Lever blocks NR-2 and VR-2

Pacific Hoists would like to take this opportunity to advise users of the more popular “free-wheeling” type lever blocks that there is usually a minimum load requirement to ensure that the braking system remains operative and continues to support the load. In most cases, this minimum load requirement can be up to 10% of the Working Load Limit of the lever block – i.e. 150 kg for a 1.5 Tonne Lever Block, 300kg for a 3 Tonne unit etc.

There is a possibility that should the load not be sufficient to activate the braking system that the unit could malfunction and it is for this reason that free-wheeling type lever blocks should not be used in tandem. Should one of the units being used as a pair take an increase in the shared load and the other is reduced to below the minimum as stated above, then the one with the reduced share of the load may suffer from an inoperative brake and the load could fall.
Pacific Hoists Pty Ltd markets 2 types of Vital Lever Block. The NR type has a “free-wheeling” braking system which falls into the above category and the VR type which has a “lock-in and lock-out” braking system.
The Vital NR lever block is ideal for use where fast, one-handed operation of the free-wheeling system is required.

The Vital VR lever block is the more traditional style with a free-wheeling system requiring the disengagement of the gear drive mechanism, something that is impossible with any load suspended on it. Pacific Hoists Pty Ltd advise that both models comply with relevant Australian Standards.
