Proof Engineering’s range of double-compression cable glands including the Orion, Crater & Taurus Exd AMPgland, ensures safe and efficient securing and sealing of cables in the mining and oil & gas industries.   “The AmPgland which is proudly our very own branded cable gland, offers an all-inclusive, electrical installation solution,” notes Donovan Marks, Managing Director of Proof Engineering, a Hudaco company that specializes in the manufacture and supply of a wide range of flameproof and explosion proof products. AMPgland’s unrivalled cable securing and sealing capability is du...

Proof Engineering’s range of double compression cable glands, including the Orion, Crater & Taurus Exd AMPgland, ensures safe and efficient securing and sealing of cables in the mining, oil and gas industries. AMPgland’s unrivalled cable securing and sealing capability is due to its unique design which features two O-rings on the shielding cone. The double compression O-ring ensures double sealing by preventing the intrusion of contaminants such as water and dust. Alongside achieving high strain relief and explosion proof protection, the special shape of the gland’s lower and upper seal al...

Couplers are traditionally manufactured from brass, leaded gun metal or stainless steel, making their high weight-to value ratio presents a theft risk. Proof Engineering therefore pioneered the ProAlloy zinc coupler, which offers reduced theft risk, lighter weight and lower cost. The ProAlloy is manufactured to specification from a zinc, copper and aluminium mix which holds no resale value, making it a “non-theft material”. The aluminium contaminates the mix and decreases the value from approximately R35/kg to R6/kg. The patented non-theft material also makes the couplers 33% lighter compared...

Couplers facilitate the connection of electrical cables to mobile mining equipment. The cost of replacing stolen couplers is often further exacerbated by subsequent downtime and production losses. In an endeavor to come up with a cost-effective solution for customers and end-users, Proof Engineering embarked on a three-year research and development programme and pioneered the ProAlloy zinc coupler. This revolutionary unit presents a three-in-one solution for industry – reduced theft risk, lighter weight and lower cost. Instead of the traditional materials, the ProAlloy is manufactured to spec...

“With our extensive footprint across Africa, we are adding even more value through this growing range of offerings. Underpinning our service levels is our process expertise that equips us to partner closely with customers in finding answers to their daily challenges.” Among the other items on display will be a large Cavex hydrocyclone with a substantial 1 500 mm diameter and weighing five tonnes. With the company’s leading position in pumping equipment, the stand will also display the impressive Warman 450MCR pump, measuring 2,5 m in diameter. Dust control and fire suppression solutions will f...

Component, equipment and system engineering specialist, Powermite’s range of electrical products manufactured locally by Ampco and Proof Engineering, are now combined under one roof in a new state-of-the-art manufacturing facility, enhancing products and service delivery. Ampco relocated to the manufacturing facility which is located on Johannesburg’s Westrand, in December 2013, and was joined in the November of 2015 by Proof Engineering and Azolite. “Pooling the talents and resources across both businesses has created the largest plug and socket manufacturer under one roof in Africa,” states ...

Couplers facilitate the connection of electrical cables to mobile mining equipment. “Given that they are traditionally manufactured from brass, leaded gun metal or stainless steel, the extremely high weight-to-value ratio of these critical components presents a high theft risk,” explains Donovan Marks, Director at Proof Engineering.  The cost of replacing stolen couplers is often further exacerbated by subsequent downtime and production losses. In an endeavour to come up with a cost-effective solution for customers and end-users, Proof Engineering embarked on a three year research and dev...

Proof Engineering, in collaboration with an end-user, has developed a tamper proof spindle that prevents the restrained plug from being removed without first isolating the circuit. “As specialists in the design and manufacture of innovative flameproof, explosion proof and non-flameproof plugs, sockets, adaptors and cable couplers for the mining and tunneling industries, we listen and respond to our customers’ requirements,” says Director, Donovan Marks. “So when a customer encountered a problem with the removal of the restrained plug from the socket which posed a safety risk to underground min...

Components, equipment and systems specialist, Powermite, alongside sister company, Proof Engineering, bring end-to-end cable and connector solutions for mining and industrial applications.  Powermite’s rugged range of TPU mining cables with flexible Class 5 tinned annealed copper wire conductors has been specially designed to withstand the hazardous conditions typically found in open cast mining. The copper-screened mining cables’ rugged design which incorporates a tough sheath, reduces the risk of cable damage and extends component service life.  “The resultant low maintenance lead...
