How much payload can the zeroG® arm support?
Payload capacity can range anywhere from 0 to 36 lbs (16.3 kg) using standard product components. Current zeroG®4 models support 8 to 36 lbs (3.6 kg to 16.3 kg) of payload. zeroG®2 provides for total payloads up to approximately 10 lbs. (4.54 kg). Note that an estimate for the weight of the gimbal or end effector used to hold the tool or component is included in the above capacity estimates.
What applications can zeroG® arms support?
A cornerstone of this technology is its use of innovative gimbal designs that allow zeroG® to hold and manipulate virtually any tool or component. Equipois has successfully used zeroG® technology to hold and manipulate sanders, grinders, drills, impact wrenches, torque guns, nut runners, rivet squeezers, crimping tools and pulse guns, among other tools. We have also used the arm to support component parts where a part is being brought to a stationary tool such as a belt sander.
Where do you mount (install) the arm?
The zeroG® system is designed with a versatile mounting block that can readily attach to virtually any location. Bolt holes are included on both sides of each block at standard widths; a 1.125” hole is also included for pole mounting. This configuration allows the zeroG® system to be mounted to tool carts, bench tops and table tops, linear slides, overhead rails, mobile stands and virtually any other structure that has sufficient weight and stability to support the movement of the arm and payload at full extension. It should be noted that zeroG® arms are extremely lightweight to begin with the zeroG®2 weighing 7 lbs (3.2kg) and the zeroG®4 weighing 11lbs (5.0kg.) Eqiupois also offers a wide range of mounting solutions utilizing its Universal Mounting System, which includes floor posts, mobile stands, gantries, and chair mounts.
What is required for maintenance?
Very little maintenance is required for zeroG® systems aside from regular cleaning and occasional lubrication. A complete maintenance schedule is available upon request. The robust design of zeroG® allows for operation in even the most challenging industrial environments. Standard covers are available for environments that are dirty, have grinding sparks or contain corrosive contaminants.
Are there any safety or environmental issues to be concerned about with the arm?
The zeroG® system has attained CE Certification after undergoing rigorous testing relative to safety and industrial use. Potential pinch points are clearly marked and can be shielded using available covers, which also serve to protect the arm from the working environment. Please see our user’s manual for relevant safety instructions and warnings.
What is the process for replacement parts? How fast can we get replacement parts?
In the event they are needed, replacement parts for zeroG® arms are readily available and in stock at the factory. They are also available from some select local distributors. Equipois also maintains complete replacement arms in stock in the event of a system failure.
What is the expected lifetime of the zeroG® system?
System life is dependent on a number of factors, including duty cycle, range of motion required, and payload. zeroG® Labs has successfully tested the performance of the zeroG® for millions of cycles with rated payloads through full range of motion. Equipois can provide service intervals and replacement kits for high cycle applications.
What is the zeroG® warranty?
The standard zeroG® arm system comes with a warranty of 12 months from date of installation or 18 months from shipment, whichever occurs first. Extended warranties and service plans are available as an option for all zeroG® systems.
How do I adjust zeroG®?
The zeroG® system can be adjusted using labeled knobs located on each arm link. There is an adjustment for ‘Lift’ which modifies tension in each spring to provide the desired amount of lift assistance. There is also an adjustment for ‘Rate’ which fine tunes the performance of the arm for particularly heavy or light loads. Our user’s manual includes detailed instructions for adjustment of particularly heavy or light loads. Our user’s manual includes detailed instructions for adjustment of the zeroG® system.
If zeroG® moves so easily, how do I make sure it doesn’t drift when not being used?
One of the unique features for the zeroG® is ‘centering’ technology that provides lateral control of movement in the horizontal plane when desired. Centering is accomplished through two mechanisms: First, the use of a leveling mechanism in the 2-axis mounting block allows users to ‘balance’ the arm after it has been set-up at a location so that it is level with the ground. Second, gas springs located between the links of the arm give the system a slight ‘bias’ towards the intended area of use and limit the angle of rotation at the hinge. As an additional level of safety and control, zeroG® systems can be fitted with optional ‘docking’ components that allow the arm to be locked into a fixed position while not in use.
Can I mount zeroG® to moving structures, like a man lift or overhead conveyor?
Due to its light weight and versatile interface mounting blocks, the zeroG® can easily be mounted to man lifts, scissors lifts, overhead rails, 80/20 type rails and a number of other easily portable mounting locations. Care must be taken to ensure that the lift provides the necessary stability to hold the zeroG® system when fully extended at maximum payload. Equipois’s Universal Mounting System also offers a wide range of mobile stand, jib and gantry solutions that are specially designed for the unique moment loading requirements of zeroG® systems.
How do I manage the cabling required to run the tool at the end of the zeroG® arm?
Typical tool utility requirements often include compressed air, hydraulic hoses, electrical cables, as well as dust collection hoses. All can be mounted along the bottom of the arm using ties or clips, or contained within the optional protective covers.
What is involved with zeroG® installation?
Due to the portability and configurability of the zeroG® arm, it is very simple to install and operate. A typical installation (excluding ancillary equipment) should take less than an hour.
Does zeroG® require training to operate?
The zeroG® technology is intuitive to use, allowing operators to use essentially the same motions as they would with the help of zeroG®. Minimal training is required other than limited safety and operations instruction. Custom training and support is available in person or through online tutorials and sessions.
Can I use zeroG® to lift items other than tools (i.e. material handling)?
A version of zeroG® is under development that will provide dynamic lift for “pick and place” operations. Please contact us for more information.
Can I use zeroG® as a torque arm?
Current zeroG®4 products do not provide independent torque reaction. They will work with torque tools where a torque reaction bar or other mechanism is in place to accept torque or where torque can safely be absorbed by the operator. Because the zeroG® system allows workers to maneuver heavier payloads, the system may allow use of a torque reaction bar that may currently be prohibitive due to weight.
Can I use zeroG® with a paint gun or welder?
zeroG® can be used with paint guns and welding torches. Proper covers and other protective measures (i.e. grounding) will be employed with these types of tools to ensure the reliability and safe usage of the arm.
What about a harness mounting or other body mounted solutions?
We are in the process of developing body-mounted versions of the zeroG technology. Please contact Equipois for more information.
Can I test a zeroG® for a trial period?
zeroG® technology has been deployed in a wide variety of applications at many of the largest manufacturers in the world. We encourage you to explore some of the applications already performed using zeroG® technology and speak to our many references. In the event that a trial is still required, Equipois offers several programs including a ‘Try-Before-You-Buy’ program which allows users to trial zeroG® for a low monthly rental cost. Please let us know what your needs are and we will work with you to accomodate them.
What information do you need to give me a quote?
In order to determine the optimal zeroG® configuration, we collect some basic information regarding your application. Typically, we need to know tool manufacturer and model; tool orientaions during use; approximate work area dimensions; and potential mounting locations. We welcome you to provide us this information directly through our application questionnaire available on-line.
