The lifting equipment has the characteristics that a processed part can be vertically lifted and transported through a high-automatic tooth meshing mode, and therefore the indirect beneficial effects of convenient processing is achieved.

Stay-in-place fascia forms and methods and equipment for installing thereof. A concrete form includes a vertical component and a horizontal component, the vertical component located substantially perpendicular to the horizontal component. Also, the form includes an interior surface, at least a portion of the interior surface providing a form for supporting uncured concrete; wherein the uncured concrete forms a concrete structural portion upon curing of the uncured concrete; and wherein the interior surface remains attached to the concrete structural portion after curing. The form may include inserts and compatible form attachments. Also, forms including recesses may be utilized to reduce the weight thereof. Lifting equipment and accessories may be utilized to lift the form from a form holder and set same in place. Forms contain the work area as soon as it is installed to minimize fall hazards and the time, costs, and downtime associated with installation of safety measures.

The invention discloses wheel brush lifting equipment of a car washer. The equipment comprises a bracket and a plurality of screws with the same structure, the bracket is arranged on the ground, a plurality of through holes of the same structure are formed in the bottom end of the bracket, one end of each screw is inserted into the corresponding through hole in the bottom end of the bracket, and the screws are connected to the ground in a screwed mode. The invention relates to the technical field of automobile cleaning devices. A wheel brush is driven through a lifting structure, so height adjustment is performed, and it is convenient to clean a vehicle body. The top of the vehicle body is cleaned through a cleaning structure; through a reciprocating structure, the wheel brush reciprocatesleft and right on the car roof for carrying out effective cleaning, so that dirt is prevented from remaining on the car roof; dirt cleaned by the spraying structure is flushed away, and damage to thevehicle body due to impact of high-pressure water is avoided; and by means of the design, power consumption is reduced, water sources, manpower and material resources can be saved, the labor intensity of workers is relieved, damage to the vehicle body is avoided, the service life of parts is prolonged, and effective cleaning can be achieved.

The invention relates to the technical field of power distribution cabinet installation, and discloses a novel pig farm power distribution cabinet installation device and a using method thereof. Lifting hooks used for being connected with slings in external lifting equipment are fixedly connected to the middle of shells on the two sides of a power distribution cabinet main body, the lifting hook is provided with a limiting mechanism used for limiting deflection of the sling corresponding to the side edge of the top of the power distribution cabinet main body, bases are further connected to thetwo sides of the power distribution cabinet main body through in-place guide mechanisms, and shock absorption mechanisms used for conducting buffer protection on the power distribution cabinet main body when the power distribution cabinet main body is lifted in place are further arranged in the middle of the upper surfaces of the bases. By means of the limiting mechanisms, the stability in the hoisting and moving process can be guaranteed, the swing amplitude of the rope can be reduced, it is guaranteed that the follow-up in-place guide mechanisms is smoothly conducted, and the in-place guidemechanisms and the shock absorption mechanisms are cooperatively matched, so that the stability of the electric cabinet main body during falling installation and the stability of the electric cabinetmain body after installation are guaranteed.

A mobile lifting apparatus, comprising at least one truck, provided with a first drive device comprising at least one internal combustion engine connected by power transmission means to one or more user devices of the truck hydraulically actuated, and at least one boom provided with a second drive device.

The invention discloses a coal mine underground rail wheel type high-altitude elevator, which relates to rail wheel type high-altitude lifting equipment in a coal mine underground roadway, and comprises a mining flat car, a shear fork lifting swing sliding frame, a double-piston-rod type sliding hydraulic cylinder, a working platform, a remote controller, an electric cabinet, a power supply, a hydraulic station and a claw type stabilizer, wherein the shear fork lifting, swinging and sliding frame is composed of a bottom base, a shear fork arm, a lifting hydraulic cylinder, a top base, a swinging and sliding seat, an ejector rod, a nut sleeve, a lead screw and a hydraulic motor; the claw type stabilizer is composed of a hydraulic cylinder, a left side fixing guide plate, a right side fixing guide plate, a rear connecting rod, a hinged guide pin shaft, a front connecting rod, a front clamping claw, a hinged fixing pin shaft and a rear clamping claw. The equipment can prevent the high-altitude elevator from rollover or overturning when the high-altitude elevator is in unbalance loading and located on a track of an inclined roadway, the operation platform is adjusted to be always kept in a horizontal state, meanwhile, the position of the operation platform in the width direction of the roadway is adjusted, the mechanization degree of installation of underground roadway top equipment and daily operation maintenance work is improved, and the working efficiency is improved. The labor intensity of operators is reduced, and the working efficiency is improved.

The invention discloses an aircraft landing gear lifting device and a lifting method thereof, and relates to the technical field of lifting equipment.
