    MAIN STRUCTURE & RUNNING PRINCIPLE 2.2 Main structure and Running Principle of the Model CD1 & MD1 Electric Hoist The hoist is formed of three parts. Hoisting Mechanism, Traversing Mechanism (stationary type has no trolley), Electric Control De- vice. MDI electric hoist is supplied with the base frame of CDI electric hoist. The hoisting motor is changed to double motor providing normal and slow lifting speeds.
  • Page 16 MAIN STRUCTURE & RUNNING PRINCIPLE The small motor is connected with the big motor through the Creep Driving Mechanism. While the small motor is turned on, the tapered brake in it is open. The small motor runs at the speed of 1380 r/min., the speed is decreased by the Creep Driving Mechanism which drives the fan braking wheel (combined with the rotor of big motor for running) and rotor of big motor turning together.

    MAIN STRUCTURE & RUNNING PRINCIPLE 2.2.2 Traversing Mechanism Through the traversing reducer, the motor drives a pair of driving wheels of the trolley, causing the hoist moving under along I beam rail. The traversing motor is also a conic rotor motor with brake device. A flat brakering is used for the brake so that the braking torque is comparative smaller, and the braking process slow to avoid the load from vacillation when stopping the trolley.

    INSTALLATION AND ADJUSTMENT 3. INSTALLATION AND ADJUSTMENT 3.1 INSTALLATION 3.1.1 When the hoist is shipped to the installation site, to care that no damage has been done during the transportation. 3.1.2 The hoist runs with the fixed and standard rail(see Table 1a,1b). In order to match the variable I beam rails, user should select standard rail referring the tables or design by themselves ( the rail must be in compliance with related standard).While installing, the width between traversing wheels can be adjusted with Gaskets P (See Fig.1).
  • Page 31: Inspection And Test

    INSPECTION AND TEST 4. INSPECTION AND TEST 4.1 Check whether all the locations of lubrication have been sufficiently greased. (Ref. to Table 3, Table 4). 4.2 Check whether the hoist and rail has been connected reliably. 4.3 The step-down of power voltage must not be less than 90% at the installation site (Care must be taken to avoid the voltage from excessive reducing caused by long length or small section of cable).
  • Page 32: Precaution And Trouble-Shooting

    PRECAUTION AND TROUBLE-SHOOTING 5 . PRECAUTION AND TROUBLE-SHOOTING 5.1 PRECAUTION 5.1.1 The electric hoist should be operated by such person who should understand the structure and properties of the hoist and be familiar with the safety and operation regulations. 5.1.2 The space limiter is a security device for preventing the hook from exceeding the limit position when it moves up or down. It should not be used frequently as a path switch.
