Improving Workplace Safety with Custom Tool Balancer for Hytorc LST-2000 Torque Tool

The Problem with Heavy Tools

Bolting applications often require heavy tools such as torque wrenches and impact wrenches to achieve the appropriate level of tightness for bolts. However, handling these tools can be challenging and even dangerous. Fortunately, tool balancer arms can be used to counterbalance the tool’s weight and reduce physical strain, providing added support and balance for greater precision and control.

Recently, the FlexArm engineering team provided a counterbalancing solution for a customer with a unique application. They sought to improve workplace safety by finding a counterbalance solution for a 30-pound Hytorc LST-2000 electric torque tool. They use the tool atop a scissor lift, and this solution prevents the tool from being accidentally dropped off of the lift and causing serious injury. Additionally, the tool balancer reduces operator fatigue, which is known to lead to errors and accidents.

FlexArm's Custom Solution

To hold the Hytorc LST-2000 tool, FlexArm designed and manufactured a custom mount with the G-30 model arm. The custom arm is designed to counterbalance the tool’s weight and provide added support and balance, making it easier to handle. The mount securely clamps around the tool’s body using the exact dimensions of the tool for a perfect fit. The rotations about the vertical and horizontal axes (indicated by the arrows in Figure 1.) allow the operator to freely maneuver the tool as they desire.

FlexArm also provided additional components, including a latch to keep the parallel arms locked together and a rotation stop block to prevent swinging during transportation, making using the G-30 arm on a scissor lift easier.

The Benefits of Using a Tool Balancer Arm

FlexArm’s custom tool balance arm was a game-changer for the customer. It provides support and balance for the heavy tool, making it easier and safer to use. However, it’s important to remember that using heavy tools high in the air, such as on a scissor lift, comes with additional safety risks. Workers must ensure the tool is properly secured and follow all safety procedures to prevent accidents

FlexArm’s custom arms are a prime example of how specialized ergonomic solutions can improve efficiency and safety in the workplace. You know how challenging and dangerous it can be if you handle heavy tools. FlexArm’s custom tool balancer arms are tailored to meet specific application needs, making your work easier and safer.

Auto Stand-Off – This is currently defined to be surface stand-off and not to be confused with vector stand-off in 5-axis mode. The current auto stand-off is based on a changing surface and will adjust vertically based on the angle of the “A” Axis, so there is five (5) axis taken into account during the calculations, but this is not the same as the tool vector stand-off. There is the ability to do the vector stand-off change while the machine is running manually with buttons on the screen.

Z-Reader Probe – The Z-Reader is a device for mapping the location of the surface. It can be controlled manually & programmatically. The option is NOT active while cutting & is retracted out of harm’s way. It can be triggered to verify the surface at every pierce before the cutting process starts, or it could be used to drive surface mapping of the whole part before cutting starts. It begins with initialization or zeroing of the device to the surface at the beginning of a program and then accumulates or tracks the difference from that zeroing effort.

Automatic Edge Finder – The edge finder is or can be utilized manually (Jogging Method & Screen Buttons), programmatically (M & G codes), or fully automatic routine (dedicated program). This option sets offsets & program rotation to match the orientation & location on the cutting table.

AC Unit Installed on Electrical Cabinet – The unit is mounted on the cabinet’s High Power (480v) side. It is close to the location where the drives are mounted. This option keeps the cabinet temperature stable and allows heat dissipation faster. The servo drives for all axes are the most significant contributors to heat inside the electrical cabinet.

5-Axis Renishaw CalibrationThe calibration unit is a Renishaw model APCA45 with a modified spherical stylus. The device has a retractable cover and air purge to clear debris & dust during the activation process. It mounts to a swing arm controlled by a pneumatic rotary, so it is out of the way during regular operation and swings into the calibration position for calibration only.
