Work machine
A hydraulic excavator (1) including a controller (21) having a load computing section (52) configured to compute a load of a work target material on the basis of thrust information about a boom cylinder (16) during the period when a front work implement (12) is performing a transporting operation of a work target material, the controller (21) further including: a velocity limiting value computing section (55) configured to compute a limiting value (Vlim) of a velocity of a boom cylinder (16) on the basis of posture information about the work implement (12) at a time of starting the transporting operation; a velocity command correction section (50) configured to correct a velocity command in such a manner that the velocity of the boom cylinder is equal to the limiting value (Vlim) when the velocity of the boom cylinder exceeds the limiting value and output the corrected velocity command; and a drive signal generation section (51) configured to generate and output a drive signal for the boom cylinder on the basis of the velocity command output from a velocity command correction section.
Zero-G lift assist device
Apparatuses, systems, and methods are disclosed for providing a zero-G condition to a part to assist in allowing an operator to weightlessly move a part and assist an operator in the installation of a part into an assembly. Present methods, systems, and apparatuses further provide a zero-G lift able to alter the lift velocity of a part, from first predetermined velocity to a second predetermined velocity.
Dynamic pallet dimensioning with forklift taring
Cargo objects, in a freight-related environment, are dynamically dimensioned while being held at a cargo-handling position of a vehicle. A three-dimensional model is obtained comprising points representing surfaces of the vehicle. Using the model, the position of a point of reference of a first wheel of the vehicle is obtained, as is the position of a split point relative to the position of the first wheel point of reference. A driving direction of the vehicle is obtained. A splitting plane is determined, which passes through the split point and is perpendicular to the driving direction. A three-dimensional model of the cargo is determined by subtracting, from the vehicle three-dimensional model, the points that are positioned on the side of the splitting plane opposite to the side of the splitting plane that make up the first wheel point of reference. The volume is then determined from the cargo three-dimensional model.
Vehicle collection bins and scale systems
This disclosure describes a collection bin for a waste collection vehicle. The collection bin includes a weighing system with a processor for measuring the weight of material collected from each waste container and associating this weight with appropriate data, such as the owner of the waste container.
System and method of calculating a payload weight
A system of calculating a payload weight, the system including: a first sensor configured to assist in determining an actuator load associated with a ram, the ram being connected to a lifting member; and a calibration module configured to retrieve a calibration factor based on movement of the ram, the calibration factor being applied to the actuator load to thereby provide an adjusted actuator load; wherein the payload weight is calculated based on the adjusted actuator load.
WORK VEHICLE, METHOD OF DETERMINING WEIGHT OF PAYLOAD, AND METHOD OF CALIBRATING A WEIGHT OF A PAYLOAD
A work vehicle, a method of determining a weight of a payload supported by a work tool mounted to an upper structure of a work vehicle, and a method of calibrating a weight of a payload supported by a work tool mounted to an upper structure of a work vehicle are provided. The work vehicle includes an undercarriage having a plurality of ground engaging members supporting the work vehicle, an upper structure rotatable relative to the undercarriage about a vertical axis, a rotation sensor configured to determine a rotation angle of the upper structure relative to the undercarriage, a work tool mounted to the upper structure and configured to support a payload, and a controller configured to determine a weight of the payload based at least partially on the rotation angle of the upper structure relative to the undercarriage.
Method and arrangement in a weighing system and a corresponding software product and material handling machine
The invention relates to a method in a weighing system, in which method the mass of the bundle is weighed and recorded during both loading % and unloading m.sub.i_p of the bundle, during loading, the total loading mass m.sub.K_kok_j is calculated from the mass m.sub.i_c of one or more bundles weighed during loading and corrected using a correction factor C.sub.j, the total unloading mass m.sub.p_kok_j is calculated from the mass m.sub.i_p of one or more bundles weighed during unloading, with the aid of the said total loading mass m.sub.K_COk_j and total unloading mass m.sub.p_kok_j, a new corrected value Cj+1 is calculated for the correction factor C.sub.j in order to adjust the weighing for the loading of the next load K.sub.j+1. The invention also relates to a corresponding software product, an arrangement, and a material-handling machine.
Flexible plate scale for platform load weighing
An AWP boom is coupled to a platform rotator through a novel load sensing linkage system which provides both structural support and load sensing capabilities of an attached platform support structure. The load sensing linkage system includes an upper flex plate and a lower flex plate and a single load cell for load sensing capabilities. The flex plates provide for stiffness in all directions except where necessary for load sensing.
VEHICLE WITH AERIAL WORK PLATFORM
