Most freewheeling lever blocks in the industry have two potential hazards which contribute to failures onsite such as dropped loads. The hazards are light loading and brake lock outs.
What is light loading?
Most freewheeling type lever blocks require a minimum load applied to ensure full engagement of the brake. This can range between 3% to 5% of the product rated capacity, this percentage may vary depending on the equipment’s quality or condition.
There is a possibility that should the load not be sufficient to activate the braking system, the unit could malfunction, and it is for this reason that free-wheeling type lever blocks should not be used in pairs. For such applications, a non-freewheeling block would be considered. The Pacific G4 combines both a free wheel and non-freewheel system, all in one. It has a unique patented safety device that prevents light loading. It can function 100% efficiently at 0% load and can be used with any light load applied including tandem lifting. This makes it the safest lever block in our market.
What is brake lockout?
This is where the brake hub and spindle shaft can become compromised in the event of a twisted chain entering the block from the unloaded side. The force created can cause both the brake hub and spindle shaft to jam up resulting in the brake locking in an open state and dropping the load. The Pacific G4 lever block has been developed to prevent such failure.
Pacific Hoists products are designed and innovated with a safety-first focus so you can always be sure your application is safe!
