Why a LOADMATE hd series.
Higher capacity
Reinforced design and multiple chain falls handle loads up to ~50 t.
Built for frequent use
Hardened chain and heavier gearing suit constant shop-floor lifting.
Custom lift heights
Extended lift and extra chain falls configured to your need.
Secure load holding
A Weston-type mechanical brake holds the load on release.
Longer service life
Heavy-duty components for repeated industrial lifting.
IS 3832 built & tested
Manufactured and tested to the Indian Standard with a certificate.
Two ways to specify it.
Hook-suspended
Anchored to a fixed beam or structure hook.
Best for: Fixed heavy lifting points.
Trolley-mounted
Mounted on a geared trolley to traverse a beam under load.
Best for: Moving heavier loads along a shop-floor beam.

HD Series — technical questions.
What capacity does the HD series cover?
Up to about 50 tonnes — higher than the portable block, for frequent heavy shop-floor lifting.
Is it still fully manual?
Yes — it lifts with the hand chain, so no power is required; multiple chain falls keep the hand-pull effort manageable.
Can I get an extended lift height?
Yes — lift height and chain falls are configured to your requirement.
How is it mounted?
On a fixed beam, structure hook or a geared trolley to traverse a beam.
How does it hold the load?
A Weston-type mechanical load brake holds the load securely the moment the hand chain is released.
Which standard applies?
IS 3832, with ISO 9001:2015 and ZED Gold certification.
