Without hanging type means the crane is not supplied with a hanging cable festoon system for the pendant control. Instead, the control is provided as a pendant station and a radio remote control. This is useful in workshops where a hanging cable would interfere with the load, or where the building height does not allow a festoon system. The operator can still control the crane from the floor using the pendant or from a distance using the remote.

A European spec hoist 12 t is a hoist built to European design standards with a capacity of 12 t. European style hoists are known for their compact design, low headroom, and lightweight construction. They often use modular components and are designed for easy maintenance and long service life. On this crane, the European spec hoist handles the 12 t lifting capacity. With full VFD, the hoist gives a smooth lifting speed range of 0.8–5.0 m/min, which is useful for handling delicate or precise loads. The compact size of the hoist also helps reduce the overall height of the crane, which is important when the building has limited headroom.

Full VFD on the hoist, trolley travel, and crane travel gives smooth acceleration and deceleration, precise load positioning, and lower mechanical wear. The lifting speed is 0.8–5.0 m/min, the trolley travel is 2.0–20 m/min, and the crane travel is 2.0–20 m/min, all with VFD. This gives the operator a wide range of speeds to choose from — slow for precise positioning, faster for normal travel. VFD also reduces the starting current on the motors and helps the crane run more efficiently, which is important for a crane used regularly in a factory.

BMHO = European single girder semi-gantry crane. "12t" = 12 t lifting capacity. "12m" = 12 m span. "6m" = 6 m lifting height. "A5" = ISO A5 duty class. A5 is a light to medium duty class, suitable for indoor factory use where the crane is used regularly but not continuously at full load.

P22 rail is a light rail profile used for cranes and light traveling equipment. It is matched to the 96.6 kN maximum wheel load and the A5 duty of this crane. P22 rail is easy to install, readily available, and provides a durable running surface for the wheels. For a 12 t crane with a 12 m span, P22 rail is a good match for the wheel loads and travel speeds. It is also a common rail profile in many factories, so it is easy to source and install.

The >300 mm clearance between the workshop backing (the wall or column) and the crane peak (the highest point of the crane) ensures that the crane does not hit the building structure during travel. This clearance is important for safety and for the smooth operation of the crane along the runway. The value is specified by the crane manufacturer based on the crane dimensions and the building structure. For this crane, >300 mm is required to allow for manufacturing tolerances, thermal expansion, and small movements during travel.

This crane runs on 3-phase, 380 V, 50 Hz. This covers the European spec hoist 12 t, the trolley travel motor, the two 1.5 kW long travel motors (SZW-150), the VFD drives, and the control system. If your site uses a different voltage or frequency, Yuantai can supply the crane with a custom power supply to match your local grid.
