HS-VT系列手拉葫芦的8大特点使其具备了高性能、高安全性又充满了灵活性，巧夺天工，自成一派，让您更轻松、方便的完成工作，大大减轻您的劳动强度。 1、齿轮：日本技术对称排列高速同步齿轮，比普通葫芦耐磨度增加一倍，转动更平稳，手拉力更轻。 2、链条：更高强度的链条，对口处焊接精细，经过中频感应淬火处理，符合ISO3007-1984国际标准链条技术；适应突发超重作业；拉链手感好，改变普通葫芦只能垂直向下拉的弊端，能从多方向、呈45度角拉拽，适应范围更大。 3、吊钩：高强度足料足钩，高级合金材料，使承受以外超负荷工作时不发生断裂，只是逐渐变形，安全系数更高；钩头处安全的设计使货物不会脱钩。 4、极限开关：吊上吊下都有极限开关部件，防止链条超出，确保安全。 5、部件：主要部件都采用优质合金钢，实施严格尺寸、质量检查，保证每一部件的性能充分发挥。 6、机身：纤细，设计新颖，大方美观，符合人体工程学。机身轻，工作活动界面小，适应环境广。 7、喷塑：先进的喷塑处理工艺，里外都挂塑，使用后表里都崭新如初。 8、罩壳：精钢压制罩壳，坚固中显轻巧。 另外我公司还生产各种规格的链条，钩子，起重滑车等。

HS-VT series chain blocks 8 characteristics make them have high ability and security, high agility, and this greatly reduced word intension.

1. Gear: they are innovated symmetrical arrayed high speed synchronous gears, and are made for international standard gear steel. Compared with common gears, they are more wearable and steadier, and more laborsaving.

2. Chain: adopts high strength chain and high precision welding technology meet ISO3077-1984 international standard; fits for gusty overload work conditions; takes your hands a better feeling ; multi-angle operation(with45°) .

3. Hook: made of high –class alloy steel, it has high strength and high security; by using new design, weight will never escape.

4. Limit Switch: using limit switch components in designation to protect chain and ensure security.

5. Components: main components are all made of high –class alloy steel, with high precision and security.

6. Framework: slight design and more beautiful; with less weight and smaller work area.

7. Plastic Plating: by adopting advanced plastic plating technology inside and outside, it looks like a new one after years of operation.
