• the device additionally comprises locking members 8 for attaching the arm to the tuming member.
• the arm has lenghtwise grooves, on which the locking members locate.
• the mounting member 2 is a movable member on the beam 1 attached to its locking member beneath the beam with locking pins 14 and is tightenable firmly against the beam with the help ofthe locking pins and the locking member.
• the mounting member is round shaped and the turning member is lockable with the help of the locking members in desired position relative to the mounting member. This kind of mounting member is movable along the beam to the desired point with respect to the vehicle frame, which thus enables an easy positioning ofthe tool.
• the device is attachable to the lenghtwise or crosswise beam ofthe straightening system.
• the fastener 15, to which the tool 4 is attached turnably, is placed at the end ofthe arm 6.
• the tool is lockable with the help of locking members located on the sides ofthe fastener in desired position.
• the vehicle is attached to the straightening system with two devices according to the invention.
• the constmction ofthe device corresponds to one shown in Fig. 1, but another arm 7 is attached to the fastener 15 located at the end ofthe arm 6, the said arm extending at right angles with respect to the arm 6, in other words it is in vertical direction with the respect to the straightening system and the beam.
• the locking nuts function as locking members 12 ofthe arm.
• the arm 7 is a bar and is tumable about its axle i.e. is rotatable round the fastener 15.
• Another fastener 16 is attached to the end ofthe arm 7 and a third arm 13 is attached to this fastener.
• the fastener 16 situates crosswise at the end ofthe arm 7 and thus the arm 13 is at right angles with respect to the other arm 7.
• arm 13 is a bar and rotatable with respect to its fasteners.
• the device comprises adjustment and mounting members to adjust and lock the arm member with respect to fastener 16.
• a third fastener 17 is located in the end ofthe arm 13, to which an earlier-known clamping member 4 is attached, said clamping member being attachable to the frame ofthe vehicle 12.
• the clamping member 4 is attached rotatably to the fastener 17.
• the clamping member is attachable to extend to either downward or upward from the fastener, and thus the device is also adjustable in this way and the clamping member can be set to the desired place.
