3 Hydraulic Jacks & Tools Jacks luminium hydraulic jacks model JH and model JS Capaciies from luminium jacks combine ligh weigh wih high lifing capaciy. The use of high ensile aluminium alloy allows lifing capaciies of up o 100 ons resuling in a very favourable 1.8 ons lifing capaciy per 1 weigh raio. Operaion of Yale hydraulic jacks is very simple. Jacks are supplied ready for use, i.e. including hydraulic oil, operaing lever and, where applicable, carrying handle and lifing claw. luminium jacks wih lifing claw JH-620 JS-104 Jacks from 20 ons are available wih a lifing claw. In his case he jacks are provided wih an elongaed base JS-65 plae. The max. permissible working load of he lifing claws is 40 % of he jack capaciy. luminium jacks wih safey lock nu Jacks from 20 ons can be supplied wih a safey lock nu. This device allows absolue safe jacking over a long period. In his case he hydraulic jack can be operaed like a mechanical suppor and he hydraulic sysem can be oally released. pplicaion Hydraulic jacks are universally popular ools for use in workshops or on sie for all kinds of lifing and assembly applicaions, for consrucion, shipbuilding, power plans, general engineering, meal fabricaion and many more. pplicaions are unlimied. Sandard jacks wih plain pison and jacks wih safey lock nus canno be used wih a lifing claw. To increase sabiliy, all jacks wih long sroke (305 ) are equipped wih an elongaed base plae. Feaures Srokes from Exremely low weigh. The 6.5 and 10 ons jacks can be operaed in any posiion (also upside down) and are equipped wih spring reurn pison and sop ring. The 20 o 100 ons jacks can be operaed verically or wih fron face in horizonal posiion. ll jacks are provided wih an overload proecion valve. From 20 ons capaciy wih addiional mechanical sroke limier. ll jacks wih hardened alloy seel saddle and sensiive lowering valve which is acivaed by he operaing lever. JH-630 SR 390

6 Machine jacks wih lifing claw model YM 2-15 Machine jacks wih lifing claw are used in applicaions where space below he load is resriced, hus prevening he use of radiional lifing equipmen. Typical applicaions for machine jacks are lifing, posiioning and ransporaion of machines, heavy seel consrucions or similar loads, as well as general repair and assembly applicaions. The jacks are also useful for applicaions like leveling of high-rise warehouses, heavy-duy scaffolds, large frameworks ec. Feaures Offers safe lifing of machines wih an exremely low clearance. Incl. safey pressure valve o preven overload. Large base offers increased sabiliy under load. Pump lever can roae hrough 270 (excluding YM-2). Same load can be lifed on eiher he head or he claw of jack. Spring reurn of he lifing claw (only YM-5 and YM-10). Precision-adjusable lowering valve. Jacks are supplied ready o use incl. pump lever, and are filled wih oil.

7 Hydraulic machine jacks model YP Hydraulic machine jacks are designed for he safe lifing and posiioning of machines and similar heavy equipmen. Feaures These jacks are operaed wih exernal pumps, e.g. hand or moor pumps bu also wih synchronous power packs. The compac consrucion allows operaion even in exremely confined areas. 3 hook-in posiions of he lifing claw provide high flexibiliy (model YP hook-in posiions). The load can be lifed wih eiher he lifing claw or wih he head of he jack. Welded, disorion-proof seel consrucion. High qualiy, durable hydraulic componens. The fla lifing claw allows low jacking heigh. Safe sabiliy due o swivel-mouned suppor fee. The connecion beween jack and pump is made by a hydraulic hose. The jacks are delivered ready-o-use inclusive of carrying handles and coupling half. Technical daa model YP Sroke Heigh for applicaions min. in Pressure max. bar Weigh approx.

8 Hydraulic machine jacks model YS 3-25 Hydraulic machine jacks are designed for he safe lifing and posiioning of machines and similar heavy equipmen. Feaures Inegraed hydraulic pump. Pump lever swivel mouned 270 for operaion even in exremely confined areas. Same load can be lifed on eiher he head or he claw of jack. Welded, disorion-proof seel consrucion. High qualiy, durable hydraulic componens. The fla lifing claw allows low jacking heigh. The addiional connec coupler (10 capaciy and larger) for exernal pump operaion, allows connecion of hand, moor or synchronous lifing pumps (max. pressure 520 bar). Safe sabiliy due o swivel-mouned suppor fee. Sensiive lowering valve for slow lowering of loads wihou jerks. When operaing he jack wih an exernal pump he insallaion of a manomeer is mandaory. The inegraed hydraulic pump is proeced by a pressure-limiing valve. The jacks are delivered ready-o-use inclusive of carrying handles, hydraulic oil filling and pump lever.

9 Hydraulic sage lifs model ST For compac, low-headroom and universal applicaions. Sage lifs are hydraulic lifing devices which are designed o lif and lower loads over high disances. Sage lifs overcome he usual limiaions of heir lifing heigh imposed by sroke lengh. Sage lifs operae wih double-acing hydraulic cylinders (reurn sroke by hydraulic pressure) and are equipped wih a load spreading plae and a pison suppor plae. Operaion sage lif operaes invered and lifs he load via he boom of he cylinder whils i climbs on a pile of suppor bars (wood or aluminium). In principle, he load can be lifed o any heigh alhough sage lifs are sill compac and versaile for low-headroom lifing applicaions. The simple 3-sep operaion eliminaes he need for addiional holding arrangemens and he reposiioning or replacing of cylinders which are normally required for a higher lifing disance. sage lif climbs up and down on is own. Conrol Depending on he power pack, seleced sage lifs can be conrolled individually (by hand or moor pump) or ogeher in a synchronized arrangemen wih muli-flow pumps. Feaures Yale ChroMo-Design. Low-cos lifing sysems possible, (3-poin resp. 4-poin). Low weigh (e.g. 60 for a 50 uni). Sage lif body made from high-grade aluminium. Hydraulic cylinders are made from robus chromiuolybdenum seel wih double bronze bearings ensure a longlife service sysem. Large-diameer il saddle. Incl. coupler halves and carrying handles on reques. 396
