EXTERNAL-pulling Sliding-arm pullers with constantly parallel jaws You should always give a 3-jaw puller preference if the access conditions permit. The uniform load distribution guarantees a particularly secure hold on the to be extracted part. Accessories: auxiliary grease hydraulic rams For use with mechanical KUKKO pullers from size 3. The auxiliary grease hydraulic rams are a good tool for significantly increasing the pressure when removing very secure parts. The hydraulic rams are simply secured between the spindle and shaft with the mechanical spindle. No conversion of the puller is needed! See also page: 16 Mode of operation as INTERNAL extractor STANDARD EXTERNAL EXTERNAL Accessories: Puller jaws Pullers in series 20 and 30 can easily be adjusted using different puller jaws lengths and types. external pulling is the most common type of pulling. The part to be extracted such as a gear wheel, pulley or ball bearing, is gripped from the outside. The part is loosened from the shaft by the pull of the pressure screw. The external pullers can also be used as internal extractors by turning the jaws. Important: When used as internal extractors, a fixed center point is required to brace the pressure screw of the products in these series. Accessories: Modular extensions For the 20 and 30 series, we offer modular extensions. If the part to be removed sits deep inside a shaft, jaw extensions will be needed. Which puller jaws are right for which puller? The puller jaws that start with 1- fit all pullers of size -1 and -10 The puller jaws that start with 2- fit all pullers of size -2 and -20 The puller jaws that start with 3- fit all pullers of size -3 and -30 The puller jaws that start with 3- can also use by the pullers of size -4 and -40 Example: 20-2 has the puller jaws 2-150-P can also use : 2-151-P; 2-152-P; 2-153-P can also use long puller jaws such as: 2-300-P; 2-301-P; 2-302-P; 2-303-P Safety instructions 3x Accessories: Side clamp The side clamp is available separately (No. 219-1). It is attached to the puller jaw after the puller has been fitted and prevents slippage of the puller jaw under very high forces. The puller must be centrally positioned for center shafts. If the shaft is not centered, pulling with parallel jaws may result asymmetrical pulling. If there are several parts to be pulled, always remove them one-by-one. Never remove several parts simultaneously. Jaws must always be positioned directly below the part to be removed. If there is adequate free space around the part, we recommend a 3-jaw puller for optimal force distribution. A 2-jaw puller is always used in situations where there is insufficient space for a 3-jaw puller. Accessories: Grease hydraulic pressure spindle The hydraulic spindle ensures controlled and secure operating of 7-20 t. It uses the entire capability of the puller, over and above what can be achieved with a mechanical spindle. When replacing a mechanical spindle with a hydraulic one, there is also a considerable reduction in the drive force which needs to be used.
