These valves are used to lockout the control functions which can cause two-blocking. See How to Specify for choosing number and type. Perfect for older machines. Allows you to work on most job sites – and get more work for your cranes.

This section explains how to specify the size, number and voltage of lockout valves for your crane. These valves will most likely NOT be needed if your truck already has a factory installed anti-two-block system. The L25 will drive those valves. Please check with us to see if a relay kit might be needed. -
These 3000 psi valves are used to shut off crane functions on hydraulic cranes during a two-block (or overload) condition. Used on winch up, telescope out, boom down. They automatically allow corrective action: winch down, telescope in, boom up. -

These kits supply an external relay and installation instructions for driving existing OEM lockout valves on your crane when retro-fitting the L25 Radio Anti-Two-Block System. These kits, when properly installed, will insure that the L25 actuates your lockouts independently of any existing load system and will not interfere with their operation. -
These kits include some of the basic items we want on hand when installing one of these valves. The kits include 10 feet of oil resistant, flexible SO cable, crimp terminals, cable ties and the installation instructions. (We typically supply one kit per valve, so if you need purchase 3 valves, you would also get 30' of cable and sufficient terminals, ties etc. for 3 valves) -
Air lockouts and single lever control kits are also available for lattice cranes. These are used on air control systems which use 1/4" or 3/8" air lines. Typically found on American Cranes.
