Specialising in providing large integrated security solutions, Tate Security Technology Ltd had a project to retro fit a new sliding door arrangement into existing staff and visitor doors for prison gatehouses. In a number of cases, HepcoMotion’s previous generation GV3 slides were being used as the original sliding mechanism for these sliding doors. While the slides and racks were in good working order, the surrounding installations were in need of updating or replacement. The customer was looking for a new simple to install and low maintenance system that would fit into the existing envelope. Taking into account the security needs of prison doors, the system needed to be durable, provide a long service life & have a minimal installation downtime, to reduce the disruption in the high traffic area of a gatehouse.
Hepco’s DLS4 linear drive fits the bill perfectly. With a high load capacity and low maintenance, the DLS4 features Hepco’s well renowned V guide technology offering quiet, trouble free operation. This system utilises two carriages to give the customer a suitable mounting position for the door assembly, and offers a smooth, low friction operation.
Flexible and user friendly, the DLS4 allows Tate Security to position the motor and electrical control system equipment, as the application requires. This complete off the shelf mechanical package saves hours in design and specifying time and can be integrated into existing control systems or as a new installed package. The system is available in any length to 8m as standard; ensuring varying door sizes can be accommodated. This was important for the customer as the length of the unit changes with each installation.
Scope of supply
Generally the scope of supply is below however the length of the unit changes with the installation:
1 x HepcoMotion DLS4 Belt Driven Unit, fitted with 2 Short Style Carriages both fitted with Switch Cam on same side as Motor Beam Length = 2100mm fitted AC Geared Motor with nominal linear speed of 0.23m/s, 0.25kW, 400V, 3 phase, 20:1 reduction with torque limiter Position 2 and handing C3.
DLS4 ASSEMBLY COMPRISING OF 1 X DLS4 2100 S2WO, 2 X DSC4, 1 X WG4 R20 T 2 M71S4 C3
The whole system is very low maintenance, as V technology only requires small amounts of lubricant to spread over the vee guide surfaces to achieve a long and trouble free life.
The customer has now installed 15 units into a number of private & public sector prisons, with senior prison management commenting on how smooth, quiet and reliable the system is. Following the success of these projects, Tate Security has a number of orders, to install new systems in the early part of next year.
