Possible record: strongest non-hydraulic robot arm can lift almost 3000 kg
The all-electric Super Jammer can handle heavy weights. It now wants to break the Guinness record. It has already proven that it can do it.

The old Guinness record for the world's strongest non-hydraulic robotic arm is shaking. The Super Jammer robotic arm from Rise Robotics has succeeded in holding a weight of 2930 kg in the air at a height of around 4.6 m and moving it back and forth. This was achieved by using the electric beltdraulic system, which works with belts, belt slides and belt deflections.
Lifting heavy weights with old pulley technology
The name Beltdraulic is deceptive. The system does not use any hydraulics with hydraulic fluid. Instead, Rise Robotics uses electric motors for the robot, which wind and unwind belts via deflection pulleys and thus develop the immense force required to lift heavy weights. The system has even more advantages: Because it works electrically, it requires no fuel and is completely emission-free, at least if electricity from renewable sources is used. It is also said to work more efficiently than other comparable lifting systems. Rise Robotics claims energy savings of between 65 and 90 percent.

The Beltdraulic is also said to be extremely durable. The robotics company claims that the drive can easily outlast the life of the machine in which it is installed. The system is also low-maintenance. The usual problems with burst pipes, heavy soiling and time-consuming repairs associated with hydraulic systems are eliminated. This also saves costs. The Beltdraulic system works with slide rails and rods that require little maintenance. Costs can also be significantly reduced here.
Beltdraulic also avoids another issue of hydraulic systems: hydraulic drift, i.e., the slight overrun of the movement. Operators can thus control the robot arm more precisely, without play or slippage. Beltdraulic is also said to be around three times faster than conventional hydraulics.

The previous record is held by the M-2000iA/2300 robot arm from Fanuc. It can handle weights of up to 2300 kg. The record has stood for almost ten years. The robot arm from Rise Robotics has already broken the record in a video, beating it by almost 635 kg. The company is now starting an official Guinness record attempt on March 20 at Union Square in Somerville, Massachusetts.
