RGM Cranes has supplied a 30-ton semi-portal crane and two 10-ton single girder cranes to Betterect. The recent purchases stand testimony to the fruitful 20-year relationship between the two companies, which entails the refurbishment of Betterect’s existing cranes, as well as the load testing, servicing and inspection of Betterect’s four cranes every six months, and of their lifting tackle every three months.

Betterect has extensive experience in the fabrication and installation
of structural steel, plate work, mechanical equipment and piping. “We also have broad installation capabilities and often install free issue equipment and steelwork on large projects. “We are able to produce 650 tons of steel/plate work per month with our existing setup and, if required, we have the space and ability to increase this to 750 tons per month for specific projects,” says Francois Herbst, project engineer at Betterect.
Superior lifting combination
The single girder cranes supplied to Betterect are configured with a GMD-40 hoist unit and a Guralp pivoting end carriage. The GMD hoist unit has a number of features that ensure durability and longevity, including a monitoring system that records among others:
• the working time of the unit
• average load lifted and total safe working time
• complete operation numbers when the hook is loaded.
Other beneficial features of the GMD 40 hoist unit include:
• A Guralp electronic braking system, achieving one million
cycles before adjustment is required
• Guralp rope guides, which are hard-wearing, easy to remove
and replace, and are cost effective
• Overload sensor and hoist limit switch for enhanced safety
• Hoist motor/gearbox which has high-precision, long-wearing
helical gears; high start and stall torque; PTC thermistor overheat
• IP55 and IP65 protection class panels
• Soft start and stop with PLC and variable speed drive control.
The wheels on the pivoting end carriages are manufactured from
GGG70 sphero castings to provide high levels of tensile strength
and abrasion-resistance. The pivoting pin assists in preventing
any premature long travel wheel wear as a result of gantry/rail
High standard
“The quality and performance of RGM Cranes’ equipment is of
such an exceptionally high standard that our uptime on lifts is
efficiently maximised. Not only are the cranes characterised by
high performance levels, but they also focus heavily on safety in
design and operation, which is a critical factor for us given the
fact that they are required to undertake heavy lifts in populated
workshop areas,” Francois concludes.
RGM Cranes provides a full advisory service on fit-for-purpose
lifting solutions for a number of industries. Managing Director
of RGM Cranes Alex Dowling says, “We have amassed a wealth of experience and expertise in our 30 years of operation and we invite potential customers to put our team to the test.”
