    • A hydraulic crane comprising:
      - a rotatable column (7);
      - a crane boom system (10) comprising two or more liftable and lowerable crane booms (11, 13); and
      - an electronic control device (25), which is configured to prevent an execution of crane boom movements that would make the lifting moment of the crane exceed the maximum allowed lifting moment of the crane, and to continuously establish position information as to the prevailing position of the load suspension point (P) of the crane boom system.
      When the lifting moment of the crane has reached a limit value at a given level below the maximum allowed lifting moment, the electronic control device is configured to prevent the execution of any combination of crane boom movements that would increase the horizontal distance between the load suspension point and said vertical axis of rotation and at the same time allow the execution of any combination of crane boom movements that keeps said horizontal distance unchanged or reduces said horizontal distance.
    • 一种液压起重机,包括: - 可旋转柱(7); - 起重机悬臂系统(10),其包括两个或更多个可升降的起重机悬臂(11,13); 和 - 电子控制装置(25),该电子控制装置构造成防止起重机吊杆运动的执行,该起重机吊杆运动将使起重机的起重力矩超过起重机的最大允许起吊力矩,并且持续建立关于主要起重机的位置信息 起重臂系统的负载悬挂点(P)的位置。 当起重机的起重力矩已经达到低于最大允许起吊力矩的给定水平的极限值时,电子控制装置被配置成防止起重机悬臂运动的任何组合的执行,这将增加负载悬架之间的水平距离 点和所述垂直旋转轴线,并且同时允许执行起重机吊臂移动的任何组合,以保持所述水平距离不变或减小所述水平距离。

    • A pole arrangement comprising: —a pole (2) with a tubular external wall (4) of sheet metal; —a foundation (5) with a cavity (7) for receiving a lower section (8) of the external wall (4) of the pole; —a wedge element (6) for securing the pole in the cavity by wedging; and —a reinforcement element (23) mounted to a part of the section (8) of the external wall (4) of the pole received in the cavity, in order to counteract buckling of this part. The wedge element bears against the external wall of the pole through supporting projections, wherein there are free spaces between the supporting projections in order to allow parts of the external wall of the pole to be pressed into some of these spaces when the external is buckled in connection with a collision. The reinforcement element (23) is arranged at an axial distance from an upper opening (9) of the cavity in order to allow, in connection with a collision against the pole, buckling of the part of the external wall of the pole located between the reinforcement element and the opening of the cavity.
    • 一种杆装置,包括: - 具有金属板的管状外壁(4)的杆(2); - 具有用于容纳外壁(4)的下部(8)的空腔(7)的基座(5) 的杆; - 楔形元件(6),用于通过楔入将杆固定在空腔中; 以及 - 安装到容纳在空腔中的极的外壁(4)的部分(8)的一部分的加强元件(23),以抵消该部分的弯曲。 楔形元件通过支撑突起抵靠杆的外壁,其中在支撑突起之间存在自由空间,以便当外部是外部的时候允许杆的外壁的一部分被压入这些空间中的一些 与碰撞有关。 加强元件(23)被布置在与空腔的上开口(9)的轴向距离处,以便在与极的碰撞的情况下允许位于位于该杆之间的杆的外壁的部分的弯曲 加强元件和腔体的开口。

    • A heating installation comprising : - a first circuit (C1); - a second circuit (C2); - a first heat pump (4) for heating the medium in the first circuit; - a first heat exchanger (10) arranged in the second circuit (C2) and connected between a condenser (4b) and an expansion valve (4d) of the first heat pump; - a second heat pump (11) arranged for heating a medium by absorbing heat energy from the medium in the second circuit; and - a second heat exchanger (12) and a third heat exchanger (14) for transferring heat from the medium in the second circuit to water in a water supply line (13). The second heat exchanger (12) is connected to the water supply line upstream of the third heat exchanger (14) in order to allow the second heat exchanger to preheat the tap hot-water in a first step and the third heat exchanger to preheat the tap hot-water in a subsequent second step.
