摘要： Provided is a lifting device with a force-absorbing base to which a boom with hoisting cable for lifting a load in substantially vertical direction is tiltably connected. The lifting device is provided with an auxiliary device for counteracting tipover of the boom in the case of sudden loss of load. The auxiliary device is connected to the base of the lifting device, provides a contact surface which is in permanent contact with a contact surface of the boom or comes into contact therewith in the case of tipover, and further comprises a drive and control system which is configured to stop the boom movement when a predetermined force between the contact surfaces is exceeded as a result of the boom tipping over. The described auxiliary device can take an autonomous form and can be arranged on a lifting device.

摘要： A back stop for a crane which eliminates operator's discomfort and adverse effects on surrounding environment due to generation of abnormal noise and enables greasing work to be facilitated. A back stop includes an outer casing having a base end portion turnably connected to a boom or a crane main body and an opening portion opened in the outer casing front end portion; an inner casing having a base end portion turnably connected to the crane main body or the boom and having a front end portion side slidably fitted into the outer case through the opening portion; and a greasing tube arranged in the outer casing or the inner casing. An inlet of the greasing tube is arranged outside of the outer casing or outside of the inner casing on the base end portion side on which the greasing tube is arranged. A discharge port of the greasing tube is attached to a front end portion of the inner casing.

摘要： A crane has a rotatable body with a vertically pivotal boom connected thereto. An energy absorbing stop unit is mounted in a fixed position on the body, and a guide sleeve is pivotally mounted on the body adjacent the stop unit. A stop rod is pivotally connected to the boom at a point between the ends of the boom for vertical swinging movement, and the rod is maintained in the guide sleeve in every position of the boom. The guide sleeve is pivoted by the stop rod into alignment with the stop unit at the extreme upper position of the boom, and, at that position of the boom, the stop rod extends through the guide sleeve into engagement with the stop unit.

摘要： A crane includes a luffing jib and a lifting cylinder having a cylinder body and a movable rod hinged on the jib to displace the jib in lifting motion and in lowering motion, and a locking device adapted to cooperate with the lifting cylinder to mechanically lock the rod in a deployed holding position and block the jib in a raised holding configuration. The crane further includes a spacer hinged on the jib and supporting a stop, the spacer pivotable between a release position in which the spacer is shifted, allowing the movable rod to be freely displaced, and a locking position in which the spacer is folded so that the stop is capable of abutting on a bearing surface in a ball jointed connection with the cylinder body, to fixedly hold the movable rod in the deployed holding position.

摘要： A gravity actuated crane stop for a crane is disclosed. The gravity actuated crane stop has a first connector at a first end configured to couple to a first crane member and an interface at a second end configured to interface with a second crane member. A gravity actuated mechanism is disposed on the body and has a first configuration in which gravity actuated mechanism disables the interface, and a second configuration in which the gravity actuated mechanism does not disable the interface. The gravity actuated mechanism is automatically changeable from the first configuration to the second configuration as the body is moved from a first orientation relative to a horizontal plane to a second orientation relative to the horizontal plane.

摘要： Fall-back prevention press of a crane in the form of a gas pressure cylinder, with a piston rod engaging in a cylinder space of the gas pressure cylinder configured as piston-type accumulator, with gas in the bottom space of the cylinder being in exchange with the gas in the piston rod and the ring space in surrounding relationship to the piston rod. A seal arrangement in a rod guide of the cylinder seals the piston rod against the cylinder. The seal arrangement includes a lubricant groove which extends around the rod guide and via which the piston rod is lubricated on the outside. The lubricant is acted upon by gas pressure prevailing in the cylinder with interposition of a pressure transmitter.
