4) Scope of Supply
- 1 complete set of cable connecting device (plug and socket)
- 1 pc motor: 380 V, 50Hz,37Kw
- 1 pc high pressure hydraulic pump
- 1 set control block (SUN, imported), including by pass system to avoid
overheating of hydraulic components. (Remark:Check valve is
installed to avoid grab open due to power fail)
- 1 set of special tools (two connectors for pressure meter mating
pipe, one special wrench)
- 1 set of cable drum, 15m cable, electric box
- Material of shells is Q345B; material of all axes is 42CrMo, by tempering and
grinding. Material of lips is NM400 or Q345B, alloy build up welding, and the rigidity should be reach HRC50.
- The holes of up beam,pole,low beam and scoops are bored by machine, it can ensure the
concentric,detailed allowance error according to drawing request.
- All steel plates should be sandblasting before machining.
- All turning joints lubrication should be taken into account , oil nipple should be designed for avoiding damages. The connecting
joints of the cylinders should be spherical, and need lubrication.
- All important load-carrying positions should beveling,and all welding lines should be carried out nondestructive test, and the welding lines’s grade must reach 1st level.
- The hydraulic system and the parts -- like the hydraulic cylinders,valves and so on will select famous brand.
- The grab should act accurately, operation should be flexible, no noises.
- Whole dimension deviation of grab should be not more than 10mm, main installation dimension deviation be not more than 3mm.If there are special requests, machining according to drawing.
- All the grabs are directly linked to the hooks of the cranes. When
designed the grabs should consider the dimensional coordination.The grabs are connected with the hook of the cranes through chain links. The strength of the links should lift the 3 times weight in security (including the dead weight and
the holding material weight).
- As for the installation position of all quick-wear parts,
replacement convenience should be taken into account.
- Each grab should be marked with GBM logo, grab manufacture number and volume
- Other unmentioned technical requirements should be in accordance with the grab manufacture standard of Ministry of Communications and enterprise’s execution standard .
- All the surface of the steel structure is sandblasting to Sa2.5

- Middle coat (Epoxy resin paint) app. 80µm
- Top coat (Polyurethane paint) app. 40µm.
- Color of top paint: according to the customer.
- Steel plates cutting adopts NC cutting .
- Adopt gas shielded welding.
