A lifting device and a washing machine to resolve difficulty moving a washing machine. The device includes a driving device, a connection rod, a first lever, a second lever and support legs, where the driving device is on the bottom of a washing machine body; the support legs are arranged at the bottom of the body; the driving device is connected to a first end of the first lever and to a first end of the second lever in a driving manner, by the connection rod; a second end of the first lever is connected to one of the support legs, and a pivoting end of the first lever is connected to the washing machine body; and a second end of the second lever is connected to one of the support legs, and a pivoting end of the second lever is connected to the washing machine body.

A fully electric lift device includes a base assembly, a lift assembly, a platform assembly, tractive elements, an energy storage device, and a control system. The lift assembly is coupled with the base assembly and is driven by an electric linear actuator for a lifting function. The platform assembly is positioned at a top of the lift assembly and can be raised or lowered as the lift assembly performs the lifting function. The tractive elements are rotatably coupled with the base assembly and can be driven by an electric wheel motor to perform a driving function. The control system includes a controller that operates the electric wheel motor and the electric linear actuator to perform the driving function and the lifting function using power drawn from the energy storage device. The lift assembly and the tractive elements use only electrical energy to perform the lifting and driving functions.

A crank assembly for displacing a load includes a motor and a displacement arm assembly. The motor includes a rotatable output shaft that defines a rotation axis. The displacement arm assembly includes a swingable crank arm and a support roller bearing. The swingable crank arm is coupled to the output shaft to swing about the rotation axis when the output shaft rotates. The swingable crank arm defines a pivot end adjacent the rotation axis and an opposite displacement end. The support roller bearing is rotatably supported on the swingable crank arm proximate the displacement end. The support roller bearing is configured to engage the load. The support roller bearing defines a bearing axis, which is substantially parallel to and offset from the rotation axis.

A pile-side lateral static load device includes a jack system, a liftable jack cart, a loading jack fixing system, and a loading system. The jack system includes a jack body. The jack system is installed on the liftable jack cart through the loading jack fixing system. The loading system is installed on the loading jack fixing system, and the loading system includes counter-pressure loading systems and counter-tension loading systems. The pile-side lateral static load device has a simple structure, is convenient to install and operate, and can complete lateral loading and in-situ tests under different pile diameters, different tonnages and different precisions, so as to facilitate a simulation test of in-situ lateral loading of a pile.

Disclosed is a lifting robot that includes a housing and a tray. The housing includes a side wall formed by a plurality of enclosing side panels, a projection of the side wall on a horizontal plane is a regular polygon, and at least one of the plurality of side panels is provided with a connection device for connecting to a side panel of another lifting robot. Further disclosed is a robot system including a plurality of the lifting robot described above.

A method and apparatus for transporting heavy machinery, equipment or other heavy loads from one location to another, whereby the apparatus may be constructed as a walking machine including a plurality of lifting assemblies operative to lift the load above the supporting surface and then move the load relative to the supporting surface by transporting the load via rollers or tracks in the walking machines. In one example, the lifting assemblies are provided with separate longitudinal and lateral drive mechanisms independently operative for translating the load in either or both longitudinal and lateral directions.
