1 J.A. Becker & Söhne SL Skanska Stockholm -Fredriksdahl Hydraulic 3-Ram Lifts for buses -Stockholm

2 Project Bus-Depot Fredriksdahl 11 x Hydraulic 3-ram lifts - in telecopic execution- Exactly adjusted to SL vehicle fleet -all 3 rams in moveable execution- Head pieces fully recessed (equal with floor level) -rams can be lowered in recession in every position- -rams can be moved lengthwise in lowest position- Pneumatic second floor fill in parts -recessions are closed at all times- -no gaps safe working environment-

3 Main components Lifting unit Telescopic piston - honed and chromium plated surface- Proximity switch Head piece Safety locking bars with a hinge made out of solid material Locking position at every 100 mm - Mandatory within the EU - 2 pressure springs (concealed) Latch Position safety bar Highest possible safety due to two different and independent systems Controlled hydraulic unlocking Hydraulic circuit with non-return valve and mechanical locking

4 Main components Lifting unit Easy to maintain and repair through direct accessibility to ram sealings and hydraulic pump unit All components easily accessible from above Emergency-lowering accessibly from above Manual emergency lowering accessibly from above in case of disturbance (e.g. power failure) 4

5 Main components Lifting unit Motor, pump unit and valve block mounted inside a completely closed oil tank. Electronic synchronism device also assembled inside the oil tank Valve blocks directly flanged to cylinder No hydraulic tubes No hydraulic pipes No hydraulic couplings Valve block directly flange at cylinder Motor In case of any leakage, oil flows into the Oil tank! Pump 5

6 Main components Lifting unit A potentiometer is mounted within the closed oil-tank. By measuring the oil-level with a float switch, the exact hight-level of the ram can be calculated via the PLC As the oil-level of all three rams are steadily monitored, synchronisation-accuracy within 40 mm is assured through black-white synchronisation

7 Main components Cover Head pieces in fully recessed execution Best possible solution for low buses (e.g. low-floor buses with broken air suspension) Reduced set-up times as rams can be positioned in lowest position (e.g. through AWBP) - Lifting units do not have to be raised first In raised position, all gaps are closed through pneumatic second floor fill-in-parts 7

8 Main components Cover/Second floor In raised position, all gaps are closed through pneumatic second floor fill-in-parts 2 x pneumatic cylinders (piston diameter 63 mm) are mounted underneath the head-plate of the lifting unit A steel-plate is mounted on top the cylinders Air (8 bar) has to be provided by customer to the point where the electric-control box is placed By pressing the button lift the pneumatic-valve is activated, Pneumatic piston moves out all gaps are closed 8 While lowering the cylinder, at a certain height (approx + 50 mm), the pneumatic valve closes the head piece and second floor lower in recessesion

9 Main components Cover aluminum hollow sections connected with reinforced thermoplastic connecting parts extremely corrosion-resistant resistant to saline solution (road salt) resistant to fuel, oil, weak acid and weak leach capacity up to 5 to wheel load for inflated tires capacity up to 3 to wheel load for full-cushion tires (fork lift) 9 spare parts easy to replace no hardware or glue needed

10 Main components Cover Delivery Installation Step Installation Step 2 Ready- to- operate

11 Main components Cover Moving-range mm Installation depth mm Alu-segment-cover hanged in loop 11

12 Supports for low-platform buses Every piston is equipped with a head pieces which can be fully lowered in recession Measures of the head piece: mm x 260 mm x 70 mm Additional supports for buses are inclueded in the scope of delivery 12

13 Main components Control unit Red/green light Remote control with 15 m cable Reset button Emergency operation Horn Main switch LED failure indication AWBP -Selection switch (call vehicle) -Keyswitch (store position) -Vehicle list Reset

14 Options Red/green light To assure that every lifting unit is in lowest position before driving on/ off the lift it is equipped with redgreen light indicators. Automatic Wheel Base Positioning All three rams are equipped with a proximity switch. Only if all rams are located in lowest position, the indicator switches from red to green. The drive on /off is clearly signalled. Proximity switch All three rams are equipped with a rope-length sensor (sensoring the moving range) To reduce set-up times, up to 16 axles-distance (=bus types) can be stored Easy selection and recall of stored position by switch or display (optional)
