GENERAL OPERATION:
Extension springs are attached to the scissors leg assembly. The springs are
arranged to extend as the platform height decreases. As the table is loaded
(platform height decreases) the springs extend, thus increasing the load
carrying capacity of the springs and subsequently counter balancing the load
on the table. By changing the length of the spring, the amount of load to be
counterbalanced can be varied.
ADJUSTMENT PROCEDURES:
1) Determine the approximate total weight of load the weight of the load per
layer being loaded/unloaded. The platform will travel consistently if the load
per layer is at least 10% of the total load. (ie 500 lbs. total load = 50 lbs. per
layer) If your load is less than 10% the platform may into have the same
distance travel per layer for each layer loaded/unload. As with the adjustment,
the best way to establish this is by trial and error.
2) Locate the spring assembly (PT# 01646001) bolt head. This is located on
the cart frame below the push handle.
3) With the full load on the platform (WARNING! Do Not Exceed the Rated
Capacity of the Unit), adjust the spring assembly bolts (CAUTION! Always
Equally Turn Each Bolt) until the platform is just touching the lowered height
stops. This can be checkered by pushing down on the load or lightly lifting the
load (Be Sure NOT to have Hands Under Platform). Rotate the bolts
clockwise to increase the load carrying capacity and counterclockwise to
decrease the load carrying capacity of the springs. This should provide an
even travel per layer of load. Repeat this procedure for each load change.
NOTE: The table height can be adjusted within the full travel by adjusting the
springs to limit or increase the table travel.
