1- LIFTING MOTOR
The hoist has a cylindrical short circuit motor with an incorporated electromagnetic brake.
The motor and brake have been designed for continuos service with high duty factors and cycles.
The brakes are electromagnetic disc, with asbestos free flat faced linings. They offer great reliability and automatic braking in the event of power failure. The friction linings are long lasting and the brake is easy to regulate.
Robust and compact, situated on the exterior, allowing ease of access.
The helical teeth in all the gears are cut with great precision, in cemented steel, assuring silent running, great reliabilty and long life.
The drive from the motor to the gearbox is direct, avoiding coupling devices which have a tendancy to fail.
All of the gears are lubricated by an oil bath in the interior of a closed casing, machining of the gear locations is made by high precision machine tools.
3- DRUM & ROPE GUIDE
The drum is designed and manufactured according to FEM 966 standard.
Constructed from a seamless steel tube with grooves machined according to DIN 15061. The groove is machined dependant on the wire rope exits i.e. 1 or 2 exits.
The drum is fitted to the hoist frame using high quality, self lubricating, comercial bearings. The drive from the gearbox to the drum is via a direct splined shaft.
The rope guide is manufactured from GGG 70 nodular cast iron with self lubricating graphite, which also gives particular resistance to wear.
The rope guide is formed by two pieces, which can easily be assembled without special tools.
4- OVERLOAD LIMIT DEVICE
All of our hoists are fitted with an electro-mechanical load cell as standard (electronic control). This load cell consists mainly of 2 parts:
- A electronic cell pin.
- Load cell unit (to be installed in the electric panel).
5- LIMIT SWITCH
Is located in the drum axle. It limits hook movement in the up and down motions.
All of our hoists are fitted with a security limit switch in lifting, preventing a possible failure of the main limit switch.
