1. Civil engineering handover and acceptance(1) The construction unit, the supervision unit, the civil engineering unit, and the installation unit jointly participate in the acceptance of the civil engineering and go through the handover procedures.
(2) There must be a railing or barrier around the shaft to ensure safety, and its height is strictly prohibited to be less than 1.2m.
(3) According to the passage and handling space required for the elevator equipment to enter the site provided by the elevator equipment supplier, check and confirm whether there is enough space for the transportation and hoisting of the truss.
Tips→ Safety protection acceptance
Escalators and moving walks must automatically stop operating when there is no control voltage, circuit ground fault, or overload. If escalators and moving walks stop operating in the following cases, the switch must be disconnected by means of safety contacts or safety circuits.
(1) The step or pedal sags, or the tape enters the comb plate where there is a foreign object clamping, and the step, pedal or tape support structure is damaged.
(2) Parts (such as chains or racks) that directly drive steps, pedals, or tapes are broken or excessively elongated.
(3) The control device operates under the overspeed and non-manipulation reversal of the running direction.
(4) One of the multiple escalators (moving walks) installed in a row without an intermediate exit is out of operation.
(5) Additional brake action. (6) The distance between the drive and the steering device is shortened (unintentionally). (7) Handrail with entrance protection device action.
