We are delighted to have the new CTL.476 and CTL.476p in our range of clamping hand knobs - while the CTL.476 series is probably more recognisible as a wing knob/wing nut – they compliment the whole Elesa series of lobe knobs, fluted grip knobs and scallop knobs for manual clamping applications.
The CTL.476 ( wing nut ) and the CTL.476p ( wing screw ) run from M4 with 20mm head to M10 with 56mm head in glass reinforced polyamide technopolymer.
As Standard Element specialists we at Elesa are pleased to offer the GN425.5 range of corrosion-resistant folding handles in stainless steel and polyamide. These folding handles offer major benefits in space saving and safety in confined spaces such crowded workplaces, narrow corridors or similar.
The GN425.5 series – from 100mm to 180mm – feature front M6 screw mounting into the polyamide brackets (with removable covers) which support the stainless steel (or chrome plated steel) handle, the handle itself being retained in its resting position by means of internal spring loading. Rugged industrial use is envisaged with functional performance up to 250°C and static loading up to a maximum of 500N.

Crank handles are probably one of the oldest forms of control element – just behind the hammer and the lever! Their use surely dates from the earliest machines with rotating parts – and today they continue to be a vital part of machinery operation. However their design fortunately has developed somewhat with the careful attention of our designers who have sought to ensure the optimum balance in ergonomic comfort and control.
Our wide range of Crank Handles encompasses older style DIN468 and 469 types, as well as modern balanced designs with eye-catching styling and up to the minute materials. Revolving handles come in palm fitting format as well as straight and folding configurations for use where a protruding handle may be hazardous, catch clothing or otherwise be unsuitable. The EIK crank handle in particular features the added safety functionality of an integral indexing plunger to ensure that the handle may not revolve, thus locking the setting in place for the required duration.
Arm handwheels such as our VB range and the ETK/EYK series are generally used where greater leverage is required, either because it allows greater force or greater delicacy and accuracy. They are often employed in the setting or operation of machines, valves, actuators, clamping or in rotational devices which require manual operation. They are frequently a superior solution to adjustment or control, in conjunction with digital position indicators where an electronic control system would simply over-engineer, over-complicate or over-price the application.
The VB198 moulded four arm handwheel at 170mm dia is suitable for fine single hand control or two-handed operation – likewise the VBR.4 with tubular metal handles in diameters from 200mm to 363mm. The VBR.2 matches the .4 but with two arms for lower cost. Three-arm handwheels with revolving handles from the ETK and EYK series are suitable for steering applications and have central hub colour indexing options – the ETK featuring straight revolving handles and the EYK having palm fitting revolving knobs where speed of operation is called for.
As standard component specialists we are proud of our 60 plus range of handles for manual machine operation. Such handles vary from small knurled knobs for instrument adjustment, to ball end knobs and cylindrical handles for lever arms or actuating levers and for clamping functions. Each family is available in many sizes to match all kinds of industrial, manufacturing and instrumentation requirement.
They are particularly suitable for applications on fitness machines, tools and machines for gardening and goods transport, high-precision instruments and disability aids.
This range of fixed and revolving handles are offered in a variety of tough materials resistant to the many solvents and cleaning materials encountered in machine environments such as production floor, disability equipment or agricultural operations. Typically, handles are manufactured in polyamide based technopolymer or high resilience polypropylene based technopolymer (for greater comfort), also phenolic based Duroplast and mirror polished aluminium. Lever arms are chrome plated steel with Duroplast knobs or handles.
Our fold away handles feature on many solid and spoked handwheels – and on crank handles – we believe this is an attractive and practical aspect of these important standard machine components. Fold away handles are frequently required in spaces where they would otherwise be a safety hazard, e.g. where the wheel is motor driven or where a protruding handle may catch clothing in passing by the equipment. By virtue of folding the handle itself into the body of the wheel, the problem is eliminated while retaining convenience and ease of use.
We have also managed to incorporate a fold away handle into the EMW monospoke handwheel and the MT crank handle. Revolving handles in resilient technopolymer or solid Duroplast are available to match the handwheel design.
We look forward to exhibiting our levelling feet, position indicators, handles, hinges, conveyor components and clamp mountings for electronic eyes etc. on our PPMA stand no F76 in Hall 5 at the NEC on 27-29th September.
Smooth contoured and graceful pull handles like our new GN665 have the strength for use on machine tools and large instrumentation while being especially attractive in reception areas on furniture or doors, and can be colour coded to suit custom colour schemes or corporate design styles.
The GN665 is constructed in oval section aluminium with zinc die mounts which ensure strong fixing and precise positioning. Complimentary Elesa products include levelling feet, industrial castors and lobe knobs, as well as two and three arm handwheels for applications from workshop floor to libraries.
These MMT handles are “cool” in all senses – stylish, practical and functional – they are particularly suited to applications where high temperature equipment requires manual operation. The MMT by virtue of its internal aeration channels and technopolymer insulation provides a significant “thermal break” and a relatively cool handle. Elesa’s MMT is thus suited to use on ovens and other machinery running at high temperatures.
Laboratory tests on the MMT show a thermal gradient of 110°C reduction from the mounting surface to the thermoplastic handle, enabling otherwise scalding hot material to be manipulated at comfortable hand temperatures.
We are delighted to supply the metal working industry with some “special” standard components which simplify equipment production while contributing to equipment operation when installed.
A good example of this is the range of LW.A vibration damping units which feature natural rubber damping pads built into an adjustable levelling foot design. They have been designed to damp vibrations, shocks and noise from moving components or non-balanced masses such as lathes, presses etc. This vibration can cause significant detrimental effects on operator health as well as malfunctioning/reduction-in-lifespan of the machine or adjacent equipment.
