Q: How many kinds of lifting equipment? What are their differences?
A: The lifting equipment are mainly including hydraulic ram A, hydraulic ram B, telescopic ram and hydraulic jack sets 5/10/20. The hydraulic jack is mainly used as the auxiliary rescue equipment.

The Differences
a. Hydraulic ram A has three extra extended bars, which can extend the lifting height to facilitate the rescue process. The connection form of the extra extension bars is spiral, which can increase force bearing area to assure the high-quality load-bearing and lifting effect.
b. Hydraulic ram B has no extra extension bars. It can provide lifting force up to 120KN and make the lifting height up to 86 cm.
c. Any of the extra extension bars of hydraulic ram A can connect with hydraulic ram B to enlarge the lifting height and assure the high-quality rescue implementation.
d. Every piece of hydraulic jack of the telescopic ram can provide the lifting force up to 10 tons, while the lifting forces of hydraulic jack sets 5/10/20 are 5 tons, 10 tons and 20 tons respectively.

Q: Which hydraulic rescue equipment must work with the power packs but not double phases motor pump?
A: The hydraulic rescue equipment that must be connected to the power packs but not the double phases motor pump are including hydraulic jack, hydraulic rebar cutter, tube squeezer, hydraulic door opener and hydraulic universal plier.

Q: How many kinds of cutting equipment of products? What are their main differences?
A: The cutting equipment are mainly including hydraulic cutter A, hydraulic cutter B, hydraulic combination A, hydraulic universal plier and hand operated combi-tool.

The hydraulic cutter A is designed mainly for cutting sheet material like steel plate, while the hydraulic cutter B is fit for cutting round bar steel. The hydraulic combination A can achieve cutting and spreading operation. The hydraulic universal plier can only be connected to hand pump A. Its working head and handle can rotate 270 degrees around longitudinal center axis, which allows the hydraulic universal plier operated in small space. hand operated combi-tool has hand pump A with itself and has no need for outer power source. The working head and the pump can achieve 360-degree transverse rotation to facilitate the cutting and spreading operation in any direction.

Q: What are the differences among the hydraulic combination A, hand operated combi-tool and hydraulic wedge jack?
A: All these three kinds of rescue equipment have the function of spreading. But only hydraulic combination A and hydraulic wedge jack can work with the double phases motor pump. Compared with the hydraulic spreader, the hydraulic combination A has the function of cutting and spreading. While the hydraulic wedge jack is mainly used to open the narrow seam or the doors and windows to allow the other rescue equipment achieving the further rescue operation. It can cooperate with the hydraulic spreader to accelerate the rescue process.
