1 Important

This manual is a short summary of document “MM.SLC250.01E”

This summary has been created in order to make easier the assembly operations to the those lift operators

which already know all the contents of document “MM.SLC250.01E”, as in this reduced document some

technical details have been omitted. The ignorance of these details could cause a wrong safety gear’s

functioning.

In case of contradictions between this document and the “MM.SLC250.01E”, this last one has absolute

priority.

Neither SLC (Schlosser, Luezar & Cvr, s.l.) nor the manufacturer (Luezar-eco, s.l.) will be responsible for the

damages caused by the unfulfilment of the requirements established in MM.SLC250.01S (even if they have

been omitted in this document), and also the current standards and rules’s incompletion.

SLC (Schlosser, Luezar & Cvr, s.l.) reserve the right of modifying the contents of this document, without prior

notice. In this case, the document’s last modification will be the only valid one, which annul this document and

its previous versions.

2 General aspects

Please check that the data on the safety label is according to installation parameters.

Image 1 Label

S = S: standard, HS: High speed

Max rated speed = Maximum trigging speed

F. Nr = Fabrication number

F. Date = Manufacturing date

(P+Q) = Lift P+Q

E = Drawn guide

C = Mechanised guide

= Oiled guide (Yes / No)

The parameters have been printed by using undeletable ink, and the label is placed on the safety plates.

Forbidden:

a) Assembly safety gears with different fabrication number (right and left).

b) Using a safety gear for an installation with different parameters to the ones indicated on the label.

c) Handle over any part of the safety block, without Luezar-Eco S.L. ‘s authorization

3 Safety gear installation

There are 3 different assemblance depending on the linkage used:

SLC linkage joined to the safety gear: Proceed as indicated on 3.1 (page 3).

SLC linkage not joined to the safety gear: Proceed as indicated on the linkage instructions, and also

point 3.2 (page 6).

For other linkages: Proceed as indicated on the linkage instructions and point 3.2 (page 6).

3.1 Assembly instructions for safety gears including SLC linkage

Step 1 Place the safety switch Fix the safety switch Connect the safety switch, and test that, when

moving the rod, the switch works properly

Step 2 Fix the safety gear to the frame The UP mark stamped onto the safety gear must be always placed on the upper side. Check this before

and after the assemblance.

The SLC2500 safety gear must be placed on the frame in the way that the position regarding the guide is as

indicated in Annex I (pg. 7). These dimensions should be checked after the installation. In order to make easier

the installation, it can be used gauges, which should be removed after installation.

There are 2 possibilities for assembly:

- Oscillating system assembly: proceed as indicated on the oscillating system instructions.

- Fix system assembly: fix the safety gear using 4 Screws DIN933 M12 8.8 and 4 washers DIN 127,

proceed as following:

Step 3 Transmission bar adjustment Put the transmission bas through the linkage bushes (maybe you should loose the setscrew first). Place the bar

and then tighten again the setscrews, in order to fix the bar.

Step 4 Adjust the roller position If the roller must be adjusted loose (not releasing) the rod screws, move the rod until getting the right roller

position, (the SLC rods have a ± 1,25° regulation), and tighten again the screws.

Step 5 Adjust the recover strength The SLC linkage recover system can be adjusted, so you can regulate the necessary strength you need for

actuating on the rod. In order to regulate this strength loose/tighten the nut as showed in picture:

After regulating the recover system, check that

the spring has not been highly compressed. The

rod should get the engaging positions before

the spring is completely compressed. An

excessive tighten of the spring could cause the

system

Step 6 Check working Finally it’s very important to check that the assembly has been correctly made and all the parts work properly.

So you should move with your hand the linkage, up and down (simulating upwards and downwards actioning)

checking the following:

The safety gear is right positioned regarding the guide.

Both rollers get the engagement positions, and also they do it at the same time.

The movement is made without interferences from other parts.

The linkage recover system is able to recover by its own the roller rest position (otherwise see Step 5

page 5).

The safety gear switch works properly.

Note: In Annex I (pg. 7) position of the block regarding the guide is indicated.

3.2 Assembly instructions for other cases

In order to fix the safety gear to the frame, proceed according to Step 2 (Pg. 3).

The way to join the linkage and the safety gear may be different, but the most common options are:

o Roller with pin (most common): In case the roller includes a pin, the linkage should have a hole

available for introducing the pin into. (The rod hole should allow pin’s rotation). After putting

the rod into the pin, a washer should be used in order to prevent the pin hooked with the rod ,

and then the joint should be fixed by placing a pin DIN 94 or similar into the roller pin hole.

o Roller without pin (SLC linkages not joined to safety gear): in this case, proceed according to

specific instructions for each linkage model.

A safety switch must be connected in order to cut off when the linkage gets actioned.

After installing the system, check the correct working of the linkage, the safety gear and the safety switch, by

moving the linkage in similar way as actuating upwards and downwards, and checking:

The safety gear is right positioned regarding the guide.

Both rollers get the engagement positions, and also they do it at the same time.

The movement is made without interferences from other parts.

The linkage recover system is able to recover by its own the roller rest position.

The safety switch works properly.

Note: In Annex I (pg. 7) position of the block regarding the guide is indicated.
