SLT-26 Lifting Unit

General:

• General purpose lifting unit that can either retract into the ground or be surface mounted
• Self-erecting tower rises to any height up to 100 feet from the base in minutes, at the push of a button
• Tower core width 26 inches
• Payload to 2,500 lbs. or more depending upon height requirement
• High wind sail capability

Tower Construction and Performance:

• Tower is comprised of special aluminum alloy extrusions using rivet and bolt construction.
• Tower is raised using a rack and pinion drive powered by a three-hp, three-phase, 480- volt, precision gear motor.
• Electrically operated mechanical brake secures the tower when the motor is not operating or when electrical power is shut off.
• Gear motor is controlled by an inverter, which provides a slow start and stop, and very accurate vertical positioning.
• Tower is capable of lifting 1,500 lbs. to 80 feet. Lifting capacity is higher at lower heights and varies with specific applications.
• In the down position, the tower is stowed in three bales that are approximately 84 inches high and 100 inches wide.
• Tower has high torsional rigidity so that objects located on the top can be rotated when the tower is extended to full height.
• All moving parts are enclosed by guards to protect employees at ground level while the tower is raised or lowered.
• Powered tilt and rotating features can be added to manipulate customer equipment which may be mounted on top of the tower.
• Tower is secured to an appropriate foundation by three bolts.
• Tower is protected by US patent #4,920,710, as well as patents in other countries.

Ground or Surface Storage Structure:

• Underground storage vaults can be provided based upon customer requirements. These can include retractable cavity guards and vault coverings.
• Above-ground storage vaults can be provided based upon customer requirements.

Customization and Options:
We would be pleased to discuss your specific requirements and options available.
