Abstract: 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.

Abstract: The invention provides a cab roof of a vehicle with a movable panel. The cab is provided with a front windscreen, a rear deck or rear walls, and door frames at both sides. The door frames are connected with the front windscreen at the front side, with the rear decks or rear walls at the rear side, forming the enclosing sidewalls of the cab. The connecting cover is hinged with the enclosing sidewalls at the front end, and is provided with rear windscreen at the rear end. The entire cab roof is consisted of the connecting cover and the rear windscreen. A telescopic bellow is at the bottom of the cab roof, which connects the enclosing sidewalls at the lower portion. A raising and lowering device is at the bottom of the rear side of the cab roof. The vehicle can be used as a car where passengers can be seated in the rear seats, and as well as a sports car where the cab roof drops on the enclosing sidewalls by pressing the telescopic bellow.
