Technocrane Inc, one of Canada's major crane companies, now offers a reliable, versatile and affordable wireless remote control system suitable for small mono-boom and articulated cranes with low volume hydraulic systems. New BIGMAX cranes from Technocrane's stock can now be shipped with wireless controls. The BIGMAX crane products which are in service with manual controls will now be economically retrofitted with wireless controls.

Wireless controls were offered and used on large articulated cranes more than twenty years ago. Most big articulated cranes now come with wireless, or radio controls. However, most of the smaller mono-boom cranes (ie less than 4 t/m) have been manually operated using the hydraulic control valve on the crane.

Have you ever wondered why it took so much time for wireless controls to be accepted for small cranes? You can find the reasons below:

The first reason is that small crane operators can still manage without having to use remote controls. Small cranes have a shorter boom and therefore the load hook is usually less than 15 feet from the operator on the ground.

Secondly, reliable FAC approved radio controls have been too costly to justify. A small crane with wireless controls, in the past, could increase its cost by 50%. You could find cheaper controls options on the market; but they were not a reliable and safe option.

One more reason is, it really took time to own a small crane with wireless controls. In the past, if you wanted to own a small crane with wireless controls, you had to purchase from the factory in Europe with the lead times of 90 to 120 days. Radio controls could not be easily retrofitted to cranes in stock.

Technocrane Inc are now proud to be able to provide wireless solutions for small cranes. All of their BIGMAX cranes can now come with Hectronic wireless controls. According to Todd Slobogean, CEO of Technocrane, Hectronic has improved the design of their controls. Reliability is excellent and people have been able to purchase controls for a reasonable price for the first time. More interestingly, the radio controls can be added at the warehouse instead of the factory. Buyers do not need to wait for a long time to own a small crane with the equipment already installed at the factory anymore. This option saves them money as well.

Wireless controls are available with 3 or 4 functions as direct replacements for the original control valve. The Hetronic hand held transmitter is available with 4 functions with or without additional PMW toggle switches for other non crane functions.

The electronic control valve is sectional and proportional. It includes man-sized emergency, manual over-ride levers to allow the crane to be operated manually in the event of an electrical problem, or if the transmitter is lost or broken. The wiring harness, which uses DIN connectors, is weather proofed for outdoor use.
