English to Russian Tech/Engineering Engineering (general) FLIGHTDECK INTRUSION RESISTANCE

Добрый день!
Помогите, пожалуйста, перевести "door handle pulling equipment" в следующем контексте:

Test Equipment.
(1) The ram must be a pendulum system with a steel weight of at least 45 kg (99.2 lb), capable of delivering horizontal impacts of at least 300 Joules (221.3 ft•lbf). Figure 3 illustrates the arrangement of this pendulum system in both the pre-release and impact position. The ram is a steel cylinder 15.2 cm (6 in) in diameter and 39.4 cm (15.5 in) long. The striking end of the weight must be hemispherical and have a diameter of approximately 15.2 cm (6 in), as shown in Figure 3. The impact nose used in this equipment can be made from cast epoxy-polyamide resin. However, any durable impact resistant material is satisfactory. The suspension system for the door ram consists of four flexible steel cables providing a swing radius of 171 cm (5.61 ft), as shown in Figure 4. These cables are adjusted to equal length through turnbuckles such that the ram swings in a straight, true arc and are attached to a rigid frame that is adjusted to level.

(2) It is convenient to clamp the pendulum system to the forks of a forklift truck, which allows rapid horizontal and vertical adjustment of the impact point of the ram. A winch and snap ring system may also be used to raise and pull back the door ram. The use of a calibrated elevation stand is a convenient means of quickly and reproducibly establishing the proper ram elevation for each required impact.

(3) The impact energy must not be less than the prescribed value.

(4) The door handle pulling equipment must be capable of attaching to the doorknob or handle and providing the required tension load without slippage. The equipment may be hydraulic or mechanical and must include a load cell, strain gauge, or other calibrated load-measuring device.

Заранее спасибо!
