[A Time & Energy Saving Solution To Rebar Tying . . cont]
The DF 16 has other benefits that further improve productivity - ergonomic qualities. Instead of repetitive bending and twisting of the wrists, operators can work standing upright - a much healthier position - and effect ties without any twisting.
The device eliminates the positions that place a strain on the body and make tying with pliers risky because of the combination of bending and turning motion when twisting the wire and breaking it off.
In some countries, the cost of worker compensation for injuries can be substantial. In other countries, skilled workers not being available for work is an inconvenience and often involves additional expense.
Carpel tunnel syndrome, from repeated twisting of the wrists, is a common complaint with fixers and it can become long-term, leaving workers in chronic pain. Lower back pain is another common problem.
In view of the number of knots required on an average building site, which extends well into the thousands, this represents a significant reduction in physical stress.
Another benefit is that users can operate the device both horizontally and vertically with just one hand, leaving the other free for other jobs, such as holding the rebars in place. The DF 16 completely eliminates another step required when tying with pliers: the time-consuming removal of excess wire once the knot has been broken off.
This eliminates the need for clean-up work and the risk that any remaining wire will leave rust residue on finished surfaces - an important consideration when working with exposed concrete.
A Cost Efficient Multipurpose Tool
Apart from conventional steel fixing on concrete construction sites, the device can also be used for many other applications, such as core activation and electrical installation work, such as for heating, ventilation and air-conditioning (HVAC) systems. With the DF 16, heating pipes and conduits are as simple and precise to fix as reinforcing bars.
Weighing just 2.2 kg, the DF 16 is easily used with one hand. A telescopic handle is adjustable to suit people of different height to eliminate bending. There are no adjustments - the tie wires automatically adjust to the diameter of the material being tied.
Cartridges simply click into position. It operates in any direction, facilitating tying of material overhead or horizontally placed. The key to the DF 16 is its simplicity - no maintenance; no external or internal rechargeable power supply required and no special training.
As the video linked to this article shows, it could be the solution that the industry has been seeking for a long time.
