Crane of full bore
Appointment and scope

Cranes spherical muftovy are intended for installation in quality of the locking device blocking streams of liquid and gaseous working environments on pipelines in systems water - and gas supply, the enterprises of power system, in chemical, oil processing, gas and other industries. The crane from stainless steel can be used in the food industry.
Design

The crane is spherical all-welded muftovy. The case is non-demountable. Full pass. All parts of the case are connected by welding. The crane does not demand maintenance and repair. Options of executions: 11s67p — from carbonaceous steel, 10nzh45ft, 10nzh46ft, 10nzh47ft — from stainless steel. Freely floating sphere is condensed with ftoroplastovy saddles. Saddles nestle on a sphere dish-shaped springs. The spindle, with protection against pushing out, is condensed with the ftoroplastovy rings clamped by the plug. The control of the crane is made manually by turn of the lever on 90 ° to an emphasis. In open position of the crane the lever is located along a pipeline axis. Position of the crane at installation on the pipeline — any, with a stream of a working environment in any direction.
