A telescopic jib bracing unit for a mobile crane includes a holding frame which is embodied for fastening to the telescopic jib of the mobile crane and exhibits an open cross-section, the cross-sectional opening of which enables the jib to be retracted into the holding frame, and two bracing supports which are connected by the holding frame to form a structural unit. Two frame parts which form the open cross-section of the holding frame are coupled to each other via a coupling point such that they can be moved with respect to each other. A bracing unit transport system, a mobile crane and a fitting method are also provided.

A vehicle includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, and a stability system. The stability system includes a pair of front downriggers coupled to the chassis forward of the front axle and an outrigger assembly coupled to the chassis between the front axle and the rear axle. The outrigger assembly includes a pair of outriggers that are selectively extendable laterally outward at an angle relative to a horizontal.

A lifting system for a vehicle including a powered winch, a telescopic hoist, jib, or arm and an attachment means on the vehicle for allowing the hoist arm to be pivotally adjusted. The attachment means is provided as a mounting plate which is mounted beneath the vehicle. The mounting plate includes receiving sections that receive a bottom distal end of the telescopic hoist arm. The hoist arm then upwardly extends from the bottom of the mounting plate and is supported to the vehicle using straps. Furthermore, the winch is provided as an integral part of the vehicle which is then fed through to the hoist arm an received by a pulley member located on a distal top end of the hoist arm. The winch is then secured to an anchor which is adapted to receive a load to be transported by the lifting system.

A crane for lifting and transporting loads includes a handling element, for supporting and handling the loads, and a chassis for transferring the loads of the crane onto a support surface by a contact arranged in contact with the surface, such as wheels. A drive transmission, such as a drive wheel, moves the crane on the support surface. The drive transmission is capable of translating relative to the chassis to adjust the force exerted by the drive transmission upon the support surface. The crane includes a sensor for detecting the force exerted by the drive transmission upon the support surface; and a control unit configured for adjusting the position of the drive transmission relative to the chassis, based on the detection of the sensor.

To reduce the number of places where dimension control regarding an attachment position of a coupling portion to a structure is required. A first coupling portion includes a first pin receiving portion into which a coupling pin can be inserted, and a load transmitting portion integrally provided with the first pin receiving portion. A second coupling portion includes a second pin receiving portion into which the coupling pin can be inserted, and a load receiving portion integrally provided with the second pin receiving portion. The first pin receiving portion and the second pin receiving portion match with each other so as to detachably attach the coupling pin in a state where the load transmitting portion and the load receiving portion are in contact with each other.

A crane, in particular a pick and carry crane, may have a front chassis with front wheels and a back chassis with back wheels, the front chassis being articulated relative to the back chassis so that the crane can travel whilst carrying a load suspended from a boom. The back and front wheels have independent suspensions which are capable of connection to one another so that movement of a left wheel influences movement of a right wheel, thereby improving the handing of the crane, particularly over rough terrain.

A stabilizer leg device with a stabilizer leg to be moved down-wards from an object so as to stabilize the object by bearing through a foot plate (7) on the ground. The device comprises a first engagement member (20) arranged coaxially to a horizontal axis on a part (19) fixed in relation to the object, and a shaft (12) having a first end provided with a second engagement member (21) and an opposite second end arranged to be influenced by movement of a second stabilizer leg member in relation to a first stabilizer leg member to make the shaft slide along the stabilizer leg under extension and retraction of the stabilizer leg so as to cause pivoting of the stabilizer leg by a mutual engagement of said engagement members (20, 21). Members (16, 17) guiding the shaft are designed to automatically unlock and lock, respectively, the stabilizer leg with respect to possibility to pivot about said horizontal axis by passing a predetermined position by the second stabilizer leg member upon retraction and extension of the stabilizer leg.

A locking head assembly (210) for a telescoping boom (118) of a crane (110) includes a locking head (212) having a base (218), an operating plate (220) operably coupled to the base, one or more cylinder pins (222) and/or one or more section lock arms (226) movable in response to movement of the operating plate relative to the base. An actuator (214) is operably coupled to the operating plate and configured to move the operating plate relative to the base. The actuator includes a motor (234) and a drive arm (236). The motor is configured to drive the drive arm between a drive arm first position and a drive arm second position. A motion mitigator (216) is connected to the actuator and the locking head and includes a housing (238), a rod (240) movable relative to the housing, and a biasing device (242) disposed between the rod and the housing.

The focus of the present disclosure is on portable cranes and cantilevered base systems. In particular, portable cranes and cantilevered base systems which are lightweight, easy-to-operate, safe, inexpensive, and have extended reaches with high-load capacities would be advantageous for a variety of applications. A cantilevered support to a pivotable arm that is provided by the present disclosure provides advantages when compared to other portable cranes, such as the ability to: 1) extend an arm and reach of a crane, 2) increase a load that can be lifted or lowered, 3) operate a portable crane and cantilevered base system freestanding without attaching a base to a floor, surface, or bed of a vehicle, and 4) augment the structural capacity of a portable crane and cantilevered base with mechanical devices to support a variety of applications.

Provided is a method for clustering the data point groups of one or more measurement targets located in the same region from among the acquired data point groups. This method is provided with: acquiring a data point group in a region that contains a measurement target from above the measurement target by using a laser scanner; clustering the data point groups that correspond to the top surface of the measurement target as a planar cluster by using a data processing unit; extracting a reference planar cluster which is a reference for making a same-region determination; calculating the difference in height between the reference planar cluster and other planar clusters, and searching for planar clusters exhibiting a height difference within a prescribed threshold; selecting one planar cluster exhibiting a height difference within the prescribed threshold; detecting whether there is overlap between the reference planar cluster and the one planar cluster; and clustering the planar clusters as clusters in the same region when overlap is detected.
