Genie ST-25: attachment, load and offset load center
Prepare the material lift with the actual load-center position as well as weight.
Identification and application
Genie’s Super Tower ST-25 is a manually winched material lift, distinct from a personnel platform. Reference: Operator’s Manual 32950, first edition, seventh printing. Check that the manual applies to the unit’s serial number and configuration before use.
The proposal must distinguish positioning a load during setup from the need to support it during the event. Each option is assessed with its equipment, attachment, operating space and audience/crew circulation. The responsible team checks that the system and its use suit the project before defining the installation.
Prepare the proposal
- Identify nameplate, serial number, load attachment and fork orientation, with inspection records. Do not select solely by catalog maximum or the ST-25 name.
- Prepare dimensions, weight, center of gravity and load securement. The manual measures load center from the front of the carriage; a long or offset load requires comparison of its actual position with the applicable chart.
- The trained and authorized operator must review the equipment, surface, operating area and use conditions, and perform the inspections and tests required by the unit’s manual before lifting.
Questions and alternatives
Can a light load sit at the fork tips?
Weight alone does not decide. Provide load center, attachment and dimensions to check limits and permitted position. We can assess another documented attachment or layout without improvised fork extensions.
Does maximum height apply to every attachment?
Attachment configuration and orientation change the case. Describe the required position and actual assembly rather than transferring another model or configuration’s figure.
Do two lifts automatically double capacity?
No. Distribution, method and loads at each support need assessment. A quote can compare alternatives, but dividing weight by machine count does not approve the operation.
Can it lift a person to adjust a light?
No. The ST-25 is for materials, not for lifting people. If someone needs to work at height, assess an authorized access method and its use conditions separately. Do not build a personnel platform on the forks.
