Specifications General The general specifications are also printed on the type plate on the mobile column lift. Table 3.1 Specifications Model ST 1075-FBF Lifting capacity 16,500 lbs Pressure relief valve 3,800 psi (sealed with plastic cap ex- works) Maximum lifting height 69"...
Specifications Lifting capacity Table 3.1 for specifications of the maximum lifting capacity. The overpressure safeguard in the hydraulic unit has been preset so that the lift can never raise more than the specified weight +10%. The design is calculated for a maximum load of 16,500 lbs on any one column. Lifting system This mobile column lift is an electrically driven hydraulic column lift for lifting heavy vehicles.
The columns are coupled together by an identification procedure (with an ID key). The control signals that ensure synchronised movement of the columns, are transmitted through the air. Control system The control system on the columns ensures that raising and lowering of the column lifts is simultaneous and synchronised, independent of the load distribution on the columns.
Specifications Column, lifting cylinder and guide block The column and lifting cylinder together form the most important part of the mobile column lift. A guide block with rollers is located within the U-shaped profile of the column. The rollers enable the guide block to move up and down the entire length of the column.
Installation Unpacking and setup Proceed as described below when unpacking and setting up each column. Warning Only use proper lifting equipment to move the column lift. Lift the column only at the points intended for this. Failure to relocate the column lift in the right manner can cause damage to the column lift and/or personal injury.
