Elesa has developed a range of security-focused components for hydraulic systems found in industrial and off-road machinery.

Hydraulic-based equipment, from dump trucks and road-laying machines to tractors, telehandlers and forestry or military vehicles, all operate in extreme conditions, are vulnerable to outside interference and are prone to damage from both daily operation and vandalism.

Elesa has therefore developed security-focused accessories aimed at prevention of leakage/damage to the hydraulic system – preserving the integrity of the system, so as to ensure that it has sufficient clean fluid at all times.

These are safety- and performance-critical components, which cover areas of personnel and equipment safety, while seeking to minimise downtime by reducing the likelihood of damage and simplifying/reducing maintenance.

Such components generally come into four main areas: vandal-proof caps that keep out dirt; pressure-relieving caps that keep in fluid; magnetic plugs that keep fluid clean of metallic particles; and fluid level monitoring and alarms to advise of adequate fluid levels.

Development technicians at Elesa recently addressed the problem of damage to sight glasses on tanks, which led to a shrouded version and an electronic version, which allows the gauge itself to be hidden from view yet give a clear readout to the operator in the cab.

In addition to visual readout of oil level, the HCX/E column level indicator features AC/DC electronic signal generation when the oil level drops to a minimum.

Fluid tank security can present difficult problems where conflicts between security and performance require careful attention.

The SFW/VP is a specific development of Elesa’s SFW series filler/breather caps, complete with overpressure vent and vacuum breaker features (to prevent under-pressure tank collapse in the event of sudden drainage).

The vandal protection design incorporates a special locking key that may be readily kept with vehicle ignition keys.

TVD series breather caps address the problems of venting toxic chemical reservoirs and tanks, especially during transit when there is risk of overturning and spillage.

They incorporate a vacuum breaker valve threaded to suit a standard 70mm inlet and ensure a complete seal in the event of overturning.

Simple oil level indicators allow rapid condition checks for level and temperature from 0 to 100C, while column level indicators give volume indications or max/min readings.

For those difficult high-pressure reservoirs, Elesa now offers the HGFT oil level window capable of withstanding up to three bar.

Where high temperature is also a consideration, the HGFT.HT.PR can withstand both 140C and up to 7-bar tank pressure.
