Compact 700 bar hydraulic tools from Enerpac (A Division of Actuant Corp) were employed by a Melbourne-based metal engineering company to streamline the manufacture of ergonomic and labour-saving flooring clamps.
John A.L. Mills and Associates combined its computer-aided metal design and fabrication skills with the power and precision of compact Enerpac 700 bar hydraulics to produce a custom-fabricated clamp highly suited for countries with a high proportion of houses with wooden floors and decks.
Employed on timber joists, concrete slabs, chipboards and with secret nailing, the flooring clamps that include a gap closer as standard are produced using an RC1010 cylinder located in a pedestal press and powered by a hands-free, pedal-operated PATG 1102N Turbo II air hydraulic pump.
The ergonomic hydraulic tools are used to produce an ergonomically designed floor tool with a rotating knob on its operating clamp that gives greater comfort in use, ease of operation and added safety by replacing a steel protuberance on earlier models.
According to John A.L. Mills and Associates’ Director Mr John Mills, the Enerpac hydraulic tools are used to cost-efficiently manufacture a flooring clamp that is much faster and less tedious than manual means.
The flooring clamp grips the joists and spacers to align the planks, providing drainage gap where required while the gap closer positions the planks close to the wall.
The high-strength alloy steel RC cylinders in capacities of 5-95 tons are part of an Enerpac range of safety-oriented, energy-saving and labour-saving technologies that use high-pressure 700 bar technology to reduce cylinder weight and size while maximising compact power.
John A.L. Mills and Associates’ 10-ton RC 1010 cylinder is safely and remotely actuated by the treadle-operated pump that leaves the operators’ hands free for any necessary adjustments.
A vee-block and ram are used to bend three of the flooring clamp’s components, employing Enerpac hydraulics because of the high force needed for the job and the fine control delivered by the hydraulics.
The ram and fixture are also used to drive in spring-pins that hold key sub-assemblies together, a more superior method to driving the pins in by hand as the power and control of the Enerpac cylinder minimises damage to the powder-coated body.
Enerpac hydraulic power is also used by the company to stake their thumbscrews together, crush the tube used on the floor clamp handles prior to fabrication, bend the rod for the actuator screw, and stamp their brand on certain components.
Key advantages derived by John A.L. Mills and Associates from Enerpac technology include achieving cost-efficient manufacture, capability for more in-house work and consistently high product quality.
Enerpac hydraulic tools have also increased the company’s capabilities whilst enabling them to stabilise prices, maintain profitability and improve productivity through smarter manufacture.
Enerpac’s single-acting general purpose RC cylinders and new RC Duo cylinders are available in 39 models with strokes from 16-362mm, and are part of a comprehensive range of high pressure cylinders trusted in Australasia for more than 50 years.
The RC and RC Duo range is complemented by a broad range of advanced pumping technologies from Enerpac ranging from simple portable hand pumps and versatile battery pumps to new generation electric and air-over-hydraulic technologies such as cool-running and energy-saving ZU4T electric pumps and new generation 700 bar XVARI XA air-over-hydraulic foot pumps.
