Autoquip TITAN UPENDER - Manual (Page 17)

1. Upenders have maximum lifting capacity ratings (See the “Specifications” section).
The safety relief valve has been factory set to open at a point slightly above the
rated load and allows the oil to bypass into the reservoir. The safety relief valve
should not be adjusted for any reason as it could cause the motor to
prematurely burn out. Applying loads exceeding the rated capacity of the Upender
may result in excessive wear and damage.
2. This type of Upender is designed primarily for in-plant applications and is furnished
with a constant pressure foot switch or pushbutton controls. Actuating the "TILT" or
“TILT RETURN” buttons will cause oil to enter the extending cylinders and oil to be
dumped to a tank from the retracting cylinders, thus causing the Upender platform to
begin the tilt travel.
3. The Upender is designed to tilt a full ninety degrees. As the platform tilts it will reach
a point just past mid-travel where a limit switch will be tripped, the motor will be
turned off, and the Upender platform will be allowed to travel the remaining distance
under force of gravity. During this last 35-40 degrees of tilt the oil interflows from the
retracting cylinders to the extending cylinders and the tilt speed is regulated by fixed
flow controls.
4. At any point during the complete tilting sequence – whether tilting under power or
under gravity – removal of the operators’ foot or hand from the “TILT” or TILT
RETURN” switch or button interrupts the tilt sequence by causing all oil flow to or
from any of the cylinders to cease. This will immediately stop movement of the
Upender and “lock” the platform into its current position.
CAUTION!
Do not continue to activate the "TILT" button if the Upender is not raising
or if it has reached the fully tilted position. To do so may result in
permanent damage to the Upender.
