REDUCE THE TIME, COST, AND RISK OF MOVING LONGWALL MINING MACHINERY

Conditions in a longwall mine play havoc with traditional staple-lock and super-staple-lock couplings. Operating pressures of 5,000 psi in the hydraulic hoses connecting the shields on your longwall miner put 60,000 ft-lbs of force against the fittings. That’s a lot for a staple to withstand. Moreover, hoses and fittings are subjected to pressure spikes from pumping equipment, impulses from the self-advancing shields, corrosion created by coal dust and moisture, and highly emulsified hydraulic fluids. After months in this environment, staples become corroded and deformed. They fuse to the...

WHAT MAKES THE GATES iLOK COUPLING UNIQUE? Gates iLok coupling is designed to realize dramatic reductions in downtime when moving and re-assembling longwall mining equipment. Compared to a staple-lock coupling, it’s simpler, safer, and faster. SPEEDY CONNECT AND DISCONNECT Gates iLok coupling is a threaded design with coarse, ﬂattened threads to allow hand-tightening. It can be connected in seconds. Disengaging the connection is quick and easy too. Simply cut and remove the cable lock and turn the swivel nut counterclockwise 2-1/2 turns by hand. Slots on the swivel nut accommodate a spanner...

DAMAGE RESISTANT The iLok seal fits inside the female end, less subject to accidental damage. The sealing surface on the male end is protected within the swivel nut. The open thread design resists damage caused by debris and corrosion. SPECIFICATIONS › Impulse tested to 133% of operating pressure at 250°F › COMPACT AND SMOOTH Compared to a standard staple-lock coupling, the iLok coupling takes up less space in the tight working quarters on longwall machines. Its smooth surface prevents abrading or snagging hoses or other equipment while being moved. DURABLE Rust-resistant plating, concealed...
