installation.
• The stepless holding brake (SHB) is
set to the specified nominal holding force.
• Observe the type plate
• The scope of delivery and delivery condition must be
confirmed immediately after receipt of the shipment.
LEANTECHNIK does not assume any warranty for
defect claims asserted after this time.
Report transport damage to the supplier immediately.
Incompleteness of the delivery and recognisable defects

4.2 Function
The spring-loaded, closed and pneumatically opened
stepless holding brake (SHB) clamps a profile rail in a manner
that is infinitely variable and free of play.
The spring-loaded system ensures the fail-safe principle
with the stepless holding brake (SHB) working as a safety brake.
• By venting the stepless holding brake (SHB) with the
required operating pressure, the clamping element
of the brake is pressed against the cup spring.
The profile rail can be moved (Fig. 1).
• By venting the stepless holding brake (SHB), the
cup spring acts on the brake's clamping element.
The profile rail is clamped (Fig. 2).
The maximum permissible sliding speed is 2 m/s.
Higher speeds on request

ATTENTION Brake may be damaged Removing
the transport lock (K) when the brake is depressur-
ised will result in damage. Only remove the trans-
port lock (K) (red screw head) when pressurised.
Caution Note the brake's own weight The brake
may fall during lifting / transporting. Crushing
and impacts may result.
Note!
The maximum clamping force can only be
achieved when the brake is depressurised.
Note!
If the operating pressure is too low, the
brake cannot be properly pressurised
(opened).
