Lever Blocks

 

Vital Lever Blocks NR-2 Series

 

The NR-series lever blocks feature the “free-wheeling” braking system which enables fast and easy operation.

There is a minimum load requirement of 10% of the Working Load Limit to ensure that the braking system remains operative and continues to support the load.

These lever blocks are ideally suited for the shipbuilding, construction, mining and power transmission industries.

  • Manufactured in Japan using optimum high quality steel which conforms to the strict JIS & ISO regulations.
  • All Vital models are manufactured to comply with AS1418.2.
  • One-touch operation for free chain adjustment.
  • Vital lever blocks can be supplied with overload protection for added security of use (excluding 250kg and 500kg models).
  • The unique design of the bottom hook prevents slipping and ensures safe operation.
  • Hardened alloy steel load chain with embossed identification, marked to the relevant standards.
  • Load Chain Exceeds Australian Standards with 5:1 Safety Factor.
  • Minimum load requirement of up to 10% of the Working Load Limit to ensure the operation of the braking system. E.g. a 1.5 tonne lever block requires a minimum load of 150kg.
  • Light loading; not suitable for tandem operations. If one of the lever blocks used in the tandem experiences an increase in the shared load and the other is reduced below the minimum load, inoperative breaks may occur and this could cause for the load to fall. For these applications we recommend the Vital Lever Blocks VR-2 series below.

Vital Lever Blocks VR-2 series

 

The VR-series lever blocks feature a “lock-in and lock-out” braking system which is the more traditional style with a free-wheeling system requiring the disengagement of the gear drive mechanism which is impossible with any load suspended on it.

These lever blocks are ideally suited for the (underground) mining, aerospace and energy industries.

  • Manufactured in Japan using optimum high quality steel which conforms to the strict JIS & ISO regulations.
  • All Vital models are manufactured to comply with AS1418.2.
  • Vital lever blocks can be supplied with overload protection for added security of use (excluding 250kg and 500kg models).
  • The unique design of the bottom hook prevents slipping and ensures safe operation.
  • Easy two-step operation to prevent accidental free-wheeling.
  • Hardened alloy steel load chain with embossed identification, marked as to the relevant standards.
  • Load Chain Exceeds Australian Standards with 5:1 Safety Factor.
  • The Vital VR-2 series are suitable for tandem lifting applications.

Beaver Lever Blocks

 

Heavy duty, available up to 9 tonne capacity, the V-Series industrial manual lever block is designed for a variety of applications in mining, heavy industry, major construction works and off shore exploration.

  • The V-Series Lever Block has all the features of the Beaver 3G lever blocks, with extra safety built into its design.
  • The load chain is made of high resistance, Grade 80 Alloy Steel, black finish, heat treated, calibrated and marked according to Australian standard of AS1418.2.
  • All Beaver lever block gears are fitted with industrial Roller bearings.
  • Incorporating a safety overload clutch (limiter) mechanism, an added safety precaution, as the handle cuts out at around 30% more than the rated W.L.L. to prevent severe overloading of the lever block.
  • Each 3G-V Chain Lever Block is operationally tested to its rated capacity and is supplied with a Beaver test certificate, relating to its stamped identification side plate.
