1 BOLTING TECHNOLOGY

2 Bolting Technology Yale bolting technology is the general term of reliable and proven equipment renowned world-wide for controlled tightening or loosening of bolted connections. The comprehensive range of products includes hydraulic torque wrenches for a maximum tightening torque of up to Nm, pneumatic torque wrenches for up to 4000 Nm as well as hydraulic bolt tensioners for a maximum thread dimension of M150. Hydraulic flange spreaders, hydraulic nut splitters and manual torque multipliers for up to Nm complement the portfolio. Special features of these products are their long service life, easy and quick maintenance and repair. All products from the bolting technology sector fulfil national and international regulations such as e.g. the EC Machinery Directive 2006/42/EC including corresponding supplements. It goes without saying that all torque wrenches are provided with a calibration certificate and operating instructions with a declaration of conformity or a manufacturer s declaration.

3 Bolting Technology Hydraulic bolt tensioners Hydraulic bolt tensioners model CST Bolt tensioners for friction-less and torsion-free tightening and loosening. Leight-weight and compact design, high tensioning forces for small outer dimensions. No torsional loading, only real pulling force. Manufactured from high grade alloy steel for longer lifetime. Each cylinder covers different stud sizes, only 6 different sizes cover stud-sizes from M20 to M64.

5 Hydraulic Tools HPS-2/4 A HPS-2/2 A HPS-2/0,7 A HPS-2/0,3 A Hydraulic hoses for the connection between hand pump and hydraulic cylinders need to be selected sepearately. See page 43. Hand pumps for single-acting cylinders model HPS Hand pumps are easy to use and operate independently of any external energy source. They are designed for a maximum 700 system pressure and will allow each hydraulic cylinder to utilize its maximum capacity. Features Operating pressure 700. Two-stage operation with automatic switch-over (except HPS-1/0,7 A). Large reservoir volumes. With pressure relief valves, adjustable from the outside. Precision-adjustable relief valve (handwheel). Robust all-steel construction. HPH pumps are equipped with a 4-way control valve plus a precision-adjustable relief valve. Oil port thread 3/8 NPT. Incl. oil filling.

7 Hydraulic Tools PAY-6-5 PAY-6 PAY-64 Mini hydraulic pumps model PAY With compressed air driven motor 700 These mini-pumps are driven by an air-powered motor and can be connected to any supply source of compressed air. These compact low-cost pumps can operate all single-acting or double-acting hydraulic cylinders up to a operating pressure of 700. Due to large reservoirs, large cylinders or multiple cylinders can be operated. The use of an inline air filterlubricator is recoended.

The manifolds are fully assembled and can be screwed directly to a hand pump or power pack. Depending on the way of assembly a short hose HHC-10 and a coupler half CFY-1 can be helpful. Manifolds models MY... GYA are equipped with the corresponding number of shut-off valves plus pressure gauge sets (GYA-63) which allow a permanent reading of each individual load.
