BLOK products to improve crane productivity up to 32% 

The BLOK System currently comprises four products which can be used in a ‘pick and mix’ way for different handling systems or all together for maximum crane efficiency. 



The BLOK Rig mechanically fits and removes all four semi-automatic twistlocks (SATs) from laden or empty containers in seconds. 
BLOK Rig in use for Laden and Empty containers of any length can increase total Crane Productivity up to 6% and is safer for quayside operatives 


Two BLOK Rigs can be employed side by side for horizontal tandem lifting of laden or empty containers. Two BLOK Rigs can be controlled by a single technician. 
BLOK Rig in HTL mode, 2 x Empty containers, 1 x stevedore, 8 x SATs can increase total Crane Productivity up to 18% and is safer. 

BLOK Spreader  

The BLOK Spreader is an autonomous spreader adaptor which clips onto a single spreader in seconds making it able to lift two empty containers side by side in horizontal tandem lift (HTL). 
To enhance crane productivity further the guidelines of the United States, Occupational Safety and Health Administration can be followed with a BLOK Cert proof test for Vertical Tandem Lift (VTL) for VTL Containers prior to lifting onto the vessel resulting in Crane Productivity gains of up to 32 per cent.
