    • A crimping and cutting device for use on pipes comprises a frame (1) provided at one end with an anvil (4) to locate a pipe (P) during a crimping and cutting operation. The device includes a crimping head (18) and a cutting blade (28) which are movable towards the anvil (4) by, respectively, first and second hydraulic actuators (11, 13). The two actuators are mounted coaxially on the frame (1), with the first actuator (11) being operatively connected to the second actuator (13). In operation, the first actuator (11) is operated to move the second actuator (13) which, in turn, moves the crimping head (18) so as to compress the pipe against the anvil (4). Then the second actuator (13) is operated to move the cutting blade (28) through a passage (35) formed in the crimping head (18) so that the blade cuts through the compressed region of the pipe (P).
    • 用于管道的压接和切割装置包括在一端具有砧座(4)的框架(1),用于在压接和切割操作期间定位管道(P)。 该装置包括可分别通过第一和第二液压致动器(11,13)向砧座(4)移动的压接头(18)和切割刀片(28)。 两个致动器同轴地安装在框架(1)上,第一致动器(11)可操作地连接到第二致动器(13)。 在操作中,第一致动器(11)被操作以移动第二致动器(13),其又使压接头(18)移动,以将管道压靠在砧座(4)上。 然后,第二致动器(13)被操作以通过形成在压接头(18)中的通道(35)移动切割刀片(28),使得刀片切穿管(P)的压缩区域。

    • A secure inlet cap protecting the inlets of a fire department connection from blockage and damage. The secure inlet cap includes a cover and lock, each having at least one tab that engages the posts of the swivels of the fire department connection inlets. When fitted over the posts and assembled with tamper-proof fasteners, the secure inlet cap securely prevents access to the inlet. In non-emergency situations, the secure inlet cap may be removed without damage by removing the fasteners. The lock includes a tool slot receiving a tool that allows the secure inlet cap to be quickly pried loose by applying force to the fasteners. Deformable areas in the cover give way when sufficient prying force is applied breaking the hold between the fasteners and the cover and allowing the cover and the lock to be separated and removed from the swivel.
    • 一个安全的入口盖,保护消防部门的入口免受堵塞和损坏。 安全入口盖包括盖和锁,每个具有与消防部门连接入口的旋转件的柱接合的至少一个突片。 当安装在柱上并组装有防篡改紧固件时,安全入口盖可以牢固地防止进入入口。 在非紧急情况下,可以通过拆卸紧固件来拆卸安全入口盖,而不会造成损坏。 该锁包括工具槽,其接收工具,其允许通过向紧固件施加力来快速地将安全入口盖松脱。 当施加足够的撬力力来破坏紧固件和盖子之间的保持并允许盖子和锁定件从旋转件分离和移除时,盖子中的可变形区域给出方式。
