Designed to be used in various fields; has the following features. * Compact and lightweight (lighter than a hand-operated chain block) *Speed control: Operator can control the chain speed freely as he likes by a pilot control system. *Automatic lubrication by a built-in lubricator keeps the hoist free from motor troubles. *Safe: No mechanical brake. Self-locking worm gear provides automatic and positive braking. Holds loads securely when the motor is not operating. No motor burn-out, can be overloaded, even repeatedly stalled, without damage to any parts of the chain block. Over-load will only stop the operation of the air motor. *No shock hazard: Controlled and powered completely by air. *Explosion-proof type *Required air pressure is 0.59 MPa (6 kgf/cm2).
设计用于各种领域;具有以下特征。*紧凑轻便(比手动链条块轻)*速度控制:操作者可以通过飞行员控制系统随心所欲地控制链条速度。*由内置润滑器自动润滑,使提升机不会出现马达故障。*安全:无机械刹车。自锁蜗轮提供自动和积极的制动。在电机不工作时牢牢地保持负载。电机无烧毁,可过载,甚至反复熄火,不会损坏链块的任何部分。过载只会使空气马达停止运转。*无电击危险:完全由空气控制和驱动。*防爆型*要求气压为0.59兆帕(6kgf/cm2)。
