KSHS Series Safety Drop Stop "SDS" Servo Hoist (Patent No. 10,099,904)
Knight Global’ s “Next Generation Servo Hoist” includes the patent pending “Safety Drop Stop” “SDS” feature, which makes it the safest intelligent hoist in the world. This new revelation will change the entire hoist industry with Knight Global in the forefront. Redundant chains, one carrying the load, and the second travels along for safety.

Knight Global’ s KSHS “Next Generation Servo Hoist” Series has added features to its Intelligent Assist Device (IAD) that improves an operator to precisely locate or float a load in the "Z" direction (vertical axis) with speed, precision, quality and unmatched reliability. Knight's KSHS “Next Generation Servo Hoist” Series allows for many application solutions due to its various programmable features, and unlimited I/O. The KSHS Series enables an operator to simply grasp the handle and move the load, eliminating push buttons. Traditional hoists require the operator to push buttons in order to initiate movement, the built-in sensor allows a natural ergonomic motion.

Knight's Servo Hoist technology becomes an extension of an operator's natural movements and greatly improves accuracy, responsiveness and repeatability; which increases overall safety, productivity and quality. The inherent benefits include: eliminating wasted motions, reduced reaction times, and minimal effects of inertia with heavy loads. Providing our customers with endless solutions to their ergonomic applications needs.

KSHS Series Servo Hoist Control Configurations
When Selecting a Knight Servo Control System there are many factors to determine before selecting the appropriate configuration. To assist in determining the correct configuration for your application you will need to Print, Fill-out and Submit the configuration sheet below to Knight's Estimating Department. If you need any assistance or need more information, Contact our Servo Department.
Determining your Application Process
1.) System configuration - The KSH Series comes as a complete system with the option of an inline handle or a
      remote handle. One or the other comes with the system, not both.
2.) Lifting Capacity - Include your fixture, and part weight when determining a size.
3.) System Style – Single chain
4.) Coil Cable Length:
          a. Rail height – Know your hang point, from the bottom of the rail to the load hang point on a servo can be as
               tall as 4 ft., depending on your system configuration.
          b. Determine your pick-up and drop-off heights, this is very important and can affect your stack-up and rail
          c. Use the application drawing to determine your stack up.
          d. Choose your coil cable.
5.) Trolley - determine your hang point (this can not be a single point) and choose your trolley. If you have a
      trolley already, an EBD1127 adaptor plate will be provided at no extra charge.
6.) Hoist Control Set-up - Determine how your going to control your up/ down movement, and which configuration
      best fits the application; keeping the following in mind.
          a. Choosing the Inline Handle:
                  • Can the operator reach the handle in the upmost position?
                  • Will the operator be safe using the inline handle with being so close to the load?
          b. Can the operator always reach the run-stop button?
          c. Be sure you identify any additional cables when choosing your configuration.
                   • The LMM to the OCI
                   • The fixture handle to the OCI
7.) Plant Power – Servo systems operate on 230VAC 1phase. If the plant that this is being installed in only has
      480VAC, you will need to order one of our 480VAC/ 240VAC transformer disconnect options.
