bushings and ultra modern carbon bushings. The bearing supported pinion shaft is a totally new concept in bearing efficiency for chain blocks. The carbon bushings and the precision needle bearings ensure a super-smooth operation and eliminate the possibility of pinion shaft seizures.

Safety Link

A specially processed safety link joins the endless hand chain and is designed to open slowly if the effort on the handchain is causing the chain block to be overloaded.

Safety Factor

The high safety factors of the H-50A assure maximum safety. The H-50A 500 kg to 3 tonne models are made with a 5:1 factor of safety and 5 ton and larger capacities have 4:1 factor of safety.

Convertibility

Besides conventional hook suspension systems, the H-50A can be joined directly to Nitchi trolleys enabling close headroom and or improved stability.

Interchangeability

All components are precisely manufactured by skilled craftsmen under high levels of quality control and are replaceable for easy and economical servicing.

Useful Manual

A comprehensive handbook giving detailed instructions and information on installation, operation and maintenance is supplied with each H-50A, with inspection certificate.

Optional Equipment

Listed below is some optional equipment available with the H-50A at moderate extra costs. Please contact your nearest Nobles branch for further information.

NN Chains

This is a series of standard chains with special non-electrolytic nickel plating that rigidly bonds itself into the material of the chains. This special plating called NN chains does not affect the original features of the chains and will not peal off like conventional surface plated chains. The NN chains have outstanding characteristics in resisting rust and corrosion caused by rain, seawater, steam and chemicals.

Chain Collecting Bucket

The chain collecting bucket can be easily connected to the H-50A without modifications.

Eye (Ring) Type Hooks

The ring type top and bottom hooks are ideal for all types of special applications.
