An electrical track lighting system. The track lighting system includes a bendable track that includes a foamed adhesive strip on the upper surface separating two conductor rails. The track is cut to length and secured to the desired surface by the adhesive strip. Light fixtures having spring clip members with electrical contact surfaces engage onto the upper surface conductor rails of the track. Low voltage power is supplied to the track from an adhesive mounted transformer/dimmer switch through an adhesive backed power strip with adjustable angle snap connector.

Off-site factory built structure employs a chassis including two interior longitudinal beam members joined at their ends to a perimeter structure. A floor system is integrated within the chassis perimeter. A ledger member is fixed to the inner surface of each longitudinal perimeter member so that a top surface lies in a plane coincident with top surfaces of the interior longitudinal beams. Lateral members are coupled to the tops of the interior longitudinal beams and to the top of the ledger members. The lateral members include secondary stiffening members such as C-channel members, metal Z-channel members, or other metal members of similar structural capacity, spaced apart from each other by a maximum distance S, related to the width of the floor system W, by the equation:

S 12−½W.

The invention relates to a tool which is used for dismounting a plum blossom contact for switching in a high voltage electrical product, comprising a retaining base, top plates and an adjusting rod; the retaining base is provided with a centre hole, the adjusting rod penetrates through the centre hole and is extended out of the retaining base and is movably arranged with the retaining base, a plurality of the top plates are circumferentially and movably arranged on the end surface of the retaining base by taking the adjusting rod as the axle to form a top plate group, an elastic reset device is circumferentially arranged on the top plate group, an inclined surface is arranged at one side of top plate, which is toward to the axle, the inclined surfaces on a plurality of top plates which form the top plate group circumferentially form a cone-shaped adjusting cavity, the end part of the adjusting rod is arranged in the cone-shaped adjusting cavity, and the diameter of the end part of the adjusting rod is more than the diameter of the top part of the cone-shaped adjusting cavity. The tool has the advantages that: the plum blossom contact is dismounted conveniently and quickly, the plum blossom contact can be effectively protected from not being damaged, the passing percent of the product is increased, the manufacturing efficiency is increased and the potential safety hazard is eliminated.

The invention relates to a solar tracker for photovoltaic panels, having a system for orienting same along two perpendicular axes and including a supporting platform provided with motorised wheels and at least two solar panel holders. The solar tracker platform comprises straight lattice griders having suitable dimensions for conventional transport, a central shaft which receives the horizontal stresses and horizontal bracing elements which prevent horizontal deformations and render the assembly vertically flexible. The solar panel holders are coupled to the platform such that they can rotate about a horizontal axis and said holders include a double guide system, provided on the frame and the purlins, in order to simplfy mounting operations.

The invention provides road construction equipment, and belongs to the field of road construction. The equipment comprises a machine body, and the machine body comprises a machine box; wheels are arranged at the bottom of the machine box, a movable frame is arranged on one side of the machine box, and the movable frame is hinged to the machine box; a supporting sleeve is arranged at the end of themovable frame; the supporting sleeve is arranged in the vertical direction. During road construction, a warning column with an isolation warning function can be installed through the equipment so that the warning column can be quickly and safely installed on a construction site to achieve a warning effect on passing vehicles. The equipment can be widely applied to urban road construction, rural road construction and mountainous road construction.

An expansion anchor includes a screw body, an expansion unit and a plug. The screw body has a threaded part, a header and a connecting part which connects to one end of the expansion unit. The expansion unit is shaped in a ring-like sleeve and has multiple gutters along axis direction at the other end of the unit which allows a cambered surface being formed between two adjacent gutters, where the number of cambered surfaces equals to the number of gutters. In addition, a conical plug is used to fit into the guttered end of expansion unit. The fact that screw body is separated from the plug shortens the time needed for installation and increases the degree of tightness. It achieves quick installation and firm positioning purpose.
