5th, most operation teams have all removed small device for hoisting in real work, random placement may cause insulating cord by
Damage, insulate oil return blockage, situations such as causing to ignore maintenance to small lifting rope rope, load test;
6th, small to be hung in when slinging wire and bearing wire tension, the insulation arm of aerial lift device with insulated arm can not adjust height and water
Prosposition is put, and only by the position for adjusting working bucket, makees triangle arrangement or horizontally arranged overhead distribution dress changing three-phase conducting wire
During the interphase pillar insulator put, staff is difficult to find suitable job position;7th, in the vertical arrangement double loop same feeling
Set up straight line lever apparatus on, in replacing, lower floor's pillar insulator when, aerial lift device with insulated arm activity space is narrow and small, with upper strata cross-arm
Safe distance deficiency;
8th, on the straight corner bar less than 15 °, because wire has the horizontal pull for pointing to interior angle side, the danger for running line be present
Danger.If aerial lift device with insulated arm is in exterior angle side position, small hang will bear outside horizontal pull, and this is that aerial lift device with insulated arm uses
When forbid;And it is that wire will touch insulation bucket that aerial lift device with insulated arm, which is in interior angle side position, cause safe distance insufficient, simultaneously
Insulation bucket, which bears horizontal side force, may damage its level(l)ing device;
9th, big in line span, when temperature is relatively low, small arm or strut lifting lead wire is by by power very big downwards, possibility
Beyond maximum load rating.
