Abstract: A portable table top welder for welding plastic material webs, the portable table top welder including a frame including a carrier housing and a support arm at which a welding device is arranged; at least one transport roller including a rotatable transport roller axle and at least one contact pressure roller that is rotatably supported at the carrier housing, wherein a weight is arranged at an eccentrical element which is rotatably connected at one side by a concentrically supported eccentrical element axle at the carrier housing and rotatably connected at another side by an eccentrically supported contact pressure roller axle at the contact pressure roller. The table top welder handles and transports easily and can be mounted on a table or on another carrier structure in a disengageable manner.

Abstract: A safety brake for an elevator system having at least one traveling body movable in an elevator shaft along a guide rail and/or a brake rail. The safety brake is suitable for braking and retaining the traveling body on the guide and/or brake rail as required. The safety brake includes a control plate for receiving a brake body and for positioning the brake body relative to the guide and/or brake rail. The brake body is designed in at least two pieces and includes a first brake element and a second brake element. The first brake element is solely for braking and retaining purposes when the traveling body is moving along the guide and/or brake rail in an upward direction, and the second brake element is solely for braking and retaining purposes when the traveling body is moving along the guide and/or the brake rail in a downward direction.

Abstract: A brake device for an elevator system with a travel body movable in an elevator shaft along a guide and/or brake rail brakes and retains the travel body on the rail as required. The brake device includes a control plate receiving a brake body and for positioning the brake body relative to the rail. The brake body has first and second brake elements pivoted about a common axis. The first brake element is for braking and retaining purposes when the travel body is moving along the rail in an upward direction, and the second brake element is for braking and retaining purposes when the travel body is moving along the rail in a downward direction.
