1. Aluminum alloy ladderWhat preparations should be done before use
1. Ensure that all rivets, bolts, nuts, and movable parts are tightly connected, the ladder column and step are firm and reliable, and the extension circlip and hinge are in good working condition;
2. Keep the ladder clean and free of slippery substances such as grease, oil, wet paint, mud, and snow;
3. The operator’s shoes are kept clean, and leather-soled shoes are prohibited.
When climbing aluminum ladders up and down, people must face the ladder and use the three-point contact climbing method (Ie use both hands and one foot, or one hand and both feet), only one person can stand on a single-width ladder at a time. Do not lean on one side, keep the center of gravity in the middle of the ladder, use the tool belt to carry the tool, or use the rope to hoist or hang the tool. To ensure that there is no oil stains and mud on the bottom of the boots and the crosspieces, use the three-point contact climbing method at all times. If you must place a ladder in front of the door, lock or block the door first.
Only use heavy-duty ladders approved by relevant standards. The top of the ladder must be placed in a stable place. The top of the ladder (folding ladder is not included) must be higher than the The safety platform or retaining wall is about one meter over. The slope of the ladder must be a ratio of 4 (height from the ground) to 1 (distance from the wall). Metal ladders can conduct electricity, so they must be kept away from wires and power sources when in use. Follow the manufacturer's instructions to ensure that the overlapping part of the ladder is safe, tie up the safety rope, and place the ladder on a stable surface. Make sure that the lock of the ladder is properly locked. The round head pull studs on the aluminum alloy ladder can be made of aluminum or iron, but the hardness of aluminum and iron are different.
Aluminum alloy ladder, if iron material is used, the riveting effect may not be satisfactory. Also One point, aluminum alloy ladders do not require very high riveting requirements. Aluminum materials are good. Aluminum round studs are relatively cheaper. After checking the status of the ladder, please carefully confirm that all hinges are in the locked position It can be used only when the lock block is in position. If there is a hinge with the lock block in place, open its symmetrical hinge, then fold the ladder column inward for about 40 degrees, and then expand it outward to lock the pair of hinges. Check that the ladder is in use. After that, please carefully confirm that all hinges are in the locked position before using it. If there is a hinge with a lock block in position, open its symmetrical hinge, then fold the ladder column inward about 40 degrees, and then unfold it to make it The pair of hinges are locked.
The elevator should strictly follow its regulations Work with a high load capacity, work may cause damage to personnel and goods; working on a lift without safety fences will cause personnel to fall and cause personnel. To ensure that the lift is in good working condition, perform performance inspection before use: Whether the control button is effective; whether the power cord and socket are intact; whether the oil pipeline is intact; the stability of the guardrail; the tightness of the bolts at each junction; the appearance quality is intact.
