Installation

Voltage
Note
If the voltage of the power supply is over or less than 10% of the standard voltage to operate the hoist under the abnormal voltage will result in motor damage, hence, before an operation , be sure to confirm whether the voltage of the power supply is within the standard range.

Warning

• It is forbidden to link the power supply before the completion of installation.
• Before installing the hoist, please confirm the whole upper hook assembly has been firmly assembled to the hoist body (ensure the chain connection pin is installed properly).
• Remarks: If the hoist is equipped with an electric trolley, the first step (to separate the upper hook from the hoist body) can be omitted, and it is only required to install the hoist between two side plates of the trolley and lock the upper hook.
• Assemble the chain bag (Fig.4.1) Link the power supply and operate the push button. The procedure should be performed by a professionally trained person. (Fig.4.2)

Operation Test

• Press the(S) push button to lower the hoist until the limit spring touches the limit switch, and the motor will stop automatically.
• Press the(D) button until the chain is totally in the chain bag and the motor stops . c) Test the function of the emergency stop switch (if the emergency stop switch is selectively purchased )Press button (J) or (S), and press the emergency stop switch at the same time to check whether the hook can stop immediately.When the emergency switch is pressed,there will be no response when any other button is pressed. Finally, turn the emergency switch in clockwise and it will bounce back to the original position . When it bounces back, the hoist can be operated again if any of the above-mentioned tests is abnormal, it is required to check the distribution circuit and the self-locking of the emergency switch.
• Check the direction of the chain. All welding points should be in the same direction. (Fig 4.3). The operation can not be utterly proper unless all the welding points of the chain are in the same line.

Note

• If the chain fall is double or every number, it is forbidden to hang the lower hook in the reverse direction to avoid dangers(Fig. 4.4).
• Chain lubrication
• The degree of chain lubrication plays an important role in the chain’s service life . It needs to apply machine oil or gear oil regularly to prolong the chain’s service life.
• The process of lubrication:
• Keep the chain vertically without load.
• Erase dust and water stains on the chain.
• Lubricate each link of the chain connection and load the pulley. After the lubrication, lift the chain up and down without load to daub lubrication equably. (Fig.4.5)
