Powerworks and Powerstart have been synonymous with reliable alternative starting for over four decades.
Powerstart Hydraulic Starters – Reliably starting your fleet in all conditions.
Powerstart Hydraulic Starters
Powerworks have been synonymous with reliable alternative starting for over four decades by means off our Powerstart range of Hydraulic and Air Starter motors. We were the first company in the world to manufacture cast iron hydraulic starter motors which are more robust and longer lasting than alternative materials. Cast Iron is especially suited for underground work where lighter metals such as aluminum are usually band.
Our success can be attributed to a total dedication to satisfying the needs of the customer in record-breaking time, thus providing first-class service to support our first-class products. We differ from most manufacturers in that our experience includes installing and repairing starting systems, thus giving us first-hand knowledge of real world applications and problems.
We already have hydraulic starting solutions for the majority of engine brands on the market but in the unlikely event that we do not have a hydraulic starter motor that can safely and reliably start your engine we have the ability to manufacture a custom made solution.
Powerstart hydraulic starters offer many advantages over electric starting which may vary depending on applications and environments:
How It Works?
Energy is stored in the form of hydraulic oil under pressure inside the piston accumulator. The oil is released either via a foot operated or solenoid operated start valve. Once released, the oil travels to the starter motor, which engages with the engine ring gear and begins to crank the engine. Once the engine has reached firing speed, the pinion gear is automatically kicked back by the ring gear.
The recharging of the system can be done manually by means of a hand operated pump, electrically by means of a hydraulic pump or even through the host machine’s on-board hydraulics if applicable.
With a range of 3 different physical sizes and 6 different starter displacements, engines as small as single cylinder water pumps and as large as 16 cylinder, 80 litre earth moving machinery power plants can be started. Powerstart hydraulic starters are made of rugged and durable cast iron and carbon steels and they are therefore safe for use underground where the use of aluminium or other light metals may be banned. Powerstart hydraulic starting systems can be purchased pre-assembled as mini-pak systems. These can be ordered with a variety of starters and accumulator sizes and they arrive completely assembled, piped and tested along with hoses and fittings so that all that is required is the fitting of the starter motor onto the engine and the fixing of the starting pack to any suitable surface.
The units comprise of an accumulator, oil reservoir, relief valve, pressure gauge, hand pump, foot valve, starter motor and hoses and fittings. Powerstart hydraulic starters feature a modular construction. This means that the flanges and pinions can be easily interchanged and as a result the number of possible starter combinations is literally limitless. As a result of this, new applications can be developed in hours and a finished product can be supplied in a matter of days.
