Hydraulic and MechanicalPRESS BRAKES

The Unique Power System makes it PossibleHTC's patented hydrau lic-me chanical systemuses one heavy-duty hydra ulic cylinder toapp ly power to a pate nted , mecha nical" bell crank " type lin kage thus tran smittingup to 5 ti mes additional power to the ram(see diagram) .

Th is system is un ique because it offersthree spec ia l features together on onePress Brake.

• Full tonnage throughout the stroke.• Ram/bed parallelism throughout the

stroke.• Full tonnage doing off-center work.

Neither 2-cy linder hydraul ic brakes norcrankshaft mech an ical brakes can offer allth ree featu res in one mach ine.

Let's compare other Systems

LAC KS FULL TONNAGE OFF-CENTERBec ause most double-cylinder hyd raulicbrakes do not gene rate fu ll tonnage ineach of the two cylinders, 100%loading capabil ity is lack ing whenworking in an off-canter position.

DIFFI CULT TO MAINTAIN BED/RAMPARALLELISMDue to the inhe rent problems ofmaintaining true ba lance In the twohydraulic cylinders, It is otten verydifficult to maintain co nsta nt bee-to-remparallelism with a do uble-cylinderhydraulic Press Brake, part icularl y asthe machine ages.

Many t imes it willrequi re a larger capacity mechanicalbrake to accomp lish the same job ahydraulic-mechanical br ake can dowith less tonnage. This is due to thereduced capability of the fly wheeldesign as It encounters the work loadh igh er up In the st roke.

Check these otherOutstanding Features...EXTRA QUALITYHTC Machines are much heavier than many Press Brakes.Oversized stee l members are used for ext ra rigidi ty andopera ting smoothness. Heavy bronze bearing s at the pivo tpoints provide long wear and ram retention. Finally, HTCprovides a high-q ual ity, heavy-duty hydraulic cylind erfeaturing large bearing surfaces and an extra large rod.VERSATILITYA great range of jobs are possible. HTC Press Brakes cando a long draw with full co ntro l or it can be instantlyadjusted to short stroke so it can blank or punch at a highcycle rate per minute. (B lank ing or punching reduces normaltonnage to 2h of the rated capacity.)

SAFE TO OPERATEAn inexper ienced operator can handle an HTC Press Brakewith fu ll confidence that he is not likel y to harm himself orthe mach ine. Safety fea tures inherent w ith the HTC systemsuc h as ove rload protect ion, 100% ram cycle co ntrol andOS HA comp liance gi ve th is assu rance.SIMPLE, DEPENDABLE HYDRAULICSOnly co mmon domestic parts are used to insure a rel iabl epar ts replacement source. An interconnected high-pressurehose system provides HTC the flexibil ity to des ign the typeof system most like ly to meet your special needs. Thehose system acts as a natu ral shock da mpener wi thinthe total system.SHOCKLESS AND QUIETYou wi ll be amazed at the virtually shockless stroke of theram at full tonnage. It is smooth, quiet and the so und levelis significantly less than mechanical Press Brakes.

LESS TOOLING COSTSBecause of the smooth, shockless ac tion of the ram, manypeople save up to 50% annually on their repl acementtooling costs.EASY TO MAINTAINThere are fewer parts compared to most mechanical PressBrakes and together wi th the relatively simp le hyd raul icsys tem, a mai ntenance man will have less problems servicingan HTC Press Brake. In add ition, easy-to-understandservice manuals are shipped with each machine and aco mplete serv ice department is ready to hand le any prob lem .
