1. Operative part composed by a load lift system welded steel frame capacity up 1T5, protected by a casing of anodized aluminum profile attached to the system. The set is equipped with an access door with safety contact for setting up the crate and directional locking castors for easy movement of the set.

2. Inductive sensors limit switches' top and bottom: maximum stroke: 1600mm approx.

3. Inductive sensors top and bottom slowdown, adjustable position.

4. The electrical control box and hydraulic unit on independent frame aluminum profile, mounted on directional locking castors. The box is composed of motor circuit breakers and differential 30mA, contactors, security module preventa, PLC (software & backup provided), integrates the control panel with switches for the passage of normal / differential mode, manu / auto / continuous Up -acy / Down-dcy buttons, signaling the state of the machine by tricolor indicator glass, switch, emergency stop, etc ... Stainless steel retention tank for drips

5. Hoses equipped with self closing flat face couplers to connect the plant to the cylinder and quick connector Harting type to connect the position sensors and security of the operative part to the electric box.

6. Cylinder 800mm stroke with double chain system (secured reeving) to obtain a consistent stroke 1600mm for good visualization of slowdown phases and the differential mode. Parachute valve (load holding function)

7. Set of poppet valve logic range 16, control with electrodistributors, type cartridge for mounting on drilled block positioned at chest height, with pressure taps and flow rate. Function balancing, regulating of controlled flow rate (slow and fast speed).

8. Hydraulic plant of 4Kw, 1500T/min and 20L/min, 75L tank, equipped with pressure limiter, return filter with clogging indicator, visual and electrical low level, thermostat, etc ...
