  • Page 10: Description

    Description Design and Operating Principle These manually operated hydraulic, combined hydraulic / pneumatic or pneumatic pit jack / axle and transmission jacks are lifting devices for lifting vehicles and power trains. The pit jacks can be moved in the longitudinal and transverse direction on a chassis, the axle and transmission jack using a chassis running on the ground using rollers.

  • Page 16 Slide the chassis carriers sideways onto the lift rollers (Caution: Danger of tip- ping!) and secure with lashing straps. At least one second person must be called in to support the assembly work, and if necessary other persons must also be called in.
  • Page 17 Fasten one side part with round sling, lift it by crane and insert it laterally with the square spigots into the chassis carriers as far as it will go. At least one second per- son must be called in to support the assembly work, and if necessary other per- sons must also be called in.
  • Page 18 Align the chassis with the one already mounted side part load symmetrically on the lift, i.e. the centre-of-gravity (not the centre!) should be aligned centrally above the lift. Attention: Danger of tipping! At least one second person must be called in to support the assembly work, and if necessary other persons must also be called in.
  • Page 19 Repeat step 6 with second side panel. After inserting the second side panel, repo- sition the chassis centrally on the lift. At least one second person must be called in to support the assembly work, and if necessary other persons must also be called in.
  • Page 20 Now align the lift centrally in the chassis and secure it against slipping. Two lashing straps are recommended, which are guided through the handle openings in the carriers and enclose the lift in opposite directions. At least one second per- son must be called in to support the assembly work, and if necessary other per- sons must also be called in.
  • Page 21 Attach the hoist diagonally to two jack rollers with a round sling. Then lift the jack incl. chassis by crane and lower it centrally into the pit. The side panels must be pushed in as far as they will go as described in steps 6 and 8.
  • Page 22 Align the jack in the L-profile or in the U-profile depending on the installation situation. If necessary, the chassis can be tilted for this purpose if the securing described in step 9 has been carried out correctly using lashing straps. BA550401-en...
  • Page 23 Loosen the M12 screws on one side panel until the washer can be turned freely. Now pull out the side panel until the collars of the chassis rollers are in contact with the pit profile. Repeat the process with the second side panel. Make sure that both side pa- nels are extended to the same extent so that the carriers are positioned sym- metrically in the middle between the side panels.
  • Page 24 Tighten the M12 screws on both side panels to a tightening torque of 85 ±5 Nm. Check the central alignment of the chassis. Remove the round slings and push the jack through the entire working pit. At the widest point of the working pit, the clearance between the roller collar and the pit profile may be 5 mm on both sides.

  • Page 25: Assembly Of The Carriage Version Above 20 T

    Assembly of the Carriage Version above 20 t The carriages for loads above 20 t are welded to size, i.e. no side panels can be moved or carriers removed. Observe the assembly and disassembly procedure described in section “Assembly of the Carriage Version up to 16.5 t”.
  • Page 26 c. Use a suitable hoist to lift the carriage and lower it above the lift until the head plate is approx. 90 mm above the running surface of the carriage. Then mount the jack axles incl. rollers (see illustration). Set the tightening torque to 50 ±5 Nm. d.

  • Page 28: Raising And Lowering

    Raising and Lowering Speed lift without load By activating the automatic or manual speed control (B or C) the ram moves up to engage the load (axle, gearbox). Depending on the air pressure and the lift achieved, the ram rises a little further after releasing the button. Lifting the load The load is lifted by activating the automatic or manual / foot operated lifting control (D or E).

  • Page 32: Refilling With Hydraulic Fluid

    Refilling with Hydraulic Fluid Before checking and topping up the fluid level, make sure the piston rod is fully retracted and the jack is disconnected from the air and power supply. The fluid level must be between the two notches on the screwed-in dipstick. If the dipstick has only one notch, this indicates the maximum fluid level and the lower end of the dipstick the minimum fluid level.
