Spoked handwheels with solid section

The solid rim of the handwheel allows the easy cleaning thanks to the absence of rear recesses. For this reason, being the technopolymer polypropylene based and the metal components in AISI 304 stainless steel, this version of VRTP. handwheel is designed for applications in food, pharmaceutical and medical fields.

Three-arm knobs

Glass-fibre reinforced polyamide based (PA) technopolymer, black colour, matte finish. VB.639/130: glass-fibre reinforced polypropylene based (PP) technopolymer, black colour, matte finish. This knob has been designed for heavy duty work where the use of a hammer for a firmer clamping action is required.

Adjustable handles

Particularly suitable when the lever turning angle is limited owing to lack of space. Compared to other types of adjustable handles with metal retaining screw this solution offers:

  • absolute electric insulation for the operator
  • no visible steel parts subject to rust
  • more comfortable lever release.
  • Adjustable handles are generally used for repetitive clamping operations sometimes with very high-frequency.
  • Therefore, the stress resistance (i.e. the resistance to repeated tightening cycles) of the handle unit is particularly important and, especially, the strength of the toothed element which transmits the tightening force from the handle to the threaded element (boss or stud).
  • In fact, the results of several laboratory tests, perfomed with a special instrument that simulates the most severe use conditions, have shown that e.g. ERX.78 adjustable handle can withstand without yielding more than 100,000 tightening cycles, under the action of a force of 490 N (see graphic).
  • The special glass-fibre reinforced technopolymer enables the ELESA adjustable handles to guarantee stress resistance values which are much higher than the ones generated under normal working conditions.

Levelling elements, fixed stem

Polyamide based (PA) technopolymer with adjusting hexagon, black colour, matte finish.

  • LX-SST: AISI 304 stainless steel threaded stem.
  • LX-SST-S: AISI 304 stainless steel threaded stem, base with screwdriver slot.
  • LX-AS-SST: AISI 304 stainless steel threaded stem, base with SBR rubber no-slip disk, supplied assembled to the base.

Vertical acting toggle clamps

GN 810.4 toggle clamps are latched in both end positions. In the clamped position, this prevents unintentional opening or opening caused by vibrations; and in the open position, it prevents self-closing of the toggle clamp, such as due to an extended clamping arm. The latching can be disabled with a single hand to allow for opening / closing.

They work according to the toggle principle: lever and clamping bar move in the same direction. In the clamped position the operating lever is in its vertical position.

Vertical acting toggle clamps in the U-bar version with two flanged washers (type BL) can accommodate an application specific clamping screw. A clamping screw with neoprene rubber tip is also included for type BLC.

Type FL version can either be utilized by welding the clasp which can then accommodate an application specific hold-down fastener component, or by utilizing the bar in conjunction with the GN 809 holders for clamping screws to hold the work piece in place.

Toggle clamps in the U-bar version with two flanged washers (type VL) can accommodate an application specific clamping screw. A clamping screw with neoprene rubber tip is also included for type VLC.

Oil drain plugs

Rubber buffers

The vibration-damping elements have been designed to damp vibrations, shocks and noises produced by moving bodies or non-balanced vibrating masses of equipment and machines which can cause: malfunctioning and reduction of the machine lifespan and/or of the adjacent ones; damage to health; noise. Load diagrams for each single code are available on request.

Levelling feet

The specified load in the table of the levelling feet GN 342.2 is a recommendation up to which the damping element can be permanently subjected. This static load equals a thrust on the area of 0.4 N/mm2 at which the damping material reaches its optimum dynamic damping ability. This also takes into account an additional load up to 0.6 N/mm2 in the event of a dynamic load. Levelling feet GN 342.1 cannot be disassembled.
