TECHNICAL FIELD

The invention relates to a gripping member adapted to be mounted on a crane arm having a movable gripping arm.

10 PRIOR ART

Knobs such as the gripper member of the invention are known to be used in the treatment of columns and masts, i.e. erection and lowering; especially for handling railroad poles, for example. Often, the crane arm is then 1 15 as part of a telescopic crane mounted as an accessory on a vehicle, such as a wheel loader. To extend the area of use of the crane for column and mast work, the gripping element can be replaced with a rack that allows a person to work at the top of a vertical column or mast. However, such • »· interchanges between the gripper and the cradle on the crane arm are time consuming. Besides, there is usually no natural parking space in the vehicle- 'v: * · * for the unit that is temporarily out of service, so this is often set to • · · · ·.'% · ... · ground.

SUMMARY OF THE INVENTION

25? It is therefore an object of the invention to provide a gripping means for solving such problems, that is, a time-consuming exchange and a stopper of a gripping means and a personal basket.

This is achieved by the special features set forth in the following claims.

According to an embodiment of the present invention, the movable gripping arm comprises, on its outer side, a fastener for a personal basket. Through this, the basket of persons can thus optionally be lifted along the crane by means of a gripping member. In this way, the gripper and the basket are connected to the crane arm in Saija, respectively. This way, the cradle can always be in place, supported by the crane arm. Thus, in the closed position, the gripping element always follows the cradle as a passive intermediate between the crane arm and body. Thus, the gripping member according to the invention, both when working in the personal rack 10 and also when parking the crane arm, can allow both units to remain attached to the crane arm at all times.

According to a preferred embodiment of the invention, the movable gripping arm is pivotally secured between a closed gripping position with the clip facing in the first direction and an open gripping position with the clip facing in the second direction. If the crane arm is normally mounted on one side of the longitudinal center axis of the vehicle, then the first and second directions may be selected so that the passenger body can be parked on the · · V. * side, and possibly in front of the vehicle. : ** · 20 widths, which is of great importance for moving the vehicle through obstacles-% * * '*: * · on steep public roads.

Fig. 2 shows the gripping member corresponding to Fig. 1 in the closed position, DETAILED DESCRIPTION OF THE APPLICATION EXAMPLE 5 As shown in Figs. 1 and 2, a gripper member of the invention generally designated by reference numeral 10 may be mounted on the crane arm 70.

The connection between the crane arm 70 and the engaging member 10 comprises a known type 10 plug connector having a male connector 72 on the crane arm 70 and a female connector 66 in the engaging member 10.

The gripper member 10 consists essentially of portions of a fixed gripper arm 12 and a movable gripper arm 60. In the example shown, the movable gripper arm 60 is pivotable; It is connected to the first end of the frame beam 14 of the fixed gripping arm 12 by means of a bearing bracket 44 with my pivoting lead 46.

The inner or opposite of the second pivot lever 56; the knurled end is connected through the joint 58 to the inner end of the movable gripping arm 60.

As shown in the drawing, by actuating actuator 24, using the mechanism 10 described above, movable gripper arm 60 of gripper 10 can be rotated 180 ° from fully open grip position - stop-position shown in Figure 1 - with clamp 64 facing fully rearwardly in the closed position in which the bracket is oriented in the forward position A which is the same as the longitudinal axis of the arm 70 of the crane 5 '15.

According to the invention, the movable gripping arm 60 has on its outer side a bracket 64 for the ID card 80 shown in dashed lines, comprising a single swivel-mounted body unit 84. The bracket 64 is preferably a male of a similar plug connector. a connector like the one that connects the grab member • · • · • "10 to the crane arm 70.

When the tag is used in the fully engaging position of the grip member 10, in the embodiment shown in Fig. 2, the movable grip 60 is locked by a locking mechanism.

The locking mechanism comprises an actuator, in this case a hydraulic cylinder 32, the first end of which is connected via a joint 34 to a movable retaining arm 60, and the other end of which is connected by a joint 36 to the central part of the locking arm 38. The first end of the locking hook 38, in turn, is connected via the joint 40 to the movable gripping arm 60, and at its other end has a locking groove 43, 10 which lockingly engages the hook pin 42 in the frame beam 14 of the gripping arm 12.

Within the scope of the following claims, many different solutions may be contemplated for those skilled in the art. Thus, the crane arm 70 and the gripping element: · 15 10 can be dimensioned so that the accessory 80 can be used in the height) ·
