SRG safety shielding windows

For different applications, we provide a variety of shielding window types that run vertically, as well as security door types that run horizontally, which vary in their design and closing motion.

SRG shielding windows generally consist of a closed and very sturdy steel housing in which one or two window sashes or linear guides are supported, and they are motor-driven.

The window sashes, made of a welded aluminum tubular frame, alternatively are encased with aluminum sheet or transparent Makrolon. 

A standard three-phase current worm gear motor with an attached safety clutch and a closed steel drive chain make up the drivetrain of the window sash, which is built into the housing, in the center.
On all standard equipment, the window sash has, on its closing rim, a mechanical wedge that is lined with a rubber hollow section. The wedge is brought about in any arbitrary position on its guide shafts when operating a wedge of the window sash.

With the exception of the SRG-T shielding window type, window sashes that run vertically are counterbalanced using two counterweights. With the SRG-T type, the lower window sash in the opposite direction is set up with the counterweight to the upper window sash.

All shielding windows are equipped with automatic, mechanical locking, which prevents the window from being suspended from the closed position.

To activate the appropriate safety control, all shielding windows have standar equipment that includes 4 roll limit switches as per DIN EN 50041, which signal the following window positions:

 

  • Window open, motor cut-out point with the opening sequence
  • Motor cut-out point with the closing sequence
  • Window closed
  • as an option, window closed (2nd message) or window slightly open (antivalent message)

Because of their sturdy construction, SRG shielding windows comply with the requirements of a strict industrial firm as well as the requirements of the automotive industry. Linear guides, counterweights, drive elements and end switches are easily accessible via easy-to-open casings, and, in the closed position, they are well protected from contamination and contact.

SRG Design variations and options
  

 

Floor assembly (standard)

By default, shielding windows running vertically are equipped with 2 floor mounting plates, including levelling plates, shielding windows running horizontally with 2...4 floor mounting plates, including levelling plates for upright assembly.

 

Mounting frames +MRL, +MRR (option) 

A few shielding window types (see table) are also optionally available for suspended assembly with a separate mounting frame. In this case, the shielding window is equipped with lateral hinge lugs instead of floor mounting plates.

Such suspended shielding windows can be pivoted, for instance, for a die change within the mounting frame that is attached to the floor.

The MRL and MRR mounting frames vary in their hinge side:

+MRL

Hinge lugs left, stopper right

+MRR

Hinge lugs right, stopper left

 

Mounting frames +MSL, +MSR (option)

The MSL and MSR mounting frames match the MRL and MRR mounting frames; however, in addition, they are equipped on the stopper side with a mechanical locking latch counterpiece. In this case, the shielding window has the mechanical locking latch on the stopper side.

+MSL

Hinge lugs left, stopper right

+MSR

Hinge lugs right, stopper left

 

Mounting frames +MUL, +MUR (option)

The MUL and MUR mounting frames match the MSL and MSR mounting frames; however, they are equipped on the mechanical locking latch counterpiece with an additional electrical monitoring switch. In this case, the shielding window has an additional cam switch on the mechanical locking latch for the electrical monitoring switch.

+MUL Hinge lugs left, stopper right
+MUR Hinge lugs right, stopper left

 

Floor caster +BL (option)  

The floor caster ist another option for all shielding windows with mounting frames. It is screwed on to an additional flange plate on the shielding window side, and serves as a support roller when pivoting the window frame. In this case, the shielding window has a floor height of 150mm.

+BL Floor casters

 

Sheet metal coverings +V, +VS (option)  

By request, the SRG-B1+EH and SRG-B2+EH shielding windows running vertically can be equipped with additional sheet metal coverings which seal the area between the inlay height EH and the floor. These sheet metal coverings are available not only welded shut, but also screwed on:

+V Sheet metal covering welded shut
+VS Sheet metal covering screwed on

 

Additional back-ups +SLH, +SRH, +SLV, +SRV (option)  

Shieding windows running vertically with frame construction that opens downwards for accessible insertion spaces are optionally available with additional back-ups which can be mounted at the back or at the front on one or both sides of the frame. They facilitate the set-up and assembly of the shielding windows and provide not only a lateral limit of the accessible procedure range behind the shielding window but also useful procedure-related mounting possibilities for bexes used for storing small parts.

+SLH Additional back-ups, rear left
+SRH Additional back-ups, rear right
+SLV Additional back-ups, front left
+SRV Additional back-ups, front right

 

Window and door sashes FA, FM, FAM (standard)

The sashes for SRG all safety shielding windows and doors consist of a welded aluminum tubular frame with reinforced construction for increased breakdown protection, which is achieved using large junction plates and via intermediate braces. As an option, window and door sashes are overlaid at the front with

/FM Makrolon, thickness = 2mm
/FA aluminum sheet, thickness = 1mm
/FAM aluminum and Makrolon, with two-sash equipment

. 

 

Double glazing +D (option)  

Shielding windows and security doors with Makrolon sashes (FM) are available with additional, easily interchangable replaceable glass, which is attached to the back side of the sash with Velcro fasteners.

+D

 Double glazing

 

Viewing lenses +GS, +GM (option) 

Shielding windows and security doors with aluminum sashes (FA) are available with additional viewing lenses, which allow for an insight into the procedure range in the closed door position.  

+GS 110x90 1 welder glass in the clip-on frame width = 110mm, height = 90 mm
+GS 180x110 2 welder glasses in the clip-on frame width = 180mm, height = 110 mm
+GM width x height Riveted Makrolon viewing glass, width x height as per indication in [mm]

 

Device to prevent stepping behind +H (option)  

Shielding windows and security doors for accseeible insertion spaces are available with an additional device to prevent stepping behind, which consists of a padding plate that accompanies the window sashes and protects the accessible space between the shielding window and the procedure position

+H depth Device to prevent stepping behind depth as per indication in [mm]

 

Sound insulation design +S (option)  

All shielding windows and security doors are available in a reinforced sound insulation design, which is achieved by lining the frame housing with sound-insulating mats. In addition, the double glazing mentioned under the paragraph increases the level of sound insulation.

+S Sound insulation design
 

Laser protection design +L (option)  

The laser protection design consists of additional converings in the range of the opening edges, which prevent laser beams from escaping through the closed window.

+L
