No. 1 in the world for hydraulic lift components production Direct acting at side 1001 jackis especially developed for small 2 - 3 storey buildings. A large range of diameters isavailable to meet any load requirement. The 1001 jack is also suitable for heavy load installations or elevators with big cars requiring twin jacks. This jack can be supplied in two pieces with a threaded joint.The jack is equipped with anupper swivel plate for the con- nection to the car frame and with a bottom plate for the location in the pit. On request the bottom plate can be fixed at a certain dis- tance from the cylinder bottom, thus allowing its partial burial or, alternatively, the jack can be supplied without bottom plate.Jack type 1001 SL is availablefor diameters 60 to 110.The new technology applied tothis SL jack type achieves a considerable reduction of the cylinder diameter, resulting in the employment of a lower quantity of oil and decrease of the lift elasticity. A new design of cylinder joint equipped with a collar, allows a quicker installation of the jack. >
