MAINTENANCE
approximately one hour and the entire system was transported on the highway without oversized load permits.
For Kal Tire and Komatsu dealer SMS in Fort McMurray, Canada, lifting trucks for maintenance and repair as well as tyre work is a common occurrence in oil sands and other mining sites. Safety while performing these operations is always a concern, and it’ s also important to do the job efficiently and quickly. The Enerpac Pow’ R-Lock offers continuous load locking technology and provides locking protection during lift, lower and hold functions. It is easily manoeuvered into position and with a simple twobutton remote pendant it can raise and lower from up to 20 ft away. The unit also meets the standards required to be used as a jack stand, which means no secondary jack stands need to be moved into place under the truck after it is lifted by the Pow’ R-Locl. This makes the process more efficient, thus saving time and money.
The JD Neuhaus extensive range of handling equipment, including hoists and cranes, are all engineered for extremes, providing safe operation in dust laden atmospheres or other explosion-hazardous areas such as chemical manufacture and mineral processing environments. All the JDN products, which include both compressed air and hydraulically operated units, are Explosion Protected as standard.
This ensures that all JDN products are safe for continuous and long-term operation in potentially explosive chemical atmospheres as well as the more insidiously dangerous conditions where high levels of airborne dusts exist such as in mining. This can include combustible dusts, high concentrations of airborne dusts, or wherever a dust cloud is confined with an oxidant present( ie typically atmospheric oxygen) and particularly where there is an ignition source. The oxidation of other commonly known materials such as coal can also be the source of a dust explosion.
JD Neuhaus says its easy to use Profi TI hoist range is“ the workhorse of the industrial world,” and the operating air supply can be set at 4 or 6 bar pressure, with a standard load lift height of 3 m being provided throughout. Other optional lift height requirements can also be specified and accommodated as required.
Their Profi TI range of air operated hoists includes a total of 19 models providing lift capacities from 250 kg up to an impressive 100 t. These incorporate many years of design and development, and have successfully proved their versatility and universal reliability following installations within a wide range of light, medium and heavy duty industrial workplaces. Their compressed air power supply is also utilised for control functions.“ It does not initiate sparks, so providing an unbeatable advantage when hoists are operating in potentially explosive atmospheres. Even greater safety can be achieved by the prevention of sparks generated by static discharges or metal to metal friction contacts.”
Standard versions of JDN hoists and crane systems( which utilise Profi TI hoists for lift operations) have the explosion protection / classifications and markings EX II 2 GD IIA T4 / II 3 GD IIB T4. Increased spark protection can be achieved, which involves copper galvanisation plating of the hoist bottom block and load hooks, together with fitting brass safety catches to achieve a rating of EX II 2 GD IIB T4.
“ With even further increased spark protection for explosion group IIC, the hoist horizontal movement trolleys incorporate running wheels and travel gearing which are manufactured in bronze for an impressive EX II 2 GD IIC T4 rating.”
All Profi TI hoists incorporate a top suspension hook, with optional overhead trolleys also available to accommodate lateral movement of suspended loads. Three trolley options incorporate load traverse movements combined with precise load positioning. One trolley is manually operated for horizontal movement of the suspended load. A second trolley has a manually operated reel chain mechanism for lateral load movements. The third motorised trolley provides traverse as well as load raise and lower movements, together with precise load positioning, utilising compressed air power. All trolley systems can

Innovating for ground support safety and quality of installation – since 1984
MacLean rock bolting technology was introduced over 30 years ago, and since that time the MacLean Bolter has gone on to become a staple for primary and secondary ground support in the Canadian mining industry, and increasingly in hard rock mining hubs around the world.
The 2016 release of the MacLean 975 Omnia Bolter responds to mining companies’ evolving ground support needs, including the demand for increased versatility( bolt type and length, deck height), increased productivity( compressing the mining cycle), improved worker safety( face bolting, resin injection and single-bolt handling), and the option of a diesel-free work environment( battery propulsion).
We are proud to support the South African mining sector out of our branch in Parys, where MacLean technical, aftermarket, and account management teams provide RSA customers with incountry service and support.
