JENKA Lifting Keys — Threaded Lifting System for all load directions

JENKA Lifting Keys are used to attach the crane hook, lifting slings or chains to the JENKA Lifting Insert cast into the concrete element. Different JENKA Lifting Keys are designed for different load directions.

JENKA Lifting Keys can be used with all JENKA Lifting Inserts. Different JENKA Lifting Keys have different permissible load directions.

TLL Lifting Keys are for lifting angles of up to 45°, while TLP, JL and JLW Lifting Keys are suitable for angles of up to 90° and tilt-up procedures. In addition, TLP can rotate 360° around its own axis after screwing it firmly into the insert.

The JENKA Lifting Key thread must be screwed completely inside the insert. Lifting keys with wire have a color-coded Peikko tag. JENKA Lifting Keys are marked with a unique serial number indicating that they have been preloaded with at least 2.5 times the safe working load prior to the sale. All JENKA Lifting Keys are CE marked.

Model options

JL, JLW

JENKA JL Lifting Keys with metal lifting ring and JLW Lifting Keys with wire loop require the correct ring/loop direction to transfer loads to the insert and concrete. JL and JLW JENKA Lifting Keys are suitable for load directions between 0° and 45° and for 90° tilt-up procedures. Both lifting keys can be used for each load direction. When the lifting key is fully screwed in and tightened, a back rotation of up to 90° is allowed to adjust the ring/loop direction correctly toward the load. The length of JLWs can be customized with wire length upon request.

Comprehensive product information like resistances, required supplementary reinforcement, concrete grades, limitations of use etc. can be found within the Technical Manual. Product details may be country-specific. For design, always use product information that is localized for design's destination country. Country specific Technical Manuals can be found under Documents page, or from website of the country in question.

Model options

TLL

For the TLL loop, load directions between 0° and 45° are permitted. Tilt-up is not permitted with TLL Loop. The length of TLL can be customized with wire length upon request. TLL requires a smaller recess diameter compared to JL and JLW Lifting Keys.
